Abstract

342,630. Grinding or disintegrating wood. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Rogers, H. W. ; 10, Parkwood Boulevard, Schenectady, New York, U.S.A.) May 27, 1930, No. 16318. Convention date, May 27, 1929. [Class 59.] A motor 22 feeding material to a grindstone 10 of a magazine pulp grinding machine, is controlled according to the load on the synchronous motor 12 driving the grindstone. The control device comprises a synchronous dynamometer 27 which determines the lag between the rotor and stator fields of the motor 12 and adjusts the field resistance 26 of the motor 22.
