Abstract: 1314049 Modulating light IMPERIAL CHEMICAL INDUSTRIES Ltd 18 Nov 1971 [8 Dec 1970] 58278/70 Heading H4F [Also in Division C3] A layer 5, comprising an N-(p-cyanophenyl) substituted derivative of a compound having two conjugated nitrogen containing aromatic rings, is disposed between a glass plate 7 and a working electrode 2 and in contact with a counter electrode 6 so that in use the soluble, colourless or pale yellow derivative may be reversibly reduced at electrode 2 to the insoluble coloured (usually green) radical. The electrode 6 is disposed so that reactions occuring thereat do not materially affect the passage of light incident on layer 5, and preferably obstructs at most only 10% of the working area. As shown, electrode 6 is a platinum or copper wire outside the working area, which changes colour uniformly, but it may be a shaped wire or grid in the working area, if the resistance of layer 5 is sufficiently high, to display corresponding characteristics, e.g. alphanumeric. The electrode 2 (and base 1) may be transparent (oxide or metal), or it may be reflective (metal) or be provided with a further reflective layer. Materials suitable for layer 5 include mono- and di-N-(p-cyanophenyl) derivatives of bipydridyls, diazapyrene and biquinolines, and particuarly N,N<SP>1</SP>-di(p-cyanophenyl)-4,4<SP>1</SP>-bipyridilium salts, and the product of quaternising a 4-(4<SP>1</SP>-pyridyl)N-p-cyanophenyl pyridium salt with the chloroacetate groups of polyvinyl chloroacetate or copolymers of vinyl chloroacetate and vinyl alcohol. Cross-linking of the latter with glyoxial gives a gelled material. The material is usually used in the presence of water or a water soluble polymer, and inert electrolytes. An easily oxidized material which is soluble and only lightly coloured in both oxidation states, such as sodium ferrocyanide, may be added to catalyse the main redox reaction. The reaction at the electrode 6 may be identical to that at electrode 2, i.e. deposition and removal of the radical, in which case it should have at least 1 % of the working area of the device and is preferably pre-coated with the radical compound, or it may differ therefrom, e.g. a silver/silver chloride,electrode if the anions of layer 5 are also chloride. A third, reference electrode, e.g. Ag/AgCl/staturated KCl may beincorporated for controlling the potential applied to the device.

Abstract: 1345869 Measuring direct current DEFENCE SECRETARY OF STATE FOR 30 Nov 1971 [30 Nov 1970] 56771/70 Heading G1U In order to measure the direct current i 3 , Fig. 5, through a line L 3 , a magnetic core M is cyclically driven around its hysterisis loop by a multivibrator comprising transistors Q 1 , Q 2 , and oppositely wound coils L 1 , L 2 , and the difference in the average currents through the two transistors Q 1 , Q 2 , is measured, this being a measure of the unknown current i 3 . This arises because in the absence of current i 3  in the line L 3 , a potentiometer RV is adjusted so that the conduction pattern of the transistors Q 1 , Q 2  is symmetrical, and therefore a voltmeter R5, A, reads zero, whereas once a current i 3  is present the conduction pattern becomes asymmetrical to an extent which is proportional to i 3 . In a modification, rather than the asymmetry being determined by an averaging-volt meter R5, A, a voltage representing the asymmetry is derived by a filter F and an amplifier Da, Fig. 7, and used to apply a compensating current i 4  to the core in a direction which opposes i 3 . In a further modification Fig. 6, (not shown), an additional core (M') is coupled to the line L 3  and windings on it are energized in such a way as to cancel signals induced in the line by the main core. Range changing may be effected either by taps on the coils L 1 , L 2 , Fig. 5, Fig. 7, (the taps not being shown) or by taps on the compensating winding.
