Abstract: A percussion device for a medium or large caliber weapon incorporating a firing pin, spring means and a drive cam for the firing pin enabling its displacement in translation up to an “armed” position and the compression of the spring means, such device wherein it incorporates means to immobilize the firing in the “armed” position, these means being supported by the weapon breech and able to take up a position in which they immobilize the firing pin and another in which they release the firing pin.

Abstract: A contact safety device between two mechanical parts mobile which respect to one another to guarantee the internal kinematics, by the release or activation of control means, wherein said device incorporates a safety unit connected to one of said two mechanical parts enclosing a probe activated by one of said two mechanical part and amplifying means constituted by an amplifying lever activated by said probe and an immobilizing lock activated by said amplifying lever meshed on said control means so as to transform a rectilinear micro-movement into a circular movement of large magnitude.

Abstract: A casing includes a cylindrical envelope made of plastic material having a plug of plastic material at each end fitted with a metal reinforcement. The reinforcement is integral with the front plug and includes a ring that has a peripheral cylindrical part and an external edge that entirely covers a top end of the plug, which projects from the envelope.

Abstract: The invention relates to a system for loading a round such as a telescoped round into a pivoting chamber of a gun, in particular a medium caliber gun. The system comprises a feed device secured to the oscillating mass of the gun and laterally offset relative to the gun barrel. The feed device is situated between the trunnion axis of the gun and the pivoting chamber. The system further includes an insertion device for inserting a round into the chamber, which insertion device is secured to the recoil mass of the gun, is situated above the barrel, and lies substantially in the vertical plane in which the chamber pivots. The round is conveyed from the feed device to the insertion device by a feed star mounted to rotate about the barrel of the gun.

Abstract: The invention relates to a loading system for loading a round into a pivoting chamber of a gun. The system comprises a control device for controlling pivoting of the chamber, a feed device for feeding rounds and constituted by a feed station in alignment with the trunnion axis of the gun, a loading station in alignment with the axis of the chamber when it is in its loading position, and means for causing the round to pivot from the feed station to the loading station, and to load it into the chamber.
