Abstract: A backup mechanism for a fuze includes a plate having a slot therein which is freed up during the arming of the firing pin screw. A weight link having a pair of legs spaced along the slot is mounted for movement in the slot. A trip link is pivotally mounted to the plate and has a first leg for frictional engagement against the side of the first weight link leg. The second leg of the trip link is biased for rotation by a leaf spring. Another leaf spring engages against the second leg of the weight link for urging it in a movement direction along the slot. Friction between the first legs of the trip and weight links and/or the upward pull force of the ribbon hold the weight link in an initial position after fuze arming. When exposed to inertia, and/or the absence of upward ribbon pull force the weight link moves. This causes disengagement between its first leg and the first leg of the trip link. The spring rotates the strip link so that its first leg now pushes the weight link along the slot.

Abstract: A device and method is disclosed for detecting elemental ions by colliding a beam of the elemental ions with a beam of collision partners having an opposite charge to generate element specific radiation. The radiation whose wavelength is specific to the element is filtered and detected as a measure of the elemental ion. In one case using energy matched collision exchange partners, metal ions of an opposite charge are used as collision partners.

Abstract: The invention concerns an EM Launcher wherein each projectile has an insuor which, when subjected to a breakdown voltage, allows current conduction through the EM rails and the projectile for acceleration thereof. The insulator thus provides a disposable switch for a rapid fire EM launcher, negating the necessity of electrical (inductor circuit) charging or mechanical (breech) recycling.A key element in the invention is the replacing of a repetitively operated external switch with a plurality of single-shot, disposable switches. Better performance can be obtained from a single-shot switch (i.e., lower inductance, lower on-state voltage drop) because the compromises required of a repetitive switch to enable it to recover its voltage holdoff are not necessary.

Abstract: The invention is an improved device for sectoring screw threads on gun tu. The invention makes it possible to produce a plurality of sectors of screw threads on gun tubes instead of producing a single sector during each operation. The sectoring procedure is a machining process where portions of the screw thread are removed. The device for sectoring screw threads or gun tubes consists of a slide base assembly for positioning and holding other sub-assemblies of the device; a base plate with uprights for attaching to a machine tool bed or table; a clapper box head; and guide bars to provide for the exact positioning and longitudinal movement of the clapper box head.

Abstract: A modular armor support employs parallel bars affixed to a substrate for porting modular armor panels a predetermined distance from the substrate. In one embodiment, the parallel bars are beams or rails affixed to the substrate and having abutment surfaces for supporting the modular armor panels with their edges in close abutment. The armor modules are affixed by bolts passing through holes in the armor modules and engaging threaded holes in bars extending between the beams or rails. In a further embodiment, the parallel bars are in the form of corrugated straps with lower portions bolted to bosses in the substrate and upper portions adjacent the modular armor panels. The lower and upper portions are connected by angled portions.

Abstract: An electrically detonated fuse for a grenade is shown, used either as a b up system for the usual mechanical detonator, or independently as the sole arming and detonating means. The invention is considered more accurate and dependable than a mechanical system, which is aimed at the objective of reducing the amount of grenade duds, the dangerous phenomenon of still live grenades unexploded upon impact creating a hazardous situation for military and other personnel. The invention uses the ordinary twisting action of the currently used inflated ribbon which is extended from the grenade while it is in flight, to generate an electromotive force signal. An electrically activated detonator is installed next to the grenade's main charge, for blowing the device when the electrical detonator is switched on. A large surge of power is fed to the electrical detonator by the closing of an electrical impact fuse, when the grenade physically impacts a target.

Abstract: A firing mechanism for a weapon having a receiver with a chamber for a caidge comprises a bolt and piston which are separately movable toward and away from the chamber and which are engaged with each other for displacing and rotating the bolt into a locked firing position. A buffer is also movable in the receiver and can strike the rear end of the piston. The piston carries a firing pin which can thus be driven into the primer of a cartridge in the chamber. Three sears are provided. Two of the sears are for engaging the piston, one sear for holding the piston in a position with its firing pin away from the cartridge but with the bolt against the chamber and in its locked position. The other sear for the piston holds the piston with the bolt in a position away from the chamber. This is for open bolt operation. A third sear is provided for engaging the buffer for closed bolt operation.

