  • Retroreflective materials and methods for their production and use
    Patent number: 4756931
    Abstract: Retroreflective materials are made by coating glass particles with both hydrophobic polymers and coupling agents or with siloxane compounds which have both hydrophobic side chains and coupling-type side chains capable of chemically bonding to, or of forming loose associations with, a wide variety of materials.
    Type: Grant
    Filed: June 5, 1986
    Date of Patent: July 12, 1988
    Assignee: Potters Industries, Inc.
    Inventors: John J. Giordano, Jeffrey P. Shawcross, Alfred E. Fuchs, Robert DeJaiffe
  • Microbicidal coated beads
    Patent number: 4682992
    Abstract: Organosilicon quaternary ammonias and other microbicidal compounds are bound to the surface of discrete inorganic particles such as glass spheres. Inorganic particles coated with the microbicidal compounds are used in hospital fluidized beds, air filters, and other products in which microbicidal qualities are desired.
    Type: Grant
    Filed: June 25, 1984
    Date of Patent: July 28, 1987
    Assignee: Potters Industries, Inc.
    Inventor: Alfred E. Fuchs
  • Dansyl chloride testing method
    Patent number: 4610966
    Abstract: A method of analyzing molecular layers of amino-functional group coupling agents on inorganic substrates is disclosed. A saturated solution of 1-dimethylaminonaphthalene-5-sulfonyl chloride is added to a sample to be tested, and sufficient time is allowed, with or without heating, for the reaction of the 1-dimethylaminonaphthalene-5-sulfonyl chloride with any amino functional group coupling agent which might be present. The color intensity of the reaction product is compared under ultraviolet light in an otherwise substantially dark room with the color intensity of standards representative of known thicknesses of coupling agent to determine the existence and thickness of the coupling agent on the particles being analyzed.
