Abstract: A firearm with a frame, a slide, a striker, and a striker retaining system. The striker is connected to the frame inside the slide. The striker has a firing pin biased by a spring in a forward direction. The retaining system has a retainer pin and a spring. The retaining pin is mounted to the frame and is adapted to automatically engage the striker when the slide is removed from the frame. This prevents the striker from being inadvertently released as a projectile off of the frame when the slide is not mounted to the frame.

Abstract: An improved electromagnetic launcher (10; 98; 150) has a barrel (20; 100) formed by at least one pair of bus-bars (30, 32; 102, 104; 156, 158; 184, 184, 188, 190) to transport current longitudinally along the barrel. The barrel includes a bore (36; 108) which is spaced from the bus-bars by a bore structure (34; 106). The bore structure guides an elongated, tapered metal armature (44; 122; 164) through the bore. The current to the armature passes from the bus-bars through an array of deformable contactors (54, 55; 110, 112) disposed near the bore walls and in series with resistors (60, 62, 64, 66; 114, 116, 118, 120). The resistors distribute current and electromagnetic driving force along the armature. A conductive implodable shield (130) confines the bore structure and the bus-bars to impede repulsion of the bus-bars and to compress the magnetic flux between the shield walls and the bus-bars.

Abstract: Azimuth and elevation information relating to ground based weapons equipment is inputted to a north finding system. The system determines angular azimuth and elevation errors and transmits signals to a display arrangement for indicating the direction to rotate the system so as to eliminate the errors. As the system is aimed, a gyro included in the north finding system measures angular rotation about its input axis and accelerometers measure the change in tilt. The computer projects the rotations to the horizontal plane and determines the change in azimuth. This is a continuous procedure until all errors are eliminated.

Abstract: An adjustable firearm support for use in adjusting the sights of a firearm is disclosed. The firearm support includes a substantially horizontally disposed tube having an armrest movably attached to one end thereof and a gun cradle movably attached to an opposite end thereof. A telescopic stand is pivotally and slidably coupled to the tube by a clevis and facilitates providing vertical support for the tube. The stand, in turn, may be releasably clamped to the stationary object. The clevis is rotatably engageable with the tube so as to permit the tube to be rotated in a horizontal plane. The clevis is further pivotal so as to permit the tube to be pivoted in a vertical plane. The firearm support is not limited in its application to adjusting firearm sights but may be set up at a hunting site, and attached to a tree stand or other solid object, for use in providing a steady rest when sighting and firing at game.

Each transmit signal is taken off the MMIC chip by a dielectric waveguide and directed to the antenna system. The receiver module includes three receivers that are selected sequentially to provide a beam azimuth scanning function.

Abstract: An augmented service pistol weapons system and ammunition has an extended barrel and an adapter sleeve and mount which supports the barrel and partially surrounds a forward end of the service pistol. Two hinged flaps have inward extending clamps which engage an inside of the front of a trigger guard on the pistol. A turn-to-release locking pin holds the two flaps together as the flaps are closed on the trigger guard. An arm rest extends laterally rearwardly along sides of the pistol and terminates in a curved rearward extension to support the augmented service pistol on an arm of the user. A fifty round magazine replaces the standard pistol handle magazine. Scopes and aiming devices are mounted above the extended barrel. A foregrip is removable and positionable at opposite lateral sides of the extended barrel and below the barrel. A variable power function assembly surrounds the barrel and allows selected release of gas to slow projectiles. A shredding device near the muzzle shreds bands on the projectile.

Each segment is formed with complemental arcuate tab and recess formations for allowing pivoting of adjacent segments relative to one another.

Abstract: A system and method that provides for all-weather precision guidance of conventional air-to-surface weapons. The system and method employs a coherent monopulse radar disposed on a launch platform and a noncoherent passive (receive only) radar disposed on the weapon. The synthetic aperture radar generates a synthetic aperture radar monopulse map of an area around the target. The radar is used designate the location of the target, and transmit a sequence of alternating sum and simultaneous azimuth and elevation difference patterns centered on the target. The weapon includes a guidance system and seeker that is responsive to guidance commands transmitted by the synthetic aperture radar. The guidance system and seeker receives reflections of the alternating sum and combined azimuth and elevation difference pattern from the target, and the sum pulse is used by the weapon to acquire and track the azimuth and elevation difference pattern null on the target to fly an optimum trajectory to the target.
