  • Patent number: 7988381
    Abstract: A vehicle disabling apparatus may include at least one plunger assembly having a plunger and a toggle operable to pivot inside the vehicle tire. The apparatus may include energetic material disposed adjacent the plunger and configured to force the plunger into a vehicle tire. A method of disabling a vehicle having a tire may include using the vehicle's tire to move the plunger and thereby activate the energetic material; and moving the plunger into the tire using gas produced by the energetic material.

  • Patent number: 7451702
    Abstract: An electrically-fired round includes a case sized to fit in a conventional large caliber gun; a launch tube disposed in the case; a plurality of projectiles axially stacked in the launch tube; each projectile comprising a cylindrical body having a circular lid that closes the forward end and a circular base that closes the rear end, the circular lid and the circular base defining a payload volume therebetween, the circular base including a cavity formed therein, a propellant charge disposed in the cavity, and an igniter disposed in the propellant charge; a case base plate that closes a rear end of the case; and electrical connections between the case base plate and each igniter.

  • Patent number: 7418896
    Abstract: A recoilless weapon system is provided rear portion, a barrel in movable connection to the rear portion, and a handle portion in removable connection with the barrel and/or rear portion. Further, a ballast payload cartridge is removably disposed within a ballast payload cartridge portion of said rear portion, and serves as a center breach to support a combat cartridge. The ballast payload cartridge may have a side primer disposed therein, which allows a single weapon firing pin to simultaneously initiate both the combat cartridge primer and the ballast payload cartridge primer.

  • Patent number: 7380488
    Abstract: A firing adapter for a combination gas and recoil operated weapon includes a blank firing barrel attached to the weapon; a piston having a barrel end and an anchor end, the barrel end being reciprocably disposed in the blank firing barrel and the anchor end being fixed to a non-recoil surface; and a gas port formed in the blank firing barrel wherein in a rest position of the weapon, the barrel end of the piston closes the gas port, and in a recoil position of the weapon, the barrel end of the piston opens the gas port.

  • Patent number: 7207276
    Abstract: A non-lethal ammunition utilizes dense powder ballast and a two-stage firing sequence for launching non-lethal projectiles of a caliber range from approximately 5.56 mm through approximately 40 mm. The non-lethal ammunition comprises a non-lethal cartridge. The non-lethal cartridge comprises a dense powder ballast and one or more non-lethal projectiles. The dense powder ballast is more massive than the non-lethal projectile providing sufficient payload mass to operate the weapon mechanism while launching the non-lethal projectile at velocities compatible with non-lethal applications. A two-stage ignition system fires the non-lethal ammunition and subsequently fires the more massive dense powder ballast. The firing events are separated by a time delay of less than a second. The non-lethal ammunition provides non-lethal projectile capability for semi-automatic and automatic weapons.

  • Patent number: 7055422
    Abstract: An improved Barrett anti-armor gun that is modified to function from the open bolt with advanced primer ignition, wherein the forward momentum of the recoiling masses at the moment of firing offset a significant portion of the recoil impulse from firing. The modification reduces the recoil energy absorbed by the shooter.

  • Patent number: 6178889
    Abstract: A low impulse telescoping cartridge includes a case, a piston, a projectile, and a link. The projectile is seated into the forward portion of the piston. Gas passages permit propellant gases to bleed into the cavity behind the projectile and to accelerate the projectile upon firing. An alternative to using bleed gases is to use a separate propelling charge behind the projectile. The case and piston are assembled and telescopically secured by means of a crimp or other similar feature, to allow relative movement therebetween during chambering and firing. The link may be allowed to move for some portion of the required relative travel between the link and the base of the case. A shoulder on the piston provide a stop through which reaction loads are transmitted to the rear of the barrel during chambering and firing. The piston telescopes over the case during chambering to provide the relative movement between the link and the case base required for weapon function.
