  • Patent number: 7850832
    Abstract: The present invention relates to an inert, non-asbestos separator and method of making same, the separator comprising an inorganic/polymer fibrid and agglomeration composite material containing from about 5 weight percent to about 70 weight percent of organic halocarbon polymer fibers together with from about 30 wt percent to about 95 weight percent of a finely divided non-organic particulate, which non-organic particulate is firmly bound in said composite fibrids and agglomerates; a natural gum thickening agent in an amount to provide a viscosity of about 6270 to about 590 cP at 0.22 sec?1; and an inert inorganic particulate powder whereby the inert inorganic particulate remains unbound from the inorganic/polymer fibrid and agglomeration composite, the inorganic particulate powder having a mean particle size of not greater than 1.0 ?m and being present in an amount to provide a ratio of polymer fiber composite to unbound inorganic particulate in a range from about 1 to 25.
    Type: Grant
    Filed: September 7, 2006
    Date of Patent: December 14, 2010
    Assignee: Industrie de Nora S.p.A.
    Inventors: Nick J. Tomba, Michael S. Moats, Richard L. Romine, Thomas F. Florkiewicz, Douglas J. Waskovich, Edward S. Kazimir

  • Patent number: 6051117
    Abstract: An apertured and porous metal article can find use, for example, in diaphragm or membrane electrolysis cells. The article may comprise a thin and flexible metal foam of small pores which, typically, has been perforated with large apertures. The article may also be provided with an electrocatalytic coating. It can be in substantial physical contact with a membrane or diaphragm separator used in the cell for separating anode and cathode members or compartments. There is also disclosed the preparation of the article and an electrolysis cell utilizing the resulting apertured and porous metal article.
