| 20080257192 | High Muzzle Velocity Projectiles and Barrels - A projectile firing apparatus having a barrel ( | 10-23-2008 |
| 20090084282 | Propellant Sealing System for Stackable Projectiles - A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile includes a chamber containing a propellant charge, with an exit from the chamber for release of propulsion gases into the barrel. A seal blocks the exit and is opened by ignition of the propellant within the chamber but is resistant to gases produced by ignition of propellant in other projectiles in the barrel. The exit and seal are provided in a range of different forms. The exit may be an aperture in a wall of the chamber with the seal as a moveable barrier, such as a valve-like structure, for example. The seal may also include a rupturable or deformable barrier across the aperture. Alternatively the seal is a thin barrier around the charge such as a wax coating and the exit involves a disintegrable character of the barrier. The seal may also be an inherent property of the geometry of the chamber. | 04-02-2009 |

| 20090173250 | SYSTEM FOR PROTECTION AGAINST MISSILES - A system is disclosed for defeating enemy missiles and rockets, particularly rocket propelled grenades (RPG's). The first step is to identify the firing of a missile by the use of sensors that give the approximate distance and bearing of the incoming missile. A non-lethal cloud of pellets is then launched from the target, which can be a building or vehicle or the like, in the general direction of the missile. The pellets are housed in a series of warhead containers mounted at locations on the target in various orientations. The warheads are triggered to fire a low velocity cloud of pellets toward the incoming missile. The pellets then collide with the missile a certain distance away from the target causing premature detonation of the missile, and/or possible severe damage to the missile, and/or deflection of the missile, due to the relatively high velocity of the missile. | 07-09-2009 |

| 20100282110 | GUN FIRING METHOD FOR THE SIMULTANEOUS DISPERSION OF PROJECTILES IN A PATTERN - A gun firing method whereby multiple projectiles segments that are contained within a cartridge are fired simultaneously in a symmetrical pattern. Some of the multiple projectile segments are modified by moving the center of mass of the projectile segments away from the central longitudinal axis of the cartridge. This in combination with bring fired from a rifled gun barrel will impart velocity to the modified projectile segments upon exiting the gun barrel at right angles to the gun barrel. This velocity along with the higher muzzle velocity will cause the modified projectile segments to diverge away from the trajectory of a standard projectile segment and strike the target away from the bullseye. The magnitude of the divergence will vary with the distance the projectile segment's center of mass is away from the central longitudinal axis of the cartridge. The placement of the modified projectile segments strikes around the bull's-eye will be determined by the orientation of the centers of mass of the modified projectile segments prior to firing. Simultaneously firing a multiplicity of standard and modified projectile segments will produce a symmetrical pattern on a target, which will substantially increase the hit probability of a gun. | 11-11-2010 |
