Abstract

1452098 Inductors RCA CORPORATION 21 Dec 1973 [12 Jan 1973] 59558/73 Heading H1T [Also in Division H3] An inductor, whose inductance changes with the direction of current in its winding, comprises a former 50 bearing a winding, the former having a recess into which extends a combination of a magnetically permeable core member and a permanent magnet, the magnet being magnetized to have both poles on a surface disposed adjacent the core member. As shown the magnet 53 may be barium ferrite and the core member 54 may be a saturable ferrite. The combination may be press fitted into the recess completely or partially Fig. 7 (not shown) and bonded in place with epoxy resin. Terminals 52 may be used for connexions to a circuit board (not shown). The inductor may be used in TV scanning linearity circuits described, for example, in U.S. Specification 3452244 (see H3T).
