Abstract: An incendiary projectile carries an incendiary charge and a control charge arrangement for igniting and disintegrating the incendiary charge. The control charge arrangement is ignited by the propellant charge which launches the projectile and then immediately ignites the incendiary charge and finally causes disintegration of the projectile. In one embodiment the control charge comprises a first charge, including a glow and delay composition, and a disintegrating charge which is ignited by the first charge. In another embodiment the control charge comprises a glow and delay composition which ignites and then heats the incendiary charge to produce disintegration of the projectile. A novel tubular housing for the control charge is provided to prevent premature disintegration and minimize atomation of the incendiary charge.

Abstract: There is disclosed a handgun intended for one-time use for launching a projectile. The gun is stored in a condition wherein a handle of the gun is folded to cover the trigger. A releasable locking member locks the handle in its folded position. In its folded position, the handle biases a pair of knobs inwardly to prevent actuation of the trigger, while a portion of the trigger engages the firing pin to prevent movement of the firing pin. In the stored condition of the handgun, the firing pin is uncocked and is unable to be moved into a cocked position. The locking member has a guide portion which is slidable within a bore containing the firing pin and its biasing spring. The guide portion acts as an abutment and a guide for the rear end of the spring. In one embodiment of the invention, the locking member is cammed inwardly by the handle as the handle is unfolded, to automatically cock the firing pin spring.

Abstract: A destructive device for the destruction of equipment such as machines, tanks, and tank gun barrels for example, includes a casing, an alumino-thermic mixture carried therein, and an ignition fuse. The mixture is arranged such that, upon ignition, a heat-generating interreaction is produced for a certain reaction period. The casing is arranged to resist being carbonized by the heat generated by such reaction only for a period substantially commensurate with the reaction period. Consequently, the device may be significantly reduced in size and weight. The casing may comprise a low heat-conductive paper material which also serves to maximize the shock resistibility of the device.
