  • Patent number: 6279258
    Abstract: A short bolt rifle that enables increased barrel without an increase in weight. A longer barrel increases bullet velocity, which increases the range and accuracy of the weapon and the bullet impact energy. In this action, the bolt is simply pulled back and pushed forward. The design includes a loader mechanism that ejects spent cartridges and loads a new cartridge. This happens while the bolt is drawn back and pushed forward. A rotating lock secures the bolt in the firing position. A second version of the action uses a pistol grip. A lock holds the pistol grip, which can be released. After it is released, the user pulls down and back on the grip to open the action. The grip is pushed forward and upward, to load a shell, while the bolt is moved forward and locked. The action also can easily be adapted to fully automatic operation.

  • Patent number: 6223461
    Abstract: A safety system and method for remotely activating and/or deactivating firearm(s). In certain embodiments, at least one processor or chip may be provided in the firearm. In order to remotely activate a firearm and allow it to be discharged, a controller (located remotely from the firearm) causes an activation signal to be sent to a satellite. The satellite redirects the activation signal toward a particular geographical area. When the firearm to be activated is in that geographical area, it receives the activation signal from the satellite. Upon determining that a match is found between a code in the received activation signal and a predetermined activation code stored in a memory of the firearm, the processor in the firearm causes a trigger lock in the firearm to open thereby enabling the firearm to be discharged whenever a user should decide to load the weapon and pull the trigger.

  • Patent number: 6205903
    Abstract: A line charge has a series of spaced-apart warheads coupled to strength members and a detonating cord freely extends through bores in the warheads. A rocket motor at one end of the strength members pulls the line charge across an obstacle laden area. An anchored tether or drogue chute at the other end arrests flight of the line charge and it drops across the area. The thermoplastic, polymeric, or metallic strength members provide strain management to withstand the severe deployment forces and to preclude damage to the detonating cord. Strain is absorbed by the elastic deformation of the strength members coupled to the warheads. Strain also is reduced through direct dissipation of energy by dynamic frictional losses created between strength members, coupling components, and anchoring devices during deployment when slippage occurs between the strength members and coupling components and anchoring devices.

  • Patent number: 6112636
    Abstract: A gas-operated pistol which comprises a frame having a handgrip and adapted to receive a magazine. A slide is mounted for alternating longitudinal movement along the frame. A barrel is provided which is able to pivot at its muzzle end and rotate upwards from a locking engagement via locking means with the frame to allow a cartridge to be removed. An actuating means rotates the barrel upwards after the high pressure period has passed. A cylinder is located above the barrel and communicates with the barrel bore via a passage. The action of propellant gases in the cylinder on the piston urges the slide rearwards. This arrangement reduces the effect of felt recoil on the firer when using very powerful cartridges.
