The Pedersen Rifle, officially known in final form as the T1E3 rifle, was a United States semi-automatic rifle designed by John Pedersen that was made in small numbers for testing by the United States Army during the 1920s as part of a program to standardize and adopt a replacement for the M1903 Springfield.
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.
The use of the Pedersen device in the 1919 spring offensive was to be in conjunction with the full combat introduction of the M1918 Browning Automatic Rifle (BAR.) The US Patent Office issued U.S. patent 1,355,417, U.S. patent 1,355,418, U.S. patent 1,355,419, and U.S. patent 1,355,420 to Pedersen for his invention. The United States Army paid ...
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 The .30 caliber Garand was also tested, in the form of a single T1E1, but was withdrawn with a cracked bolt on 9 October 1931.
Pedersen currents emerge in a material where the charge carriers collide with particles in the conductive material at approximately the same frequency as the gyratory frequency induced by the magnetic field. Pedersen currents are associated with a Pedersen conductivity [1] related to the applied magnetic field and the properties of the material ...
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.
Crown ether coordinating a potassium ion. Charles John Pedersen (Japanese: 安井 良男, Yasui Yoshio, October 3, 1904 – October 26, 1989) was an American organic chemist best known for discovering crown ethers and describing methods of synthesizing them during his entire 42-year career as a chemist for DuPont at DuPont Experimental Station in Wilmington, Delaware, and at DuPont's Jackson ...
John Walter Christie (May 6, 1865 – January 11, 1944) was an American engineer and inventor. [1] He is known best for developing the Christie suspension system used for several World War II-era tank designs, most notably the Soviet BT and T-34 [3] tanks series, and the United Kingdom Covenanter and Crusader Cruiser tanks, as well as the Comet heavy cruiser tank.
