Abstract: An apparatus for manufacturing an ammunition article, includes forming a projectile of an ammunition article at a first station of an apparatus, transporting the projectile within the apparatus to a second station of the apparatus, and injection molding at the second station a cartridge casing body of the ammunition article around at least a portion of the projectile.

Abstract: A base for a cartridge casing body for an ammunition article, the base having a ignition device; an attachment device at one end thereof, the attachment device being adapted to attach the base to a cartridge casing body; wherein the base is made from plastic, ceramic, or a composite material.

Abstract: An ammunition article includes a molded plastic cartridge casing body having a first end and a second end, and a projectile attached to the first end of the cartridge casing body. The cartridge casing body is molded around at least a portion of the projectile. A molded plastic base for an ammunition article, a molded plastic blank cartridge, and a molded plastic cartridge casing body having a pronged web are also disclosed.

Abstract: Creating relatively pure and consistent crystals of high performance minerals, such as diamond, has long been pursued. Unfortunately, synthesizing crystals that exhibit deep bonding generally requires high temperatures and high pressures for the formation of large crystals. Alternatively, high pressure and explosive shock waves can also be utilized, as demonstrated by closed-bomb diamond synthesis. Diamond crystal formation at lower temperatures and pressures have been demonstrated, but the formations have been thin and inconsistent. A method of forming diamond and the synthesis of other high performance crystals that are consistent, and can be grown to larger sizes has not existed, nor has a means of providing uniform and consistent thin layers of diamond and other such crystals been demonstrated.

Abstract: A method and apparatus for eliminating heat build-up caused by air friction on wings and other air foils, especially common in high-speed aircraft. As an aircraft is moving, a small portion of air in the airstream moving by the wing or other air foil is passed through an air intake valve on the wing, into a Venturi section and then into a chamber within the wing or frame where the air is compressed naturally. Each Venturi section consists of a converging and diverging nozzle which creates a substantial cooling effect when the high speed air passes through it and is compressed and released. The intake valve spins or flips when hit by the airstream so it alternately intakes and exhausts the air through the Venturi section, thereby causing a double cooling effect. A second embodiment uses valves, one on the leading edge for air intake and the second near the back of the lower surface of the wing for air exhaust.

Abstract: A structure for a weapon apparatus that can be made of polymer materials is provided. In addition to many novel features, including a counter-torque muzzle cap, an operating handle and gas-operated link, this weapon apparatus has a unique firing mechanism as specifically claimed herein. The firing mechanism comprises a trigger bar having a cantilever-shaped release spring for biasing the trigger bar forward and an upwardly extending disconnector protruding into the path of the hammer. A rotating safety to lock the sear mechanism is also provided.

Abstract: An automatic or semi-automatic pistol is made substantially of polymer materials. The pistol includes polymer upper and lower receivers and a polymer barrel attached to the upper receiver. The operating mechanism includes a bolt, block and a hammer, slidably mounted in the fixed upper receiver with the bolt and block and the hammer being separately springloaded. A gas operated link is positioned to rotate the pistol block from a locked to an unlocked position when actuated by gas from a fired cartridge. A gas port extends from the end portion of the barrel to one end portion of the gas operated link to move the link responsive to the gas pressure to thereby unlock the block so that the block, bolt and hammer can be operated by reaction to the gasses still in the weapon barrel.
