  • Patent number: 5340012
    Abstract: A one step ceramic brazing material preferably for use in joining ceramics to each other or in joining a ceramic to a metal. The brazing material includes a strip of a metal of alloy and greater than 3% titanium or titanium hydride in powder form, in a polymer coating thereon, to enhance the wettability of the braze metal onto ceramics and metals. The brazing material is made in the form of a coated strip so that it can be stamped to washers rings or discs for particular applications.
    Type: Grant
    Filed: April 15, 1993
    Date of Patent: August 23, 1994
    Assignee: Handy & Harman
    Inventors: Dennis Beeferman, William F. Lucas
  • Patent number: 5186380
    Abstract: A one step ceramic brazing material preferably for use in joining ceramics to each other or in joining a ceramic to a metal. The brazing material includes a strip of a eutectic alloy and greater than 3% titanium or titanium hydride in powder form, in a polymer coating thereon. The brazing material incorporates these amounts of titanium or hydride without exhibiting blushing, decreased plasticity, and brittleness in the braze joint. The brazing material is made in the form of a coated strip so that it can be stamped to washers, rings or discs for particular applications.

  • Patent number: 4082862
    Abstract: In the coating of rubber surfaces with adherent slip coatings the need for release agents is avoided by selecting as the slip coating a synthetic polymer latex composition consisting essentially of about 5 to 95% by weight of a film-forming, non-elastomeric synthetic polymer component (1) having an elongation of at least about 200% and about 5 to 95% of a normally solid, non-elastomeric, synthetic polymer component (2) exhibiting an elongation of below about 20% and a coefficient of friction of up to about 0.20, said slip coating having an elongation of at least about 200 up to 700%, a coefficient of friction of up to about 0.25 and a thickness of below about 0.005 inch.

  • Patent number: 4027060
    Abstract: An article comprising a rubber surface provided with an adherent slip coating of a synthetic polymer latex composition consisting essentially of about 5 to 95% by weight of a film-forming, non-elastomeric synthetic polymer component (1) having an elongation of at least about 200% and about 5 to 95% of a normally solid, non-elastomeric, synthetic polymer component (2) exhibiting an elongation of below about 20% and a coefficient of friction of up to about 0.20, said slip coating having an elongation of at least about 200 up to 700%, a coefficient of friction of up to about 0.25 and a thickness of below about 0.005 inch.

  • Patent number: 3967014
    Abstract: Rubber articles, such as surgeon's gloves, are provided with a synthetic resin slip coating by contacting the rubber surface with a synthetic resin latex composition. The slip coating is adherent to the rubber substrate and is very extensible without adverse effect. The synthetic resin slip coating includes from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer, and correspondingly, from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer, and vinylidene chloride-vinyl ester copolymer.
