Patents by Inventor Thomas B. Lloyd

Thomas B. Lloyd 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).

  • Colored polymeric dielectric particles and method of manufacture
    Patent number: 5587242
    Abstract: A process for forming dielectric particles includes admixing a vinyl halide monomer and a crosslinker in a liquid dispersion medium to form a first mixture. A second mixture of an initiator and a stabilizer is prepared and added to the first mixture to form a third mixture in which the monomer polymerizes to form white crystalline polymer particles which are sonified for uniformity. The particles may be stained by exposure to a dehydrohalegenation reagent and dispersed in an electrophoretic fluid for use in an electrophoretic display.
    Type: Grant
    Filed: November 21, 1995
    Date of Patent: December 24, 1996
    Assignee: Copytele, Inc.
    Inventors: Wei-Hsin Hou, Thomas B. Lloyd, Frederic E. Schubert
