Abstract: A system for detecting the approach of a vehicle toward the line of sight an antenna comprises an alerter for receiving an acoustic noise signal from the vehicle and determining whether the signal is increasing or decreasing. The increase of a noise signal indicates the approach of a vehicle and is used to activate a power supply to supply power to a digital signal processor. The digital signal processor receives the acoustic signal and performs a comparison to determine whether the signal in fact is noise produced by a vehicle. If so, the digital signal processor activates a radar based primary sensor which more accurately detects the approach of the vehicle and determines the instant at which the vehicle passes an antanna of the sensor. When the vehicle passes the antenna, the digital processor receives data and produces an output signal that can be used to activate a counter to count the passage of vehicles, surveillance equipment or to fuse a mine if the vehicle is assumed to be hostile.

Abstract: An improved parachute recovery system for a gun fired projectile is discld. The projectile has a nose, a payload and a base section. The base section has a hollow cylindrical parachute cannister which is separated from the base section by rearward motion of an internal piston which is actuated by expulsion gas pressure initiated by a time fuze. The parachute cannister is thereby exposed and jettisoned to cause inflation of a parachute attached to the base section so that the parachute floats down in a nose-deployed projectile position for a soft landing and recovery. Also disclosed are alternative embodiments of a projectile base-deployed parachute recovery system.

Abstract: The present invention is directed to an apparatus intended to allow detonon of munitions by the occurrence of a triggering event at a location remote from the actual munition. This apparatus contains a piezoelectric crystal which is deformed by the firing of a conventional blasting cap upon the happening of a triggering event. Deformation of the piezoelectric crystal generates an electric impulse sufficient to initiate an electric blasting cap thereby detonating the munition.

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: A quick disconnect coupling device formed from a female coupling portion a male portion for mating therewith. The outside diameter of the male portion is equal to the inside diameter of the female portion from the axial outer end of the male coupling to a point less than the total distance of penetration and a reduced outside diameter axially inward thereof. Each coupling portion has a valve to close the portions when they are disconnected. The coupling portions are configured to have a difference between the inside diameter of the female coupling portion and the reduced diameter of the male coupling. The female coupling portion is free to rotate about a point of maximum penetration by the male coupling portion to permit quick disconnection upon application of force to the outer end of either of the coupling portions. The edge of the male coupling portion may be tapered inwardly to assist in the rotation.
