Abstract

696,346. Transformers and inductances. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 26, 1951 [Nov. 3, 1950], No. 25058151. Class 38 (ii). [Also in Group XXII] In a method of making a divided wound core for a transformer or similar apparatus (see Group XXII), slits are punched across part of the width of a ribbon of magnetic material at those places where the wound core is to be divided, the marginal zones of the ribbon remaining unpunched, the ribbon is wound on to a mandrel, and the wound core cut through the unpunohed marginal zones by grinding, sawing, milling, &c.
