    摘要: A flat scale indicating device for use with servo units having feedback loops, having an indicator arm pivotally mounted to a sector gear, the latter being in meshing engagement with a rotary pinion for transmitting rotary motion of the pinion to a straight line translatory motion at the pointer end of the indicating arm. The indicator arm further functions as a potentiometer wiper and an electrical connection is provided between the arm and a suitable amplifier bridge circuit.

    摘要: A variable capacitance transducer has a cable loop interlinked with a metallic tube. The cable loop comprises a metallic cablehalf joined to an insulative cable-half. The portion of the cable loop passing through the metallic tube is axially positioned in the tube and a capacitive element is formed by the metallic tube and the metallic cable-half. Displacement of the cable loop to vary the amount of the metallic cable-half inside the metallic tube varies the capacitance of the capacitive element in a linear manner.
