Title: Circuit arrangement for the simultaneous display of the instant aneous values of two or more time-dpeendent variable electric  signals
IPC: G01R13/40
Filed: 1974-07-19
Abstract: 1450483 Control of displays MECHANIKAI LABORATORIUM HIRADASTECHNIKAI KISERLETT VALLALAT 19 July 1974 [3 Aug 1973] 32065/74 Heading G4H [Also in Division H3] Two signals G2, G1, are represented simultaneously on a matrix display M in quantized analog form as a selected column having a particular height. As described, the display consist of light emitting diodes. Signals G1, G2 are respectively compared in comparators KS, KO with reference voltages R, R<SP>1</SP>, a "0" logic level being produced when the input signal exceeds a reference voltage. The outputs from comparators KS are inverted by the driver circuitry TS &c. whereas the outputs from comparators KO are fed to XOR gates E to produce just one "0" level output (this is not inverted) to select a column whose position in the matrix corresponds to the instantaneous value of G2. The "1" outputs from TS, &c. cause a number of diodes in the selected column to be illuminated: thus a displayed column is produced whose height corresponds to the instantaneous value of G1. If signal G2 is varying (e.g. a square wave signal) then the selected column will alternate according to its frequency: the persistence of vision effect causes the two columns to be displayed in effect simultaneously, the distance between the columns depending on the amplitude of G2. Another variable may be displayed using change in illumination, colour, &c. of the diodes. The reference voltages R, R<SP>1</SP> may be arranged in equal steps or, e.g. in a logarithmic progression.

Abstract: 947,464. Automatic control systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 24, 1962 [Aug. 29, 1961], No. 32647/62. Heading G3R. Apparatus for automatically controlling the current density in an electrochemical bath includes a variable voltage power source having constant voltage and constant current control means, and means whereby, when a workpiece is immersed in the bath, the constant voltage control adjusts the voltage across the bath to a preselected value corresponding to a selected current density, and means which thereafter switches over to constant current control so as to maintain the current through the bath at the value existing just prior to switch over. As shown, a bath represented by a load 5 is supplied from A.C. input terminals 1, 2 over a transformer T, a regulator 4, a rectifier 3 and an ammeter A. The voltage across the bath is compared with a pre-set voltage appearing at the slider 8 of a potentiometer 9, initial setting of the slider 8 for a chosen current density being effected by immersing a test sample of known area in the bath. When a workpiece of unknown area is immersed in the bath a difference voltage is applied to a control amplifier 12 the output from which is applied to the regulator 4 so that the bath voltage is held at such a value that the current density is as chosen. A current-dependent voltage V derived from a pick up coil 13 and means 14 is applied to a potentiometer 15 and a potentiometer 15 and a portion thereof constituting a control voltage which appears at the slider 16 is compared with a second pre-set voltage appearing at slider 17 of potentiometer 18, any difference voltage being applied to a detector 23 the output from which energizes a motor 24 which drives slider 16 until equality is reached. When this happens a relay RL operates to disconnect amplifier 12 from the first pre-set voltage source and to connect it to slider 16. The apparatus then operates under constant current conditions. A further potentiometer 26 having a slider 25 also connected to the amplifier 12 enables the apparatus to operate at a different desired current density.
