  • Riveted cartridge venting
    Patent number: 8550004
    Abstract: An IM type steel cartridge whose base contains a central bore there through—within which bore is a steel base plug holding a primer cup, the base plug being held in place by a low melt, 220 to 250 degree F. melt eutectic solder—wherein, if the cartridge is subjected to an unforeseen thermal or kinetic event, the solder will melt, the base plug ejected, and the propellant will vent rather than explode. The solder bond between the base plug and the cartridge case within which it is held is capable of resisting the from about 72,000, to up to 90,000 psi, force generated within the firing chamber of the weapon by the ignition and firing of the cartridge.

  • Storage system for 25mm IM cartridges
    Patent number: 8028826
    Abstract: An improved 25 mm linked cartridge IM ammunition storage system, using existing ammunition cans, that simplifies the design of the storage system, and utilizes standoffs to separate the base of each cartridge from the ends of the ammunition can—thereby allowing the cartridges base IM venting system to vent properly, avoiding pressure build-up, and reducing the risk of explosion or detonation of the propellant.

  • Fin-stabilized ammunition
    Patent number: 6854394
    Abstract: Tracer visibility of APFSDS projectiles can be enhanced through a combination of increased steady state spin rate, reduced muzzle obscuration, and optimized airflow over the stabilizing fin geometry of the sub-projectile. The preferred means to increase steady state spin rates of the sub-projectile is to incline or deflect the fin blade tip portion, creating a larger, hotter burning, tracer plume.
