Abstract

853,888. Radio receiver switch tuning arrangements. FUJI TSUSHINKI SEIZO KABUSHIKI KAISHA. July 6, 1959 [July 15, 1958], No. 23173/59. Drawings to Specification. Class 40(5). In an oscillator tuning circuit for television receivers, a plurality of inductors, some of which are variable, are arranged in groups, the inductors of each group being connected in series and having a tap connected to the junction of each pair, engageable by a movable tap, the arrangement being such that when any inductor is varied solely the inductance of its particular group is affected.
