  • Patent number: 6246123
    Abstract: A mold compound made from a polymer resin and an isorefringent, transparent filler is used to form optical electronic components (10, 20, 30). The mold compound can be used to form a lens (13) on a display device (10), to form the outer housing (21) of a waveguide (20), or to form a dome (34) that reflects light from a light emitting device (32) to a light detecting device (33).
    Type: Grant
    Filed: May 4, 1998
    Date of Patent: June 12, 2001
    Assignee: Motorola, Inc.
    Inventors: James F. Landers, Jr., Robert K. Denton, Jr.
  • Patent number: 4992259
    Abstract: A stable and clear aqueous solution of zinc salt useful as a mouthrinse and a gel dentifrice. In a preferred embodiment the aqueous solution comprises zinc chloride codissolved with a complexing agent of sodium gluconate, in a naturally derived anionic polymer of sodium carboxymethylcellulose. This solution is advantageous because it maintains clarity and chemical stability in temperatures of from about to about C. and may be alcohol-free. The anionic polymer acts as a buffer to provide a solution with a pH in a desirable range of from about 5.7 to about 6.5, which limits astringency and tartness.

  • Patent number: 4781940
    Abstract: A filler for use in dental composites is made by the following process:(a) finely divided silica, such as fumed silica, is coated with a polymerizable monomeric material by (e.g., an acrylic monomer) by mixing the silica with an organic solvent solution of the monomer;(b) the solvent is removed by evaporation by any convenient means;(c) the coated silica particles are individualized, as by screening, to produce a powder of a predetermined particle size (e.g., 90 microns or smaller); and(d) the resin is then polymerized.Some individualization of the product of step (d) may be required. Light screening is usually sufficient.
