Title: Measuring devices
IPC: G01R1/20
Filed: 1966-01-17
Abstract: 1,125,374. Variable resistor measuring device. D. C. GALL. 14 Dec., 1966 [17 .Jan., 1966], No.2117/66. Heading H1S. A measuring device for use in connection with a resistance bridge has a resistance wire spirally wound on the surface of a solid of revolution, the diameter of which varies along its axis approximately inversely as (X + 1)<SP>2</SP> where X is a positive number, and a slider which moves along the wire when relative motion takes place between the two. The resistance wire 2, Fig. 1, is spirally wound in a groove in drum 1, contact with the wire being made by a slider 8 which is caused to move along an arm 6 by projection 9 running in a spiral groove 4 in the drum surface when the drum is rotated. Various configurations of drum can be employed according to the law of resistance variation required. The complete measuring device, Fig. 3, for use as the slide wire of a Wheatstone bridge has two slide wires 2 mounted on separate conical drums 11, 12, each of different taper but on a common shaft 13, each wire having a slider 10. The drums are rotated by knob 20 via the gears 16 and 17, the shaft 22 to which the knob is fixed carrying a cylindrical roller 25 whose upper surface engages ball 26, itself engaging ball 27 running on the surface of disc 28, the combination forming a mechanical divider driving the scale of the divice. The divider can be varied by rotation of knob 33 which moves the balls 26, 27 along the surface of disc 28 perpendicularly to its axis. In this way the scales 38 and 40 are variable exactly as required between set limits, in this case over a range of 1 : 6. The value of the divider ratio can be read from counting unit 48 driven by the knob 33 used to vary the ratio. The balls 26, 27 can be released from contacting disc 28 by depression of button 54 so that the scales may be reset to zero by knobs 36 and 43. A drive wire 56 operates a counter to indicate the position of contact 10 on the slide wire. In use one slide wire is connected between the two resistance arms of a bridge, the other arms of the bridge forming a dummy gauge and an active gauge, the slider 10 being connected to a galvanometer across the diameter of the bridge.
