Abstract: An ammunition feed system wherein a single layer of alternatingly opposing rounds of ammunition is conveyed in a magazine by a single closed loop conveyor disposed along a serpentine path. The opposing rounds are fed into a twister conveyor apparatus which aligns the rounds and conveys the aligned rounds onto a pair of parallel paths. The aligned rounds on the parallel paths are received by a pair of feed rotors for alternate insertion into a single gun feeding conveyor. Spent rounds are withdrawn from the conveyor by a pair of return rotors, which return the spent rounds to a second twister conveyor. The second twister conveyor reorients the rounds into an alternating opposed configuration and returns the rounds to the serpentine path. Each twister conveyor includes two pairs of sprockets oriented in a perpendicular configuration. Each pair of sprockets carries one closed loop of conveyor elements for conveying rounds.

Abstract: An ammunition feed system wherein a single layer of ammunition is conveyed in a magazine by two independent closed loop conveyors disposed side by side in parallel, serpentine paths. Live rounds are fed on parallel output paths into first and second expansion rotor systems which, in turn, supply the rounds to a pair of feed rotors which insert the rounds alternately into a gun feeding conveyor. Spent rounds are withdrawn from the conveyor by a pair of return rotors, which, in turn, supply third and fourth expansion rotors, which return the spent rounds to the first and second parallel serpentine paths. The feed and return rotors contain pockets for receiving rounds alternating with surfaces for guiding rounds and cooperate with the expansion rotors to double the rate at which ammunition exits the system over that at which it is transferred out of the magazine.

Abstract: A kit and method for constructing a temporary key template from a key code of a lock having pin tumblers is disclosed. The temporary key template is used as a master in order to make a permanent duplicate key having appropriate serrations from a suitable uncut key. The kit includes a converter blank key having an elongate bar in which a plurality of apertures are provided. These apertures are spaced at predetermined distances from one another which correspond to the respective distances between the pin tumblers of the lock. A plurality of different pins are provided which are adapted to be inserted into any of the apertures so that a predetermined upper portion of the pin extends above the elongate bar. The particular pin need for an aperture is determined by the key code so that by filling the appropriate apertures with appropriate pins, a temporary key template is constructed which is easily duplicated on a conventional key duplicating machine.

Abstract: An elongated, aerodynamically improved ballistic projectile fuse, having an overall fuse length greater than its maximum diameter by a factor of approximately two, includes a lightweight aluminum fuse body having forward and rearward portions and an interiorily disposed firing pin with a shearable flange thereon. A steel sleeve mounted in the fuse body is provided for supporting the firing pin with a head portion thereof forwardly directed and exterior to the sleeve and for guiding the firing pin through the fuse body toward the rearward portion thereof subsequent to impact of the fuse with a target. A cap, enclosing the firing pin head, is configured for collapsing and impacting the head upon fuse impact with a target, thereby causing shearing of the firing pin flange and driving of the firing pin rearwardly toward detonation means disposed within the fuse body rearward portion. The cap is in turn enclosed by a windscreen which provides an aerodynamically streamlined, forward continuation of the fuse body.
