15-471: Dominion Steel Casting Company (Dofasco) established in 1912. Later named Dominion Foundries and Steel, the company merged with its subsidiary, Hamilton Steel Wheel Company in 1917. The name was officially changed to Dofasco Inc. in 1980. In 1912, National Steel Car is established in Hamilton. Builders of reliable freight and passenger train cars and equipment. Also by 1912, with 4.5 miles of dockage, Hamilton

30-486: A semantic field . A common pattern is that one sense is broader and another narrower. This is often the case in technical jargon , where the target audience uses a narrower sense of a word that a general audience would tend to take in its broader sense. For example, in casual use " orthography " will often be glossed for a lay audience as " spelling ", but in linguistic usage "orthography" (comprising spelling, casing , spacing , hyphenation , and other punctuation )

45-534: A word . For example, a dictionary may have over 50 different senses of the word " play ", each of these having a different meaning based on the context of the word's usage in a sentence , as follows: We went to see the play Romeo and Juliet at the theater. The coach devised a great play that put the visiting team on the defensive. The children went out to play in the park. In each sentence different collocates of "play" signal its different meanings. People and computers , as they read words, must use

60-720: A full day's hike. The Trail is 430 miles long and starts at Niagara Falls , passes through Hamilton and ends at the Bruce Peninsula . Hikers are led to scenic gorges , hidden waterfalls and places of quiet charm. Pier 23 is home to Lakeshore Sand, which processes foundry and glass-making sand , casting and water filtration sand, and bunker sand supplied to nearly 40 area golf courses.

75-435: A process called word-sense disambiguation to reconstruct the likely intended meaning of a word. This process uses context to narrow the possible senses down to the probable ones. The context includes such things as the ideas conveyed by adjacent words and nearby phrases, the known or probable purpose and register of the conversation or document, and the orientation (time and place) implied or expressed. The disambiguation

90-725: A set of steps made of steel nearby at the end of Kimberly Drive near Kenilworth Avenue that go from the lower city to the Escarpment Rail Trail and the Bruce Trail , and another set of stairs a few hundred feet east of those connecting the Rail Trail and the Mountain Brow at Margate Avenue. The Bruce Trail cuts through the city along the Niagara Escarpment (mountain) and used by many locals for

105-592: Is implicit within a context. Common examples are as follows: Usage labels of " sensu " plus a qualifier , such as " sensu stricto " ("in the strict sense") or " sensu lato " ("in the broad sense") are sometimes used to clarify what is meant by a text. Polysemy entails a common historic root to a word or phrase. Broad medical terms usually followed by qualifiers , such as those in relation to certain conditions or types of anatomical locations are polysemic, and older conceptual words are with few exceptions highly polysemic (and usually beyond shades of similar meaning into

120-407: Is a hypernym of "spelling". Besides jargon, however, the pattern is common even in general vocabulary. Examples are the variation in senses of the term "wood wool" and in those of the word "bean" . This pattern entails that natural language can often lack explicitness about hyponymy and hypernymy . Much more than programming languages do, it relies on context instead of explicitness; meaning

135-589: Is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance. Examples of items that are steel castings include: hydroelectric turbine wheels , forging presses , gears , railroad truck frames , valve bodies, pump casings, mining machinery , marine equipment , turbocharger turbines and engine cylinder blocks . Steel castings are categorized into two general groups: carbon steels and alloy steels . Steel

150-412: Is a table of some steel casting alloys: In present-day vocabulary, the term cast steel is almost always used in its sense referring to steel castings. Between the late 19th and mid 20th centuries, this was not always true, which is worth understanding if one is reading historical documents; see cast steel for details. Word sense In linguistics , a word sense is one of the meanings of

165-543: Is also less fluid than molten iron, making it more difficult to pour and fill intricate gaps in a mold cavity. Molten steel is also more likely to react with internal mold surfaces, making for more unpredictable results. Cast parts often require machining to achieve accurate tolerances and desired surface finishes. Carbon steel is the easiest type of steel to machine. High-carbon steel can be more time consuming to cut or grind, and will wear tools faster. Low-carbon steel can get gummy, making it difficult to work with. Generally,

180-423: Is more difficult to cast than iron. It has a higher melting point and greater shrinkage rate, which requires consideration during mold design. Risers should be given more capacity to draw from as the metal cools and shrinks. Attention should be paid to the thickness of mold cavities, as thinner areas will cool quicker than thicker areas, which can create internal stress points that can lead to fracture. Molten steel

195-435: Is second only to Montreal in shipping. Firestone Tire and Rubber Company of Canada (1919–1988) was based just east of Kenilworth Avenue North on Burlington Street with neighbouring National Steel Car on its left. Uli's Stairs are stone steps that connect the mountain brow to the Rail Trail. They were made by a local man named Ulrich, otherwise known as Uli. The city sees his steps as a risk to public safety. The city has

210-402: Is thus context-sensitive . Advanced semantic analysis has resulted in a sub-distinction. A word sense corresponds either neatly to a seme (the smallest possible unit of meaning ) or a sememe (larger unit of meaning), and polysemy of a word of phrase is the property of having multiple semes or sememes and thus multiple senses. Often the senses of a word are related to each other within

225-858: The presence of alloys used to increase mechanical performance often make machining more difficult. Casting is often a valuable means to creating intricate parts used in machine applications where vibration is often a factor. Cast steel typically has a lower damping ability than cast iron, which can lead to excess vibration and noise in the form of ringing or squealing. Most steels offer a good balance of strength and ductility, which makes them extremely tough. This allows them to withstand significant stress and strain without fracturing. Steel can also be fairly wear-resistant. Alloy additions can increase both impact and wear resistance. Alloy steel castings are broken down into two categories: low-alloy steels and high-alloy steels. Low-alloy steels contain less than 8% alloying content and high-alloy steels have 8% or more. This
