Abstract: A parking lock actuation system for a motor vehicle includes an actuation element that can be moved between a locking position, in which a parking lock of the motor vehicle is active, and an unlocking position, in which the parking lock is inactive. The system also includes a locking element which is designed to fix the actuation element in the unlocking position in a form-fitting manner; and an electric actuator which has an adjusting effect on the locking element. A current circuit which has an autonomous power source is connected to the electric actuator, and a bistable switch and a monostable opener arranged in series to the bistable switch are used in the current circuit.

Abstract: A weapons system has a stationary base and an assembly that has the tube mounted on it, that pivots in the direction of elevation, and that is mounted on a trunnion in a stationary base. The center of gravity of the pivoting assembly is outside the axis of rotation of the trunnion. A torque that opposes the moment of unbalance is generated by at least one suspension mechanism consisting of at least one torsion-bar suspension mechanism, one end of which is non-rotationally secured to the base and the other end of which is secured to the weapon's pivoting assembly by way of a transmission mechanism. The transmission mechanism contains at least one additional suspension element.

Abstract: An unbalance-compensating device for a weapons system, especially a heavy weapon, with an assembly that has the tube mounted on it, that pivots in the direction of elevation, and that is mounted on a trunnion in a stationary base, whereby the center of gravity of the pivoting assembly is outside the axis of rotation of the trunnion and wherein a torque that opposes the moment of unbalance is generated by at least one suspension mechanism. The suspension system consists of at least one torsion-bar suspension mechanism, one end of which is non-rotationally secured to the base and the other end of which is secured to the weapon's pivoting assembly by way of a transmission mechanism.

Abstract: A mechanism for feeding the shells to a weapon one at a time comprises a conveyor for removing one shell from at least one ammunition magazine comprising a frame, mounted for rotation about an axis perpendicular to a floor for movement from a pick-up position to a transfer position, rails on the frame disposed parallel to the floor, an arm slidably mounted on the rails for movement therealong parallel to the floor, a gripper mounted on the arm for gripping a shell and pivotable from a first position wherein the shell is upright to a second position wherein the shell is aligned with the length of the vehicle. The gripper is operative in the first position to grip a shell when the frame is in the pick-up position and is operative in the second position to release a shell when the frame is in the transfer position. A shell tray is mounted for sliding movement parallel to the floor between a receiving position wherein the tray receives a shell released by the gripper and a holding position.
