Abstract:
A PROCESS FOR PRODUCING SHAPED POWDER ARTICLES FOR PROPELLENT CHARGES BY PRESSING POROUS POWDER GRAINS HAVING EXTERNAL GEOMETRIC SHAPES EXHIBITING EDGES, SPIKES OR THE LIKE WHICH PERMIT THE GRAINS TO INTERLOCK WITH EACH OTHER. PREFERABLY THE GRAINS HAVE T, X, Y, OR V-SHAPES, ALSO DSCLOSED ARE SHAPED POWDER ARTICLES PRODUCED BY THIS PROCESS.
Abstract:
A propellant charge in the form of a powder strip having holes or apertures therein for indicating the length thereof to be used in a firing device having a cartridge chamber with guides on one wall to effect a coiling of the powder strip when inserted thereinto by way of an inlet slit from a magazine via a measuring device.
Abstract:
This invention relates to an irritant agent element such as a tear gas element which can be used for temporarily disabling persons at the target site with a minimum of risk of physical injuries and mechanical damage. The element comprises a tear gas cartridge containing tear gas-producing bodies and detonator and combustion means for deflagrating said tear gas-producing bodies, the feature of the invention residing in the provision of an envelope of resilient, readily deformable material surrounding said cartridge. Channels are provided in the envelope for the emanation of the tear gas from the cartridge.
Abstract:
A safety belt for motor vehicles is connected to a tensioning device which is responsive to a deceleration detector for tensioning the belt upon detection of a predetermined degree of deceleration indicating collision with an object. In this way the safety belt can be worn loosely with comfort under normal conditions and the tensioning device will automatiallly provide for tightening the belt to the proper degree to safely restrain the passenger in the event of a collision.
Abstract:
Device for inflating safety cushions in a vehicle having an electrically ignitable cartridge provided with a pyrotechnical mixture free of brisant or high explosive within a cartridge casing of low strength material. The cartridge casing material is of a low strength so as to prevent the cartridge casing acting as a tamp for accommodating inadvertent detonation of the cartridge by itself. The cartridge is arranged within a pressure tank equipped with a liquid gas in communication with the interior of a safety cushion by means of an extension having at least one gas passage aperture, which extension is sealed with respect to the liquid gas by a bursting or rupturing diaphragm. The pressure tank includes a cartridge housing for removably accommodating the cartridge. The walls of the cartridge housing are of a high strength material and are so dimensioned with respect to the cartridge casing that the cartridge housing serves as a tamp for facilitating optimum detonation of the high explosive free pyrotechnical mixture.
Abstract:
The present disclosure is directed to a propellant charge for industrial use which comprises a body of a propellant powder having a centrally disposed recess extending therethrough, said recess containing a percussion sensitive primer substance, said primer substance being housed in the recess in such a manner that the compacting of the primer substance remains below the value required for the ignition thereof upon a sudden unexpected compression of the propellant charge in the direction of the axis of the recess.
