Abstract

799,682. Inductors. N.S.F., Ltd. (Oak Mfg. Co.). Sept. 22, 1955 [June 22, 1954], No. 18269/54. Class 38 (2). [Also in Group XL (c)] High - frequency electrical apparatus comprises an inductive element 1 of silverplated sheet metal which has a plurality of slots 2 therein extending from an edge of the element 1, the inner end of each slot being enlarged into a circular opening 3. The element may form part of the tuning apparatus for television receivers, the tuning being effected by means of a switch, the contacts of which are secured to the element between the slots by means of apertures 4. Specification 779,553, [Group XL (c)], is referred to.
