The Blickensderfer typewriter was invented by George Canfield Blickensderfer (1850–1917) and patented on April 12, 1892. Blickensderfer was a nephew of John Celivergos Zachos , the inventor of the stenotype . Two models, Model 1 and Model 5, were unveiled to the public at the 1893 World's Columbian Exposition in Chicago. The Model 5 was a stripped-down version of the bigger, more complex Model 1. These machines were intended to compete with larger Remington , Hammond and Yost typewriters , and were the first truly portable, full-keyboard typewriters. The design also enabled the typist to see the typed work, at a time when most typewriters were understrike machines that concealed the writing. When Blickensderfer unveiled his small Model 5, its compactness and novel features attracted huge crowds and many orders.
176-547: The Blickensderfer typewriters were initially manufactured in a rented factory on Garden Street in Stamford, Connecticut. By 1896, due to strong foreign demand in particular for his machines, Blickensderfer opened a new and modern factory on Atlantic Street in Stamford. According to an article published by the Stamford Historical Society, "Blickensderfer's typewriter ... became the world's best seller, and
352-491: A precipitate of aluminium hydroxide , Al(OH) 3 , forms. This is useful for clarification of water, as the precipitate nucleates on suspended particles in the water, hence removing them. Increasing the pH even further leads to the hydroxide dissolving again as aluminate , [Al(H 2 O) 2 (OH) 4 ] , is formed. Aluminium hydroxide forms both salts and aluminates and dissolves in acid and alkali, as well as on fusion with acidic and basic oxides. This behavior of Al(OH) 3
528-525: A "less classical sound". This name persisted: although the -um spelling was occasionally used in Britain, the American scientific language used -ium from the start. Most scientists throughout the world used -ium in the 19th century; and it was entrenched in several other European languages, such as French , German , and Dutch . In 1828, an American lexicographer, Noah Webster , entered only
704-853: A Christian in the event of victory against the Visigothic Kingdom , which was said to have guaranteed the battle. Clovis regained the southwest from the Visigoths and was baptised in 508. Clovis I was the first Germanic conqueror after the Fall of the Western Roman Empire to convert to Catholic Christianity; thus France was given the title "Eldest daughter of the Church" by the papacy, and French kings called "the Most Christian Kings of France". The Franks embraced
880-425: A European counterweight between American and Soviet spheres of influence. However, he opposed any development of a supranational Europe , favouring sovereign nations . The revolt of May 1968 had an enormous social impact; it was a watershed moment when a conservative moral ideal (religion, patriotism, respect for authority) shifted to a more liberal moral ideal (secularism, individualism, sexual revolution). Although

(Another article in the same journal issue also refers to the metal whose oxide is the basis of sapphire , i.e. the same metal, as to aluminium .) A January 1811 summary of one of Davy's lectures at the Royal Society mentioned the name aluminium as a possibility. The next year, Davy published
1232-561: A chemistry textbook in which he used the spelling aluminum . Both spellings have coexisted since. Their usage is currently regional: aluminum dominates in the United States and Canada; aluminium is prevalent in the rest of the English-speaking world. In 1812, British scientist Thomas Young wrote an anonymous review of Davy's book, in which he proposed the name aluminium instead of aluminum , which he thought had
1408-759: A combination of social, political and economic factors, which the Ancien Régime proved unable to manage. A financial crisis and social distress led in May 1789 to the convocation of the Estates General , which was converted into a National Assembly in June. The Storming of the Bastille on 14 July led to a series of radical measures by the Assembly, among them the abolition of feudalism , state control over
1584-569: A coup and civil war. During the May 1958 crisis , the weak Fourth Republic gave way to the Fifth Republic , which included a strengthened presidency. The war concluded with the Évian Accords in 1962 which led to Algerian independence , at a high price: between half a million and one million deaths and over 2 million internally-displaced Algerians. Around one million Pied-Noirs and Harkis fled from Algeria to France. A vestige of empire

With the brilliant chief engineer and designer gone, his company could not continue, and the heirs sold it in 1919. After several unsuccessful years under different ownership, the Remington Typewriter Company acquired the assets, including tools, parts, drawings and intellectual rights, from
2288-465: A more covalent character. The strong affinity of aluminium for oxygen leads to the common occurrence of its oxides in nature. Aluminium is found on Earth primarily in rocks in the crust , where it is the third-most abundant element , after oxygen and silicon , rather than in the mantle , and virtually never as the free metal . It is obtained industrially by mining bauxite , a sedimentary rock rich in aluminium minerals. The discovery of aluminium
2464-631: A number of new patents were filed for the Blickensderfer 5 up to June 1, 1897, when the machine largely remained the same for the balance of its production life. Blickensderfer continued to invent new machines until his death, including the Blickensderfer Electric and various standard machines with the Blickensderfer 9 being his last major new model. The typewheel, like the later typeball of the IBM Selectric typewriter ,
2640-532: A period of economic prosperity and cultural and scientific flourishing known as the Belle Époque . France was one of the major participants of World War I , from which it emerged victorious at great human and economic cost. It was among the Allies of World War II , but it surrendered and was occupied in 1940. Following its liberation in 1944 , the short-lived Fourth Republic was established and later dissolved in
2816-441: A probable cause for it being soft with a low melting point and low electrical resistivity . Aluminium metal has an appearance ranging from silvery white to dull gray depending on its surface roughness . Aluminium mirrors are the most reflective of all metal mirrors for near ultraviolet and far infrared light. It is also one of the most reflective for light in the visible spectrum, nearly on par with silver in this respect, and
2992-683: A process termed passivation . Because of its general resistance to corrosion, aluminium is one of the few metals that retains silvery reflectance in finely powdered form, making it an important component of silver-colored paints. Aluminium is not attacked by oxidizing acids because of its passivation. This allows aluminium to be used to store reagents such as nitric acid , concentrated sulfuric acid , and some organic acids. In hot concentrated hydrochloric acid , aluminium reacts with water with evolution of hydrogen, and in aqueous sodium hydroxide or potassium hydroxide at room temperature to form aluminates —protective passivation under these conditions
