  • Stub design for ESR electrodes
    Patent number: 4150247
    Abstract: An electrode for electroslag remelting is provided by combination of an ingot having a toe end with an essentially flat outer annular surface and a central protrusion together with a current-carrying stub bridging across the central protrusion and welded to the flat portion of the ingot toe end on opposite sides of the protrusion such that metal wastage and surface preparation costs for stub-to-ingot welding are avoided.

  • Metal coating by a powder metallurgy technique
    Patent number: 4102678
    Abstract: A method for coating a metal wire with a thin layer of a second powdered metal. A metal flake powder having a residual surface lubricant from a prior milling operation is placed in the lubricant holding box of a conventional draw bench. The wire to be coated is passed through the metal flake powder and drawn through a conventional drawing die to provide a green-coat wire having a mechanically adherent metal flake powder coating. The green-coat wire is subsequently sintered to metallurgically bond the coating to the wire surface.
