Abstract

931,862. Transformers. PLESSEY CO. Ltd. April 14, 1960 [April 2, 1959], No. 11193/59. Class 38 (2). A radio-frequency transformer has a core comprising a pot-like outer core part of ferrite and an inner ferrite core rod 4 (Fig. 4) mounted on a base 1 and adjustable longitudinally in the outer core part which is carried in one end of a plastics sleeve 6 (Fig. 1) by screwing the threaded stem 2 into the other end of the sleeve 6 which is slit at 7.
