  • Method for selecting raw material for bleaching clay
    Patent number: 6093669
    Abstract: A process for making a bleaching clay composition useful for purification of oil is disclosed. The process involves controlled acidification of a palygorskite and smectite clay mineral with sulfuric acid. The clay mineral starting material exhibits, in an aqueous slurry, an electrical conductivity of at least about 50 microSiemens per centimeter.

  • Aqueous colloidal dispersion of fumed silica, acid and stabilizer
    Patent number: 5246624
    Abstract: An aqueous colloidal dispersion of fumed silica, acid and stabilizer, having a fumed silica concentration of at least about 40% by weight. A process for making an aqueous colloidal dispersion is also disclosed.
    Type: Grant
    Filed: January 30, 1992
    Date of Patent: September 21, 1993
    Assignee: Cabot Corporation
    Inventors: Dennis G. Miller, William F. Moll
  • Particulate absorbent material having controlled bulk density
    Patent number: 5146877
    Abstract: A particulate absorbent material is constituted by discrete clay granules and paper granules, and usually exhibits a bulk density of about 10 lbs/ft.sup.3 to about 30 lbs/ft.sup.3. The weight ratio of paper granules-to-clay granules is about 0.09 to about 9. The particle size distribution for the clay granules is relatively wider than for the paper granules.
    Type: Grant

    Assignee: Oil-Dri Corporation of America
    Inventors: Richard M. Jaffee, William F. Moll, G. Robert Goss
  • Rheological control of polyester-styrene resin compositions
    Patent number: 4240951
    Abstract: A method and composition for control of rheological properties of polyester-styrene resin compositions is provided in which a smectite is reacted with a quaternary ammonium salt to provide a desired level of quaternary ammonium salt thereon and the treated smectite is added to a polyester-styrene resin mixture to produce a desired level of viscosity.

  • Electroconductive coatings
    Patent number: 4093564
    Abstract: An electroconductive clay coating for electrophotography having solvent hold-out characteristics is provided comprising an expandable clay, an alkali metal salt, and at least one organic compound from the group consisting of sugar syrups, anionic organic compounds and fluorochemicals. In those compositions using anionic organic compounds a synergism with the expanded clay appears to result.
