  • Fluorescent lamps and improved yytrium-containing phosphors useful therein
    Patent number: 5391959
    Abstract: Yttrium-containing phosphors can be stabilized for use in an aqueous slurry containing a binder, which slurry can be used for coating fluorescent lamps by treating with ammonium dihydrogen phosphate and ammonium hydrogen difluoride to inactivate free yttrium ions. The resulting aqueous slurry is stable and provides coated fluorescent lamps having uniform coatings that are bright and long lasting.
    Type: Grant
    Filed: April 30, 1993
    Date of Patent: February 21, 1995
    Assignee: General Electric Company
    Inventors: Mohamed E. Labib, Henry Wielicki, deceased, Pamela K. Whitman

  • Video disc lubricants
    Patent number: 4342659
    Abstract: Molecular distillation of methyl alkyl siloxanes of the formula ##STR1## wherein R.sub.1 and R.sub.2 are alkyl groups of 4-20 carbon atoms and m and p are integers to produce a distillate having a molecular weight fraction wherein the sum of m and p is about 4, produces an improved lubricant for the video disc, a lubricant that is stable to long term storage and to wide variations in temperature and relative humidity.
    Type: Grant
    Filed: August 9, 1979
    Date of Patent: August 3, 1982
    Assignee: RCA Corporation
    Inventors: Chih C. Wang, Lincoln Ekstrom, Thomas C. Lausman, Henry Wielicki

  • Video disc lubricants
    Patent number: 4216970
    Abstract: Siloxanes of the formula ##STR1## wherein R.sub.3 and R.sub.3 ' independently at each occurrence are long chain alkyl groups and m is an integer of 0 or 1, can be employed as lubricants for video discs. The lubricants are stable to long term storage and to wide variations in temperature and humidity.
    Type: Grant

  • Olefin-SO.sub.2 copolymer film adhesion to a substrate
    Patent number: 4007295
    Abstract: To improve the adherence of an olefin-SO.sub.2 copolymer film employed as an electron beam resist to a metallic substrate, a thin film of gold is first applied to the substrate. The resulting bond is strong enough to withstand exposure to electron beams, development of the resist film and electroplating of the film witout undercutting, lifting or distortion of the film.
    Type: Grant
