  • Patent number: 6860951
    Abstract: A low-solids gas generating composition, which is a mixture of a fuel selected for the group consisting of cellulose, cellulose acetate, hexamine, and mixtures thereof, and an oxidizer selected from the group consisting of ceric ammonium nitrate, lithium nitrate, lithium perchlorate, sodium perchlorate, phase stabilized ammonium nitrate, a combination of ammonium nitrate with potassium nitrate, potassium perchlorate, or mixtures thereof, such that the combination is a solid solution, a mixture of ammonium perchlorate and at least one alkali metal salt, and mixtures thereof. The combination of ammonium nitrate with other salts in solid solution is intended to phase stabilize the ammonium nitrate. The oxidizer-fuel mixture is within about 4 percent of stoichiometric balance. Useful alkali metal salts include lithium carbonate, lithium nitrate, sodium nitrate, potassium nitrate, and mixtures thereof.
    Type: Grant

    Date of Patent: March 1, 2005
    Assignee: Talley Defense Systems, Inc.
    Inventors: Gregory D. Knowlton, Christopher P. Ludwig, Daniel V. Haun
  • Patent number: 6622629
    Abstract: A fuze for a submunition is miniaturized in size by forming the fuze of a micro-electromechanical systems (“MEMS”) velocity sensor (38, 32, 34 and 36), a MEMs shock detector (31), a DC power supply (30) and one of the MEMs arm-fire device (2, FIG. 1) or MEMs safe and arm device (2, FIG. 5). Multiple fuzes may be incorporated in a fuze to ensure detonation of the explosive charge, should one fuze fail. A millimeter-microwave (“MMW”) receiver-decoder may be included to permit remote detonation on command from a remote transmitter (52) and/or a microprocessor (54) may be included to time the detonation to the physical characteristics of the target.
