Abstract: A self-propelling projectile comprising a projectile body at the normally forward end of said projectile, a propellent charge at the normally rearward end of said projectile, and a primer element located between the ends of said projectile for ignition by side firing or percussion; there being means for maintaining said components in integrated relationship and with communication between said primer element and said propellent charge whereby upon explosion of said propellent charge the force of the latter will be directed against the base of the projectile body.

Abstract: The invention relates to a priming device for explosive projectiles and explosive chains, comprising a casing (10), provided with a through hole (11) in which a percussion pin (12) is slidably positioned, and a die member (22), removably mounted to the casing, in which an explosion chamber (21) of frusto-conical shape and with blind bottom is provided, longitudinal slots (25) and other ducts (27, 28) permitting the explosion gases, as generated by a caseless explosive pill (20), to be conveyed to a main explosive charge.

Abstract: The invention relates to a nail driving tool, acting by means of an explosive charge, which, besides the normal component parts, comprises an explosion chamber of particular shape and volume, whereby a blow applied to the rear end of the tool causes the explosive charge, compressed by the rear end of the nail driving piston in the explosion chamber, to reduce the volume of the latter according to a predetermined ratio, which reduction, in turn, originates the ignition of the explosive charge.
