Title: Improvements in or relating to electronic comparators
IPC: G01B7/13
Filed: 1954-08-23
Abstract: 768,723. Electric indicating and control systems. BUISSON, P. Aug. 23, 1954 [Aug. 27, 1953], No. 24505/54. Class 40 (1). A linear dimension gauge comprises a differential condenser, Fig. 1, the central plate P of which is moved about an axis 3 in accordance with the dimension, the two outer fixed plates 1, 2, of the condenser lying in planes which intersect in this axis. The capacity variations are used in any way to indicate the dimension, or for sorting articles according to their deviation from a standard size. As shown, a generator G is connected across the plates 1, 2 and the potential variations across P-2 are rectified at D, amplified at A and fed to a meter V. The generator, amplifier and detector may be combined in the form of a triode 6, Fig. 3, connected as a modified Hartley oscillator with the meter V in the grid-cathode circuit. When the moving vane P is centrally disposed between the plates 1, 2 the system just fails to oscillate, and this " zero " position is adjustable by a condenser 15. Movement of the vane P from this position by the feeler T, causes the system to oscillate for one direction of movement only of vane P, depending on the con-. nections of the plates 1, 2 to the inductance 8, so that deviations of a test object either above or below a reference dimension may be indicated at V. A relay 17 included in the anode circuit and having a biasing winding may effect a control operation. The " fixed " plate 2 may be resiliently mounted to extend the measurement range. The system may be adapted for internal measurements, Fig. 4 (not shown); the voltage peaks applied to the condenser plates 1, 2 may be removed by a gas-discharge tube connected across the inductance 8, Fig. 7 (not shown), to compensate for variations in plate and heating voltages; the meter series resistance 13 may be temperature-sensitive and indirectly heated, Fig. 8 (not shown), to compensate for variations in supply voltage; and potentials for operating indicators or con - trols through amplifiers may be taken from the points D, 9, 10. The triode may be replaced by a transistor, Fig. 10 (not shown).
