Abstract

906,125. Automatic temperature control systems. RHEOSTATIC CO. Ltd. Oct. 30, 1958 [Nov. 22, 1957], No. 16063/62. Divided out of 906,124. Drawings to Specification. Class 38 (4). The subject-matter of this Specification is similar to that described in Specification 906,124 but the claims are concerned with a feedback signal proportional to the first derivative of a voltage representative of the position of a regulating unit, this feedback signal being applied to a direct current amplifier in opposition to a direct current error signal which is dependent upon the measured and desired values of a physical quantity be controlled by the regulating unit.
