Hot Metal Typesetting
In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing. This method injects molten type metal into a mold that has the shape of one or more glyphs. The resulting sorts or slugs are later used to press ink onto paper. Normally the typecasting machine would be controlled by a keyboard or by a paper tape. It was the standard technology used for mass-market printing from the late nineteenth century until the arrival of phototypesetting and then electronic processes in the 1950s to 1980s. History Hot metal typesetting was developed in the late nineteenth century as a development of conventional cast metal type. The technology had several advantages: it reduced labour since type sorts did not need to be slotted into position manually, and each casting created crisp new type for each printing job. In the case of Linotype machines, each line was ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ludlow Typograph
A Ludlow Typograph is a hot metal typesetting system used in letterpress printing. The device casts bars, or slugs of type, out of type metal primarily consisting of lead. These slugs are used for the actual printing, and then are melted down and recycled on the spot. It was used to print large-type material such as newspaper headlines or posters. The Ludlow system uses molds, known as matrices or mats, which are hand-set into a special composing stick. Thus the composing process resembles that used in cold lead type printing. Once a line has been completed, the composing stick is inserted into the Ludlow machine, which clamps it firmly in place above the mold. Hot linecasting metal (the same alloy used in Linotype and Intertype machines) is then injected through the mold into the matrices, allowed to cool, and then the bottom of the slug is trimmed just before it is ejected. The operator then replaces the matrices, or mats, back into the typecase by hand. Since the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quads
The quadriceps femoris muscle (, also called the quadriceps extensor, quadriceps or quads) is a large muscle group that includes the four prevailing muscles on the front of the thigh. It is the sole extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur. The name derives . Structure Parts The quadriceps femoris muscle is subdivided into four separate muscles (the 'heads'), with the first superficial to the other three over the femur (from the trochanters to the condyles): *The rectus femoris muscle occupies the middle of the thigh, covering most of the other three quadriceps muscles. It originates on the ilium. It is named for its straight course. *The vastus lateralis muscle is on the ''lateral side'' of the femur (i.e. on the outer side of the thigh). *The vastus medialis muscle is on the ''medial side'' of the femur (i.e. on the inner part thigh). *The vastus intermedius muscle lies between vastus lateralis and vastus mediali ...

Backshop
A backshop or back-shop is a specialized store or workshop found in service industries, such as locomotive and aircraft repair. Most repairs are carried out in small workshops, except where an industrial service is needed. In the military, backshops repair parts are known as shop-replaceable units (SRUs). These are commonly-stocked subassemblies of a larger system, such as circuit cards components of a line-replaceable unit (LRU), designed to be repaired at the field level. Repair at this level is known as field-level maintenance or intermediate-level (I-level) maintenance. Calibration and repair of United States Air Force test equipment is conducted at shops known as precision measurement equipment laboratories. See also * Armory (military) * Back office * Railway workshop Railway workshops are railway facilities in which rolling stock is repaired. While often colocated with engine sheds to perform routine tasks as well as major repairs, in some countries separated co ...

White Gas
Coleman fuel, also generically sold as white gas, is a petroleum naphtha product marketed by the Coleman Company. Contents Historically called ''white gas'', it is a liquid petroleum fuel (100% light hydrotreated distillate), composed of cyclohexane, nonane, octane, heptane, and pentane. White gas was originally simply additive-free gasoline. This formulation is now rarely found. Coleman fuel, and its white gas copies, contain additives for inhibiting rust, ease of lighting, and fast burning. It is also cleaner than the original white gas. Use Coleman fuel is used primarily for fueling lanterns and camp stoves. It is usually sold in one-gallon cans in the United States; in Europe it is usually sold in one-litre bottles. Additionally, it is a popular fuel for fire dancing. Originally, it was simply casing-head gas or drip gas, which has similar properties. Drip gas was sold commercially at gas stations and hardware stores in North America until the early 1950s. The white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and thus the burnable component consisted of a roughly equal molecular mixture of carbon monoxide and hydrogen. Thus, coal gas was highly toxic. Other compositions contain additional calorific gases such as methane, produced by the Fischer-Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fuel and lighting was manufactured fro ...

Line Shaft
A line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century. Prior to the widespread use of electric motors small enough to be connected directly to each piece of machinery, line shafting was used to distribute power from a large central power source to machinery throughout a workshop or an industrial complex. The central power source could be a water wheel, turbine, windmill, animal power or a steam engine. Power was distributed from the shaft to the machinery by a system of belts, pulleys and gears known as ''millwork''. Operation A typical line shaft would be suspended from the ceiling of one area and would run the length of that area. One pulley on the shaft would receive the power from a parent line shaft elsewhere in the building. The other pulleys would supply power to pulleys on each individual machine or to subsequent line shafts. In manufacturing where there were a lar ...

Knight Ridder
Knight Ridder was an American media company, specializing in newspaper and Internet publishing. Until it was bought by McClatchy on June 27, 2006, it was the second largest newspaper publisher in the United States, with 32 daily newspaper brands sold. Its headquarters were located in San Jose, California. History Origins The corporate ancestors of Knight Ridder were Knight Newspapers, Inc. and Ridder Publications, Inc. The first company was founded by John S. Knight upon inheriting control of the '' Akron Beacon Journal'' from his father, Charles Landon Knight, in 1933; the second company was founded by Herman Ridder when he acquired the , a German language newspaper, in 1892. As anti-German sentiment increased in the interwar period, Ridder successfully transitioned into English language publishing by acquiring ''The Journal of Commerce'' in 1926. Both companies went public in 1969 and merged on July 11, 1974. For a brief time, the combined company was the largest newspaper p ...
