Cleveland Diesel Engine Division
The Cleveland Diesel Engine Division of General Motors (GM) was a leading research, design and production facility of diesel engines from the 1930s to the 1960s that was based in Cleveland, Ohio. The Cleveland Diesel Engine Division designed several 2 stroke diesel engines for submarines, tugboats, destroyer escorts, s and other marine applications. Emergency generator sets were also built around the Cleveland Diesel and were installed in many US warships. The division was created in 1938 from the GM-owned Winton Engine Corporation and was folded into the GM Electro-Motive Division in 1962. The engines continue in use today on older tugs. History Cleveland Diesel traces it roots to the Winton Gas Engine and Manufacturing Company, which was formed by the early Cleveland automobile manufacturer Alexander Winton in November 1912. Winton soon expanded into production of heavy spark-ignition and diesel engines, introducing the first American diesel in 1913. Renamed the Winton ...

Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or Scavenging (automotive), scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringe ...

Farrel Corporation
The Farrel Corporation is an American manufacturing company based in Ansonia, Connecticut. Today, they manufacture process equipment for the plastics industry, and employ roughly 100 people. History Farrel was founded in 1848 as a foundry by Almon Farrel. During the American Civil War, they produced bayonets and cannon barrels. In 1926, Farrel Foundry merged with Birmingham Iron Foundry of Derby, Connecticut. During the 1920s, Farrel-Birmingham began creating gears for use in US Navy propulsion systems in Buffalo, New York. In 1941, the Navy contracted with Farrel-Birmingham and General Motors to begin manufacturing a rapid reversal gear system that would allow vessels to reverse engines without first slowing down. In 1942, Farrel-Birmingham received the E award from the Navy for their efforts. In 1963, Farrel Birmingham adopted the current name of Farrel Corporation and began manufacturing process equipment for plastic plants. During the 1970s and 1980s, Farrel went thro ...

Roots Blower
The Roots blower is a positive displacement lobe pump which operates by pumping a fluid with a pair of meshing lobes resembling a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. The Roots blower design does not incorporate any reduction in volume/increase in pressure as air or other fluid passes through, hence it can best be described as a blower rather than a supercharger unlike some other designs of "supercharger" such as cozette, centric, Shorrock supercharger, Powerplus supercharger and also the axial flow Eaton type supercharger which have internal "compression". The most common application of the Roots-type blower has been the induction device on two-stroke diesel engines, such as those produced by Detroit Diesel and Electro-Motive Diesel. Roots-type blowers are also used to supercharge four-stroke Otto cycle engines, with the blower being driven from the engine's crankshaft via a toot ...

United States Porpoise-class Submarine
The ''Porpoise'' class were submarines built for the United States Navy in the late 1930s, and incorporated a number of modern features that would make them the basis for the subsequent , , , , , and classes. In some references, the ''Porpoise''s are called the "P" class. Design The four submarines of the ''Porpoise'' and ''Shark'' groups were authorized for construction in Fiscal Year 1934. The two submarines of the ''Porpoise'' group were developed by the Bureau of Construction & Repair at the Portsmouth Navy Yard. It was a full double hull design that was essentially an enlarged ''Cachalot'' (SS-170). The two submarines of the ''Shark'' group were developed by Electric Boat and they were built to a partial double hull design with single hull ends, a refinement of an earlier hull type used on the ''Dolphin'' (SS-169). Six submarines of the ''Perch'' group were authorized for construction in Fiscal Year 1935. The Navy thought the Electric Boat design to be the better of the ...

LaGrange, Illinois
La Grange ( ; often spelled LaGrange) is a village in Cook County, Illinois, United States. It is a suburb of Chicago. The population was 16,321 at the 2020 census. History The area around La Grange was first settled in the 1830s, when Chicago residents moved out to the west due to the rapid population increase in the city in the decade since its incorporation. The first settler, Robert Leitch, came to the area in 1830, seven years before the City of Chicago was incorporated. La Grange's location, at approximately from the Chicago Loop, is not considered far from the city by today's standards, but in that time the residents enjoyed the peace of rural life without much communication with urban residents. The village was officially incorporated on June 11, 1879. It was founded by Franklin Dwight Cossitt, who was born in Granby, Connecticut, and raised in Tennessee, and moved to Chicago in 1862 where he built a successful wholesale grocery business. In 1870, Cossitt purchased se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Nuclear Powered Submarine
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a virtually unlimited range, making the only limits on voyage times factors such as the need to restock food or other consumables. Thus nuclear propulsion solves the problem of limited mission duration that all electric (battery or fuel cell powered) submarines face. The high cost of nuclear technology means that relatively few of the world's military powers have fielded nuclear submarines. Radiation incidents have occurred within ...

Cold War
The Cold War was a period of global Geopolitics, geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 until the dissolution of the Soviet Union in 1991. The term ''Cold war (term), cold war'' is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and Nuclear arms race, nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, Economic sanctions, embargoes, and sports diplomacy. After the end of World War II in 1945, during which the US and USSR had been allies, the USSR installed satellite state, satellite governments in its occupied territories in Eastern Europe and N ...

Pioneer Zephyr
The ''Pioneer Zephyr'' is a diesel engine, diesel-powered trainset built by the Budd Company in 1934 for the Chicago, Burlington & Quincy Railroad (CB&Q), commonly known as the Burlington Route. The trainset was the second internal combustion-powered streamliner built for mainline service in the United States (after the Union Pacific Railroad's M-10000), the first such train powered by a diesel engine, and the first to enter revenue service. The trainset consists of one power/storage car, one baggage/Railway post office, RPO/buffet/coach car, and one coach/observation car. The cars are made of stainless steel, permanently articulated together with Jacobs bogies. The construction incorporated recent advances such as shotwelding (a specialized type of spot welding) to join the stainless steel, and unibody construction and articulation to reduce weight. It was the first of nine similarly built trainsets made for Burlington and its technologies were pivotal in the subsequent dieseliz ...
