Abstract

904,443. Converting. MULLARD Ltd. March 21, 1960, No. 9898/60. Addition to 821,517. Drawings to Specification. Class 38 (2). [Also in Group XL (c)] A sawtooth wave generator of the type described in the parent Specification and more particularly with reference to Fig. 5, thereof, uses a silicon controlled rectifier or other PNPN transistor and is provided with an additional winding from which a D.C. E.H.T. voltage may be derived.
