Abstract: An ordnance firing mechanism for striking detonators by a strike pin which is translatable relative to a support, the strike pin being driven in translation by actuation apparatus including a lever connected to the strike pin and pivotable relative to the support, a pivotable pawl able to release the lever 4, a propelling device acting on the lever and affixed to the support 1, a driver acting on the pawl and through it implementing rotation of the lever thereby arming the strike pin and releasing the lever, the driver including a control rod for translation relative to the support and having recesses cooperating with the pawl and with a heel cooperating with the lever.

Abstract: A medium caliber automatic firearm with a high firing rate including a star drum which revolves in indexed fashion and which is in line with and driven by a cylinder star wheel, whose rotation is synchronized with that of the star drum, is mounted to the side of and is parallel to the star drum. A stripper is mounted between the star wheel and the star drum in order to separate cartridges from links at a point where the ammunition belt comes out of the star wheel while allowing the links to be evacuated from the firearm. A mechanism is also included which introduces the cartridges into successive chambers of the cylinder, the cartridges being lined up with the chambers by a star drum as the latter rotates.