3168-525: A refractory material, and in ceramics , as well as being the starting material for the electrolytic production of aluminium. Sapphire and ruby are impure corundum contaminated with trace amounts of other metals. The two main oxide-hydroxides, AlO(OH), are boehmite and diaspore . There are three main trihydroxides: bayerite , gibbsite , and nordstrandite , which differ in their crystalline structure ( polymorphs ). Many other intermediate and related structures are also known. Most are produced from ores by
3344-474: A stable noble gas configuration. Accordingly, the combined first three ionization energies of aluminium are far lower than the fourth ionization energy alone. Such an electron configuration is shared with the other well-characterized members of its group, boron , gallium , indium , and thallium ; it is also expected for nihonium . Aluminium can surrender its three outermost electrons in many chemical reactions (see below ). The electronegativity of aluminium
3520-820: A variety of wet processes using acid and base. Heating the hydroxides leads to formation of corundum. These materials are of central importance to the production of aluminium and are themselves extremely useful. Some mixed oxide phases are also very useful, such as spinel (MgAl 2 O 4 ), Na-β-alumina (NaAl 11 O 17 ), and tricalcium aluminate (Ca 3 Al 2 O 6 , an important mineral phase in Portland cement ). The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3 ), selenide (Al 2 Se 3 ), and telluride (Al 2 Te 3 ). All three are prepared by direct reaction of their elements at about 1,000 °C (1,800 °F) and quickly hydrolyze completely in water to yield aluminium hydroxide and
3696-575: A way of purifying bauxite to yield alumina, now known as the Bayer process , in 1889. Modern production of aluminium is based on the Bayer and Hall–Héroult processes. As large-scale production caused aluminium prices to drop, the metal became widely used in jewelry, eyeglass frames, optical instruments, tableware, and foil , and other everyday items in the 1890s and early 20th century. Aluminium's ability to form hard yet light alloys with other metals provided

#17327831529173872-734: Is Al : while it was present along with stable Al in the interstellar medium from which the Solar System formed, having been produced by stellar nucleosynthesis as well, its half-life is only 717,000 years and therefore a detectable amount has not survived since the formation of the planet. However, minute traces of Al are produced from argon in the atmosphere by spallation caused by cosmic ray protons. The ratio of Al to Be has been used for radiodating of geological processes over 10 to 10 year time scales, in particular transport, deposition, sediment storage, burial times, and erosion. Most meteorite scientists believe that
4048-434: Is Al. Al was present in the early Solar System with abundance of 0.005% relative to Al but its half-life of 728,000 years is too short for any original nuclei to survive; Al is therefore extinct . Unlike for Al, hydrogen burning is the primary source of Al, with the nuclide emerging after a nucleus of Mg catches a free proton. However, the trace quantities of Al that do exist are the most common gamma ray emitter in
4224-407: Is paramagnetic and thus essentially unaffected by static magnetic fields. The high electrical conductivity, however, means that it is strongly affected by alternating magnetic fields through the induction of eddy currents . Aluminium combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has
4400-483: Is 1.61 (Pauling scale). A free aluminium atom has a radius of 143 pm . With the three outermost electrons removed, the radius shrinks to 39 pm for a 4-coordinated atom or 53.5 pm for a 6-coordinated atom. At standard temperature and pressure , aluminium atoms (when not affected by atoms of other elements) form a face-centered cubic crystal system bound by metallic bonding provided by atoms' outermost electrons; hence aluminium (at these conditions)
4576-636: Is a founding and leading member of the European Union and the eurozone , as well as a member of the Group of Seven , North Atlantic Treaty Organization (NATO), Organisation for Economic Co-operation and Development (OECD), and Francophonie . Originally applied to the whole Frankish Empire , the name France comes from the Latin Francia , or "realm of the Franks ". The name of

The system, however, is not shared by the other members of its group: boron has ionization energies too high to allow metallization, thallium has a hexagonal close-packed structure, and gallium and indium have unusual structures that are not close-packed like those of aluminium and thallium. The few electrons that are available for metallic bonding in aluminium are
4928-522: Is almost never found in the elemental state; instead it is found in oxides or silicates. Feldspars , the most common group of minerals in the Earth's crust, are aluminosilicates. Aluminium also occurs in the minerals beryl , cryolite , garnet , spinel , and turquoise . Impurities in Al 2 O 3 , such as chromium and iron , yield the gemstones ruby and sapphire , respectively. Native aluminium metal
5104-405: Is also easily machined and cast . Aluminium is an excellent thermal and electrical conductor , having around 60% the conductivity of copper , both thermal and electrical, while having only 30% of copper's density. Aluminium is capable of superconductivity , with a superconducting critical temperature of 1.2 kelvin and a critical magnetic field of about 100 gauss (10 milliteslas ). It
5280-553: Is extremely rare and can only be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes. Native aluminium has been reported in cold seeps in the northeastern continental slope of the South China Sea . It is possible that these deposits resulted from bacterial reduction of tetrahydroxoaluminate Al(OH) 4 . Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of
5456-536: Is greatly reduced by aqueous salts, particularly in the presence of dissimilar metals. Aluminium reacts with most nonmetals upon heating, forming compounds such as aluminium nitride (AlN), aluminium sulfide (Al 2 S 3 ), and the aluminium halides (AlX 3 ). It also forms a wide range of intermetallic compounds involving metals from every group on the periodic table. The vast majority of compounds, including all aluminium-containing minerals and all commercially significant aluminium compounds, feature aluminium in

5632-492: Is in fact more basic than that of gallium. Aluminium also bears minor similarities to the metalloid boron in the same group: AlX 3 compounds are valence isoelectronic to BX 3 compounds (they have the same valence electronic structure), and both behave as Lewis acids and readily form adducts . Additionally, one of the main motifs of boron chemistry is regular icosahedral structures, and aluminium forms an important part of many icosahedral quasicrystal alloys, including
5808-409: Is known to metabolize aluminium salts , but this aluminium is well tolerated by plants and animals. Because of the abundance of these salts, the potential for a biological role for them is of interest, and studies are ongoing. Of aluminium isotopes, only Al is stable. This situation is common for elements with an odd atomic number. It is the only primordial aluminium isotope, i.e.
