Abstract

789,726. Reciprocating electromagnets. WEAKE, V. G. P., and SEMARK, F. R. Nov. 11, 1955 [Nov. 11, 1954], No. 32734/54. Class 35. The moving coil 11 of a reciprocating electromagnet is located in the annular air-gap 5 by means of a spigot 13 sliding in a bearing sleeve 14 lined with polytetrafluoroethylene 15. The pole faces are copper-plated at 42, 43 as described in Specification 789,725.
