Abstract: A pyrotechnical dowel has a shank and a deformation chamber located at the forward end of the shank. The chamber contains a blasting cap. Triggering of the blasting cap takes place from the rearward end of the shank by means of a triggering tool which is introduced into a longitudinal duct within the shank and which comes into direct contact with a bottom of the blasting cap.

Abstract: Polyethylene crosslinked by high-energy radiation, preferably electron beams, is an effective material for the manufacture of ammunition elements, preferably cases for cartridges. The case is produced by irradiating a molded case component of polyethylene with high-energy radiation.

Abstract: A spin-stabilized training missile is equipped with a stabilizer device for reducing spinning in order to decrease the flight range. The training missile is designed so that its stabilization attainable solely by the spin upon firing is not sufficient for a stable flight in the practice range. The required additional stabilizing in the practice range is obtained by a stabilizer device or control airfoil effecting simultaneously, after leaving the practice range, such a spin reduction that the training missile becomes unstable and the range of flight is controlled.

Abstract: A firedamp-safe propellant charge comprising a pyrotechnical gas-yielding propellant, said propellant coated with a polymer and/or amides of C.sub.2 -C.sub.4 dicarboxylic acids and/or ammonium oxalate, which composition, upon ignition of the propellant, disintegrates into radicals, said coating being present on said popellant in an amount of 15 to 30 weight percent based upon the weight of said propellant charge.

Abstract: A fastening element having a cavity containing an explosive charge arranged so that, upon explosion of the explosive charge, anchoring of the fastening element in a bore of a workpiece takes place automatically. This fastening element functions both as a rivet and nail in combination and comprises sleeve means defining the cavity containing the explosive charge at one end and providing an aperture at the other end, and a nail disposed within the sleeve means, said nail comprising a head, shank and a tip and being arranged to be driven outside the aperture formed in the other end of the sleeve means. The head of the nail acts as a piston which can be driven by explosion of the explosive charge and as a stop which arrests the driving-out movement when the shank of the nail has passed through said aperture.

Abstract: A pyrotechnical sealing material comprises a heat-foamable synthetic resin capable of being foamed with the aid of a burnable pyrotechnical composition. The sealing material is in the form of a cord having a core made of the pyrotechnical composition and a casing separated from the core by a flexible sheath. The casing is formed from the heat-foamable synthetic resin.

Abstract: A sabot projectile including a sabot, a subcaliber projectile and a hood arranged in front of the sabot and surrounding at least a part of the projectile. The hood is coupled to the sabot and/or the projectile and is separable therefrom. The sabot is provided with at least one bore extending in the longitudinal direction and arranged for exposure to propellant gases upon firing of the sabot projectile from the barrel of a weapon and for directing the propellant gases onto the hood for accelerating the hood relative to the projectile while the sabot projectile is within the barrel of the weapon.

Abstract: A training projectile having an auxiliary drive mechanism for counteracting the aerodynamic resistance to which the projectile is exposed during the training flight phase of projectile travel. The auxiliary drive mechanism preferably is in the form of a rocket or jet drive. The training projectile is also provided with a mass so that the ratio of the resultant axial force to the mass of the training projectile is at least approximately equal to the ratio of the resistance force to the mass of a corresponding live projectile during the training flight phase.

Abstract: A short-range projectile for practice ammunition having an axial air inlet duct emanating from the front end of the projectile and at least one outlet duct connecting the inlet duct with the jacket of the projectile. At least one of the inlet and outlet ducts are blocked during the initial flight path of the projectile by a blocking member displaceable in a chronologically controlled manner. The blocking member is displaceable in response to an air pressure head occurring during flight of the projectile from a starting position for preventing the influx of air from the inlet duct to the outlet duct to a final position wherein communication and influx of air from the inlet duct to the outlet duct is completely enabled.
