  • Patent number: 5062365
    Abstract: A rapid burning propellant charge for applications including igniters, launch eject motors, and gas generators for automobile air bags. The propellant charge comprises a reticulated substrate having a quantity of interconnected ligaments and a coating of solid propellant material on the ligaments. In order to provide a large amount of surface area for a fast burn time, interstices are between coated ligaments to define propellant surface area for combustion. In applications where minimum smoke is desired, the reticulated substrate is preferably composed of carbon, graphite, or a non-combustible material, and the solid propellant material is preferably a minimum smoke type.

  • Patent number: 5039368
    Abstract: Thermoplastic matrix composite cylinders, pipes, and other hollow bodies are formed by a winding technique using thermoplastic filaments. The filaments are fed from a vertically moving winding head onto the surface of a rotating mandrel. The filaments are preheated to soften them and then pass beneath a heated compaction roller bearing against the mandrel. The compaction roller is castered so as to follow a helical path. Several plies of the thermoplastic material may be laid down in this fashion, the surface of each prior ply being heated so that the layers fuse properly. When cooled to below its solidification temperature, the formed object is removed from the mandrel.

  • Patent number: 4729382
    Abstract: An apparatus and method is disclosed for automatically determining the pulse rate and systolic and diastolic blood pressure. The apparatus comprises a device for detecting arterial pulsations in a subject's body. The improvement comprising a sensor in a pressurized bladder and responsive to arterially induced pressure pulsations. The sensor comprises a pressure transducer chamber and a pressure transducer. The pressure transducer chamber contains a pressure equalization passageway communicating with the interior of the bladder and the interior of the pressure transducer chamber. The pressure equalization passageway equalizes the pressure between the bladder and the chamber to prevent the pressure in the bladder from impending upon the pressure transducer. A method is disclosed for automatically determining pulse rate and systolic and diastolic blood pressure.
