Patents by Inventor Edward M. Foley

Edward M. Foley 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).

  • Power metallurgy compacts and products of high performance alloys
    Patent number: 4129444
    Abstract: A powder metallurgy compact and a sintered product is provided from high performance alloys difficult to compact and/or sinter. The green compact comprises a mixture of the alloy powder, which, as a result of blending and extruding is coated with a film of a solid organic binder, and consolidated to discrete bodies of an intermediate density. The green compacts are sintered to produce a final solid product.
    Type: Grant
    Filed: August 22, 1977
    Date of Patent: December 12, 1978
    Assignee: Cabot Corporation
    Inventors: Dennis G. Dreyer, Edward M. Foley, Herbert E. Rogers, Jr.
  • Sintered high performance metal powder alloy
    Patent number: 4123266
    Abstract: Articles of high performance chromium-containing cobalt-base alloys sintered from powder contain boron in amounts between about 0.1 and 1.0%. The addition of boron widens the range of sintering temperatures sufficiently to make possible commercial production of articles of compositions which otherwise are difficult or impossible to sinter.

  • Diamond wire drawing die blanks and methods of making the same
    Patent number: 4078456
    Abstract: A wire drawing die blank and method of producing the same is provided in which the blank is made by:A. forming a compact of a superalloy powder containing a diamond and having an outside diameter smaller than the diameter of the drawing apparatus die aperture in which it is to be used,B. pressing a ring of powdered stainless steel having an inner annular opening adapted to receive the sintered superalloy compact containing a diamond and an outer diameter adapted to fit a drawing die apparatus aperture in which it is to be used, said powdered stainless steel having a shrinkage coefficient on sintering sufficient to cause the ring to shrink onto and tightly engage said compact, andC. sintering the stainless steel at a temperature below the melting point of the compact to consolidate and shrink the stainless steel onto the compact and to metallurgically bond the stainless steel and the superalloy of the compact.
