Abstract: A method for air delivery of ordnance and clearing of explosive mines and stacles from a navigable sea channel includes the step of providing quantities of ordnance adapted to survive impact with land and sea and prolonged immersion in sea water and to arm in response to air flow pressure and then detonate in response to receiving a preselected signal transmitted to the ordnance from a standoff location. The method also includes the step of delivering the quantities of ordnance through the air toward multiple sites in a navigable sea channel having obstacles and explosive mines therein so as to cause arming of the quantities of ordnance followed by impact thereof with the navigable sea channel and submersion and emplacement thereof at the multiple sites in the navigable sea channel.

Abstract: An apparatus for resizing the neck of a cartridge case which includes a housing secured to a stationary head of a reloading press. A support sleeve is attached within the housing such that the support sleeve can slide within a bore of the housing. The apparatus utilizes interchangeable bushings, located within the support sleeve, which each have substantially the same outside diameter but which have varying inside diameters. The bushings are marked with their inside diameter and the user selects a bushing with an inside diameter which the user determines will most accurately resize the neck. To change bushings, the top portion of the housing is separated from the bottom portion of the housing and the components inside the housing can then be slid out of the end of the bottom portion of the housing. A different bushing can be substituted for the one that was previously used.

Abstract: An apparatus for flight path correction of flying bodies, such as projectiles, rockets and the like, with the aid of a laser guide beam, wherein the course of the respective flying body is determined and processed in a measuring apparatus associated with the firing apparatus and containing an optical receiving detector in order to obtain an appropriate correction signal, and wherein the correction signal is then transmitted, through encoding of the laser guide beam, to a receiving apparatus disposed in the tail portion of the flying body. To determine the course of the flying body in a simple manner, both an optical light source for producing a light beam and an optical receiving detector are disposed on the measuring apparatus, and triple reflector or mirror elements, that reflect the incident light beam back in its initial direction independently of the respective angle of incidence, are disposed on the bottom of the flying body or at the ends of the guiding mechanism of the flying body.

Abstract: A muzzle-loading firearm having a breech loading receiver including a locking mechanism movable between an open position and a locked position; a barrel having a breech end engaging the receiver and a bore extending from the barrel's breech end; and a firing module receiving plug positioned within the barrel's breech, the plug including a chamber axially aligned with the barrel bore to receive an ejectable firing module having an igniter within a chamber.

Abstract: An electronic switch for triggering firing of munitions, the switch inclug an electrical circuit having a high voltage source, a sealed two electrode gap in communication with the high voltage source, a microgap in series with the sealed gap, an exploding foil initiator in communication with the microgap, and an energy storage capacitor bridging legs of the circuit between the high voltage source and the sealed gap. A trigger circuit is in communication with the high voltage source and a fire pulse generator, and is provided with a lead extending from the trigger circuit to one of said legs of said circuit between said sealed gap and said microgap. The energy storage capacitor is charged by the high voltage source to a voltage V which is substantially across the sealed gap. A pulse from the fire pulse generator activates the trigger circuit to provide a high voltage potential V.sub.t across the sealed gap, such that voltage V+V.sub.t breaks down the sealed gap to permit conduction therethrough.

Correlation circuitry comprising a logic network is provided to continuously compare the received signal with the modulation signal.

Abstract: A firearm, for example a semiautomatic weapon, in particular an automatic pistol, has control elements for controlling several operation or adjustment functions of the weapon. By means of an easily exchangeable functional element, for example a cam disk, it is possible to determine which operation or adjustment function, among all functions made possible by the weapon control elements, the user can set at his weapon. The functional element and/or a component for holding the functional element is designed and arranged in such a way that it can not only be easily fitted in and removed from the firearm not disassembled or only disassembled into its main parts, but also replaced by another type of functional element.

The sear includes a hooking element adapted to contact a bearing surface of the hammer to render the hammer immobile. Rotating movement of the sear is controlled by the hammer in such a way as to obtain clean contact between the hooking element and the bearing surface.

Abstract: A speed loader for loading a plurality of cartridges having shells into respective chambers of a revolver cylinder comprises a sheet form piece of resilient material formed with six substantially circular bores of diameter slightly less than the caliber of the shells. The cartridges can be fitted in the bores respectively and will be held in the bores by tension in the resilient material and frictional engagement between the resilient material and the shells of the cartridges. The six bores are arranged in two groups of three. The bores of the first group have their centers lying on a first arc of radius substantially equal to the radius of the circle on which the centers of the chambers lie, and the centers of the two outer bores are angularly spaced along the arc at approximately 60.degree. from the center of the inner bore.

Abstract: An electrically actuatable initiator (10) for an air bag inflator (20) includes an electrically sensitive ignition charge (280) disposed in an electrically conductive ignition cup (290). A plastic insulation cup (320) overlies the ignition cup (290). The insulation cup (320) electrically insulates the ignition cup (290) to block the flow of electric current into the ignition cup to prevent unintended actuation of the ignition charge (280). A locking ring member (380) is made from a shape-memory alloy which shrinks in diameter when heated above a predetermined temperature. The locking ring member (380) secures an output cup (360) to a retainer (150) and hermetically seals between the output cup and the retainer. A second locking ring member (310) secures the ignition cup (290) to a header (150) and seals between the ignition cup and the header.

Abstract: A firearm rest having a platform with mounting blocks at opposite ends and a shaft journaled in the mounting blocks and turned with an operator. A pair of links are hinged together in the middle forming a bed for resting the forward end of a gun stock. One of the ends of the joined links is hinged to one of the mounting blocks while the other end is hinged to a traveling nut that is threaded on the shaft and quickly disengagable therefrom. The height of the bed can be quickly raised or lowered by disengaging the nut from the shaft, manually moving the nut along the shaft thereby decreasing or increasing the distance between the ends of the joined links and changing the elevation of the bed. Fine adjustments can be made by rotating the operator when the nut is engaged with the shaft.

Abstract: The improved stabilizer has a hollow elongated preferably cylindrical housing with a central space extending the length thereof to open opposite ends. An end cap closes one end of the housing and bears a connector for attachment of the housing to a weapon. The opposite end of the housing has an end cap rotatably secured thereto to close the housing. The housing is filled with oil or grease. First and second springs, preferably coiled springs, are connected to the interior of the two end caps and to opposite ends of a weight suspended in the space of the housing. An indexer is provided on the rotatable end cap to indicate its rotated position and to releasably hold it in that position. As the end cap is rotated it increases or decreases, depending on its direction of rotation and the extent of its rotation, the tension on the springs, thus controlling their degree of resistance to displacement of the weight during shock absorption.
