摘要： An ammunition ''''cook-off'''' sensing and prevention system which is incorporated within a Gatling-type gun and therein indexes the gun barrels so that an ammunition round always is in position under an infra-red temperature sensor at the end of a firing cycle. If imminent ''''cook-off'''' of the round is indicated by the temperature sensor the gun is cycled at low speed until the heated ammunition rounds are removed from the high heat transfer area behind the gun barrels and replaced with cool rounds from the ammunition chute. If then necessary the cycle can be repeated. In this manner an extremely dangerous aspect of the Gatling-type gun is removed.

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 heater for warming the firing mechanism of a firearm and the hands of the user. One embodiment of the heater includes structure similar to well known hand warmers having fuel suspended adjacent a heater element which includes a catalytic substance to support combustion of the fuel vapors. The heater is positioned between the stock and the firing mechanism of the firearm and is adaptable to existing firearms. An alternate embodiment of the heater includes an electric heater element which radiates heat as electric current passes therethrough. A battery is included which is suitably coupled to the electric heater to force electric current therethrough.

摘要： An improved automatic pistol is provided with a lever mechanism which causes operation as a burst-firing arm in a safe and reliable manner. This is achieved by forming the disconnector, which releases the sear, with a chamfered and bent end, opposite to the end engaging said sear, in order to co-operate with a trigger bar which has two degrees of freedom in the usual repeating operation, and which is connected in an articulated manner to the pistol trigger. Through a 90.degree. rotation of a selector member, a should on the trigger bar allows the trigger bar only one degree of freedom thus causing the disconnector, which is pivotedly mounted on the reciprocating breech mechanism, to enter into a tangential, instead of perpendicular contact through its bent and chamfered end with the trigger bar. Thus, the disconnector enables continuous firing of the pistol as long as the trigger remains is pressed. The breech mechanism is provided with a number of air intakes and is preferably of frusto-pyramidal shape for cooling the piston barrel.
