  • Alternator and method of manufacture
    Patent number: 6849974
    Abstract: An alternator has a molded plastic, electrically conductive D.E. frame in which a sealed bearing is molded in place with the formation of the D.E. frame 14. When the D.E. frame is removed from its plastics injection mold and while the frame is still hot, the stator is installed in the D.E. frame and the frame allowed to cool and constrict about the stator. The companion S.R.E. frame is preferably fabricated of non-conductive plastics material.
    Type: Grant
    Filed: March 5, 2004
    Date of Patent: February 1, 2005
    Assignee: Altech Generating Systems, LLC
    Inventors: Steven E. Howe, Donald C. Lipscomb, Jr.

  • Recovery of oil from a shale containing the same
    Patent number: 5013428
    Abstract: Enhanced recovery of oil from an oil-containing particulate shale sludge is achieved by contacting the sludge with a light hydrocarbon solvent fraction, obtained from the processing of oil derived from the shale, in the presence of water to form an oil-solvent liquid phase which is separated from an aqueous phase containing oil-depleted shale. The oil-solvent liquid phase when introduced into a slurry of product oil and particulate contained within a shale retort provides several advantages, including lowering the viscosity of the product oil and enhanced separation of the product oil from the particulate shale.
