Colt Army and Navy revolvers both employed gain-twist rifling. Gain-twist rifling, however, is more difficult to produce than uniform rifling, and therefore is more expensive. The military has used gain-twist rifling in a variety of weapons such as the 20 mm M61 Vulcan Gatling gun used in some current fighter jets and the larger 30 mm GAU-8 ...
A beam waveguide antenna is a type of complicated Cassegrain antenna with a long radio wave path to allow the feed electronics to be located at ground level. It is used in very large steerable radio telescopes and satellite ground antennas, where the feed electronics are too complicated and bulky, or requires too much maintenance and alterations, to locate on the dish; for example those using ...
This revolver uses gain-twist rifling, starting with a slow twist rate of one turn in 100 in and gradually increasing up to one turn in 20 in to accommodate the combination of a heavy bullet and high pressure and velocity typical for the round. [3]
A gain greater than one (greater than zero dB), that is, amplification, is the defining property of an active device or circuit, while a passive circuit will have a gain of less than one. [4] The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power ...

When the left and right wheels move together the bar simply rotates on its central mounting points. When the wheels move relative to each other, torsion forces cause the bar to twist. Each end of the bar is connected to an end link through a flexible joint. The link is connected in turn to a spot near a wheel or axle, transferring forces from ...
