Abstract: Process for the manufacture of a propellant for base-bleed gas generators, thus for generators made of a gas-producing charge for the increase of range wherein a binder and one or more granular or powdery solid substances are used at least one of which is an oxidant, characterized thereby that the binder is a thermoplastically deformable elastomer, that solvents are added to said elastomer which is thoroughly mixed with the solid substance and that said elastomer is deposited thereon by removal of the solvent with the formation of a granulate.

Abstract: Exercise projectile substantially of a configuration defined by a pointed head prolonged by a tail-piece, characterized in that the projectile contains at least one explosive charge and an associated device for delayed firing, the duration of the delay substantially corresponding to the statistical flight time of the projectile from its starting time to the end of its intended useful trajectory.

Abstract: Process for the manufacture of insulated propellant sets for base-bleed gas generators, said propellant set consisting of a propellant containing one or more solid substances, at least one of which is an oxidant, and a binder being a thermoplastically deformable elastomer, characterized thereby that the propellant is introduced into an insulating envelope, which as an essential component contains a thermoplastically deformable elastomer suited for the binder, and is forced into the envelope at increased temperature.

Abstract: Electric circuit for firing a detonator for a projectile, comprising a generator for charging a first condenser and a second condenser connected in series, the aforesaid first condenser being connected in series with a contactor, a primer and a semi-conductor component with a controlled conductibility, and means for stabilizing the voltage of one of the aforesaid condensers and for preventing the firing of the primer during a predetermined time, in which the aforesaid means comprise a first voltage divider connected in parallel with the series connection of the aforesaid first condenser and second condenser and aforesaid contactor, the control electrode of the aforesaid semi-conductor component being connected with the intermediate point of the aforesaid first voltage divider comprising a transistor, the base of which is connected with the intermediate point of a second voltage divider connected in parallel with the aforesaid second condenser, the capacity of which is many times greater than the capacity of t

Abstract: Safety device for fuses, of the type which comprises a mobile element, which can be moved from a position of safety in which aforesaid mobile element may either be part of the pyrotechnical chain, of an electric or of an electronic circuit, or contain any one of such elements, or be solid or hollow in order to obstruct or permit the passage of an element of the fuse towards its active position, characterized by the combining of a tubular bolt, assuring the locking of aforesaid mobile element; of a sheath which at least partially surrounds aforesaid bolt, of balls entered in radial passages provided in aforesaid sheath; of a collar which can move axially by the effect of inertia so as to free aforesaid passages and permit the expulsion of aforesaid balls; and of an elastic means which stresses aforesaid collar towards the closing position of aforesaid passages.

Abstract: Improvements to grenades to be launched by a bullet, of the type comprising at least one capturing part which is distorted by the stress of the driving bullet when the grenade is launched, characterized by the fact that aforesaid capturing part is conditioned so as to be stressed radially when the bullet passes through, without axial displacement in the direction of the movement of the bullet.

Abstract: The invention pertains to a micro-detonator having a first cap and a second cap associated to a delaying charge. Said caps are respectively located in housings separated by a diaphragm having a striking protrusion to fire the second cap.
