The Holley Brothers Company
Holley Performance Products is an automotive performance company based in Bowling Green, Kentucky. It was founded in 1896 in Bradford, Pennsylvania by George Holley and Earl Holley. When the company was based in Michigan it was a major producer of carburetors for many Detroit-built automobiles. Later they manufactured carburetors for both street and racing applications such as the Holley "Double Pumper" and "Dominator". Holley-style carburetors have powered every NASCAR Sprint Cup team and every NHRA Pro Stock champion until both series eventually switched to electronic fuel injection (EFI). NASCAR Sprint Cup engines still utilize a Holley throttle body and Holley EFI is the spec EFI system in NHRA Pro Stock. Holley's product range has expanded to include the aforementioned fuel injection systems, performance fuel pumps, intake manifolds, superchargers, nitrous oxide injection, performance plumbing parts, exhaust systems, engine dress–up products, ignition products, data-l ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Oldsmobile Curved Dash
__NOTOC__ The gasoline-powered Oldsmobile Model R, also known as the Curved Dash Oldsmobile, is credited as being the first mass-produced automobile, meaning that it was built on an assembly line using interchangeable parts. It was introduced by the Oldsmobile company in 1901 and produced through 1903; 425 were produced the first year, 2,500 in 1902, and over 19,000 were built in all. When General Motors assumed operations from Ransom E. Olds on November 12, 1908, GM introduced the Oldsmobile Model 20, which was the 1908 Buick Model 10 with a stretched wheelbase and minor exterior changes. It was a runabout model, could seat two passengers, and sold for US$650 ($ in dollars). While competitive, due to high volume, and priced below the US$850 two-seat Ford Model C "Doctor's Car", it was more expensive than the Western 1905 Gale Model A roadster at US$500. The Black sold for $375, and the Success for US$250. It was built as a city car for short distance driving, while the larger ...

Avco
Avco Corporation is a subsidiary of Textron which operates Textron Systems Corporation and Lycoming. History The Aviation Corporation was formed on March 2, 1929, to prevent a takeover of CAM-24 airmail service operator Embry-Riddle Company by Clement Melville Keys, who planned on buying Curtiss aircraft rather than Sherman Fairchild's. With capital from Fairchild, George Hann, the Lehman Brothers, and W. A. Harriman, the holding company began acquiring small airlines. By the end of 1929, it had acquired interests in over 90 aviation-related companies. In January 1930, the board broke off the airlines into Colonial and Universal Air Lines. Universal Air Lines name was changed to American Airways, and later merged with Colonial to form American Airlines. The company was required to divest American Airlines in 1934 due to new rules for air mail contracts. The Aviation Corporation ranked 32nd among United States corporations in the value of World War II production contracts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Waffen Und Munitionsfabriken
''Deutsche Waffen- und Munitionsfabriken Aktiengesellschaft'' (German Weapons and Munitions public limited company), known as DWM, was an arms company in Imperial Germany created in 1896 when ''Ludwig Loewe & Company'' united its weapons and ammunition production facilities within one company. In 1896 Loewe founded Deutsche Waffen- und Munitionsfabriken with a munitions plant in Karlsruhe (Baden), formerly Deutsche Metallpatronenfabrik Lorenz, and the weapons plant in Berlin. Shares that Loewe had in other gun- and ammunition plants were transferred to DWM. This included Waffenfabrik Mauser, Fabrique Nationale d'Armes de Guerre (FN) in Belgium and Waffen- und Munitionsfabrik A.G. in Budapest. The DWM was orchestrated by Isidor Loewe (1848–1910), as his brother Ludwig had died in 1886. Karl Maybach (who was part of the Maybach company) was employed by the Loewe company in 1901. Firearms DWM introduced the Pistol Parabellum ('Luger Pistol') in the early 1900s. It was worked on b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harrison Radiator Corporation
Harrison Radiator Corporation was an early manufacturer of automotive radiators and heat exchangers for crewed spacecraft and guided missiles, as well as various cooling equipment for automotive, marine, industrial, nuclear, and aerospace applications, (particularly for space suits of the first two U.S. human space flights) that became a division of General Motors in 1918. Today its business is a part of General Motors' Automotive Components Group, and is based in Lockport, Niagara County, New York. History The company was known in 1910, as the Harrison Radiator Company, by Herbert C. Harrison, an inventor and entrepreneur. Harrison's technical background in metallurgy and the "Harrison Hexagon" honeycomb radiator had advantages in design (hexagon cellular efficient heat distribution) and manufacturing so that leakages became rare. The first hand-built radiator was sold in 1911 to the Remington Standard Motor Company of New York. In 1916 the company was sold to William C. Durant ...

Gray Iron
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite.. It is the most common cast iron and the most widely used cast material based on weight.. It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings. Grey cast iron's high thermal conductivity and specific heat capacity are often exploited to make cast iron cookware and disc brake rotors. Its former widespread use on brakes in freight trains has been greatly reduced in the European Union over concerns regarding noise pollution. Deutsche Bahn for example had replaced grey iron brakes on 53,000 of its freight cars (85% of their fleet) with newer, quieter models by 2019—in part to comply with a law that came into force in ...

Permanent Mold Casting
Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings. Common casting metals are aluminium, magnesium, and copper alloys. Other materials include tin, zinc, and lead alloys and iron and steel are also cast in graphite molds.. Typical products are components such as gears, splines, wheels, gear housings, pipe fittings, fuel injection housings, and automotive engine pistons. Process There are four main types of permanent mold casting: gravity, slush, low-pressure, and vacuum. Gravity process The gravity process begins by preheating the mold to 150–200 °C (300–400 °F). to ease the flow and reduce thermal damage to the casting. The mold cavity is then coated with a refractory material or a mold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, and more. Traditional techniques include lost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refractory
In materials science, a refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, non-metallic, porous, and heterogeneous. They are typically composed of oxides or carbides, nitrides etc. of the following materials: silicon, aluminium, magnesium, calcium, boron, chromium and zirconium. ASTM C71 defines refractories as "...non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above ." Refractory materials are used in furnaces, kilns, incinerators, and reactors. Refractories are also used to make crucibles and moulds for casting glass and metals and for surfacing flame deflector systems for rocket launch structures. Today, the iron- and steel-industry and metal casting sectors use appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