5984-500: Is negligible. Aqua regia also dissolves aluminium. Aluminium is corroded by dissolved chlorides , such as common sodium chloride , which is why household plumbing is never made from aluminium. The oxide layer on aluminium is also destroyed by contact with mercury due to amalgamation or with salts of some electropositive metals. As such, the strongest aluminium alloys are less corrosion-resistant due to galvanic reactions with alloyed copper , and aluminium's corrosion resistance
6160-521: Is not as important. It is a polymer with the formula (AlH 3 ) n , in contrast to the corresponding boron hydride that is a dimer with the formula (BH 3 ) 2 . Aluminium's per-particle abundance in the Solar System is 3.15 ppm (parts per million). It is the twelfth most abundant of all elements and third most abundant among the elements that have odd atomic numbers, after hydrogen and nitrogen. The only stable isotope of aluminium, Al,

6512-416: Is quite soft and lacking in strength. In most applications various aluminium alloys are used instead because of their higher strength and hardness. The yield strength of pure aluminium is 7–11 MPa , while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium is ductile , with a percent elongation of 50-70%, and malleable allowing it to be easily drawn and extruded . It
6688-422: Is surrounded by six fluorine atoms in a distorted octahedral arrangement, with each fluorine atom being shared between the corners of two octahedra. Such {AlF 6 } units also exist in complex fluorides such as cryolite , Na 3 AlF 6 . AlF 3 melts at 1,290 °C (2,354 °F) and is made by reaction of aluminium oxide with hydrogen fluoride gas at 700 °C (1,300 °F). With heavier halides,
6864-547: Is termed amphoterism and is characteristic of weakly basic cations that form insoluble hydroxides and whose hydrated species can also donate their protons. One effect of this is that aluminium salts with weak acids are hydrolyzed in water to the aquated hydroxide and the corresponding nonmetal hydride: for example, aluminium sulfide yields hydrogen sulfide . However, some salts like aluminium carbonate exist in aqueous solution but are unstable as such; and only incomplete hydrolysis takes place for salts with strong acids, such as

Hence, the inner electrons of aluminium shield the valence electrons almost completely, unlike those of aluminium's heavier congeners. As such, aluminium is the most electropositive metal in its group, and its hydroxide

French explorers claimed lands in the Americas, paving expansion of the French colonial empire . The rise of Protestantism led France to a civil war known as the French Wars of Religion . This forced Huguenots to flee to Protestant regions such as
12848-431: The twelfth-most common element in the universe. The radioactivity of Al leads to it being used in radiometric dating . Chemically, aluminium is a post-transition metal in the boron group ; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state . The aluminium cation Al is small and highly charged ; as such, it has more polarizing power , and bonds formed by aluminium have
13024-513: The 1970s France faced an economic crisis and allowed new immigrants (mostly from the Maghreb , in northwest Africa) to permanently settle in France with their families and acquire citizenship. It resulted in hundreds of thousands of Muslims living in subsidised public housing and suffering from high unemployment rates. The government had a policy of assimilation of immigrants, where they were expected to adhere to French values and norms. Since
13200-617: The 200 years of the Crusades, in such a fashion that the Arabs referred to crusaders as Franj . French Crusaders imported French into the Levant , making Old French the base of the lingua franca ("Frankish language") of the Crusader states . The Albigensian Crusade was launched in 1209 to eliminate the heretical Cathars in the southwest of modern-day France. From the 11th century,
13376-674: The 4th century, a period of revival and prosperity. In 312, Emperor Constantine I converted to Christianity . Christians, who had been persecuted, increased. But from the 5th century, the Barbarian Invasions resumed. Teutonic tribes invaded the region, the Visigoths settling in the southwest, the Burgundians along the Rhine River Valley, and the Franks in the north. In Late antiquity , ancient Gaul
13552-526: The 5th century BCE. The ancients are known to have used alum as a dyeing mordant and for city defense. After the Crusades , alum, an indispensable good in the European fabric industry, was a subject of international commerce; it was imported to Europe from the eastern Mediterranean until the mid-15th century. The nature of alum remained unknown. Around 1530, Swiss physician Paracelsus suggested alum
13728-839: The Alps on the France–Italy border , is the highest point in Western Europe. Although 60% of municipalities are classified as having seismic risks (though moderate). The coastlines offer contrasting landscapes: mountain ranges along the French Riviera , coastal cliffs such as the Côte d'Albâtre , and wide sandy plains in the Languedoc . Corsica lies off the Mediterranean coast. France has an extensive river system consisting of
13904-472: The Al–Zn–Mg class. Aluminium has a high chemical affinity to oxygen, which renders it suitable for use as a reducing agent in the thermite reaction. A fine powder of aluminium reacts explosively on contact with liquid oxygen ; under normal conditions, however, aluminium forms a thin oxide layer (~5 nm at room temperature) that protects the metal from further corrosion by oxygen, water, or dilute acid,
14080-573: The Atlantic Ocean. Other water courses drain towards the Meuse and Rhine along the northeastern borders. France has 11,000,000 km (4,200,000 sq mi) of marine waters within three oceans under its jurisdiction, of which 97% are overseas. France was one of the first countries to create an environment ministry, in 1971. France is ranked 19th by carbon dioxide emissions due to the country's heavy investment in nuclear power following
14256-491: The Blickensderfer 6, which was cast in aluminium and was essentially a lighter version of the Blickensderfer 5 which used cast iron. The aluminium version also appeared as the Blickensderfer Featherweight, which was an improved Model 6 with a backspace mechanism and the ink arm support was modified to an attractive curved folding design. These typewriters weighed only 5 pounds and were widely marketed as
14432-407: The Blickensderfer Featherweight. Only about 10,000 machines were produced, ending in 1919. On August 4, 1891, after several prototypes, Blickensderfer patented The Blickensderfer Type Writing Machine. The central component was the use of the cylindrical shaped interchangeable type element which he initially patented on July 15, 1890. An earlier variation to Blickensderfer's typewheel was introduced on
14608-487: The Blickensderfer typewriter was the scientific or DHIATENSOR keyboard. The DHIATENSOR layout is shown below (with alphanumeric characters only): Blickensderfer analyzed the English language and proposed a unique and more efficient keyboard based on his research. He determined that the ten most frequently used letters were A, D, E, H, I, N, O, R, S, and T, and were used in about 70% of written text and in about 85% of all words. The middle row contained letters that occurred 24% of
14784-636: The Christian Gallo-Roman culture , and ancient Gaul was renamed Francia ("Land of the Franks"). The Germanic Franks adopted Romanic languages . Clovis made Paris his capital and established the Merovingian dynasty , but his kingdom would not survive his death. The Franks treated land as a private possession and divided it among their heirs, so four kingdoms emerged from that of Clovis: Paris, Orléans , Soissons , and Rheims . The last Merovingian kings lost power to their mayors of
