    摘要： An internal pressure relieving device for anti-armour ammunition. The device is mainly adapted for use with barrel-loaded ammunition, that is a naked round including a cartridge case, which normally would be located in its packaging. A plurality of slot formed openings have been cut out through a wall of the cartridge case and the openings have been sealed by inserts of polymeric plastic introduced with a tight fit into each opening. Hence, by the characteristics of the plastic material, the inserts can be configured to open up at a predetermined level of temperature. Alternatively, the inserts open up at a predetermined level of pressure in the cartridge case.

    摘要： A FIRE CONTROL SYSTEM FOR AN AUTOMTIC FIREARM CAPABLE OF BEING MANUALLY SET TO SELECTIVELY PROVIDE AUTOMATIC CLOSED-BOLT OPERTION, AUTOMATIC OPEN-BOLT OPERATION AND SEMIAUTOMATIC CLOSED-BOLT OPERTION. THE FIREARM CAN BE SET TO THESE MODES OF OPERATION BY MOVING A MODE-SELECTOR KNOB LOCATED ON THE EXTERIOR OF THE FIREARM. THE KNOB MOVES A CAM WHICH COOPERATES WITH SEARS PARTS TO SET THE MODE OF OPERATION. A HEAT SENSING DEVICE IS POSITIONED IN THE BARREL OF THE FIREARM NEAR THE FIRING CHAMBER TO SENSE THE TEMPERTURE OF THE BARREL AND WHEN THIS TEMPERATURE REACHES A POINT AT WHICH COOK-OFF OF A CARTRIDGE IS INCIPIENT A MECHANISM IS ACTUATED TO AUTOMATICALLY SWITCH THE FIREARM TO ITS AUTOMATIC OPEN-BOLT MODE OF OPERATION. THE FIREARM IS CAPABLE OF FIRING CASELESS AMMUNITION.

    摘要： A weapon having a barrel cluster, having at least one, preferably multiple, weapon barrel(s) and having a bolt, and only one of the weapon barrels is oriented in alignment with the single bolt and interacts therewith for the purposes of firing. The barrel cluster has a front, muzzle-side barrel holder and has a rear, bolt-side barrel holder, and has, in a partial region, a control body with a control cam which is incorporated on the circumference. By way of said control cam, the barrel cluster can be adjusted as a whole and independently of the firing of the weapon. The control body is preferably electronically rotated, for which purpose a pin of the actuator engages into the control cam of the control body.

    摘要： A high velocity munition comprises a projectile, mounted on a cartridge case, that can be fired from an automatic cannon or weapon. During storage or transport an IM venting device included in the cartridge case prevents the propellant charge from firing the projectile, leaving the cartridge damaged, but intact upon premature ignition. The IM vent exhaust channel is filled with a solid fusible material that melts at a lower temperature than the ignition temperatures of the igniter (or primer) and the propellant charge of the projectile. At least one non-fusible, ruptureable member is included in the IM vent channel and positioned to provide structural integrity to the fusible material in the channel. Alternatively or in addition to the fusible material, a shape memory alloy ring surrounds the igniter (or primer) and separates from the cartridge when the cartridge reaches a temperature that causes auto-ignition.
