Abstract
900,906. Making magnetic heads. EPSYLON RESEARCH & DEVELOPMENT CO. Ltd. Nov. 7, 1960 [Nov. 12, 1959], No. 38374/59. Class 83 (2). [Also in Group XXXVIII] The core of a magnetic head is made from work-sensitive magnetic alloy. Strips 16 are sheared, Fig. 1, from a coil 11, and their ends are ground in a fixture 18 at a slight angle, such that when bent into a closed loop, the ground faces are in parallel confronting relationship at 26. The strips are bent into open rings 19 and held in a fixture, Fig. 5, which maintains their shape during an annealing process which restores the magnetic properties. The rings are then copper-plated so that on closure a non-magnetic gap of predetermined thickness is formed at 26. A former-wound coil 23 is so proportioned that the closure of the ring 19 does not seriously upset its magnetic properties. The ring may be held closed by non-magnetic clips, by encapsulation or both.
