Abstract

Short fine rods of antimony are soldered to one end of a fine silver wire which is then coated with a plastic sheath for insulation and stiffening purposes. The antimony and silver wire electrode is supported vertically with the antimony uppermost and the liquid resin is applied at the sides of the distal end of the antimony and flows down covering the antimony and silver wire but leaving the tip face of the antimony exposed. This process eliminates micro crevices between the resin and the antimony tip.

Claims

2. The method according to claim 1 in which said rod and said wire are of similar diameters and are in end to end relationship one with the other.

3. The method according to claim 1 in which said assembly is supported by inserting the upper end of said silver wire into a supporting surface.

4. The method according to claim 2 in which said assembly is supported by inserting the upper end of said silver wire into a supporting surface.
