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, for ..., 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 is att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synchronization Gear
A synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon. Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 191 ...
