  • Delay arming mechanism for fuzes
    Patent number: 4092927
    Abstract: A fuze is disclosed for use on projectiles fired generally at high speed. A unique delay arming mechanism is incorporated which utilizes pressure build-up within the fuze to control the period of delay in arming the fuze.

  • Thin walled steel cartridge case
    Patent number: 4041868
    Abstract: A thin walled steel cartridge case having a substantially larger internal volume than a conventional cartridge case. The cartridge case is fabricated from a high strength, heat treated carbon steel or boron steel and the wall contour in the head area is designed to avoid localized high stress. A low friction coating is applied to the outer surface of the cartridge case and serves to reduce stress concentrations in the head area and to reduce extraction force in the event of interference between the case and the chamber during extraction.
