  • Patent number: 6050169
    Abstract: A fired rifle cartridge is resized in the cartridge neck area for reuse. A first die set is employed to compress the cartridge neck such that the inner surface of the neck fits a standard size bullet. A second die set is used to expand selected areas of the cartridge neck to snugly fit the firing chamber. The resultant ammunition round can be fired with a greater degree of accuracy than ammunition resized by prior art procedures, because the longitudinal axis of the cartridge neck coincides with the bore axis of the firearm.

  • Patent number: 5753851
    Abstract: The spinning mine has all of its projectiles concentrated in one small ar It is launched from a spring-loaded threaded screw launcher and acquires angular momentum as it ascends into the air from the launcher to a pre-determined detonation altitude. As the mine spins, the detector assembly on board detects the presence and location of potential targets and sends appropriate indicative signals to a microprocessor, also on board. The microprocessor determines therefrom the location of the largest target or the largest cluster of targets in the environment and triggers the detonation of the mine such that the projectiles are jettisoned in a conical pattern toward the largest target or the largest cluster of targets for a more efficient destruction of the targets.

  • Patent number: 5574245
    Abstract: A fragment-sealing bullet trap for rifle muzzle launched projectiles having a soft aluminum plug for decelerating and absorbing the softer components of rifle bullets, followed by a shock absorbing piston to mitigate the peak acceleration of the projectile due to bullet impact, in turn followed by a hardened steel anvil to safely capture any steel bullet components. Attached to the aft portion of the plug is an aluminum cap, containing a rubber gasket, which expands during bullet penetration, but rebounds due to its resiliency, tightly sealing off the bullet trap against the escape of bullet and plug fragments. The cap is designed to prevent the gasket from blowing out as a result of high bullet trap pressurization.

  • Patent number: 5545002
    Abstract: A stator vane mounting platform is disclosed which provides internal cooling chambers which facilitates the flow of cooling air through the chambers and thus, the cooling of the stator assembly. Baffles define an upstream chamber and a downstream cooling chamber between adjacent stator vanes so as to maximize the airflow and, consequently, the cooling effects of this airflow. The internal cooling chambers are defined by a thick wall and a relatively thin wall, the thin wall being in direct contact with the hot gases passing through the stator assembly. Mounting lugs and flanges are directly attached to the thicker wall so as to mount the stator assembly to the turbine engine structure and to accommodate all of the mechanical stresses encountered during the turbine engine operation.

  • Patent number: 5067409
    Abstract: A shaped charge for missiles which are provided for defeating armored vehicles in such a manner that the flight path of the missile is beside, below or above the target. The warhead is ignited at an instant when the missile is either beside, below or above a weakly armored portion of the target. The shaped charge is characterized by a hollow body (liner), which is surrounded by an explosive charge. To compensate for the velocity of the missile, the explosive charge is designed such that the charge axis forms an angle with the axis of the inner counter of the hollow body (liner), and such that sections in planes normal to the axis of the inner liner contour have circular or elliptic cross sections. The liner may be designed in a way that the axes of the inner and the outer contours can be translated with respect to each other and/or inclined by a small angle toward each other. Also the cone angles of the inner and outer contours of the liner may be different.

  • Patent number: 4333402
    Abstract: A projectile (1) containing particles of interference material is fired pneumatically from a launching tube (2). Compressed air, which is supplied to the launching tube and acts on the rear face of the projectile during firing, is conducted both to a loading chamber (19) wherein the air pressure is maintained even after the projectile has left the firing tube, and also via the loading chamber to an expansion chamber (20) in which, after a specific time-lag corresponding with a certain launch height on the trajectory of the projectile, an over-pressure builds up which causes the expansion of the chamber to be initiated with simultaneous expulsion of the interference material from the projectile. The compressed air may also be conducted to the chamber (10) in the projectile wherein the interference material is accommodated, tightly packed, in order to enhance the dispersion thereof.
