Abstract: A process for the production of compacted explosive charges, especially hollow charges, wherein a pulverulent explosive is compacted to form a charge within a compacting chamber and an inert body is arranged in the charge, the inert body is arranged within the compacting chamber in a predetermined starting position, to be displaceable in the compacting direction; and the pulverulent explosive surrounding the inert body is compacted under displacement of the inert body.

Abstract: Propellant charge device for recoilless weapons of the type having a barrel open at both ends with the propellant charge device being positioned behind a projectile and insertable into the front end of the barrel. The propellant charge device includes an elongated casing having a powder charge portion, a cavity portion and a tamp portion axially sequentially arranged within the casing and extending from the front to the rear thereof. The casing has a length such that it extends within the barrel of the weapon from the position thereof behind the projectile substantially over the entire length of the barrel.

Abstract: A retaining ring which may be utilized in hollow charge projectiles having a ring-shaped member and resilient tongues bent out of the plane of the ring member and having one end joined to the ring member. The resilient tongues extend approximately in the peripheral direction of the ring member and successive tongues are bent toward different sides of the ring member.
