Melvin N. Jameson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electroless plating of nonconductive substrates
    Patent number: 4212768
    Abstract: An electroless plating catalyst prepared by reacting a tin salt in the molten state with a precious metal compound without HCl or added H.sub.2 O. The final catalyst may be a solid or a liquid at room temperature, depending on the reaction conditions, and it can be reconstituted by dilution with an appropriate aqueous solution to prepare or replenish catalytic working baths for electroless plating. Examples include the molten salt reaction of a noble metal salt with molten stannous chloride, stannous chloride dihydrate, or mixtures with other compatible materials containing either or both.
    Type: Grant
    Filed: May 5, 1975
    Date of Patent: July 15, 1980
    Inventors: Melvin N. Jameson, Gerald A. Krulik
  • Catalytically active compositions from precious metal complexes
    Patent number: 4180480
    Abstract: An electroless plating catalyst prepared by reacting a tin salt in the molten state with a precious metal complex. The final catalyst may be a solid or a liquid at room temperature, depending upon the reaction conditions, and it can be reconstituted by dilution with an appropriate aqueous solution to prepare or replenish catalytic working baths for electroless plating. Examples include the molten salt reaction of precious metal complexes with anhydrous stannous chloride or stannous chloride dihydrate.