14960-476: The Five-Pound Secretary. The Model 7, first introduced in 1897, became the deluxe version of the basic No. 5 and was designed to please a greater cross section of the market. The biggest and most obvious difference was the wraparound space bar, which gave the machine a more solid and distinctive look. Blickensderfer also improved the paper scale, added black composite carriage knobs at both ends of
15136-526: The Franks is related to the English word frank ("free"): the latter stems from the Old French franc ("free, noble, sincere"), and ultimately from the Medieval Latin word francus ("free, exempt from service; freeman, Frank"), a generalisation of the tribal name that emerged as a Late Latin borrowing of the reconstructed Frankish endonym * Frank . It has been suggested that
15312-476: The Franks". Later kings expanded their directly possessed domaine royal to cover over half of modern France by the 15th century. Royal authority became more assertive, centred on a hierarchically conceived society distinguishing nobility , clergy, and commoners . The nobility played a prominent role in Crusades to restore Christian access to the Holy Land . French knights made up most reinforcements in
15488-473: The French government's longtime historical association with the Catholic Church , Charlemagne tried to revive the Western Roman Empire and its cultural grandeur. Charlemagne's son, Louis I kept the empire united, however in 843, it was divided between Louis' three sons, into East Francia , Middle Francia and West Francia . West Francia approximated the area occupied by modern France and
15664-457: The Oriental, were adapted so the carriage moved from left to right, to accommodate Hebrew and Arabic languages. The company's European business declined with the onset of World War I, and production and sales were particularly hard hit when the United States joined the war in 1917. As part of the war effort Blickensderfer converted much of his factory to produce munitions for the war, including
15840-701: The Pyrenees and the Alps and the Jura, respectively, and to the east, the Rhine river. Metropolitan France includes various coastal islands, of which the largest is Corsica . Metropolitan France is situated mostly between latitudes 41° and 51° N , and longitudes 6° W and 10° E , on the western edge of Europe, and thus lies within the northern temperate zone. Its continental part covers about 1000 km from north to south and from east to west. Metropolitan France covers 551,500 square kilometres (212,935 sq mi),
16016-529: The Revolution. Some of the Enlightenment occurred in French intellectual circles, and scientific breakthroughs, such as the naming of oxygen (1778) and the first hot air balloon carrying passengers (1783), were achieved by French scientists. French explorers took part in the voyages of scientific exploration through maritime expeditions. Enlightenment philosophy, in which reason is advocated as
16192-618: The Romans in the Battle of the Allia , and besieged and ransomed Rome. This left Rome weakened, and the Gauls continued to harass the region until 345 BC when they entered into a peace treaty. But the Romans and the Gauls remained adversaries for centuries. Around 125 BC, the south of Gaul was conquered by the Romans, who called this region Provincia Nostra ("Our Province"), which evolved into Provence in French. Julius Caesar conquered
16368-418: The United States dollar, and alumina prices. The BRIC countries' combined share in primary production and primary consumption grew substantially in the first decade of the 21st century. China is accumulating an especially large share of the world's production thanks to an abundance of resources, cheap energy, and governmental stimuli; it also increased its consumption share from 2% in 1972 to 40% in 2010. In
16544-514: The United States, Western Europe, and Japan, most aluminium was consumed in transportation, engineering, construction, and packaging. In 2021, prices for industrial metals such as aluminium have soared to near-record levels as energy shortages in China drive up costs for electricity. The names aluminium and aluminum are derived from the word alumine , an obsolete term for alumina , the primary naturally occurring oxide of aluminium . Alumine
16720-578: The aluminium atoms have tetrahedral four-coordination and the other half have trigonal bipyramidal five-coordination. Four pnictides – aluminium nitride (AlN), aluminium phosphide (AlP), aluminium arsenide (AlAs), and aluminium antimonide (AlSb) – are known. They are all III-V semiconductors isoelectronic to silicon and germanium , all of which but AlN have the zinc blende structure. All four can be made by high-temperature (and possibly high-pressure) direct reaction of their component elements. Aluminium alloys well with most other metals (with
16896-711: The area in 51 BC, leading to a distinct Gallo-Roman culture . In the Early Middle Ages , the Franks formed the Kingdom of Francia , which became the heartland of the Carolingian Empire . The Treaty of Verdun of 843 partitioned the empire, with West Francia evolving into the Kingdom of France . In the High Middle Ages , France was a powerful but decentralized feudal kingdom, but from
17072-508: The bankrupt L.R. Roberts Company in 1926. Remington attempted to introduce a modified Blickensderfer 5 called the Rem-Blick to the market, but by the end of 1928 the model was discontinued. The Blickensderfer typewriter dramatically reduced the complexity of the typewriter design. A typical Blickensderfer contained only 250 parts, compared to the 2,500 parts of a standard typewriter. It was much smaller, lighter and cheaper than others. Some of
17248-436: The characteristic physical properties of a post-transition metal, with longer-than-expected interatomic distances. Furthermore, as Al is a small and highly charged cation, it is strongly polarizing and bonding in aluminium compounds tends towards covalency ; this behavior is similar to that of beryllium (Be ), and the two display an example of a diagonal relationship . The underlying core under aluminium's valence shell
17424-514: The climate became milder; from approximately 7,000 BC, this part of Western Europe entered the Neolithic era, and its inhabitants became sedentary . After demographic and agricultural development between the 4th and 3rd millennia BC, metallurgy appeared , initially working gold, copper and bronze , then later iron . France has numerous megalithic sites from the Neolithic, including
17600-489: The company became one of the world's largest typewriter manufacturers." The factory employed about 200 people and produced about 10,000 typewriters per year at its peak (1903-1907) until the factory closed in 1919. The first commercially successful model was the No. 5, which sold for $ 35, compared to the benchmark machines of the day which cost $ 100 or more. Each new Model 5 came in a simple wooden carrying case with an extra typewheel,
17776-822: The constitutional July Monarchy ; French troops began the conquest of Algeria . Unrest led to the French Revolution of 1848 and the end of the July Monarchy. The abolition of slavery and introduction of male universal suffrage was re-enacted in 1848. In 1852, president of the French Republic, Louis-Napoléon Bonaparte , Napoleon I's nephew, was proclaimed emperor of the Second Empire , as Napoleon III. He multiplied French interventions abroad, especially in Crimea , Mexico and Italy . Napoleon III
17952-419: The coordination numbers are lower. The other trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium centers. Aluminium trichloride (AlCl 3 ) has a layered polymeric structure below its melting point of 192.4 °C (378 °F) but transforms on melting to Al 2 Cl 6 dimers. At higher temperatures those increasingly dissociate into trigonal planar AlCl 3 monomers similar to
18128-428: The core. In the Earth's crust, aluminium is the most abundant metallic element (8.23% by mass ) and the third most abundant of all elements (after oxygen and silicon). A large number of silicates in the Earth's crust contain aluminium. In contrast, the Earth's mantle is only 2.38% aluminium by mass. Aluminium also occurs in seawater at a concentration of 2 μg/kg. Because of its strong affinity for oxygen, aluminium
