Abstract: A multifunctional case that is suitable for storing, carrying or launching marker beacon. The launching could be in a dense jungle to place the marker beacon atop tree branches to make it visible from the air, or the case may be adapted for a launching at sea. The case has a triggering mechanism for launching the marker beacon. It has alignment means that comprises a first alignment position for inhibiting a launch when storing or carrying the marker beacon within the case. The alignment means has a second position for placing the marker beacon in position to be launched. The launching takes place upon activation of a triggering mechanism that forms part of the case.

This component includes a stator having drive coils, an inertia wheel having a ring magnet, a shaft having a fixed upper bearing cartridge and a floating lower bearing cartridge mounted on the stator and supporting the inertia wheel, three snubber units spaced peripherally at equal angles around an axis of the shaft, and each snubber unit having a piston with a face engaging the shaft and having a bellows connected to the piston for withdrawing the piston from contact with the shaft upon exposure to vacuum pressure at launch completion.

Abstract: A planar top plate (32) has film cooling slots (34) therein. A rigid honeycomb structure (38) sealingly joins this top plate with bottom plate (36). Cooling air distributed by openings (50) impinges on the top plate and passes through metering openings (48) to the slots. A flat wall surface with reduced aerodynamic losses is maintained and the uniform support of the top plate avoids local distortion which would crack any heat resistant coating applied thereto.

Abstract: An individual mine launcher is designed to pneumatically launch high explve VOLCANO and MOPMS mines to simulate flight and impact typically encountered in field use. Electronic components and controls are used to monitor and initiate the arming sequence of the mine. Two configurations are used with the same pneumatic and electronic controls. The air-launch configuration allows the mine to be launched into the air at various specified testing elevation angles. The control impact configuration shoots the mine into a chamber where the mine hits an impact surface and then falls into a test monitoring area below.

Abstract: An auxiliary safety device intended for use as a magazine safety with a semi-automatic pistol of the Makarov design, said pistol being a blowback-operated, magazine-fed that is operable in double-action or single-action modes. The pistol's factory-original parts include a sear that pivots with respect to the pistol's frame about an axis that is defined by a transverse support post. The pistol has a sear cam that operates on the hammer in double-action operation, and operates on the sear in single-action operation. The auxiliary safety device includes two parts, the first being a relatively thin structural plate having front and rear portions. A relatively large and generally circular opening is located about midway between the front and rear portions; the opening is large enough to fit around and rotate with respect to the transverse post.

Abstract: The invention relates to a fuze for a submunition grenade which will selfstruct electrically in the event that the mechanical primary inertial functioning mode fails to operate upon striking an intended target.

Abstract: Upon a sudden deceleration of a vehicle, if an inertial body moves a predetermined amount against the urging force of a return spring, the trigger means will be released from engagement with the firing pin. Under the urging force of a spring, the firing pin is released from engagement with the trigger means, strikes and ignites a detonator so as to activate the actuator. The trigger means will not move until the inertial body has moved by the predetermined amount. Only after the inertial body has moved the predetermined amount, will the trigger means start to move suddenly and quickly. Therefore, friction at the time the inertial body engages the trigger means is kept constant. The stable operation of the sensor is thereby assured.

Abstract: A mine countermeasure device includes a passthrough mechanism and a mine neutralization package. The passthrough mechanism includes a first wheel with a raised rim and at least one radially oriented slot or notch, a clevis member rotatably engaging the axle of the first wheel, and a bail member slidably engaging the underside of the rim. A smaller wheel is pivotably connected at its axle to an angled member extending from the neutralization package. The neutralization package also includes a collapsed float, a gas generator to inflate the float, explosives to neutralize a mine, and an electric detonator for the explosives. The passthrough device is towed underwater by a sweep wire connected to the clevis member and to the bail member. When the sweep wire encounters a mine mooring, the sweep wire is pulled along the mooring until the mooring enters a slot of the first wheel.

Abstract: A controlled expanding small caliber bullet is disclosed which comprises a partition-type bullet, a rear cavity filled with a dense core and a high strength insert between the core and the body in the forward portion of the rear cavity.

Abstract: An explosive line including a pliable impervious outer casing and a filling of explosive material within the casing. An outer surface of the casing has a plurality of generally flat faces which are spaced about the explosive line so as to provide an outer surface of generally polygonal section.

Abstract: An object of the present invention is to provide a starting device which is prevented from operating erroneously, thus being high in reliability, and which, being simple in structure, is assembled with high efficiency, and is accordingly low in manufacturing cost. The starting device, according to the present invention, adapted to strike a detonator (10) in response to an acceleration higher than a predetermined value to activate a gas generator (8). In the staring device, an igniting pin (22) adapted to move towards the detonator (10) to collide with the detonator thereby to ignite the detonator is provided. An inertial body (23) is made of a permanent magnet for supplying kinetic energy to the igniting pin (22). An annular permanent magnet (24) the inside diameter of which is larger than the outside diameter of the inertial body (23) is provided.

Abstract: An apparatus for mortars for simulating the loading and firing of live ammunition by using a dummy shell. The apparatus includes a mortar, a spacer piece, and a dummy shell. The spacer piece and dummy shell are inserted into the mortar barrel.

Abstract: An ejection seat firing mechanism has a primary cartridge and a firing pin within a housing. A firing head is outside the housing coaxial with the primary cartridge and the firing pin, and a nut affixes the firing head to the firing pin thereby enclosing the housing. A first bore is formed through the flange of the housing and a second bore is formed in the nut spaced from the housing and aligned with the first bore in spaced parallel relation with the axis. A torquing shaft with an internally threaded axial coupling bore formed therein extends a determined distance into the torquing shaft. A spring is coaxially positioned around the torquing shaft and has a top end abutting the nut and a spaced opposite bottom end biasing the torquing shaft toward the flange. A bolt member extends through the first bore and is threadedly coupled with the torquing shaft via the coupling bore. The bolt provides a visual and sensory indication that the primary cartridge is installed and the firing head is torqued.

Abstract: A turbine shroud segment includes a center hook along one edge which retains the segment to the turbine structure while permitting thermal distortion of the segment. In a particular embodiment, a segment includes a pair of spaced center hooks, a first lateral hook, and a second lateral hook disposed oppositely of the first lateral hook. The spaced center hooks retain the segment and prevent radially inward movement of the center region of the segment. The lateral hooks provide supplemental retention while permitting the lateral edges of the segment to move radially outward in response to thermal distortion of the segment.
