Title: Display device for producing polychromatic luminous image
IPC: H01J17/49
Filed: 1975-09-12
Abstract: 1515319 Matrix displays THOMSON-CSF 12 Sept 1975 [13 Sept 1974] 37681/75 Heading G5C [Also in Divisions H1 and H4] A gas discharge display panel comprises, between the groups of electrodes, one or more photoconductive elements which is or are made locally conducting by invisible scanning radiations. As described a glass substrate 8 supports a transparent tin oxide electrode 2, and a layer 3 of photoconductive zinc oxide whose resistance is reduced to a third when subjected to UV radiation such as is emitted from the screen of c.r.t. 30. The UV is focussed on to a localized area of layer 3, preferably covering three luminophores 6, so causing localized gas discharge and glow of luminophores 6, which may be excited by electrons, or the UV radiation accompanying the discharge. The potential across corresponding electrodes originates from supply 20 but is modified by modulators 21-23 so that the intensity of colour is controlled. The space between the electrodes may be filled (Fig. 2, not shown) by a dielectric matrix having gas-filled holes at the intersections of the strip electrodes 7 and the scanning lines. In an alternative embodiment (Fig. 3, not shown) the colour modulation voltages are applied to thin film electrodes deposited on the free surface of the luminophores and the corresponding electrodes 7 are connected to the supply voltage through switches (37-39). Electrode 2 may be a continuous sheet or a network of strips running perpendicular to electrodes 7, and luminophores 6 may be strips or discrete elements at the intersections of said network and strips 7. The c.r.t. may be replaced by a mechanically deflected U.V. lamp or an acousto-optically or electro-optically deflected laser beam.

IPC: C01G49/10
Filed: 1966-09-01
Abstract: Ferric chloride is extracted from an aqueous solution containing FeCl3 and AlCl3 in which the chloride ion concentration is 80-200 grams/litre by contacting the solution with a solution of a quaternary ammonium halide [R1R2R3R4]+ [X]- in an inert non-polar organic liquid, (wherein R1, R2, R3, R4 each is alkyl, alkenyl, aryl, or aralkyl and X is halide, and separating the organic and aqueous phases.  The organic solution preferably contains also 3-25 vol. per cent of one or more aliphatic alcohols containing 8-16 carbon atoms as an emulsion inhibitor. The organic radicals of the quaternary ammonium chloride preferably contain an aggregate of 12-60 carbon atoms, and each radical may contain 1-20 carbon atoms. The ferric chloride may be stripped from the separated organic phase by contacting the latter with an aqueous liquor containing less than 25 grams/litre of chloride ions, and separating the aqueous and organic phases.  In the example, calcined Georgia clay was leached with HCl, giving a liquor containing AlCl3 and FeCl3.  This was contacted at room temperature with an organic solution containing 5 vol. per cent tricaprylyl monomethyl ammonium chloride, 10 vol. per cent n-decyl alcohol and 85 vol. per cent kerosene, such that the organic/aqueous volume phase ratio was 2:1.  After separation, the aqueous phase contained 0.0004 grams/litre of Fe2O3 (as FeCl3) and the organic phase 1.35 grams/litre.  The organic phase was subsequently contacted with an HCl solution containing 10 grams/litre of chloride ion to extract the FeCl3.

Abstract: 1286131 Rolling WESTINGHOUSE ELECTRIC CORP 6 Aug 1969 [27 Aug 1968 14 Oct 1968] 39335/69 Heading B3M A method and apparatus for operating a slabbing mill having work rolls 18, 20 and edger rolls 52, 54 comprises computing a schedule of rolling passes based on details of an ingot to be rolled and comparing the rolling loads and rolling torques obtained during actual rolling with values predicted in the schedule and increasing or decreasing the number of roll passes so that a final slab size is produced in the fewest passes within the mill constraints. The mill comprises an entry roller table 28 and a delivery roller table 36, the rollers of which are driven by motors 30 and 40 having speed sensors 33, 41 and control means 34, 42 respectively. The motors 22, 24 for the rolls 18, 20 have each a control means, speed sensor and voltage and current measuring devices. The latter give the measure of the rolling torque and rolling horsepower which are compared with predicted values for the schedule. The motors for the edger rolls have similar means associated with them and the edger roll speed is arranged so that these rolls do not contribute to the speed of the ingot through the mill. Means 46 on the delivery table side are used to turn the ingot on to its edge from its face and vice versa. An ingot to be rolled is first rolled in edge scale breaking passes through the main mill rolls 18, 20 and then turned on to its face for a series of flat roll passes. The edger rolls are used on the final odd pass, passes from entry to delivery side being odd others being even, and on even passes before that as few passes being used for edge rolling as possible. If the width of the final slab cannot be met by edge rolling on even passes only then odd passes are also used, starting from the next to last up to the first. If these are insufficient the ingot can be turned on edge in a turn-up edge pass through the main mill rolls. The schedule is calculated and updated by means of a digital computer.
