Philip H. Klepesch 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).

  • Continuous blade axial-flow friction drag pump
    Patent number: 4655680
    Abstract: An axial flow pump includes multiple axially extending friction drag impellers formed of multiple nestled smooth continuous surface shells having a generally truncated spheroid configuration defining a plurality of axially extending elongated annular channels between the blades that induce fluid flow by means of frictional drag on the fluid.
    Type: Grant
    Filed: July 29, 1985
    Date of Patent: April 7, 1987
    Inventor: Philip H. Klepesch
  • Geothermal turbine
    Patent number: 4641498
    Abstract: A geothermal turbine for converting the energy of two-phase geothermal fluids to rotary power includes a housing having a generally cylindrical rotor chamber with a circular manifold, and a plurality of peripheral nozzles for communicating fluid to the rotor chamber, and a rotor mounted coaxially within the chamber incuding a plurality of converging overlapping blades mounted around a central hub and positioned within the rotor for engagement by fluid from the nozzles.
    Type: Grant
    Filed: September 30, 1982
    Date of Patent: February 10, 1987
    Assignee: Geothermal Energy Development Corporation
    Inventors: Peter Markovitch, Philip H. Klepesch
  • Continuous blade multi-stage pump
    Patent number: 4531887
    Abstract: A multi-stage axial flow pump includes multiple axial positioned impellers formed of multiple nestled smooth continuous surface blades having a generally truncated spheroid configuration defining a plurality of axially elongated annular channels between the blades that induce fluid flow by means of frictional drag on the fluid.
    Type: Grant
    Filed: June 6, 1983
    Date of Patent: July 30, 1985
    Inventor: Philip H. Klepesch
  • Total flow turbine
    Patent number: 4529354
    Abstract: A total flow turbine includes a housing defining a rotor chamber with a rotor rotatably mounted within the chamber and includes a plurality of passages opening at an outer radial face of the rotor and spiraling in a converging fashion inward to a central cavity which communicates with an outlet from the housing, with a plurality of nozzles spaced around the periphery of the housing angled toward the rotor for directing fluid toward the inlet of the passages.