18304-498: The course of the defeat in the Algerian War . The current Fifth Republic was formed in 1958 by Charles de Gaulle . Algeria and most French colonies became independent in the 1960s, with the majority retaining close economic and military ties with France . France retains its centuries-long status as a global centre of art , science , and philosophy . It hosts the fourth-largest number of UNESCO World Heritage Sites and
18480-526: The empire, leaving England and Aquitaine to the Plantagenets. Charles IV the Fair died without an heir in 1328. The crown passed to Philip of Valois , rather than Edward of Plantagenet, who became Edward III of England . During the reign of Philip, the monarchy reached the height of its medieval power. However Philip's seat on the throne was contested by Edward in 1337, and England and France entered
18656-542: The end of the company's existence, most machines were sold with the universal keyboard. There were modifications to the layout made for Spanish , French , German , and Polish . By way of comparison, the later Dvorak keyboard layout has the consonants on its home row in DHIATENSOR order: D H T N S . The Dvorak R is in the neighboring far row, between T and N . The same vowels, plus U , are present on
18832-497: The energy released by the decay of Al was responsible for the melting and differentiation of some asteroids after their formation 4.55 billion years ago. The remaining isotopes of aluminium, with mass numbers ranging from 21 to 43, all have half-lives well under an hour. Three metastable states are known, all with half-lives under a minute. An aluminium atom has 13 electrons, arranged in an electron configuration of [ Ne ] 3s 3p , with three electrons beyond
19008-613: The ensuing uprising of European monarchies against his rule, Napoleon was defeated. About a million Frenchmen died during the Napoleonic Wars . After his brief return from exile, Napoleon was finally defeated in 1815 at the Battle of Waterloo , and the Bourbon monarchy was restored with new constitutional limitations. The discredited Bourbon dynasty was overthrown by the July Revolution of 1830, which established
19184-478: The exception of most alkali metals and group 13 metals) and over 150 intermetallics with other metals are known. Preparation involves heating fixed metals together in certain proportion, followed by gradual cooling and annealing . Bonding in them is predominantly metallic and the crystal structure primarily depends on efficiency of packing. There are few compounds with lower oxidation states. A few aluminium(I) compounds exist: AlF, AlCl, AlBr, and AlI exist in
19360-520: The fact that its nuclei are much lighter, while difference in the unit cell size does not compensate for this difference. The only lighter metals are the metals of groups 1 and 2 , which apart from beryllium and magnesium are too reactive for structural use (and beryllium is very toxic). Aluminium is not as strong or stiff as steel, but the low density makes up for this in the aerospace industry and for many other applications where light weight and relatively high strength are crucial. Pure aluminium
19536-483: The first aluminium typewriters, marketed as the Blickensderfer 6 and the Blickensderfer Featherweight, were made by Blickensderfer, as was the world's first fully electric typewriter , the Blickensderfer Electric. Instead of the common mechanism with letters on the end of individual type bars connected to the keys, the first Blickensderfer prototype used a cylindrical typewheel with four rows of characters; lower case, upper case, italics and short words embossed on it. It
19712-594: The forefront of the development of a supranational European Union , notably by signing the Maastricht Treaty in 1992, establishing the eurozone in 1999 and signing the Treaty of Lisbon in 2007. France has fully reintegrated into NATO and since participated in most NATO-sponsored wars. Since the 19th century, France has received many immigrants , often male foreign workers from European Catholic countries who generally returned home when not employed. During
19888-861: The four major rivers Seine , the Loire , the Garonne , the Rhône and their tributaries, whose combined catchment includes over 62% of the metropolitan territory. The Rhône divides the Massif Central from the Alps and flows into the Mediterranean Sea at the Camargue . The Garonne meets the Dordogne just after Bordeaux, forming the Gironde estuary , the largest estuary in Western Europe which after approximately 100 kilometres (62 mi) empties into
20064-730: The gas phase after explosion and in stellar absorption spectra. More thoroughly investigated are compounds of the formula R 4 Al 2 which contain an Al–Al bond and where R is a large organic ligand . A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them. They often form dimers, unlike their boron analogues, but this tendency diminishes for branched-chain alkyls (e.g. Pr , Bu , Me 3 CCH 2 ); for example, triisobutylaluminium exists as an equilibrium mixture of
20240-453: The gaseous phase when the respective trihalide is heated with aluminium, and at cryogenic temperatures. A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine , Al 4 I 4 (NEt 3 ) 4 . Al 2 O and Al 2 S also exist but are very unstable. Very simple aluminium(II) compounds are invoked or observed in the reactions of Al metal with oxidants. For example, aluminium monoxide , AlO, has been detected in
20416-646: The halides, nitrate , and sulfate . For similar reasons, anhydrous aluminium salts cannot be made by heating their "hydrates": hydrated aluminium chloride is in fact not AlCl 3 ·6H 2 O but [Al(H 2 O) 6 ]Cl 3 , and the Al–O bonds are so strong that heating is not sufficient to break them and form Al–Cl bonds instead: All four trihalides are well known. Unlike the structures of the three heavier trihalides, aluminium fluoride (AlF 3 ) features six-coordinate aluminium, which explains its involatility and insolubility as well as high heat of formation . Each aluminium atom
20592-492: The ink roller to strike the paper. Holding the Cap or Fig keys shifted the typewheel along its axis to use either the middle row, for capital letters, or the lower row, for special characters and numbers. Industrial production in the 1890s was not highly automated and assembly was done completely by hand. This allowed for easy design changes and improvements to the production process. Blickensderfer continued to improve his machines and
20768-481: The keys striking each other and jamming was more limited with this configuration. Because the Blickensderfer used the typewheel, the "scientific" keyboard layout could be used for maximum typing efficiency. The first widely successful production model was the Blickensderfer 5, introduced at the 1893 World's Columbian Exposition in Chicago. Production of the model 5 did not seriously get underway until 1895-1896. The 5
20944-479: The largest among European Union members. France's total land area, with its overseas departments and territories (excluding Adélie Land ), is 643,801 km (248,573 sq mi), 0.45% of the total land area on Earth. France possesses a wide variety of landscapes, from coastal plains in the north and west to mountain ranges of the Alps in the southeast, the Massif Central in the south-central and Pyrenees in
21120-630: The left in a different order. Another machine that had its keys arranged in a 'scientific' order, although not designed for home use, was the Linotype machine , with the first two columns of the lower-case and caps key sections arranged in ETAOIN SHRDLU order. Aluminium Aluminium (or aluminum in North American English ) is a chemical element ; it has symbol Al and atomic number 13. Aluminium has
