Title: Position transducers for servo- drives
IPC: G01D5/14
Filed: 1980-11-18
Abstract: A position transducer in which a sensor moves between two terminal points of a path uses the movement of the sensor to set at least one of the terminal points at the maximum displacement of the sensor in that direction. For example, a slider 28 of a potentiometer is coupled to the motor 32 of the servo-drive via intermediate elements 30. The terminal connectors 34, 36 of the potentiometer are displaceably arranged on the resistor member 26 of the same so that they are pushed away from each other by the slider 28 during its very first displacement, and then remain at these positions. A system of this nature results in an automatic adaptation of the position transducer to the path length of the sensor coupled to the servo-drive. The transducer can be a differential capacitor, a differential inductor or a photodetector variably shielded from a light source. <IMAGE>

Abstract: The control slide 5 of a control valve 2 is adjustable with the aid of a mechanical remote control device 3. The latter has a manually actuated lever 34 and a pulling means in the form of a cable 39 coupled to the lever. The cable is connected to the control slide 5 and a return spring 6 additionally engages the control slide in such a manner that the cable is permanently under tension. The control valve 2 is arranged so that the control slide 5 can be moved by the return spring 6 into an emergency switching position adjacent to the positions designed for controlling an hydraulic drive 18 if the cable should rupture. In the said emergency switching position, the control slide 5 effects the stopping of the hydraulic drive 18. The control valve, Fig. 2 (not shown), has neutral, lower, raise float and emergency control positions. The control valve and actuating lever 34 are normally biased to neutral by a resetting mechanism 36, having one or more springs. The actuating mechanism comprises a spring pressed detent 37 which is releasable by electromagnet 75 on either pressing a bolt on 71 to actuate a switch 70 or by limit switches 25, 26 on the hydraulic drive 18. Electromagnets 15 of a flashing unit 14 preventing conitation are actuated by switch 78. <IMAGE>
