Patent GB-800560-A (GB)
Title: Electrical control apparatus
IPC: G05B11/01
Filed: 1956-05-02
Abstract: 800,560. Automatic temperature control systems. BARBER-COLMAN CO. May 2, 1956 [May 3, 1955], No. 13589/56. Class 38 (4). In a system for automatically controlling a variable, a reactance, varied in response to changes in the variable, is included in the gridcathode circuit of an oscillator valve which has two tuned circuits in series between grid and cathode, the anode load, which controls the variable, being connected to the junction between the two tuned circuits. In Fig. 1, when the temperature of an electric furnace 10 is below a predetermined value the anode current of a thermionic valve 21 energizes an electromagnetic relay 13 so that the furnace heater resistance 11 is supplied with current from an A.C. source 29. As furnace temperature rises the increased energization of a moving coil 16 from a thermocouple 15 moves an aluminium flag 17 towards an inductance 18 so that the reactance of the latter is decreased until at the predetermined temperature the tuned circuit which it forms with a condenser 37 in the gridearth circuit of valve 21 is so tuned relative to a second tuned circuit including an inductance 38 in the cathode-earth circuit of valve 21, that valve 21 oscillates and the reduction in anode current brought about by self bias developed by resistance-capacity network 32, 33 causes operation of relay 13 to switch off heater 11. Thereafter the predetermined furnace temperature is maintained by intermittent operation of relay 13. The time constant of network 32, 33 is such that oscillations only occur over a minor portion of each half-cycle of A.C. source 29 so that the repulsion effect between flag 17 and inductance 18 is reduced. Sensitivity of control is adjustable by a variable feedback capacity 41 between grid and cathode of valve 21. A circuit through a high resistance 42 is provided to ensure that valve 21 is biased to de-energize relay 13 and switch off heater 11 if the leads to inductance 18 become open-circuited. Capacity instead of inductance variable with furnace temperature is referred to. In a modification, Fig. 2 (not shown), inductance 38 is formed in two capacity-paralleled sections, one in each of the heater leads of valve 21, so that the cathode of valve 21 may be connected to its heater to avoid switching on of the furnace heater upon heater-cathode breakdown. In another modification, Figs. 3 and 4 (not shown), changeover contacts on relay 13 are associated with electrically heated ambient temperature-compensated bimetallic strips which move an aluminium slug relative to inductance 38 to produce a time-delayed feedback effect to eliminate hunting.