21296-433: The low-pressure polymerization of ethene and propene . There are also some heterocyclic and cluster organoaluminium compounds involving Al–N bonds. The industrially most important aluminium hydride is lithium aluminium hydride (LiAlH 4 ), which is used as a reducing agent in organic chemistry . It can be produced from lithium hydride and aluminium trichloride . The simplest hydride, aluminium hydride or alane,
21472-472: The machine, making it easy to operate. Production peaked in 1910 and declined until production ended in 1917. About 20,000 Blickensderfer 8's were produced, accounting for about 10% of all Blickensderfer models sold. The Model 9, believed to be introduced in mid-1910, was similar in appearance to the Model 8, but lacked the nickel plated tabulator keys and also featured a folding ink roller arm support similar to
21648-466: The meaning "free" was adopted because, after the conquest of Gaul , only Franks were free of taxation, or more generally because they had the status of freemen in contrast to servants or slaves. The etymology of *Frank is uncertain. It is traditionally derived from the Proto-Germanic word * frankōn , which translates as "javelin" or "lance" (the throwing axe of the Franks was known as
21824-529: The metal remained rare; its cost exceeded that of gold. The first industrial production of aluminium was established in 1856 by French chemist Henri Etienne Sainte-Claire Deville and companions. Deville had discovered that aluminium trichloride could be reduced by sodium, which was more convenient and less expensive than potassium, which Wöhler had used. Even then, aluminium was still not of great purity and produced aluminium differed in properties by sample. Because of its electricity-conducting capacity, aluminium
22000-600: The metal to be isolated from alum was alumium , which Davy suggested in an 1808 article on his electrochemical research, published in Philosophical Transactions of the Royal Society . It appeared that the name was created from the English word alum and the Latin suffix -ium ; but it was customary then to give elements names originating in Latin, so this name was not adopted universally. This name
22176-465: The metal with many uses at the time. During World War I , major governments demanded large shipments of aluminium for light strong airframes; during World War II , demand by major governments for aviation was even higher. By the mid-20th century, aluminium had become a part of everyday life and an essential component of housewares. In 1954, production of aluminium surpassed that of copper , historically second in production only to iron, making it
22352-491: The metal. Almost all metallic aluminium is produced from the ore bauxite (AlO x (OH) 3–2 x ). Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions. In 2017, most bauxite was mined in Australia, China, Guinea, and India. The history of aluminium has been shaped by usage of alum . The first written record of alum, made by Greek historian Herodotus , dates back to
22528-542: The mid-14th to the mid-15th centuries, France was plunged into a dynastic conflict with England known as the Hundred Years' War . In the 16th century, the French Renaissance saw culture flourish and a French colonial empire rise. Internally, France was dominated by the conflict with the House of Habsburg and the French Wars of Religion between Catholics and Huguenots . France was successful in
22704-485: The monomer and dimer. These dimers, such as trimethylaluminium (Al 2 Me 6 ), usually feature tetrahedral Al centers formed by dimerization with some alkyl group bridging between both aluminium atoms. They are hard acids and react readily with ligands, forming adducts. In industry, they are mostly used in alkene insertion reactions, as discovered by Karl Ziegler , most importantly in "growth reactions" that form long-chain unbranched primary alkenes and alcohols, and in
22880-506: The most produced non-ferrous metal . During the mid-20th century, aluminium emerged as a civil engineering material, with building applications in both basic construction and interior finish work, and increasingly being used in military engineering, for both airplanes and land armor vehicle engines. Earth's first artificial satellite , launched in 1957, consisted of two separate aluminium semi-spheres joined and all subsequent space vehicles have used aluminium to some extent. The aluminium can
23056-591: The most-used language in diplomacy, science, and literature until the 20th century. France took control of territories in the Americas, Africa and Asia. In 1685, Louis XIV revoked the Edict of Nantes , forcing thousands of Huguenots into exile and published the Code Noir providing the legal framework for slavery and expelling Jews from French colonies. Under the wars of Louis XV (r. 1715–1774), France lost New France and most Indian possessions after its defeat in
23232-458: The newly established kingdoms. These victories led to the worldwide expansion of French revolutionary ideals and reforms, such as the metric system , Napoleonic Code and Declaration of the Rights of Man. In 1812 Napoleon attacked Russia , reaching Moscow. Thereafter his army disintegrated through supply problems, disease, Russian attacks, and finally winter. After this catastrophic campaign and
23408-614: The next decade, the -um spelling dominated American usage. In 1925, the American Chemical Society adopted this spelling. The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990. In 1993, they recognized aluminum as an acceptable variant; the most recent 2005 edition of the IUPAC nomenclature of inorganic chemistry also acknowledges this spelling. IUPAC official publications use
23584-507: The off-and-on Hundred Years' War . Boundaries changed, but landholdings inside France by English Kings remained extensive for decades. With charismatic leaders, such as Joan of Arc , French counterattacks won back most English continental territories. France was struck by the Black Death , from which half of the 17 million population died. The French Renaissance saw cultural development and standardisation of French, which became
23760-507: The only one that has existed on Earth in its current form since the formation of the planet. It is therefore a mononuclidic element and its standard atomic weight is virtually the same as that of the isotope. This makes aluminium very useful in nuclear magnetic resonance (NMR), as its single stable isotope has a high NMR sensitivity. The standard atomic weight of aluminium is low in comparison with many other metals. All other isotopes of aluminium are radioactive . The most stable of these
23936-407: The oxidation state 3+. The coordination number of such compounds varies, but generally Al is either six- or four-coordinate. Almost all compounds of aluminium(III) are colorless. In aqueous solution, Al exists as the hexaaqua cation [Al(H 2 O) 6 ] , which has an approximate K a of 10 . Such solutions are acidic as this cation can act as a proton donor and progressively hydrolyze until
24112-631: The palace (head of household). One mayor of the palace, Charles Martel , defeated an Umayyad invasion of Gaul at the Battle of Tours (732). His son, Pepin the Short , seized the crown of Francia from the weakened Merovingians and founded the Carolingian dynasty . Pepin's son, Charlemagne , reunited the Frankish kingdoms and built an empire across Western and Central Europe . Proclaimed Holy Roman Emperor by Pope Leo III and thus establishing
24288-405: The palten, added adjustable margin stops and a bell mechanism designed to be struck by a clapper attached to the inker arm indicating when the carriage was approaching the end of the typed line. The Blickensderfer 7 was also mounted on an oak base fitted with an attractive bentwood laminated oak case. About 63,000 Blickensderfer No. 7's were produced from 1897 until 1916. The Blickensderfer Electric
24464-460: The patents he filed between 1886 and 1903. It is unknown whether this spelling was introduced by mistake or intentionally, but Hall preferred aluminum since its introduction because it resembled platinum , the name of a prestigious metal. By 1890, both spellings had been common in the United States, the -ium spelling being slightly more common; by 1895, the situation had reversed; by 1900, aluminum had become twice as common as aluminium ; in
