Abstract

465,406. Motor generators. THOMAS, A. R. Oct. 3, 1935, No. 27288. Drawings to Specification. [Class 35] [Also in Group XXXVIII] To produce current of constant voltage a magneto, preferably of the rotary magnet type, is driven by a synchronous motor supplied from a source of constant frequency, either a mains system or a direct-current with a tuning-fork interrupter.
