Us Patents

  • Separator For Starved Electrolyte Lead/Acid Battery

    view source
  • US Patent:
    42333792, Nov 11, 1980
  • Filed:
    May 17, 1979
  • Appl. No.:
    6/039708
  • Inventors:
    Stephen E. Gross - Littleton CO
    Clifford W. Cain - Littleton CO
    Paul D. Bilawsky - Lakewood CO
    Norman B. Scheffel - Parker CO
  • Assignee:
    Johns-Manville Corporation - Denver CO
  • International Classification:
    H01M 216
  • US Classification:
    429247
  • Abstract:
    Compositions and papers made therefrom useful as separator materials in starved electrolyte lead/acid batteries are described. The compositions comprise a mixture of 30% to 80% by weight of perlite and 20% to 70% by weight of glass fibers. The glass fibers have diameters in the range of from 0. 3 to 1. 0 micrometers while the perlite has particle sizes in the range of from about 3 to about 100 micrometers.
  • Milled Talc Material And Milling Method

  • US Patent:
    39321940, Jan 13, 1976
  • Filed:
    Feb 11, 1974
  • Appl. No.:
    5/441192
  • Inventors:
    Richard Seyb Lamar - Littleton CO
    Norman Bach Scheffel - Parker CO
  • Assignee:
    Johns-Manville Corporation - Denver CO
  • International Classification:
    C09C 102
  • US Classification:
    106306
  • Abstract:
    Milled talc materials containing about twenty to about thirty-five weight percent tremolite having particle size distributions such that no more than five percent of the particles are larger than 10 microns, no more than 12 percent of the particles are larger than five microns and no more than 15 percent of the particles are smaller than 0. 3 microns in equivalent spherical diameter have improved opacifying properties for use in paper, rubber, plastics and paint manufacture. The materials can be obtained by jet or fluid energy milling and by controlling the milling variables to produce particle size distributions within the critical range.
