Abstract

666,477. Making electric contacts. IGRANIC ELECTRIC CO., Ltd. Oct. 15, 1947 [Oct. 19, 1946], No. 27633/47. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 17, 1948.] Class 83 (ii). An electric contact is made by spot-welding a shot 10 of silver, or other contact metal which can be coined, to a support 14. The contact metal may be shaped by a die 19, Fig. 3. The shot may be # inch in diameter and be made as in Specification 666,478, [Group II]. Instead of the dies 19, those shown in Fig. 6 of said Specification may be used. The supports 14 may be punched out before or after welding.
