Abstract: A front sight for handguns having side vanes for shading the sighting surface from undesirable reflections, and providing ramps to prevent the sight from snagging when used with a holster.

Abstract: Acoustic emission monitoring is a non-destructive testing technique that ects ultra-high frequency sound that stressed metal emits. In straightening a gun tube the workpiece is at first under no stress, is elastically deformed (with total springback when pressure is released), is plastically deformed (with some springback upon release of pressure), or it cracks under too great a pressure. Each of these stages produces a distinctly different type of acoustic emission. By listening to the workpiece during the pressing operation the operator can be alerted as to the stage the workpiece is in and he can adjust his operation accordingly.

Abstract: The process of converting FS smoke agent (a mixture of sulfur trioxide and hlorosulfonic acid) to sulfamic acid and ammonium chloride comprising the steps of dissolving the FS smoke agent in an organic solvent solution to obtain a solvation product, subjecting the solvation product to ammonia gas to obtain a sulfamic acid ammonium chloride mix, and separating and purifying the mix into sulfamic acid and ammonium chloride.

Abstract: A turnbuckle ratchet tightening tool which is used in rapidly tightening and loosening barge turnbuckles used with lashing lines to lash a plurality of barges together. The tool has an extendable overcenter lock holder that fits over the turnbuckle that is resting on roller supports. The turnbuckle carrier body is free to rotate. A foot operated lever is ratchet connected to an enlarged actuator whose teeth engage the teeth on the turnbuckle carrier body. In this manner, downward movement of the foot operated lever rotates the actuator which in turn rotates the turnbuckle carrier body in its holder.

Abstract: An apparatus capable of stressing test specimens to relatively high stres at an ultra fast rise time, and unstress at ultra fast decay time. System components include a hydraulic pumping unit, a gas-liquid accumulator, a pressure loading valve, an intensifier, a pressure vessel, a trigger mechanism, a pressure unloading valve, a surge tank, and system controls. To increase system operating response, the discharge port of the accumulator is connected directly to the inlet port of the loading valve. An exit port of the loading valve mounts directly to the inlet low pressure port of the intensifier. The high pressure outlet port of the intensifier mounts directly to the bottom inlet end of the pressure vessel, and the inlet port of the unloading valve mounts directly to a second exit port of the loading valve. The pressure vessel chamber and the intensifier's high pressure chamber are pre-filled as a closed system, with a low compressible fluid.

Abstract: This invention pertains to an obturator system used in large caliber weap, such as cannons, for the purpose of preventing high pressure and temperature gases from propellant charges to escape rearward through the breech. The sealing system consists of a spindle having a mushroom shaped head integral with a shaft portion, a metallic seal ring, and a disc spring. The shaft of the spindle passes through the breechblock such that the conical wedging surface of the mushroom head contacts the interior conical surface of the seal ring. The external conical surface of the metallic seal ring contacts the chamber gas check seat, and the base of the seal ring contacts the top surface of the disc spring which in turn rests against the front face of the breechblock.

Abstract: A self aligning expansible sabot for projection from worm gun tubes without alloting of the sabot pedals due to misalignment and vibration. The sabot consists of three segments pinned together so they move radially in an expanding manner in the worm gun tube without loss of axial alignment. The connection pins allow normal discard of the sabot segments without excessive binding and without independent rotation.

Abstract: An aiming post light for artillery and mortar operations at night wherein an ordinary GI flashlight may be used, without modification, as a post light when mounted on a support and wherein its original ordinary lightbulb is replaced with a novel bulb of same base outer configuration in which the bulb has encapsulated solid state circuitry to provide a blinking and/or steady light emitting diode (LED) as the light source. Depending upon the particular LED and circuitry selected, the light may be continuous or intermittent and may be a selected color. In one embodiment several options are available when using a single bulb.

Abstract: A tool for extending the barrel of a revolver crane and for checking the alignment of the crane barrel and cylinder locking aperture in a revolver frame. The crane barrel is inserted over an alignment stud and an adjustable stylus is threaded into contact with the crane barrel near its end. Rotation of the crane barrel causes a groove to be worn on the outer surface of the crane barrel and thus cause the barrel to elongate to its desired length. Additionally, the alignment stud may be used to align the crane barrel to the revolver cylinder locking aperture.

Abstract: A sight base bridge for an automatic pistol having relative movement between its slide and barrel, said bridge permitting the mounting of sights directly to the pistol barrel, thus eliminating inaccuracy caused by tolerances between the barrel and slide formerly having the sights thereon. A similar mounting system can be used for attachment of silencers and compensators.

Abstract: Light emitting diodes (LED) are used in conjunction with phototransistors determine the liquid-solid state of a 0.030-0.040 inch film of trinitrotoluene (TNT). Liquid TNT is collected on the surface of a rotating drum, and is subsequently cooled to a solid film and removed by a "flaking" knife. The emitted beam from the LED is absorbed when the TNT is in the solid state and transmitted to and reflected from the drum surface when the TNT is in the liquid state. The relative intensity of the reflected beam is a measure of the state of the TNT.

Abstract: An automatic loading device consisting of a magazine of rounds of ammunit, a tray and rammer assembly to receive a round from the magazine as the gun tube recoils from firing a previous round, means responsive to counter recoil movement of the gun tube for moving the tray into position for loading a round into the gun chamber, cable means for releasing a rammer mechanism to exert forward movement against the round to move it forward into the gun chamber and close the gun breech. A fluid drive means retracts the rammer to cocked position during recoil to enable it to operate (move the round forward) during counter recoil of the gun tube.

Abstract: Tear gas or CS (o-Chlorobenzalmalononitrile) has two nitrile functional gps which, when removed, effects the chemical conversion of bulk CS to o-chlorostyrene. This involves a first step, an acid or base catalyzed hydrolysis of CS to o-chlorocinnamic acid. Thereafter a second reaction is the decarboxylation of the intermediate product to give o-chlorostyrene.CS is reacted with 70% sulfuric acid at 120.degree. C., producing ammonium sulfate and orth-ochlorocinnamic acid (the intermediate product). This intermediate product is separated and thermally decarboxylated at 270.degree. C. (with a catalytic amount of soda lime and copper powder) to ortho-chlorostyrene.

Abstract: A projectile pallet hand truck is provided for one man mechanical operation in moving heavy loads. Curved rocker arms on wheels facilitate pallet positioning, and an extensible lever is used in transferring the load center of gravity over tricycle wheels for movement. Extra handles are provided for easier operator movement when the truck is in loaded position.

Abstract: A tire disintegrator having rows of abrasive counterrotating wheels between and over which defective tires are passed to be ground into particles or residue for disposal or recycling into new tire products and road resurfacing materials.

Abstract: An aiming post light for artillery and mortar operations at night wherein an ordinary GI flashlight is converted with solid state circuitry to use a blinking light emitting diode (LED) as a light source, enabling ordinary flashlight batteries to last for months of constant use instead of the few hours life in use with previous post lights.
