An explosive device which has a retainer with a groove, that houses a charge adapted to produce a shock wave upon detonation. The retainer is attached to a target such as an airplane canopy, so that the charge is spaced from the target a predetermined distance. Between the charge and the target is a transmitting medium that transmits the shock waves of the charge to the target. The transmitting medium is constructed from an essentially incompressible material such as rubber, which transmits the shock waves without dissipating much of the blast energy of the charge.

Hydraulic severance shaped explosive

A self-contained device for selectively discharging a pressurized gas within a hermetically sealed vessel to which it has been sealed, to enable a leak testing of the vessel. A linear actuator is functioned to open a small, high pressure cylinder that has been charged with a detector gas. The mechanism is preferably mounted to the interior of a lid which is then sealed onto the vessel which is to be tested. Proper functioning of the device may be confirmed electrically, since circuit continuity between an electrical contact pin and at least one additional portion on the exterior surface of the vessel will be permanently broken after proper functioning.

Mechanism for leak testing of hermetically sealed vessels

This invention teaches a method and the resultant product of preparing consolidated propellant charges that incorporate an integral ignition compound, specifically certain simple salts of decahydrodecaboric acid and coprecipitates of these salts with an oxidizer. The charges so prepared exhibit substantially improved ignition and breakup compared to untreated charges, especially at low temperature, because each of the individual consolidated grains are surrounded by the salts taught herein.

Consolidated charges incorporating integral ignition compounds

This invention teaches preparation of individual and uncoated propellant grains by incorporating a coating or integral layer of ignition compound, specifically simple salts of decahydrodecaboric acid and coprecipitates of these salts with an oxidizer. The resulting propellant grains so prepared exhibit substantially improved ignition capability, virtually independent of ambient conditioning temperature conditions at the time of use.
