Abstract

827,506. Transformers. LONDON, PRINCIPAL SECRETARY OF STATE FOR FOREIGN AFFAIRS OF. Sept. 27, 1957 [Sept. 28, 1956], No. 29631/56. Class 38 (2). A radio frequency transformer comprises a primary winding P formed from a copper tape 2 attached to a polystryrene tape 8 by transparent adhesive tape 10 wound on to the centre rod 6 of Ferroxcube pot core assembly and a secondary winding S wound as a helical winding coaxial with winding S and insulated therefrom by part of the tape 8. An electrostatic earthed screen 14 may be interposed between the two windings, or the outer turn of the primary winding may be earthed. The windings are surrounded by the pot-type core which may be potted in resin or contained in moulded polythene.
