  • Patent number: 8176849
    Abstract: A fragmentation warhead includes a cylindrical body, and an explosive charge disposed within the innermost part of the warhead body. Upon detonation of the explosive charge, the warhead body is ultimately caused to shear and break into fragments with controlled sizes, shapes. Metallurgical composition of the warhead body can be used to influence the size of fragments ultimately generated when the warhead breaks apart through detonation, since the size and positioning of fragments in the warhead body is preselected. Fabrication of explosive fragmentation ammunition with preformed fragment tungsten alloy fragmenting shells of complex shapes and small and medium calibers is provided in this invention. According to an embodiment of this invention, fabrication begins with “green” tungsten alloy fragment pellets of a given, full strength, enwrapped in a green lower strength matrix alloy.

  • Patent number: 8161884
    Abstract: A selective fragmentation pattern of explosive material is applied to a surface of a munition. None, some, or all of the explosive material in the selective fragmentation pattern may be detonated, selectively stamping the surface of the munition with the detonated explosive material. The portion of the selective fragmentation pattern selected for ignition is determined by lethality requirements of a target of the munition. Upon detonation of the munition, fragments are formed based on the selected portion of the selective fragmentation pattern. Consequently, igniting all, some, or none of the selective fragmentation pattern may vary lethality of a munition and one munition may be used for a wide range of lethality.

  • Patent number: 8115149
    Abstract: A Hybrid Projectile is provided for delivering an explosive payload to a target wherein the Hybrid Projectile may be steered in flight using relatively inexpensive means. The Hybrid Projectile is exteriorly configured in the same physical exterior configuration of conventional ammunition of various standard types so it can be launched in conventional manner from the same weapon systems. However, internal features allow the Hybrid Projectile to be transformed in flight from a command signal to deploy wings and fins, and in some projectiles to telescope open to deploy such wings and fins. An inexpensive televisual means is activated in the fore region of the round which through RF uplink command can be used to select a path, while motors on the wings can then be used to more precisely glide the projectile to a target, or otherwise to abort the target run.

  • Patent number: 8109213
    Abstract: A single multipurpose ammunition projectile/warhead is provided, which has the capability of clearing a variety of different types of hardened targets. The single projectile of this invention may be used for breaching steel reinforced concrete walls; may be used against light armor targets; may be used for defeating bunkers; and may also be used for antipersonnel applications. Huge savings in time, money, inventory and logistics are realized through utilizing only this one multipurpose ammunition against all these types of targets. This multipurpose projectile, among other superb capabilities, is able to puncture an eight inch double steel reinforced concrete wall timed to then have its warhead explode into fragments. This allows fragmentation in a more effective, nearly ideal direction. The projectile warhead of made of extremely thick walled 300M steel; with the projectile center of gravity to be located equidistant between a pair of bourrelets, for increased stability.

  • Patent number: 8091478
    Abstract: A target discrimination system monitors an acceleration switch signal to determine an impact of a projectile on a target. During a sample period of approximately 1.0 milliseconds, the system repeatedly samples the acceleration switch signal, compares the sampled acceleration sensor signal with a reference voltage, and sets a comparator data output to logic one if the sampled signal exceeds the reference voltage. Otherwise, the comparator data output is set to logic zero. The system counts the instances that comparator data output equals logic one during the sample period and executes a selected delay. The selected delay is approximately 50 milliseconds if the counted number of instances exceeds a predetermined threshold of approximately two-thirds of the samples and, otherwise, the selected delay is approximately 10 milliseconds. The selective delay enables target discrimination and selective detonation of a projectile.

  • Patent number: 8069606
    Abstract: This tool makes it possible to more conveniently handle the “selector” element on a conventional M16/M4 family weapon when the selector must be removed or reinserted. As will be appreciated by those in the gun repair trade, in the disassembly or reassembly of such weapons the handling of the selector element is a tricky and painstaking activity. This disclosed tool handily is an assist in such activities. The tool is inserted in the opening in the receiver of the selector element and rotated. An offset circular cam means on the tool when rotated will handily depress the detent element (which necessarily must be done and it also has a spring beneath it). A bumper end cap at the distal end of the tool will carefully engage the selector element to gently push on it if needed (or in the reverse operation for the tool to be gently backed away there from as the selector is repositioned into the weapon).

  • Patent number: 8061275
    Abstract: A fragmentation warhead includes a cylindrical body, and an explosive charge disposed within the innermost part of the warhead body. Upon detonation of the explosive charge, the warhead body is ultimately caused to shear and break into fragments with controlled sizes, shapes. This invention enables target-adaptable fragmentation output based selectively controlling the size of preformed fragments ejected. Preformed tungsten alloy fragments of a first “small” size “A” are sintered to be joined into a plurality of larger size fragments “B”, using a tungsten alloy matrix. The B fragments are then joined into a desired shell shape and thickness and sintered into a fragmenting shell body using a different tungsten alloy matrix with bonds of melting point considerably lower than amongst the A fragment bonds.

  • Patent number: 8063348
    Abstract: A system for detection of optical type devices being used by an enemy sniper subject without alerting the enemy is shown. A coherent laser beam of a wave length in the visible color range, is sent along an axis and passing through a beam splitter device. A detection means is arranged to generate a signal when it detects retro-reflections from the target optical devices or subject including clutter reflections in a 180 degree direction relative to axis. The detection means is coaxially mounted with the source of illumination with a second detection means off axis therefrom to generate a second detection signal when it detects clutter reflections from the target optical devices or subject. A comparator means forms a difference signal between the retro-reflected detection signal and the second detection signal and indicates when the difference signal exceeds a predetermined threshold.

  • Patent number: 8006423
    Abstract: An improved magazine follower for use in existing magazines such as a 30 round magazine comprises a follower plate, a base plate, and a spring. The follower plate comprises a top plate, a convex follower leg, and a concave follower leg. The external shapes of the top plate, the convex follower leg, and the concave follower leg mirror the interior profile of the magazine, constraining the motion of the follower plate to a well-defined path within the magazine. The method of attaching the spring to the follower plate and the base plate in addition to the shape of the spring keeps the spring from “wobbling” or moving off a vertical axis of the spring as rounds of ammunition are loaded or dispensed. Consequently, the present system reduces binding or jams within the magazine, improving performance and life of the magazine follower.

  • Patent number: 7886667
    Abstract: A warhead includes a body, a patterned liner made of plastic, and an explosive charge disposed within the liner. The liner pattern is formed of gaps and liner elements. The explosive charge includes a first set of sections that are disposed adjacent to the liner gaps and a second set of sections that are disposed adjacent to the liner elements. Upon detonation of the explosive charge and because of the temporal delay in transmitting the detonation energy between these two sets of sections, the warhead body is caused to shear and break into fragments with controlled size. The use of plastic as the liner material also provides a welcome safety feature for this warhead. In the event of unwanted heat ignition, the plastic (which is also low melt temperature material), would melt to seal the explosive and would also flow. Because of the plastic, neither sudden pressure nor heat/ignition inside the round, would therefore be as catastrophic.
