Abstract

871,567. Automatic temperature-control systems. STEGHART, F. L. F. Feb. 22, 1957 [Nov. 17, 1956], No. 35856/60. Divided out of 871,562. Class 38 (4). In an electronic automatic temperature control system temperature variations are detected by a two-part element, one part of which is sensitive and the other insensitive to temperature changes, the element forming part of, but being located remotely from, the remainder of an A.C. bridge circuit to which it is connected by three leads. In the arrangement described, which is identical with that described with reference to Fig. 4 in Specification 871,562, deviation of temperature from a desired value influences a temperature variable resistor 1 which, together with constant resistors 4 and 160, is connected to the remainder of an A.C. bridge circuit, which is located elsewhere, by three leads (shown dotted), one of which is earthed. The resulting output of the bridge circuit, balance of which is independent of the length of the leads, is applied through a transformer 163 to a phase-sensitive discriminator, the direct voltage output of which, through an electronically-operated relay circuit, runs a temperature-regulating motor 38 in the appropriate direction to correct the temperature. A potentiometer 40 operated by motor 38 applies rate feed-back through a condenser 52 to introduce an integral component of control. A disconnecting link 164 facilitates balancing of the phase discriminator.