Abstract: A 75-liter plexiglass chamber has been constructed to simultaneously expose 0 rats to a test vapor. Each rat is confined in a small plexiglass plethysmographic box attached to the large chamber. During exposure, the respiration rate, tidal volume, body temperature, pH, and blood gases are measured. A sample of the blood may be used to measure the amount of a volatile test chemical reaching the blood or to measure blood pCO.sub.2 pO.sub.2, and pH. This apparatus optimizes animal usage by permitting many sequential measurements on a minimum number of test animals. Since the animals are exposed simultaneously, the interanimal variations in exposure are minimized.

Abstract: This invention provides a reliable, operationally simple means of producing suspension of dust or gas at the end wall of a shock tube prior to the arrival of the incident shock wave. It consists of a cylindrically shaped sample chamber having diaphragms at both ends and a cylinder-and-piston apparatus for driving a powder or other sample from the inside of the chamber into the shock tube.

Abstract: A circuit having indication lights for demonstrating when a flash trigger pulse has been fed to an X-ray photographic system or the like, is provided. The invention is especially useful in noting that a false triggering pulse, or prefire had inadvertently happened to a flash unit of an X-ray system before it was intended to be used, thus triggering it to photograph, ruining its film. This invention is also useful in that it marks which in a plurality of systems had been the one that had been falsely triggered, and additionally useful in marking that all of the said units had been properly triggered when a true pulsing had been engaged for all units, or of marking which unit had failed to fire.

It is made entirely of plastic materials; there is no metal which may fragment.

Abstract: A system and method for wide-area mine clearance employs a plurality of f-containing plastic containers disposed a horizontal distance apart which permits an overlap between adjacent aerosol clouds formed therefrom when explosive bursters are simultaneously detonated within each container. At least one detonation charge is exploded within one of the aerosol clouds following a predetermined time delay for detonating the line of overlapping clouds whereby a line of ground surface is exposed to a fuel-air explosion capable of detonating susceptible mines therein. The distance between adjacent containers and the height each container is suspended above the ground is related to the weight of the liquid fuel contained in each container. In the preferred embodiment, each plastic container is suspended from a tripod having a hook or other means for permitting attachment and detachment of a crane hook whereby the tripod may be positioned over uncleared ground from a location well within cleared ground.

Abstract: A magazine for a weapon having a barrel extending in a firing direction iudes a cartridge storage drum which stores a multiplicity of cartridges in a spiral path with a longitudinal axis of the cartridges lying perpendicularly to the firing direction. If the weapon is an automatic rifle, the storage drum can be mounted in or under the stock of the rifle. A guide made up of curved rods extends from the drum and defines a guide path along which the cartridges are fed and rotated from their respect to the firing direction. A feed box is connected to the end of the guide rods at a location remote from the drum for feeding the cartridges to a bolt and chamber area of the weapon. Along the guide path the cartridges engage each other at pivot points so that the cartridges are somewhat free to pivot within the confines of the guide rods but still push each other along the guide path. One or more followers are provided behind the last cartridge.

Abstract: The invention provides for precise control of the initial trajectory of the etals of a discarding sabot from a gun-launched, sabot-driven projectile, so as to eliminate or minimize unbalanced forces on the projectile and avoid disturbance of its flight path. To achieve this precision, a separate, symmetrically oriented hinging element between the sabot petals is used. The hinging element is structurally separate from any means by which the sabot is secured to the projectile or other ammunition components, so that its shape and location, and the material from which it is made, may be oriented specifically to this function. The sabot petals are furthermore contoured with relief cuts so that as the petals rotate open about the projectile, the stress on the hinging element becomes sufficient to rupture it only after the petals have opened sufficiently to clear the projectile.
