Abstract

209,067. Siemens Schuckertwerke Ges. Dec. 23, 1922, [Convention date]. Speed maintaining systems. - A direct-current motor 1 having a field winding 2 is automatically regulated for constant speed by causing the grid 6 of a thermionic valve 4, 5 placed in shunt to the motor field winding to be acted upon by a tachometer dynamo opposing an adjustable battery potential. The dynamo and battery are not shown in the Figure. Specification 234,146 is referred to.
