Abstract

398,412. Speed governors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Caughey, R. J. ; 910, Livingston Avenue, Schenectady, New York, U.S.A.) Feb. 24, 1933, No. 5719. Convention date, Feb. 25, 1932. [Class 57.] A control system, shown as a speed governor controlling a valve, but may be responsive to load, frequency, voltage, &c., comprises a control valve 13 controlling fluid to a power cylinder 6. The follow-up mechanism comprises a spring-loaded piston 28 connected to the floating lever 21, the cylinder 27 being supplied with fluid through an adjustable valve 31a and the amount of leak from the pipe 33 being controlled by a valve 36 actuated by the rod 4. Specification 354,458 is referred to.
