Patents by Inventor Robert W. Smearing

Robert W. Smearing 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).

  • Modified polyetherimide resins
    Patent number: 4588779
    Abstract: The present invention relates to modified polyetherimide resins. Such resins contain high density polyethylene in an amount effective to raise the melt viscosity of the polyetherimide and reduce the tendency of the resin to stick to molds during injection molding.
    Type: Grant
    Filed: October 30, 1984
    Date of Patent: May 13, 1986
    Assignee: General Electric Company
    Inventor: Robert W. Smearing
  • Foamable polyetherimide resin formulation
    Patent number: 4543368
    Abstract: The present invention relates to a foamable polyetherimide resin. These foamable polyetherimides have an effective amount of a chemical blowing agent which decomposes at a temperature equal to or greater than the glass transition temperature of the polyetherimide resin and does not have an adverse effect on the polyetherimide.
    Type: Grant
    Filed: November 9, 1984
    Date of Patent: September 24, 1985
    Assignee: General Electric Company
    Inventors: Robert W. Smearing, Daniel E. Floryan
  • Storage stable reactive peroxide paste composition
    Patent number: 4360446
    Abstract: A stable and non-separating catalyst paste, reactive into a polyester system, said paste comprising a diacyl peroxide; a plasticizing amount of a vinyl-reactive di(hydroxyloweralkoxyalkyl) fumarate plasticizer; a finely divided mineral filler, e.g., calcium carbonate, in an amount sufficient to prevent the composition from physically separating into its components; the remainder, if any, being water.
    Type: Grant
    Filed: March 31, 1980
    Date of Patent: November 23, 1982
    Assignee: General Electric Company
    Inventor: Robert W. Smearing
  • Antifoaming resin compositions
    Patent number: 4297389
    Abstract: The foaming of resinous insulating materials under vacuum is substantially reduced by adding to the material a polydiene having primarily vinyl unsaturation.
    Type: Grant
    Filed: May 27, 1980
    Date of Patent: October 27, 1981
    Assignee: General Electric Company
    Inventor: Robert W. Smearing
  • Filled, two-part plastic-producing system
    Patent number: 4273689
    Abstract: A filled, two-part plastic-producing system is described. This system is based on the use of unsaturated polyester resin and a benzoyl peroxide paste curing agent. By modification of either or both parts of the system, its utility is greatly enhanced. Further a cement composition useful in a filled two-part grout-producing system is described.

    Inventor: Robert W. Smearing
  • Storage stable polyester monomer compositions with inhibitor, promoter, and stabilizer
    Patent number: 4259228
    Abstract: Storage stable, fluent, ambient temperature polymerizable resin compositions comprise:(a) an unsaturated polymerizable polyester resin;(b) a monomeric polymerizable ethylenic compound;(c) a gelation inhibitor;(d) a gelation promoter comprising a tertiary amine; and(e) an effective, stabilizing amount of a copper compound which is soluble in said composition in combination with a quaternary ammonium salt.Such compositions containing inert fillers are also disclosed.

  • Storage stable peroxide paste composition
    Patent number: 4255277
    Abstract: A stable and non-separating catalyst paste comprising a diacyl peroxide; a minor proportion of water; a finely divided calcium carbonate in an amount sufficient to prevent the composition from physically separating into its components; the remainder, if any, being a chemically inert plasticizer.