24640-572: The primary source of legitimacy , undermined the power of and support for the monarchy and was a factor in the Revolution. The French Revolution was a period of political and societal change that began with the Estates General of 1789 , and ended with the coup of 18 Brumaire in 1799 and the formation of the French Consulate . Many of its ideas are fundamental principles of liberal democracy , while its values and institutions remain central to modern political discourse. Its causes were
24816-534: The remainder of Gaul and overcame a revolt by Gallic chieftain Vercingetorix in 52 BC. Gaul was divided by Augustus into provinces and many cities were founded during the Gallo-Roman period , including Lugdunum (present-day Lyon ), the capital of the Gauls. In 250–290 AD, Roman Gaul suffered a crisis with its fortified borders attacked by barbarians . The situation improved in the first half of
24992-423: The respective hydrogen chalcogenide . As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite , with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual high-temperature hexagonal form where half
25168-399: The revolt was a political failure (the Gaullist party emerged stronger than before) it announced a split between the French and de Gaulle, who resigned. In the post-Gaullist era, France remained one of the most developed economies in the world but faced crises that resulted in high unemployment rates and increasing public debt. In the late 20th and early 21st centuries, France has been at
25344-485: The scale of the economies. However, the need to exploit lower-grade poorer quality deposits and the use of fast increasing input costs (above all, energy) increased the net cost of aluminium; the real price began to grow in the 1970s with the rise of energy cost. Production moved from the industrialized countries to countries where production was cheaper. Production costs in the late 20th century changed because of advances in technology, lower energy prices, exchange rates of
25520-436: The second-largest behind the British Empire . Including metropolitan France, the total area reached almost 13 million square kilometres in the 1920s and 1930s, 9% of the world's land. Known as the Belle Époque , the turn of the century was characterised by optimism, regional peace, economic prosperity and technological, scientific and cultural innovations. In 1905, state secularism was officially established . France
25696-421: The southwest. Due to its numerous overseas departments and territories scattered across the planet, France possesses the second-largest exclusive economic zone (EEZ) in the world, covering 11,035,000 km (4,261,000 sq mi). Its EEZ covers approximately 8% of the total surface of all the EEZs of the world. Metropolitan France has a wide variety of topographical sets and natural landscapes. During
25872-488: The state and reinforced royal power. He destroyed castles of defiant lords and denounced the use of private armies. By the end of the 1620s, Richelieu established "the royal monopoly of force". France fought in the Thirty Years' War , supporting the Protestant side against the Habsburgs. From the 16th to the 19th century, France was responsible for about 10% of the transatlantic slave trade . During Louis XIV 's minority, trouble known as The Fronde occurred. This rebellion
26048-408: The structure of BCl 3 . Aluminium tribromide and aluminium triiodide form Al 2 X 6 dimers in all three phases and hence do not show such significant changes of properties upon phase change. These materials are prepared by treating aluminium with the halogen. The aluminium trihalides form many addition compounds or complexes; their Lewis acidic nature makes them useful as catalysts for
26224-447: The time and the top row about 6%. Blickensderfer offered the scientific keyboard in the hopes that his more efficient system would replace the clumsy but widely used QWERTY or universal keyboard developed by Sholes and Glidden in 1874. Unfortunately for Blickensderfer, no other typewriter manufacturer adopted the scientific keyboard and Blickensderfer had no choice but to offer the universal keyboard on all his machines as an option. Toward
26400-514: The time many homes and businesses were not wired for electricity. Electricity was primarily used for lighting and therefore not widely available during the daytime. The Blickensderfer Electrics were advertised and marketed in both France and Britain, although it is not known how many machines were ultimately sold. Very few machines are known to exist today, and they are found with both straight fronts and QWERTY keyboards or curved fronts and DHIATENSOR keyboards. The Blickensderfer 8 introduced in 1908
26576-536: The two therefore look similar. Aluminium is also good at reflecting solar radiation , although prolonged exposure to sunlight in air adds wear to the surface of the metal; this may be prevented if aluminium is anodized , which adds a protective layer of oxide on the surface. The density of aluminium is 2.70 g/cm , about 1/3 that of steel, much lower than other commonly encountered metals, making aluminium parts easily identifiable through their lightness. Aluminium's low density compared to most other metals arises from
26752-424: The unoccupied territory. Free France , the government-in-exile led by Charles de Gaulle , was set up in London. From 1942 to 1944, about 160,000 French citizens, including around 75,000 Jews , were deported to death and concentration camps . On 6 June 1944, the Allies invaded Normandy , and in August they invaded Provence . The Allies and French Resistance emerged victorious, and French sovereignty
26928-423: The world . Metropolitan France shares borders with Belgium and Luxembourg to the north, Germany to the northeast, Switzerland to the east, Italy and Monaco to the southeast, Andorra and Spain to the south, and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and
27104-401: Was invaded by Germany and defended by Great Britain at the start of World War I in August 1914. A rich industrial area in the north was occupied. France and the Allies emerged victorious against the Central Powers at tremendous human cost. It left 1.4 million French soldiers dead, 4% of its population. Interwar was marked by intense international tensions and social reforms introduced by
27280-410: Was a founding member of NATO and attempted to regain control of French Indochina , but was defeated by the Viet Minh in 1954. France faced another anti-colonialist conflict in Algeria , then part of France and home to over one million European settlers ( Pied-Noir ). The French systematically used torture and repression, including extrajudicial killings to keep control. This conflict nearly led to
27456-450: Was a revolutionary machine and was far ahead of its time when it was first introduced at the Pan-American Exhibition in Buffalo in 1901 following its patent in August 1900 (patent no.656,085). It had all the familiar characteristics of the manual models, plus a QWERTY or a DHIATENSOR keyboard and all the advantages of later electric typewriters, including a light key touch, even typing, and automatic carriage return and line spacing. The machine
27632-461: Was a salt of an earth of alum. In 1595, German doctor and chemist Andreas Libavius experimentally confirmed this. In 1722, German chemist Friedrich Hoffmann announced his belief that the base of alum was a distinct earth. In 1754, German chemist Andreas Sigismund Marggraf synthesized alumina by boiling clay in sulfuric acid and subsequently adding potash . Attempts to produce aluminium date back to 1760. The first successful attempt, however,
27808-480: Was announced in 1825 by Danish physicist Hans Christian Ørsted . The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life. In
