Nelson Bohnalite
Nelson-Bohnalite was the name of a piston developed by Adolph Lincoln Nelson in the 1930s and 1940s. The pistons were licensed to Bohn Aluminum and sold to all the major auto manufacturers at the time. These were some of the first pistons to use an aluminum body with a steel strut, allowing for the weight of aluminum and the strength of steel where the piston moves on the piston rod. Many then existing brands of autos used this type of piston in the mid-1930s: Auburn, Graham, Hupmobile Hupmobile was an automobile built from 1909 through 1939 by the Hupp Motor Car Company of Detroit. The prototype was developed in 1908. History Founding In 1909, Bobby Hupp co-founded Hupp Motor Car Company, with Charles Hastings, f ..., Nash, Packard, Pierce-Arrow and Studebaker.

Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolph Lincoln Nelson
Adolph Lincoln Nelson (1888–?) was the inventor of the Nelson Bohnalite piston. He was born in Oneida, Illinois, raised in nearby Galesburg and migrated to Indianapolis where he worked for Premier Motor car. When that company folded he went to Detroit after a stint in Dayton working for the Army Air Force The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II ... on the synchronized airplane-based machine gun. He married Ada Gruber and had 7 Children. They lived in the Palmer Woods area of Detroit.

Auto Manufacturer
The automotive industry comprises a wide range of companies and organizations involved in the design, development, manufacturing, marketing, and selling of motor vehicles. It is one of the world's largest industries by revenue (from 16 % such as in France up to 40 % to countries like Slovakia). It is also the industry with the highest spending on research & development per firm. The word ''automotive'' comes from the Greek ''autos'' (self), and Latin ''motivus'' (of motion), referring to any form of self-powered vehicle. This term, as proposed by Elmer Sperry (1860-1930), first came into use with reference to automobiles in 1898. History The automotive industry began in the 1860s with hundreds of manufacturers that pioneered the horseless carriage. For many decades, the United States led the world in total automobile production. In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, and the U.S. automobile industry produced over 90% of them. ...

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. 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 Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hupmobile
Hupmobile was an automobile built from 1909 through 1939 by the Hupp Motor Car Company of Detroit. The prototype was developed in 1908. History Founding In 1909, Bobby Hupp co-founded Hupp Motor Car Company, with Charles Hastings, formerly of Oldsmobile, who put up the first US$8,500 toward manufacturing Hupp's car. They were joined by investors J. Walter Drake, Joseph Drake, John Baker, and Edwin Denby. Drake was elected president; Hupp was vice president and general manager. Emil Nelson, formerly of Oldsmobile and Packard, joined the company as chief engineer. Hastings was named assistant general manager. In late 1909 Bobby's brother, Louis Gorham Hupp left his job with the Michigan Central Railroad in Grand Rapids and joined the company. Model 20 Hupp Motors obtained $25,000 (equal to $ today) in cash deposits at the 1909 automobile show (the lowest capitalization of Detroit's eight major car makers) to begin manufacturing the Hupp 20. The first cars were bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
