    Inventors: Nusrallah Jubran, Alan R. Katritzky, Josef V. Ugro, Jr.
  • Article containing microencapsulated materials
    Patent number: 4898633
    Abstract: Articles comprising a thermoplastic substrate bearing rupturable microcapsules in a binder on at least one surface thereof. These articles can be applied by means of heat and pressure to porous objects. The process of applying the articles to porous objects further results in partially embedding the microcapsules in the substrate. Thermoplastic substrates having rupturable microcapsules partially embedded therein, but not having a binder, are another aspect of this invention.

  • Selective plating by galvanic action
    Patent number: 3956528
    Abstract: A conductive substrate, particularly a pattern attached to or embedded in an insulating medium and involving nonintegral elements, is galvanically plated by contacting an exposed electrically conductive substrate (preferably in the form of a pattern) with a spray comprising the dissolved salt of a plating metal together with a powdered driving metal which is less noble than either the substrate or the plating metal, said driving metal being mixed with an inert, sprayable, particulate material, thereby resulting in the deposition of said plating metal on said conductive substrate.
