Abstract: 1504794 Thermal storage apparatus; regenerative heat transfer systems COMMISSARIAT A L'ENERGIE ATOMIQUE 19 Feb 1975 [1 March 1974 31 May 1974] 7070/75 Headings F4U and F4K A thermal storage apparatus comprises a support 2 for a thermal storage material C, e.g. a eutectic mixture, over which a heattransporting fluid F is passed in direct contact therewith, whereby when hot fluid is passed over the material, the material melts and accumulates the latent heat of fusion, and when cold fluid is passed, the material solidifies and releases heat to the fluid. As shown in Fig. 1, the material C is supported in trays 2 covered by wire-fabric elements 4 in an enclosure 2 and a gas is passed from an inlet 10 to an outlet 12 by a blower 14. In a further embodiment, Fig. 4, solid particles of the material C are supported on a filter 22 in a vessel E which communicates with a vessel E<SP>1</SP> containing material C in the liquid state, the bottom of the vessel E<SP>1</SP> being connected to the top of the vessel E by a pipe 30 containing a pump 32. In a heat storage operation, a fluid, heated in a heat exchanger C 1 , circulates in the vessel E, while melting part of the material C, and is returned to the heat exchanger by a pump 38. In a heat releasing operation, liquid material C from the vessel E<SP>1</SP> is sprayed into the vessel E where it solidifies, giving up heat to the fluid which is circulated through the vessel E and through a heat exchanger C 2 . In a modification, Fig. 5 (not shown), the fluid passes through a Venturi arrangement connected to the vessel E<SP>1</SP> whereby liquid material C may be drawn from the vessel E<SP>1</SP> and conveyed to the top of the vessel E. The material C may be a eutectic mixture of beryllium fluoride and lithium fluoride, and may be selected from the group comprising the fluorides, chlorides, oxides and hydroxides of alkali metals and alkaline-earth metals. The heat-transporting fluid may be a gas, e.g. air, carbon dioxide or nitrogen or may be a liquid selected from a group comprising water, the polyphenyls or their substituted derivatives, or from a group comprising potassium, sodium, alloys thereof, cadmium and gallium.

Title: Improvements in multi-color screens and in multi-color screen films and screen plates
IPC: G03C7/06
Filed: 1926-03-16
Abstract: 257,836. Thornton, J. E. March 16, 1926. Drawings to Specification. Colour photography, screens and screen plates for.-A four-colour screen, applicable, to flat or roll films or to glass plates, is built up from two partial screens comprising coloured lines, which are produced by photographic and dye processes, and are superimposed so that the lines of one partial screen cross those of the other. The partial screens are formed in colloid layers which are applied either upon separate supports which are finally cemented together face to face or back to back, or upon opposite sides of a common support. In the case of a glass plate, one partial screen is formed on the plate, and the other on a thin film cemented thereto. The sensitive layer may be applied on one side of the finished screen, and a non-curling colloid layer may, in the case of thin films, be applied on the other side. Each of the partial screens is produced by sensitizing the colloid layer as with bichromate or an iron salt, dyeing it with one of the screen colours, exposing it under a line screen to harden the parts not covered by the lines, washing to remove the dye and sensitizer from the unhardened parts, drying, and then dyeing the unhardened parts with the second colour. In a modification in which the screen is built up from three colours only, the second dyeing step is omitted in the case of one partial screen so that this comprises lines of one colour separated by colourless transparent lines. 'The colloid layer may alternatively be sensitized with silver, and, after exposure and development, be treated with an oxidizing bath to render the colloid insoluble in proportion to the content of metallic silver. The layer is freed from silver salts in known manner. Specifications 224,571 and 253,643 are referred to.

Abstract: 217,646. Levy, L. A. March 19, 1923. Thorium and alloys, depositing.-A tungsten, platinum, or other filament for use in a thermionic valve is treated in an electrolyte containing a solution of a thorium compound. The electrolyte may consist of 10 grms. of hydrated thorium chloride and 10 grms. of sodium chloride dissolved in 50 c.cms. of water and 50 c.cms. of alcohol. Tungsten wire is connected as cathode and is passed at such a rate that each part of the wire remains in the electrolyte for not more than half a minute so as to avoid the deposition of thorium oxide. The current density may be adjusted to 2 amps. per square inch by the use of an auxiliary cathode. In a modified process a small amount of a salt of nickel, copper, lead, or other metal, for instance 2 grms. of nickel per litre, may be added to the electrolyte. It is suggested that nickel is deposited either in metallic form or as a compound which occludes or assists in depositing thorium. Thorium per-. chlorate produced by saturating perchloric acid with thorium hydroxide may be used instead of thorium chloride. In another method, thorium is deposited on metals of the platinum group from an electrolyte consisting of a solution of anhydrous thorium chloride in a mixture of fused sodium and potassium chlorides.

Filed: 1967-02-21
Abstract: 1,172,281. Circuits employing bi-stable magnetic elements; transistor amplifying circuits. WESTINGHOUSE ELECTRIC CORP. 21 Feb., 1967 [16 March, 1966], No. 8113/67. Headings H3B and H3T. A sense amplifier circuit for a memory system comprises a balanced amplifier coupled to the normal mode sense output of the memory and by means of a transformer to a sense signal strobing circuit. The memory system comprises a plurality of stacks with a plurality of memory planes in each stack. The core sense winding of a memory sense circuit 14 of each plane is coupled to an individual pre-amplifier circuit 12, 12A, 12B, 12C &c. and all the amplifier circuits are coupled by transformers 18 to a common output circuit 16. Pre-amplifier 12 comprises two NPN transistors 26, 28 coupled through respective emitter followers to transformers 18 arranged to form a balanced amplifier so that in operation a normal mode sense output signal across resistor 20 causes a difference in potential of the bases of transistors 26, 28 and an amplified voltage difference across collector terminals 30, 32. This voltage difference is coupled to the transformer 18 and thence to output circuit 16. Common mode voltage changes at resistor 20 cause equal changes in the transistor base potentials and hence no voltage change is produced across transformer 18. With no induced transformer secondary voltage transistor 66 of output circuit 16 is normally held off. When the signal across the secondary winding of any of the transformers 18 exceeds the forward voltage drop across any of the threshold diodes 82, 84, transistor 66 is caused to conduct. The collector terminal of level detector transistor switch 66 is connected to the base of transistor 92 through diodes 98, 100 to provide base drive therefor when another diode 102 is back biased by a strobe pulse. When base drive current is supplied to the transistor 92 the drop in value of the collector voltage is passed to register 19 after which the sensed core is reset to its original state after the strobe pulse time and at the completion of the memory core cycle.
