  • 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

    Inventors: Hiei Ando, Dale E. Hall
  • Patent number: 4737249
    Abstract: A process for the electrochemical production of hydrogen from an aqueous alkaline electrolyte characterized by the use as a cathode of a material having the general formula AB.sub.5 H.sub.x wherein A is one or more of rare earth metals and calcium, B is nickel or cobalt and x is a number, generally from 4 to 8 characteristic of saturation of the AB.sub.5 -compound with hydrogen. The hydrogen is generated at a relatively low overpotential and thus at high efficiency.

  • Patent number: 4410413
    Abstract: A cathode for use in the electrochemical production of hydrogen and process for making it which involves direct electrochemical cathodic action on a thermally produced adherent oxide on a nickel cathode surface. Examples include a nickel sheet thermally oxidized in air at 600.degree. C. for one hour and used directly in the production of electrolytic hydrogen and an iron sheet plasma sprayed with nickel to provide a surface containing thermal oxidation product of nickel and again used directly in the electrolytic production of hydrogen.

  • Patent number: 4253919
    Abstract: A process for electrodepositing cadmium and selenium onto a material suitable for use as a photoelectrode in a photovoltaic cell. The plating electrolyte, in one embodiment, consists essentially of an acid citrate bath including hydrated citric acid, hydrated sodium citrate, hydrated cadmium chloride and selenious acid. The deposit may be subsequently heat treated.
