476,513. Soldering electric terminals. KLEINMANN, E., and MENDEL, A. July 16, 1936, No. 19776. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] In order to confine to a limited area the solder employed to attach a lug 3 to a metal cap 1, such as those used for capping carbon electrodes, the required area is either formed as a depression, or is roughened. The depression 2, Fig. 1, extends only part-way through the thickness of the cap 1. If a roughened area 4, Fig. 3, is employed it retains the solder upon it. |
