Abstract: An explosive powder charge operated setting tool includes a housing containing an axially extending fastening element guide which is axially displaceable opposite to the driving direction when the front end of the setting tool is pressed against a structural component into which a fastening element is to be driven. When it is axially displaced, the fastening element guide displaces a piston guide which, in turn, means a device into a cocked position so that a firing pin in the device is ready to ignite the powder charge. The fastening element guide has an axially extending feed slot aligned with a magazine forming a part of the housing. Fastening elements are connected together in a belt-like fashion by guide bushes each positioned on a fastening element. The feed slot has a stepped width extending in the axial direction so that in axial displacement of the fastening elements only a single fastening element can be positioned to be driven from the fastening element guide.

Abstract: Upon the occurrence of a preset event, compressed gas is released from a mber and travels to fill a bellows. The bellows inflates and provides the power to eject a force transfer strut from the cavity of one body. The strut being fixedly attached at one end to a second body, this ejection accomplishes the separation of the two bodies from each other.

Abstract: A device, for releasing a locked trigger set by a set-trigger mechanism in a gun having a receiver, a bolt loosely inserted in the receiver, and a bolt handle for rotating and reciprocating the bolt so as to load a bullet and set in a fire-enabling state, includes an abutting portion formed on the bolt handle, and a release link positioned for contact with the abutting portion and a trigger in accordance with a rotational movement of the bolt handle. The trigger locked by the set-trigger mechanism is released when the bolt handle is rotated up to a fire-disabling position, causing the abutting portion to push the release link against the trigger to unlock it. With this construction above, when the bolt handle is in the fire-disabling state, the trigger can never be in the locked position, which enables a safe and secure release of the locked trigger and safe bullet loading and/or removal.

Abstract: A self-actuating slide valve system for launching a device in a fluid envnment is provided. An interior channel, in which the device is positioned, is provided with first and second openings in its radial walls for allowing the passage of pressurized fluid into the interior channel. The first opening is located at least partially behind a tail end of the device and the second opening is located forward of the first opening. A sleeve is slidably fitted within a portion of the interior channel and around at least a portion of the device. The sleeve is movable between at least a first and second position. In the first position, the sleeve prevents the pressurized fluid from entering the interior channel through the first opening. In the second position, the sleeve allows the pressurized fluid to enter the interior channel through the first opening whereby the pressurized fluid can act on the tail end of the device to launch same through an axial opening of the interior channel.

A source of fluid under pressure and conduits therefrom to said actuator valves for operating said fluid operated mechanisms. A control panel has a series of manipulatable fluid control members associated with the actuator valves for operating the fluid operated mechanisms, and these members are movable from a first position to a second position to effect the direction of flow of fluid to and from the actuator valves and thereby to move the mechanisms between the first and second positions. Visual indicators indicate the position of the associated fluid control members and thereby that of the fluid operated mechanisms.

Abstract: An electric primer for cartridge ammunition (e.g., Phalanx 20 mm cartridg is designed to minimize antenna coupling, capacitive coupling, and aperture coupling of stray electromagnetic radiation thereinto for avoiding accidental primer detonation with resulting ignition of cartridge propellant. The primer is provide with a button electrode which is deeply recessed totally behind a small diameter access aperture which physically guards the button electrode from antenna and capacitive coupling. Furthermore, the small opening channels stray radiation about its periphery rather than admitting it to the button.

Abstract: A propellant strip assembly for use in propellant actuated fastener driving tools. The assembly includes a carrying strip which contains a plurality of pockets which each hold a propellant charge and a sensitizer to activate the charge. The carrying strip is adhesively joined to a cover strip to isolate the individual charges, and each pocket is also sealed around its periphery to further improve the isolation. The cover strip may contain a ribbed section to physically separate the charge and sensitizer within each pocket to aid in prevention of accidental ignition.

Abstract: An exhaust gas management system for missile launch arrangements which incorporates multiple launch cells exhausting into a common plenum. The system provides a flow passage configuration with a transition section that permits rocket exhaust flow gas to expand to fill the channel area downstream of the nozzle exit. Automatic aft closure members are included which serve to close off the flow passages to inactive cells while providing an open passage for exhaust gases from an active cell undergoing a missile firing. This arrangement prevents back flow or recirculation of exhaust gases into the volume in the cell which is upstream of the rocket nozzle exit.

Abstract: A method of casting high melting point metal such as refractory metals into ngots to provide substantially improved strength and density. A quantity of high melting point metal is placed in an arc area of a furnace having a "T" shaped vacuum chamber with a pair of opposing electrodes which generate an arc to cause droplets of the metal to melt from the heat thereby generated. The droplets fall into a mold positioned to receive the droplets and shaped to form the desired ingot. The method includes an additional step of further heating the droplets as they fall into the mold with a plasma arc gun mounted inside the furnace. The gun is directed to impinge its heat torch to control the rate of solidification such that a small pool of the liquid phase is maintained on the ingot. The last step comprises solidifying the molten metal in the ingot by controlling the plasma arc gun and the heat generated from it.

Abstract: An apparatus is provided for controllably positioning a movable element within a hydraulic motor in response to a flow request signal. An electric circuit receives the flow request signal and responsively produces an energization signal. An electromagnetic actuator has a core, and a coil with a plurality of windings wound as a helix around the core. The coil is adapted to receive the energization signal and responsively produce a magnetic force proportional to the magnitude of the energization signal forcing the core to move bidirectionally relative to the coil. A mechanical coupling has one end connected to and movable with the core. A directional valve includes a spool connected to the other end of the mechanical coupling. The directional valve precisely meters pressurized fluid to the motor causing the movable element to move in response to the movement of the core.
