Patents by Inventor Lee E. Wilson

Lee E. Wilson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Rotary pipe joint
    Patent number: 4323268
    Abstract: A pressure-tight, rotary pipe coupling joins rotating, high temperature fluid transmission lines. Pressure seals of the coupling are maintained at a temperature lower than that of the high temperature or primary transmitted fluid by thermally insulating the seals from the high temperature fluid and by pumping a fluid coolant through annular cavities located adjacent the seals. A balanced pressure structure substantially eliminates thrust forces between the coupling members and reduces rotating friction.
    Type: Grant
