Abstract

406,250. Control of A.C. motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) May 6, 1932, No. 13128. Void [Abridged as open to inspection under Sect. 91 of the Acts May 7, 1932]. Drawings to Specification. [Class 38 (iii).] The Specification relates to the control of motors the rotors of which are supplied with A.C. and the fields with either A.C. or D.C. The rotor supply is controlled by grid control electron discharge devices arranged so as to connect the supply which may be either D.C. or A.C. into variable frequency A.C. Specification 386,976, [Group XXXV], is referred to.