27984-424: Was borrowed from French, which in turn derived it from alumen , the classical Latin name for alum , the mineral from which it was collected. The Latin word alumen stems from the Proto-Indo-European root *alu- meaning "bitter" or "beer". British chemist Humphry Davy , who performed a number of experiments aimed to isolate the metal, is credited as the person who named the element. The first name proposed for
28160-422: Was completed in 1824 by Danish physicist and chemist Hans Christian Ørsted . He reacted anhydrous aluminium chloride with potassium amalgam , yielding a lump of metal looking similar to tin. He presented his results and demonstrated a sample of the new metal in 1825. In 1827, German chemist Friedrich Wöhler repeated Ørsted's experiments but did not identify any aluminium. (The reason for this inconsistency
28336-443: Was criticized by contemporary chemists from France, Germany, and Sweden, who insisted the metal should be named for the oxide, alumina, from which it would be isolated. The English name alum does not come directly from Latin, whereas alumine / alumina obviously comes from the Latin word alumen (upon declension , alumen changes to alumin- ). One example was Essai sur la Nomenclature chimique (July 1811), written in French by
28512-451: Was divided into Germanic kingdoms and a remaining Gallo-Roman territory. Celtic Britons , fleeing the Anglo-Saxon settlement of Britain , settled in west Armorica ; the Armorican peninsula was renamed Brittany and Celtic culture was revived. The first leader to unite all Franks was Clovis I , who began his reign as king of the Salian Franks in 481, routing the last forces of the Roman governors in 486. Clovis said he would be baptised
28688-479: Was driven by feudal lords and sovereign courts as a reaction to the royal absolute power . The monarchy reached its peak during the 17th century and reign of Louis XIV. By turning lords into courtiers at the Palace of Versailles , his command of the military went unchallenged. The "Sun King" made France the leading European power. France became the most populous European country and had tremendous influence over European politics, economy, and culture. French became
28864-405: Was executed in January 1793. After another revolt in June 1793 , the constitution was suspended and power passed from the National Convention to the Committee of Public Safety . About 16,000 people were executed in a Reign of Terror , which ended in July 1794 . Weakened by external threats and internal opposition, the Republic was replaced in 1795 by the Directory . Four years later in 1799,
29040-418: Was invented in 1956 and employed as a storage for drinks in 1958. Throughout the 20th century, the production of aluminium rose rapidly: while the world production of aluminium in 1900 was 6,800 metric tons, the annual production first exceeded 100,000 metric tons in 1916; 1,000,000 tons in 1941; 10,000,000 tons in 1971. In the 1970s, the increased demand for aluminium made it an exchange commodity; it entered
29216-414: Was its precursor. During the 9th and 10th centuries, threatened by Viking invasions , France became a decentralised state: the nobility's titles and lands became hereditary, and authority of the king became more religious than secular, and so was less effective and challenged by noblemen. Thus was established feudalism in France. Some king's vassals grew so powerful they posed a threat to the king. After
29392-435: Was later modified to three rows of characters: lower case, upper case and a row of numbers and symbols. Depressing a key caused the typewheel to turn so the correct letter was positioned over the paper. As the wheel turned it moved downward, contacting an ink roller prior to striking the paper. This allowed for greater speed in typing as there were no keys to become jammed or stuck together. The interchangeable typewheel principle
29568-433: Was only discovered in 1921.) He conducted a similar experiment in the same year by mixing anhydrous aluminium chloride with potassium and produced a powder of aluminium. In 1845, he was able to produce small pieces of the metal and described some physical properties of this metal. For many years thereafter, Wöhler was credited as the discoverer of aluminium. As Wöhler's method could not yield great quantities of aluminium,
29744-414: Was powered by an Emerson electric motor mounted on the rear and switched on by turning a Yale key on the side. The motor ran on 104 Volt 60 Hz AC electric current, which was not yet widely standard at the time. (See War of the currents ) It is believed that the Blickensderfer Electric was produced from 1901 to 1919. Although a technological and engineering success, it was a commercial failure as at
29920-453: Was restored with the Provisional Government of the French Republic (GPRF). This interim government, established by de Gaulle, continued to wage war against Germany and to purge collaborators from office . It made important reforms e.g. suffrage extended to women and the creation of a social security system. A new constitution resulted in the Fourth Republic (1946–1958), which saw strong economic growth ( les Trente Glorieuses ). France
30096-608: Was set to impose a carbon tax in 2009; however, the plan was abandoned due to fears of burdening French businesses. Forests account for 31 per cent of France's land area—the fourth-highest proportion in Europe—representing an increase of 7 per cent since 1990. French forests are some of the most diverse in Europe, comprising more than 140 species of trees. France had a 2018 Forest Landscape Integrity Index mean score of 4.52/10, ranking it 123rd globally. There are nine national parks and 46 natural parks in France. A regional nature park (French: parc naturel régional or PNR)
30272-420: Was the central component of all the Blickensderfer machines. It could be easily removed, allowing users to select a large variety of fonts and typefaces. Later in the company’s production history, the basic machines' keyboards could easily be adapted to other languages at the Blickensderfer factory simply by changing the removable keytop covers and adding the corresponding language typewheel. One unique feature of
30448-409: Was the first Blickensderfer to boast a tabulator system (see Tab stop ), even though tabulators had been around for some time. This model was a considerable success and more were sold in 1908 than any other model. This machine was more massive and sturdier looking than the 7 with a two-piece typehead casting and a popular backspace mechanism. The tabulator used large nickel-plated levers placed on top of
30624-566: Was the first portable, full keyboard, typewriter and came with the DHIATENSOR keyboard as standard or with a QWERTY keyboard available on request. Some of the earliest Blickensderfer 5's were sold in France as the Dactyle . The Blickensderfer 5 was the simplest of all Blickensderfer models and more were produced than any other Blickensderfer machine. About 74,000 or 37% of the 200,000 Blickensderfer typewriters produced, were No. 5's and their production continued until 1913, when other models became more popular. In 1910 George Blickensderfer introduced
30800-404: Was unseated following defeat in the Franco-Prussian War of 1870, and his regime replaced by the Third Republic . By 1875, the French conquest of Algeria was complete, with approximately 825,000 Algerians killed from famine, disease, and violence. France had colonial possessions since the beginning of the 17th century, but in the 19th and 20th centuries its empire extended greatly and became
30976-510: Was used as the cap of the Washington Monument , completed in 1885. The tallest building in the world at the time, the non-corroding metal cap was intended to serve as a lightning rod peak. The first industrial large-scale production method was independently developed in 1886 by French engineer Paul Héroult and American engineer Charles Martin Hall ; it is now known as the Hall–Héroult process . The Hall–Héroult process converts alumina into metal. Austrian chemist Carl Joseph Bayer discovered
