    摘要： Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from compacted metal powders that may include an anti-sparking agent. The compacted metal powders may be or include a compacted mixture of metal powders that may include powders of one or more of iron, zinc, bismuth, copper, tungsten, nickel, boron, and/or alloys thereof, and/or oxides thereof. The compacted mixture may be heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. The anti-sparking agent may include a borate, such as boric acid.

    摘要： The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted.The method envisioned produces projectile bodies from rod or wire stock by encasing identification tag material, and swaging a projectile body with a wholly or partially encased tag with indicia. The stock may be extruded around premade identification tags or a recess may be reverse extruded in each slug. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.

    摘要： A firearm is provided that includes a receiver, a stock, an elongated barrel and a muzzle. The barrel extends from the receiver to the muzzle and has a rectangular internal bore extending from the receiver to the muzzle. The internal bore has two short sides and two long sides. A plurality of teeth extends along one of the short sides within the internal bore. A disk-shaped bullet fitting within the internal bore may be fired from the firearm. A bullet case having a rectangular orifice is provided to chamber the disk-shaped bullet for propulsion through the rectangular internal bore of the firearm.

    摘要： A non-lethal, sabot-deployed blast shield mitigates a suicide bomber by wrapping around the bomber and positioning a plurality of protective layers over an explosive device to absorb emitted heat, shock waves, and projectiles if the device is detonated. Stand-offs such as inflatable beams or pillows provide break-away zones between the protective layers, allowing some layers to expand to a point of failure and absorb the maximum possible energy. Inner layers absorb shock waves and heat. One or more outer layers resist projectile penetration. Protective layers can be positioned on opposing sides of a suspect in case two explosive devices are present. Shields can deploy with sufficient energy to knock down a bomber. In embodiments, a plurality of shields can be applied without interference therebetween. In some embodiments, a round shield includes bolas which spread the shield in flight in a cast-net dynamic and wrap around the suspect for shield attachment.

    摘要： A three component bullet with an improved core retention feature and a method of manufacturing the bullet is described including a cylindrical jacket having an open end and a closed end containing a malleable metal core which is forced into a forming die having a bottleneck shaped interior resulting in a bottleneck shaped pre-form wherein the outside diameter of the open-ended forward portion of the jacket is smaller than the outside diameter of its closed rearward portion. The open end of the pre-form may be dropped through or forced through a malleable locking band of appropriate height, diameter and wall thickness. A relatively tight-fitting punch enters the open end of the pre-form generating sufficient axial force against the face of the metal core to radially swell the core and subsequently portions of the jacket fore and aft of the locking band, thereby securing the locking band in place while at the same time producing an inwardly-extending annular band of jacket material which embeds itself into the core material with the result that the core is permanently locked inside the jacket.
