  • Patent number: 7587978
    Abstract: An initiator is provided for a munitions device that is intended to strike a target substantially along a trajectory direction and contains an explosive within a case. The initiator includes a sleeve, first and second anvils and an initiation pellet disposed between the anvils. The sleeve is disposed within the case and adjacent to the explosive, and defines an initiator interior aligned substantially parallel to the trajectory direction. The sleeve includes one or more orifices that extend therethrough between the explosive and the interior, the orifices being disposed adjacent to the pellet. The pellet is composed of a reactive material that chemically responds as a non-explosive to kinetic and thermal stimuli.

  • Patent number: 7383775
    Abstract: A reactive munition uses a housing made from a housing in a state that is three-dimensionally rigid. The housing can be made of metal, such as aluminum. A reactive filler, such as powdered polytetrafluoroethylene (PTFE), fills the one or more cavities in the aluminum housing. A jacket encases the housing filled with the reactive filler.

  • Patent number: 4780276
    Abstract: About ten weight percent nickel is added to a Fe-base alloy which has a ferrite microstructure to improve the high temperature castability and crack resistance while about 0.2 weight percent zirconium is added for improved high temperature cyclic oxidation and corrosion resistance. The basic material is a high temperature FeCrAl heater alloy, and the addition provides a material suitable for burner rig nozzles.

  • Patent number: 4115271
    Abstract: A structure for dewatering solids utilizing a rotating cylindrical screen wherein the solids and water are directed to a portion of the rotating screen with the water passing into the interior of the screen and the solids adhering to the external surface of the screen. Doctor means remove substantially all of the solids from the external surface of the screen, after which the screen is washed by the water which has entered into the screen, the water being directed by a baffle into a flowing stream which strikes the screen and passes therethrough in a concentrated mass. The baffle is fixedly carried by a fixed shaft on which the screen is mounted for rotation.

  • Patent number: 3970855
    Abstract: Positron-emitting probes that have certain features that facilitate the use f positrons for nondestructive testing of fatigued metals. The features include the use of an unfatigued substrate for supporting the positron-emitting material, electric and/or magnetic fields to concentrate the positrons on the test item, and a thin scintillator window for use with those radioactive materials that emit a positron without emitting a time-correlated gamma photon.It should be understood that the foregoing abstract of the disclosure is for the purpose of providing a non-legal brief statement to serve as a searching-scanning tool for scientists, engineers and researchers and is not intended to limit the scope of the invention as disclosed herein nor is it intended that it should be used in interpreting or in any way limiting the scope of fair meaning of the appended claims.

  • Patent number: H2039
    Abstract: System for clearing both light and heavy obstacles, in which one or more flying metal plates are propelled against heavy obstacles by explosive forces which also expand a folded continous rod member into a curvilinear, generally annular configuration that cuts through light obstacles such as concertina wire in the process of unfolding.
