Us Patents

  • Dome And Window For Missiles And Launch Tubes With High Ultraviolet Transmittance

    view source
  • US Patent:
    49307312, Jun 5, 1990
  • Filed:
    Jun 2, 1989
  • Appl. No.:
    7/363355
  • Inventors:
    Donald W. Roy - Golden CO
    James L. Hastert - Lakewood CO
  • Assignee:
    Coors Porcelain Company - Golden CO
  • International Classification:
    F41G 726
    F42C 1904
    B29D 1100
    C04B 3562
  • US Classification:
    244316
  • Abstract:
    A dome and window for missiles and launch tubes is provided having high ultraviolet transmittance and high strength properties. The domes and windows have, in their uncoated state, and with a thickness of about 1. 88 mm, a transmittance greater than about 80%, preferably greater than about 82%, and more preferably greater than about 85%, at a wavelength of 0. 4 microns to 0. 5 microns. The domes and windows preferably have a transmittance per 1. 88 mm thickness at all wavelengths in the wavelength range between 3. 0 microns and 4. 0 microns of at least about 81%. The domes and windows have a flexural strength of at least about 20,000 psi and a knoop hardness of at least about 1350 kg mm. sup. -2. The domes and windows are formed of a transparent, sintered polycrystalline magnesia-alumina spinel. The polycrystalline sintered spinel is formed in a two-step process comprising forming a closed porosity body such as by hot-pressing or pressureless sintering followed by a hot isostatic pressure treatment step to reduce residual porosity to less than about 0.
  • Method For Manufacturing A Transparent Ceramic Body

    view source
  • US Patent:
    39742490, Aug 10, 1976
  • Filed:
    Oct 10, 1972
  • Appl. No.:
    5/296420
  • Inventors:
    Donald W. Roy - Golden CO
    Franklin J. Stermole - Golden CO
  • Assignee:
    Coors Porcelain Company - Golden CO
  • International Classification:
    F27B 904
    F27B 910
  • US Classification:
    264 65
  • Abstract:
    The present invention provides a high heat resistant, light transmitting, thermal shock resistant and high strength sintered ceramic body containing at least about 98% by weight magnesia-alumina spinel and a method of manufacturing the same which comprises forming a uniform mixture containing approximately equal molar amounts of magnesia and alumina plus lithium fluoride in an amount of about 2% by weight of the mixture, the alumina in the mixture having an average particle size of less than 0. 5 microns; calcining the mixture at such a temperature and under such conditions as will result in substantially less than total reaction to form spinel during calcining, i. e. less than 80% and preferably less than 50%; pressing the mixture into a self-sustaining compact having a density of at least about 2 grams per cubic centimeter; and then firing the compact, preferably in a wet hydrogen atmosphere, to a temperature of from about 1600. degree. to 1900. degree. C.
  • Metallized Spinel With High Transmittance And Process For Producing

  • US Patent:
    50827391, Jan 21, 1992
  • Filed:
    Apr 22, 1988
  • Appl. No.:
    7/184729
  • Inventors:
    Donald W. Roy - Golden CO
    James L. Hastert - Lakewood CO
    Kenneth E. Green - Arvada CO
    Aurielo Trujillo - Arvada CO
  • Assignee:
    Coors Porcelain Company - Golden CO
  • International Classification:
    C04B 3502
    B29D 1100
  • US Classification:
    428450
  • Abstract:
    A metallized spinel material and a method for producing a metallized spinel material are provided. The spinel is a high-transmissive material and, particularly, has high transmission in the ultraviolet and, preferably, the visible infrared wavelength regions as well. The high-transmissivity spinel material is metallized by applying the slurry containing a metal, such as tungsten, molybdenum and/or manganese to the substrate, and firing at en elevated temperature such as 1200. degree. to 1800. degree. C. , preferably 1500. degree. to 1800. degree. C. for about 1/2 hour in a non-oxidizing atmosphere.
  • Application Of Transparent Polycrystalline Body With High Ultraviolet Transmittance

    view source
  • US Patent:
    49835556, Jan 8, 1991
  • Filed:
    Apr 22, 1988
  • Appl. No.:
    7/185189
  • Inventors:
    Donald W. Roy - Golden CO
    James L. Hastert - Lakewood CO
  • Assignee:
    Coors Porcelain Company - Golden CO
  • International Classification:
    C04B 3502
  • US Classification:
    501120
  • Abstract:
    A transparent polycrystalline body having high ultraviolet transmissivity is provided. The body is preferably a sintered magnesia-alumina spinel body having a transmittance of at least 85 percent in the wavelength range from 0. 4 microns to 0. 8 microns and a transmittance at some wavelength in the wavelength range between about 0. 2 and about 0. 4 microns of at least about 86 percent and a porosity of less than about 0. 001 percent. The sintered body is produced by a two-step method comprising forming a closed porosity body from a spinel powder and subjecting the closed porosity body to a hot isostatic pressure treatment. The resulting body has high transmissivity of electromagnetic radiation in the range between about 0. 2 microns and about 6 microns, is resistant to abrasion or erosion, does not substantially deteriorate after exposure to ultraviolet light, and has high strength. A number of applications of the magnesia-alumina spinel body are disclosed for which the material is advantageous.

  • International Classification:
    C04B 3502
  • US Classification:
    501120
  • Abstract:
    A method for producing a transparent polycrystalline magnesia-alumina spinel body having high ultraviolet transmissivity and high strength and hardness characteristics is provided. A closed porosity body is formed from a spinel powder preferably having at least minimum purity characteristics. The closed porosity body can be formed by techniques including hot pressing and pressureless sintering. The closed porosity body is subjected to a hot isostatic pressure treatment to reduce residual porosity. The resulting body has high transmissivity of electro-magnetic radiation in the range between about 0. 2 microns and about 6 microns and is resistant to abrasion or erosion, has high strength, and does not substantially deteriorate after exposure to ultraviolet light.
