Abstract:
An weapon system comprising: a plurality of barrels, wherein the barrels are disposed coaxially around a main shaft and wherein the barrels are held in place by at least one barrel rack; and a plurality of intermeshing, counter rotating cylinders, wherein the cylinders include a central hole for the main shaft or a lower shaft and a plurality of coaxial half-holes disposed around the central hole at the edge of the cylindrical shape to form a chamber when the cylinders mesh. An ammunition belt comprising: a first and second ammunition case, wherein each ammunition case comprises: a casing having a first and second end, wherein the first end is adapted to receive and hold a primer and the second end is adapted to receive and hold propellant and a projectile, wherein the first ammunition case is attached to the second ammunition case.
Abstract:
A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.
Abstract:
A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, a fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the projectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner. The external geometry of the projectile also is configured so that the projectile tumbles when launched and follows a more predictable, repeatable and accurate path in flight.
Abstract:
An open chamber gas powered tool and gas generating charge for the tool. The charge has a hollow open-ended plastic jacket of uniform noncircular cross-section from end to end containing a propellant, such as nitrocellulose, which may be electrically ignited through an open end of the jacket by a spark, hot wire or the like or ignited by detonation of a dab of priming compound contained within a recess in one end of the jacket. The tool has an open chamber breech mechanism including a cylinder containing a firing chamber opening through the cylinder circumference for transporting charges to firing position wherein the chamber is closed by the breech frame, a trigger actuated firing means for firing the charges in firing position, and operating means powered by the gas generated by each fired charge for performing a work function.The particular tool described is a fastener driving tool having an electrical firing circuit which is conditioned for operation to fire charges by pressing the tool against a workpiece, and a plunger which is propelled through a working stroke by the pressurized gas generated by the fired charges to drive fasteners, such as nails or studs, into the workpiece. The invention also provides a novel method of fabricating and packaging the charges in a magazine with the charges fixed to a web or band for feeding the charges to the tool.
Abstract:
Apparatus for projecting bullet shaped additive materials into molten steel. The apparatus has two hoppers for holding the bullet-shaped additive materials and delivering them successively. A pair of rotary feeders having spaced elongated grooves receive the materials supplied from the hoppers and are rotated intermittently a distance corresponding to the pitch of the elongated grooves through use of a Geneva gear mechanism. A gas controlling device connected to a source of gas under pressure controls the supply of gas synchronously with the rotating motion of the rotary feeders to supply the gas to a pair of projectile guiding pipes which shoot the bullet shaped additive materials into a molten steel bath.
