Title: Improvements in electric control systems
Inventor: OLAH GEORGE
IPC: G05B11/01
Filed: 1950-10-02
Abstract: 683,571. Automatic control systems. ELLIOTT BROTHERS (LONDON), Ltd. Aug. 30, 1951 [Oct. 2, 1950], No. 24066/50. Class 38 (iv). In a system for automatically controlling a variable, a direct voltage corresponding in magnitude and polarity to the magnitude and sense of deviation of the variable from a desired value is applied to a polarized relay which operates to a predetermined deviation to actuate means correcting the variable, an additional winding on the relay provides adjustable bias and relay operation is automatically assisted when the relay operates. In a system for maintaining a variable between predetermined limits, Fig. 1, a potentiometer slider 5 associated with a D.C. source 2, 3 moves in a direction corresponding to the sense of deviation of the variable and to an extent depending on the magnitude of the deviation. A voltage of corresponding polarity and magnitude is thus produced which is applied to windings 7 and 10 of oppositely polarized (core or moving coil) relays 6 and 9, one of which operates, if the deviation is large enough, to energize through contact 29 or 30 the appropriate section of the split field winding 26 of a reversible servomotor (not shown) which then runs in the direction required to correct the variable. In order to preset the magnitude of deviation required to operate the relays a rheostat 16 controls the current through relay biasing windings 12 and 18 which oppose windings 7 and 10. To ensure positive operation of the relays, auxiliary contacts 22, 24 open, when the associated relay operates, to decrease the current in the associated biasing winding. Alternatively the auxiliary contacts may decrease the biasing current when they close upon operation of the relays. A single relay arrangement in which the servomotor is switched on or off when the deviation exceeds one limit only is referred to. Arrangements in which two or more sets of relays operate at different deviation magnitudes are also referred to. In a modification, Fig. 2 (not shown), relays 6 and 9 control additional less-sensitive relays which control the servomotor.
