  • High porosity titania-zirconia catalyst support prepared by a process
    Patent number: 5021392
    Abstract: This invention relates to catalyst supports, methods for making them, and to catalysts prepared therefrom. More particularly, it relates to binary oxidic catalyst support materials comprising titania and zirconia with high porosity and high surface area prepared by either a pH swing technique or a constant pH technique followed by calcination at a temperature below 450.degree. C., with such materials being impregnated with catalytically active metal components.
    Type: Grant
    Filed: June 14, 1990
    Date of Patent: June 4, 1991
    Assignee: American Cyanamid Company
    Inventors: Francis P. Daly, Hiei Ando, Henry C. Foley, Hyun J. Jung

  • Articles comprising metal-coated polymeric substrates and process
    Patent number: 4783243
    Abstract: Improved articles are disclosed having a polymeric substrate containing a polymer, such as polyamide, and a metallic sulfide, such as copper sulfide, and a thin, uniform, and firmly adherent overlayer of an eletrodepositable metal, such as nickel. The metal overlayer may be continuous or selectively patterned over the polymeric substrate. The metal layer provides the articles with decorative, protective and electrically conductive characteristics without significantly diminishing polymeric properties.
    Type: Grant
    Filed: December 18, 1986
    Date of Patent: November 8, 1988
    Assignee: American Cyanamid Company
    Inventors: Hiei Ando, Dale E. Hall
  • Oxidation catalyst and use in the production of anthraquinone
    Patent number: 4215063
    Abstract: Anthraquinone is prepared by the oxidation of diphenylmethane compounds in the gas phase in the presence of vanadium (V) oxide and a metal selected from ruthenium, rhenium, cerium, niobium and rhodium, and optionally a third metal selected from manganese, barium, cerium and iron.
    Type: Grant
    Filed: May 3, 1979
    Date of Patent: July 29, 1980
    Assignee: American Cyanamid Company
    Inventors: Joseph L. Schmitt, Jr., Hiei Ando
  • Coating of cadmium stannate films onto plastic substrates
    Patent number: 4048372
    Abstract: Light transmissive, electrically conductive cadmium stannate films on plastic substrates are greatly improved with respect to their adherence to the substrate if the film is deposited on a substrate which has been precoated with a metal oxide, such as silicon dioxide or titanium dioxide.
