Abstract: A recoil pad for attachment to a firearm buttstock of the type having a retaining sleeve (14) and an end wall (16) which communicate to form a unitary boot. The sleeve (14) and wall (16) are constructed of similar density foam material, so as to absorb recoil upon the discharge of the firearm. The predetermined exterior dimension of the unitary boot is substantially larger than the dimension of rifle buttstock (12). This increased area allows the pad to disperse recoil impact more effectively. In addition, the retaining sleeve (14) may contain two, or more, sets of corresponding integrated incisions (22,24,26) which define earplug excisions (20).

Abstract: A dipole magnet is placed in a sabot of an explosive projectile. The magnet is arranged and configured within the interior surface of the sabot--such that when the sabot is placed over the casing of the projectile, the majority of the magnetic flux tends to take a path through the projectile casing and between two sensing coils located within the fuze and within the projectile. The first sensing coil forms a larger circle which encompasses the aft end or outer diameter of the projectile which is made up of ferrous materials. The second sensing coil forms a smaller concentric circle (relative to the first sensing coil) and is situated inside the inner diameter of the after end of the projectile, thus encompassing no ferrous metal. The majority of the flux from the magnet enters the ferrous projectile casing, travels through the casing, and exits primarily between the two coils on a continuous path back to the magnet.

Abstract: In a broad-area defense mine, the inclination under which an active member can rise or can be fired from an ambush position can be varied with the aid of at least one adjusting member between the positioning frame and a mounting or support for the active member which, in turn, are connected by way of a universal joint. In this arrangement, the mine, in the same way and with equal reliability as heretofore, combats a target within a specific area, but it is possible by means of this device to defend a substantially larger zone: the mine is transported, within the larger zone, to the "correct" site.

Abstract: A munitions launcher comprising a plurality of ejector assemblies each suitable for receiving a munition, and a base made of thermoplastic material molded over a portion of the periphery of the various ejector assemblies and over the rear thereof.

Abstract: A trap for receiving a projectile travelling along a substantially horizontal axis of travel at high velocity includes a pair of side walls, and primary, secondary and tertiary deflecting plates. The primary plate obliquely intersects the axis of travel of the projectile to downwardly deflect the projectile or particles thereof to approximately a second axis of travel. The secondary plate obliquely intersects the second axis of travel to further downwardly deflect the projectile or particles thereof to approximately a third axis of travel. The tertiary pate obliquely intersects the third axis of travel to further downwardly deflect the projectile or particles thereof to approximately a fourth axis of travel. Each deflection shows particle velocity. A bottom surface extends below the plates so that the plates, the sides and the bottom surface define a rectangular mouth for receiving the projectile and a chamber for containing the projectile or particles thereof.

Abstract: A safety mechanism for a firearm to prevent the firearm from firing except when the trigger has been moved to a predetermined position. The mechanism includes a plunger and a blocker. The blocker is movably mounted to the slide at a position in front of a striker to prevent the striker from moving forward to strike a cartridge. The plunger is movably mounted to a portion of the frame and is adapted to be moved by the trigger. The plunger, in turn, is adapted to move the blocker to allow a clear path for the striker to move forward to strike a cartridge.

A locking sleeve concentrically surrounding the breech block and axially slidable relative thereto to a limited degree, is divided at its front end by a plurality of longitudinal slots into a plurality of spring tongues and carries at the free, front end of each spring tongue a locking element formed in one piece therewith and in the form of an annular segment. Each locking element has a radially outwardly directed cone segment bearing on the locking shoulder in a locking position and having on its front end a radially inwardly directed cone segment with which it bears on a spreading cone arranged in the vicinity of the front end of the breech block.

Abstract: An endothermic cooler (10) for electronic components (16) in, for example, a missile (12) includes an enclosure (14) having a thermally conductive coupling to the electronic component. A source of water in a first compartment (28) is segregated from salts in a second compartment (30). The salts are capable of providing an endothermic reaction when mixed in a water solution. The two compartments are segregated from one another by a membrane or conduit (32). The membrane is pierced by a spike (34-2 or 34-3) through an actuating mechanism (36) and the conduit is opened by a valve (34-4). Formation of the solution provides cooling for conduction of heat from the electronic component through a thermally conductive plate (24) and its fins (26).

Abstract: Intelligent hard-target weapons provide a real-time estimation of a medium as the weapon is penetrating through it. Input signals are provided by an accelerometer used as a primary sensor. On-line concurrent processing of the data of a specific length facilitates a few different modes of feature extraction. The processor provides a robust, real-time decision making for the fuze utilizing sensor signals (accelerometer data). The feature sets utilized include (1) amplitude profiles of the signals, (2) their derivative profiles, and (3), the measure of their abrupt changes. The purpose is to provide for detonation at the proper point as the high-speed penetrator passes through various layers such as concrete, steel, dirt, sand, etc. on its way to a valuable buried target. Real-time decision making is provided for the fuze utilizing accelerometer data.

Abstract: A system and process for neutralizing unexploded ordinances and clearing explosive infested areas such that maneuvers can be both readily and confidently continued without significant delay is disclosed. The system clears such unexploded ordnances infested areas by initially spraying the explosive infested area with a cryogenic liquid to supercool the unexploded ordinances and reduce an output voltage of a detonator of the unexploded ordinances thereby rendering the unexploded ordinances inert, gathering the now unexploded ordinances and submerging the inert unexploded ordinances in a tank containing the same or similar cryogenic liquid so that the unexploded ordinances are maintained in a supercooled and inert state to allow for disposal.

Abstract: A method for producing a stabilized area by positioning a plurality of heat transfer tubes on or below the surface of the stabilized area and flowing a coolant through the tubes to maintain a stabilized area in a frozen condition. Water may also be frozen over the stabilized area.

Abstract: Vehicles that are frequently operated in "off road" conditions are normally equipped with a means by which some form of oscillation is provided to accommodate the uneven terrain over which it traverses. In some instances, the stability of the vehicle is inadequate while in other instances the stability is acceptable; however, the service life of the particular design is in question. The axle suspension 10 of the present invention is mounted to the vehicle frame 12 in a manner whereby the various types of forces encountered during the operation of the vehicle are directed to specific areas of the mounting. Being so directed, the mounting members 38 and 52, utilized in these specific areas of mounting, may be selected to best accommodate the type of loading that will be applied in that area.

Abstract: A low profile chemical biological air filter, comprising a frame having a rst end for attachment to a mask and having an upwardly facing surface defining an inlet for the filter. The frame has a length sufficient to space first and second filters from the inlet to the attachment first end and a width sufficient to enclose the two filters. Its thickness is no greater than that necessary to contain only one of the two filters to minimize the thickness of the frame by placing the two filters side by side. The filters include a HEPA filter for removing particulate material from the air and a Whetlerized charcoal filter bed for secondary filtering of the air. The HEPA filter is supported in the frame at the inlet as is the charcoal filter bed along with a fines filter for protecting from dust which may be dislodged from the charcoal filter bed.
