Abstract
691,190. Systems depending on two machines. TURRINELLI. G. April 19, 1950 [April 23, 1949], No. 9651/50. Drawings to Specification. Class 38 (iv). [Also in Group XXXVII] Two mechanically coupled D.C. dynamoelectric machines are connected in series across a constant source, and the excitation of the fields is varied by gauged rheostats to obtain a variable voltage from one machine. Switches are provided to change to an ordinary motordriven booster arrangement.
