Abstract

1,067,325. Induction furnaces. O. JUNKER. June 19, 1964 [June 20, 1963], No. 25403/64. Heading H5H. [Also in Division F4] The description and drawings disclose substantially the same subject-matter as that of Specification 1,067,326, but it is additionally disclosed that adjusting screws (31) (Fig. 2, not shown), pressing through an insulating layer (32) of mica, asbestos or fireproof felt, against the C-yokes (24) allow adjustment of the radial pressure on the coil (17).
