  • Patent number: 6049997
    Abstract: Specifically configured dual rotor, multi-lobed, rotary gas compressors in a piping system will provide clean gas heating and re-circulation that will quickly and efficiently heat a connected process chamber or process piping section. Substantial heat is quickly generated through mechanical agitation of the gas molecules that pass through the inlet and outlet of a dual rotor, multi-lobed, rotary gas compressor. The invention application of a dual rotor, multi-lobed, rotary gas compressor as a means of imparting heat to a gas stream provides an economical source of convective heat for closed and open loop piping applications.
    Type: Grant

  • Patent number: 5548895
    Abstract: A method of connecting an end of a plastic, male vacuum-component to a female component in a vacuum system, by attaching an elastomeric sealing member to the end of the male vacuum-component, and inserting the end of the male vacuum-component into a female vacuum-component until the elastomeric sealing member is in at least partial contact with a mating surface-portion of the female vacuum-component, repeating the steps a plurality of times for other mating male and female vacuum-components, and then creating a vacuum in the vacuum-system in which the male vacuum-component has become part, in order to erect a stand-alone structure which is held firmly together by binding forces formed by the vacuum.

  • Patent number: 5516154
    Abstract: The Invention relates specifically to an improved method of joining plastic socket fit piping components for vacuum, pressure, and structural applications where a leak and contamination free connection is needed. A unique Dual Face/Circumferential Elastomer Seal is installed in a special Seal Groove located on the end of the male component. The male components are then inserted into the female sockets until contact is made between the Dual Face/Circumferential Elastomer Seals and the Female Socket Base Surfaces. The final assembly is evacuated with a vacuum pump to actuate and fully compress the seals. The final assembly is then checked for leaks. If the connections are to remain under vacuum and the ability to disassemble is advantageous, no further work is required.
