Abstract
528,935. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. May 17, 1939, No. 14733. Convention date May 17, 1938. [Class 38 (iv)] Voltage &c.-An automatic regulating system comprising a switch 9 whereby automatic or manually operable means 6, 5 for effecting raising or lowering actions may be selectively rendered effective, has additional contacts on the switch whereby both means are simultaneously energized to permit testing of the regulator and checking of the values and -the regulated quantity at which the automatic relay operates. The Figure shows an induction volutage regulator system.
