Susan T. Schmidt 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).

  • Light fixture with reflective polymeric composition and pigment package
    Patent number: 7176607
    Abstract: The present invention provides a light reflecting polymeric composition that includes at least one halogenated-flame-retardant-additive-free polymer having dispersed therein a pigment package including a combination of Sb2O3 and TiO2. The Sb2O3 and TiO2 preferably have an average particle size within the range of from about 0.05 ?m to about 1.0 ?m, and more preferably about 0.2 ?m. When used in combination, the Sb2O3 and TiO2 pigments synergistically interact together to provide a polymeric composition exhibiting a reflectivity that is substantially higher than can be obtained by the use of either of the pigments alone.
    Type: Grant
    Filed: November 24, 2004
    Date of Patent: February 13, 2007
    Assignee: Ferro Corporation
    Inventors: Deenadayalu Chundury, Richard Abrams, Ronald M. Harris, Mir Ali, Theophilus G. McGee, II, Susan T. Schmidt
