Abstract

738,297. Rectifying. STANDARD TELEPHONES & CABLES, Ltd. Oct. 24, 1952 [Nov. 3, 1951], No. 26736/52. Addition to 738,266. Class 38 (2). [Also in Group XL (c)] An electromagnetic deflection coil arrangement according to the parent Specification has the line deflection coils AS connected in the anode circuit of an electron discharge tube R, an efficiency diode D being connected in parallel with the coils AS, the coil circuit being completed by a capacitor network N. Such a circuit allows a lower battery voltage to be used whilst the E.H.T. is generated by a voltage doubling circuit SP from the energy in the line deflection coils AS during the fly-back stroke.
