Abstract: An apparatus for simulating the recoil force of a weapon A recoil force generator is coupled through a linkage to the weapon in such a manner that the recoil force is substantially coaxial with the axis of the weapon over wide variations in weapon aiming positions. The simulated recoil force is also used to provide simulation of weapon recocking, round counting and empty weapon simulation.

Abstract: An apparatus for automatically determining without human intervention the intersection point of the axis of an aimable optical system with a plane. A scanning radiation source is imaged on a radiation sensor array by a movable focusing reflector. The signal output from the sensor array is electronically processed to determine the intersection point of the optical axis of the focusing reflector on a target plane. When the apparatus is used as a weapon training simulator, a shot sound synthesizer imparts additional realism.

Abstract: A lubrication pump and filter are mounted to an access cover for the final drive of earthmoving equipment together with necessary interconnecting lubricant lines. The pump and the filter can both be removed from the access cover without removing the other and without removing the cover. Both the pump, filter and lines affixed to the access cover can be removed or installed as a unit.
Abstract: A toilet tank flapper valve providing user selection of either a full or partial dispensing of the liquid contents of the tank. A novel ball-check valve particularly located in the flapper valve either obstructs water from entering or permits it to enter the buoyancy chamber of the flapper valve. When water is permitted to enter, a partial dispensing action results.
