Abstract: An expandable plug or anchor having a diametrical hole in either the socket member or male member or both. The location of the hole or holes is such that unless the proper amount of relative movement between the socket member and male member necessary to properly expand the plug is effected, the hole or holes are blocked and a wire cannot be passed through the hole and be attached to the plug.

Abstract: 1. In combination with a vessel forming a rocket motor combustion chamber, a rubber-base liner having one surface firmly adhering to the chamber, the opposite surface of said rubber-base liner having a plurality of discrete powder grains partially embedded therein, each of said powder grains having a portion extending from said opposite surface of said rubber-base liner, and a propellant charge substantially filling the lined portion of said chamber, said propellant charge firmly adhering to said liner and enveloping each of said extending portions of said powder grains.

Abstract: A valve assembly for providing a measured amount of fluid under pressure from a bulk supply thereof. The bulk supply has a valved outlet which may be opened by a probe. The probe is slidably disposed in a valve housing which also contains a fluid measuring chamber. A valved outlet passage leads from the measuring chamber to an outlet adapted to receive a fluid line. The outlet passage and outlet are offset from the probe so that dispensed fluid does not pass through the probe or probe passage. The outlet passage valve is normally open but is closed when the probe is moved to open the bulk supply outlet valve. A rocking lever connects the probe and outlet passage valve to open and close the latter.

Abstract: A priming composition for use in ammunition, which priming composition contains as a frictionator and sensitizer ground metallic oxide particles, such as cupric oxide, in place of ground glass.

Abstract: A priming composition for use in ammunition, which priming composition contains as a frictionator and sensitizer ground zirconium oxide particles in place of glass.

Abstract: A one piece retaining member for use in a telescopic sight for imparting pivotal movement to an erector lens assembly. The erector lenses are housed in a tubular housing contained in the barrel of the sight. The retaining member includes means forming a pivot for the erector tube and means forming spring fingers for biasing the erector tube about the pivot.

Abstract: A pyrotechnic signal such as a flare, smoke signal, or the like, which is provided with a hollow plastic handle into which the pyrotechnic mass is telescopingly received. For storage, the pyrotechnic mass is positioned within the handle and for use the pyrotechnic mass is partially withdrawn from the handle. The handle may be rendered water-tight so that the signal can be used in marine environments and will float on water.

Abstract: 1. A composition for lining the combustion chamber of a rocket motor employing a solid propellant comprised of an epoxy resin, a copolymer of butadiene and acrylic acid, a curing agent, and between about 2.5 and about 30 per cent by weight of an inert inorganic filler selected from the group consisting of carbon, ferric oxide, titanium dioxide and mixtures thereof.

Abstract: Shot for use in ammunition with each shot pellet having six equally spaced, substantially flattened faces joined by spherical portions which can be randomly packed in a container with a density about 14 per cent greater than the packing density obtained with standard spherical shot of the same weight.

Abstract: A method and apparatus for grinding work pieces having internal chambers comprising loading blank work pieces onto respective ones of a plurality of mandrels provided on a rotatable member which member is rotatable about an axis of rotation extending parallel to the mandrels, the mandrels being equi-spaced about the axis of rotation; rotating the blanks on the mandrels; rotating a profiled grinding wheel; effecting rotary indexing of the rotatable member such that each of the blanks thereon successively moves relatively rapidly from a position spaced from the grinding wheel toward the grinding wheel to a position immediately adjacent the grinding wheel, moves relatively slowly from the adjacent position into contact with the grinding wheel and stops at the contact position for grinding to be completed, then moves rapidly away from the grinding wheel; and ejecting the ground work piece from the mandrel. Means are also provided for forming a through-passage axially in the work pieces.

Abstract: A powder-actuated tool includes a housing and a barrel assembly moveable therein and extending therefrom. A fastener driving member is moveable in the bore of a barrel assembly between a driving position and a driven position. A muffler member surrounds said barrel assembly external of said housing and forms a chamber between said muffler member and said barrel assembly. Suitable ports are provided in the barrel assembly to vent gases from the bore to the chamber.

Abstract: A collimated gun sight having a fluorescently illuminated reticle. The sight is contained in a single tube and is sized so as to be capable of being mounted on the muzzle of a gun.

Abstract: 1. A composition of matter comprised of an epoxy resin, a copolymer of butadiene and acrylic acid, a curing agent, and between about 2.5 and about 30 percent by weight of an inorganic metal salt selected from the group consisting of metal chromates, metal bichromates, metal phosphates, and mixtures thereof.

Abstract: A powder-actuated fastening gun including a housing in which a barrel assembly is mounted for movement between a locked position and an unlocked forward position. A percussion assembly is mounted in said housing for movement between a firing position and a fired position. A rod member, external of the barrel assembly, is moveable between a forward position and a rearward position. The rod member is releasably connected to the percussion assembly. A projection on the barrel assembly is adapted to engage the forward end of the rod member and move it from its forward to its rearward position as the barrel assembly is moved from its unlocked to its locked position. Actuating means are provided for disconnecting the percussion assembly and the rod member only when the rod member is in its rearward position. A second rod member may be provided which includes a safety catch to prevent disconnection of the percussion assembly and the rod member if the second rod member has not been moved rearwardly.

Abstract: A belt for holding a plurality of fasteners including a plurality of fastener receiving sleeves interconnected by webs. Each sleeve has a generally triangularly-shaped internal cross-sectional configuration. The corners of the internal triangle may be cut off to form flat surfaces. The fastener is engaged by the three sides of the triangle. The external surface of each adjacent sleeve has a planar portion positioned above and below the web which tapers away from said web. In addition, one end of each of the sleeves has a circular counter-bore therein and the other end has a groove therein extending parallel to the length of the belt. Each of the webs between adjacent sleeves has a V-shaped groove therein.

Abstract: An apparatus for use in connection with vehicle safety systems of the type including an inflatable confinement which is inflated by the combined energy of a stored fluid under pressure and gas generated by the burning of a propellant. Two distinct propellant charges are provided which are sequentially ignited. The outlet from the reservoir storing the fluid under pressure is opened in response to the ignition of the first propellant charge. The sequential ignition of the propellant charges reduces the peak pressure in the reservoir.

Abstract: A propellant charge comprising a matrix of granular propellant having interspersed therethrough compacted molded bodies of propellant. The density of the granular propellant is less than the density of the molded propellant bodies. The use of the mixed propellant charge enables a cartridge case of given dimensions to be loaded with a greater weight of propellant thereby enabling the achievement of greater projectile velocities in any given gun-ammunition system.

Abstract: A gas generator for an air bag or the like including an ignitor, a propellant, an outlet, and a cooling chamber positioned between the propellant and the outlet. The cooling chamber is filled with hollow balls with surface openings which are an effective heat sink and a trap for undesirable particulate matter so that the gas introduced into the air bag is sufficiently cool and clean to be vented into the passenger compartment of a motor vehicle.
