Abstract

963,698. Electric correspondence control systems. FOXBORO-YOXALL Ltd. May 19, 1961 [Feb. 19, 1960], No. 47755/63. Divided out of 963,697. Heading G1N. The position of a rod 1 (Fig. 1) is such that the force produced by a spring 12 compressed by the rod is equal to that from a nut 10 fixed to the rod and movable longitudinally by a shaft 7, driven by a motor 6 through a variable coupling 3. The torque transmitted by shaft 7 is linearly related to a control current in leads 37 fed into the coupling 3, and this current thus determines the linear position of the rod 1. In another embodiment (Fig. 2), the control current is fed to a coil 21 wound on a spring-biased magnetic rod 22. The flux change associated with a change in control current produces an angular displacement of the rod 22, one end of which is associated with a differential transformer 32, 33, 34, and a difference voltage is fed via amplifier 36 to coupling 3b to reposition the rod 1b .
