Abstract: A combustion activated tool includes a housing having a longitudinal bore that extends and connects with a vertical bore, a piston and piston guide disposed within the longitudinal bore and moveable axially therein, and an advance lever having a reset end and an advancing end, the lever disposed on a pivot skew to the axis of the longitudinal bore, the lever having an axis essentially parallel with the longitudinal bore, the advancing end of the lever attached on an arm of the lever angled to one side of the axis of the longitudinal bore and effective to engage teeth on the side of a strip of charges disposed in the vertical bore, the reset end of the lever being disposed on the same side of the axis of the longitudinal bore engaging the piston guide along an edge of the lever.

Abstract: In connection with this ammunition-feeding device, an axial transport device (19) with a conveyor chain (34) is provided between a conveyor (6) and a transfer station (20) for transferring cartridges (2) to a revolver drum (25) of a revolver cannon, by means of which the cartridges (2) are displaced in their longitudinal direction during transport vertically in respect to the movement direction of the conveyor chain (34). A buffer shaft (35) is provided for driving the conveyor chain (34), wherein the drive by means of the buffer shaft (35) takes place in such a way that, prior to being transferred to the transfer station (20), the cartridges (2) are brought into a buffer position.

Abstract: Disclosed herein is an apparatus for separating consecutive cartridge-receiving cells of a driven magazine for an aircraft-mounted machine gun or cannon. The apparatus includes an elongated, substantially cylindrical shaft constructed of a fiber-reinforced plastic, wherein the shaft has end portions designed for attachment to a movable transport chain, and a middle portion defined by a driver constructed of an elastomer. The driver preferably dampens the gravitational forces introduced to the shaft.

Abstract: An automotive HVAC system controls two side by side film belts with a single drive motor. Two co planar wind up rollers, one for each belt, have inboard ends that are indirectly connected by a rotation transmission means that has a defined level of turning “slack”. Rotation is transmitted from one wind up roller to the other only after the slack has been taken up, allowing a certain degree of offset between the two belts. When a first belt is turned past a first position, it eventually moves the other belt to a new position, with the defined belt offset maintained. The first belt can then be turned back, breaking the indirect connection between the two shafts.

Abstract: A machine gun, representatively a 30 mm machine gun, is mounted on an outer end portion of a support plank structure projecting out of the cabin area of a helicopter using a roller cradle assembly secured to the outer plank end. A variety of structural improvements are incorporated into the machine gun to (1) reduce its mechanical complexity, (2) reduce its firing recoil to make the gun more suitable for light aircraft mounting, and to improve the gun's firing controllability and accuracy, and (3) to make the gun easily and quickly field strippable, for cleaning, inspection and repair purposes, without requiring the services of a highly skilled armament mechanic or taking the gun to a specialized repair facility.
