摘要： A T-joint having a two-part housing applicable to a pipe contains a member adapted to cut a hole in the pipe when acted upon by an explosive charge to provide a branch conduit from the pipe. The explosive charge is contained in a nut attachable to the housing and is ignited by a percussion cap. The bottom portion of the nut is provided with three concentric recesses, each one smaller than the preceding one. The first recess holds the charge, the second recess holds a breech member for the percussion cap, and the third recess holds an anvil for firing the cap.

摘要： A propellent charge igniter for caseless cartridges of separately loaded ammunition. The igniter has an ignition chain which includes a secondary charge adjoining a main charge made up of powder pipes or tubes. The secondary charge is disposed in pierceable bag material. A booster charge is disposed in a cartridge case which is mounted in the movable breech block. A combustible projectile is mounted in the cartridge case, and is adapted to be ejected from the cartridge case by the gases generated by the booster charge to pierce the bag material and ignite the secondary charge.

摘要： 1,222,439. Percussion firing mechanism. F. A. DONNER. 19 April, 1968 [20 April, 1967], No. 18707/68. Heading F3C. A percussion device for a mortar comprises a projectile receiving chamber I 1 , a striker rod 10 and striking mechanism, the rod being slidable between a firing position and a rest position and having one end movable within a passage (formed in the cap 9) to project therefrom into the chamber in the firing position, and carries a sealing valve 11 for co-operation with a seat 12 formed round the axis of the said passage and facing the chamber, the rod having return means 14 co-operating therewith to urge the valve against the seat, the said one end of the rod being a loose fit within the passage and thereby substantially free from sliding friction along its sides during its sliding movement. As shown, the striking mechanism comprises a hammer 22 actuable by a spring, not shown, and returned by spring 15. In another embodiment (Figs. 2-4, not shown) the hammer is provided with a positive drive by means of an eccentric pin (17), the hammer 22 being loosely coupled to the striker rod 10 which has a rear tip (18) disposed between faces (20, 21) of the hammer.

摘要： An electrical generator for a self-contained electrically triggered weapon is provided which converts the reciprocating movement of a moving mechanical part of the weapon, e.g., a reciprocating breech member, into rotational movement of a generator rotor. A cam on the moving mechanical part engages in helical track to cause rotation thereof. This rotation is transmitted to the generator rotor through a gearing arrangement including a drive gear which drives the generator rotor during rotation of the track in a first direction, inertical forces providing for continued rotation of the generator rotor in the same direction during rotation of the track in the opposite direction.

摘要： A regenerative liquid propellant gun having structure which reacts to combustion pressure to dispense and regulate the flow of liquid propellant from an included reservoir as one parameter for obtaining a predetermined pressure/time curve of gun chamber pressure. A first coaxial pumping piston is a differential area pressure piston operating between the combustion chamber and the primary propellant reservoir. A second coaxial piston in a bore in the first piston opens and closes injection ducts running through the pumping piston from the primary reservoir to the bore to interdict flow of propellant to the combustion chamber as a result of relative motion of the two pistons as one or both move responsive to propellant combustion pressure. The second piston may also be a differential area piston operating between the combustion chamber and a second reservoir which may also dispense propellant to the combustion chamber or may be a part of a separate hydraulic system dedicated to hydraulic control of the second piston. The disclosure includes several alternative arrangements for control of the relative movement between the pistons.
