Abstract: The expanding bullet assembly incorporates a bullet head which incorporates an axial borehole extending from the rear of the bullet head towards the tip but not reaching the tip. The bullet head can incorporate longitudinal serrations or grooves and/or circumferential grooves which aid in separation upon impact. The borehole receives a shaft made of brass, copper or other metal harder than the leaden bullet. The shaft (or pin) extends from the back of the bullet and is connected to an inertial fragmenter, which is separated somewhat from the bullet head. The fragmenter can have tapered or sloped sides adjacent the back of the bullet for wedging into and forcing apart the fragments of the bullet. The bullet head can be round, pointed or hollow pointed. The shaft end near the bullet tip can alternatively be an integral expanded shaft tip having the shape of a sphere.

Abstract: The gun has two parts. The first part is an ordinary gun with an ammunition feeder, a chamber and breech and a barrel. The second part has electromagnet assemblies, which includes plural electromagnets serially arranged in gradually reducing spirals. Equal electromagnets are arranged on opposite sides of the bore in two or three or more equally counter rotating cylinders. The electromagnets are sequentially energized beginning when a sensor along the barrel senses the passage of the powder propelled projectile. The reduction in angular twist of the magnets and the increased linear steps near the muzzle uniformly linearly accelerates the projectile through the electromagnetic drivers. Pairs of magnets allows increased number of electromagnets with sufficient space between contacts and magnets. A firing pin is activated at a precise time to deliver the accelerating projectile to the accelerated by the first electromagnets as the rotating assemblies position the first magnets along the gun.

Abstract: A backpack carrier has a lightweight metal frame embedded in KEVLAR. The KEVLAR is preferably wrapped to form a plurality of layers over the metal frame and the plural layers are held together by the epoxy portion of the KEVLAR which integrally binds laminations of woven carbon-based fabric. The carrier is shaped to provide a substantially bulletproof shield and may also be used as a rifle support by placing the barrel of a rifle in a V-shaped notch provided in an upper portion of the shield.

Abstract: A ballistic face shield is provided for military use and acts to deflect penetrating bullets. Thickness is avoided by angling the orientation of the shield and by providing an explosive charge which launches the shield forwardly and upwardly when an outer layer of the shield is shattered. The shield construction includes glass, inert gas and plastic layers.
