  • Thermocouple with overlapped dissimilar conductors
    Patent number: 5167723
    Abstract: A method of forming printed circuits on an insulating film comprising the steps of forming a panel plating layer, plating the circuits onto the panel plating layer, applying a film to the plated panel plating layer and chemically removing the panel plating layer. In addition, the printed circuit is impressed into the film so as to form a planar surface and a protective film is placed over the film and impressed circuit. The method of making a thermocouple by this process is also disclosed.
    Type: Grant

  • Electroplating apparatus with ventilation means
    Patent number: 4592819
    Abstract: A ventilating system for a high speed electroplating apparatus having a pretreating section, a plating section and a post treating section for electroplating a workpiece sequentially transferred from each section by a conveyor. Each section has a cover which together completely enclose the apparatus except for inlet and outlet areas. An exhaust fan is positioned in a duct connected to the enclosed treating sections for exhausting the accumulated gases to the atmosphere outside the work area.

  • High speed plating apparatus
    Patent number: 4543172
    Abstract: High speed plating apparatus in which a cylindrical electrode structure has fitted into it a metal tube. The metal tube has a higher melting point than the electrode, is corrosion resistant to plating liquid and protects the inner surface of the electrode.
