Abstract: A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.

Abstract: The invention provides an ammunition carrier for retaining ammunition. The ammunition carrier includes a stationary carrier body portion disposed about a space in which to retain the ammunition; and a rotating carrier body portion disposed about the space and pivotally. attached to the stationary carrier body portion. The stationary carrier body portion and the rotating carrier body portion collectively form a cover assembly to secure the ammunition. The ammunition carrier further includes a locking mechanism, the locking mechanism pivotally attached to the rotating carrier body portion, the locking mechanism (1) engageable, in an engaged position, with the stationary carrier body portion so as to prevent rotation of the rotating carrier body portion relative to the stationary carrier body portion; and (2) disengageable, in a disengaged position, with the stationary carrier body portion so as to allow rotation of the rotating carrier body portion relative to the stationary carrier body portion.

Abstract: A method and system may include receiving a sample gas from an ambient environment on a first surface of a selective isolation device within an inlet assembly, dispersing the sample gas in substantially a first direction along the first surface, and circulating a carrier gas through a main assembly coupled to the inlet assembly, the main assembly defining a carrier gas environment. The method and system also may include selectively passing analytes from the sample gas through the selective isolation device to a second surface of the selective isolation device, the selective isolation device separating the ambient environment from the carrier gas environment, dispersing the carrier gas in substantially a second direction along the second surface, and obtaining the analytes in the carrier gas from the second surface.

Abstract: The invention provides for a transport system and method of using the transport system. The transport system may include a transport track; and a platform assembly that transports along the transport track, the platform assembly including (1) a cargo platform; and (2) a pair of drive pinion trucks mounted on opposing sides of the cargo platform, each drive pinion truck engaged with the transport track for movement along the transport track. The drive pinion trucks may be provided with a leveling system to provide leveling of the cargo platform during operation.

Abstract: Fire-resistant structural composites are comprised of a phenolic resin system, reinforcing fibers and alumina tri-hydrate. The composites may be formed into structural or load-bearing parts, and are particularly suited for applications requiring high strength and a high degree of fire-resistance, such as in the automotive, aircraft, or ship-building industry. Optionally, a siloxane modifier may be added to the resin system to improve the flexibility and impact resistance of the composite.

Abstract: A method of manufacturing a hollow section grid-stiffened panel comprises providing a tool (10) having a surface (12). The stiffened skin composite panel is preassembled comprising laminating a composite outer skin (14) on the surface, placing a separator outer layer (16) on the composite outer skin (14), and laminating a composite stiffener (20) on the mandrel (18), the mandrel being positioned on the separator layer (16), wherein the separator layer (16) separates the stiffener (20) and the mandrel (18) from the outer composite skin (14). The preassembled outer skin composite panel is cured on the tool. The separator layer (16) and mandrel (18) are removed from the preassembled stiffened skin composite panel. The stiffened skin composite panel is reassembled, comprising applying an adhesive between the composite outer skin (14) and the composite stiffener (20). The reassembled stiffener skin composite panel is cured on the tool to bond the stiffener skin to the outer skin.

Abstract: A non-lethal laser weapon having a base to which a number of lasers are mounted. The lasers include a first laser oriented to project a first laser beam in a first direction, and a second laser oriented to project a second laser beam generally in the first direction. The first laser beam and the second laser beam overlap at a first distance from the base, to thereby form separate first and second first-order illumination zones before the first distance, and a first second-order illumination zone beyond the first distance. Additional lasers may be included in one-, two-, and three-dimensional patterns to create additional illumination zones.

Abstract: A system and method for absorbing a recoil force in a weapon is provided. A recoil mechanism includes a housing that contains a hydraulic fluid and has an inner wall defining a first chamber and a second chamber within the housing. The inner wall has at least one orifice that connects the first and second chambers. A piston is slidably disposed within the first chamber of the housing. A shuttle valve is slidably disposed within the first chamber of the housing and has at least one orifice configured to align with the at least one orifice in the inner wall of the housing to define a fluid passageway between the first and second chambers. A shuttle valve control is operable to generate a magnetic field in response to an applied current to control the movement of the shuttle valve to thereby control the size of the fluid passageway between the first and second chambers.

Abstract: A friction restraint and latching assembly for a charge unit storage chamber defined by an elongated casing having an open end, and including a friction restraint bar of a length approximating that of the elongated casing, and supported at the periphery of the casing for axial and radial movement between a retracted position out of contact with charge units in the storage chamber and an engaged position in frictional contact with the charge units in the storage chamber and so that axial movement of the friction restraint bar toward the open end of the casing results in radial movement of the friction restraint bar to the engaged position. The friction restraint bare is biased yieldably to the engaged position.
