The Pedersen rifle was rejected a month before Gen. MacArthur pronounced on the subject, at a point in time when the caliber .276 T3E2 Garand rifle was the clear winner of the competition and ready for initial production.
The Pedersen device was an experimental weapon attachment for the M1903 Springfield bolt action rifle that allowed it to fire a .30 caliber (7.62 mm) ...
The .276 Pedersen was a shorter, lighter and lower pressure round than the .30-06, which made the design of an autoloading rifle easier than the long, powerful .30-06. The U.S. Army Chief of Staff Gen. Douglas MacArthur rejected the .276 Pedersen Garand in 1932 after verifying that a .30-06 version was feasible.
Mine exploder T3E2 flail – E1 variant, rotor replaced with steel drum of larger diameter. Development terminated at war's end. Development terminated at war's end. Mine exploder T4 – British Crab II mine flail.
Twenty gas-operated .276 T3E2 Garands were made and competed with T1 Pedersen rifles in early 1931. The .276 Garand was the clear winner of these trials. The .30 caliber Garand was also tested, in the form of a single T1E1, but was withdrawn with a cracked bolt on 9 October 1931.
This step could be replaced by the Pedersen process -- either result in alumina. Unlike the smelting processes of iron and coal into steel or copper and tin into bronze, which require thermal energy, alumina must be smelted with electrical energy. This is done through the Hall–Héroult process, producing 99.5–99.8% pure aluminum. [2] [7]
A Pedersen current is an electric current formed in the direction of the applied electric field when a conductive material with charge carriers is acted upon by an ...
The Christie M1931 originated as the M1928, which used Christie's suspension, and had the ability to run on its tracks or the wheels.The M1928 was demonstrated unofficially to the US Army by traversing a route at an average speed of 45 km/h (28 mph); by contrast the US Army's T1E1 tanks – expected to replace their WWI-era M1917 light tanks – averaged 16 km/h (9.9 mph) over the same route.
