Patent GB-303504-A (GB)
IPC: F25B15/10
Filed: 1928-12-11
Abstract: 303,504. Siemens - Schuckertwerke Akt.-Ges. Jan. 5, 1928, [Convention date]. Refrigerating, absorption machines and processes for.-Unevaporated refrigerant or solution collected in the evaporator of condensing systems is heated by external means on its return to the generator side of the system. As shown in Fig. 1 as applied to a condensing system with a light inert gas circulating between the evaporator 21 and the absorber 23, liquid from the evaporator is led through a pipe 33 to a vessel 34 heated by an electric heating element 35, whereby refrigerant vapour is driven off and passes, together with any liquid, into the gas space of the rectifier-separator vessel 29. Liquor and gas are passed from the main generator 26 into the vessel 29, whence the gas flows on to the condenser 32 and the evaporator while the weak liquor flows to the absorber by way of a pipe 30 interchanging heat with the strong liquor pipe 25. The inert gas pipe 24 from the absorber rises above the evaporator. In a non-condensing system shown in Fig. 2, and comprising a main heated generator 56, separator 59, rectifier 52, absorber 48, reabsorber 66, and cold-producing generator 41, with an injector nozzle 73 in the inert gas circuit 46, 47, 44, excess liquor flows from the coldproducing generator through a pipe 62 to a vessel 64, whence the greater part is led to the reabsorber by a pipe 65, while the rest is passed through a pipe 74 to a vessel 75, which is heated by an element 76. The evolution of gas here serves to lift the liquid into the absorber, or, as in a modification of this system, to the top of the rectifier.

Title: Improvements in or relating to multi-channel electric wave signalling systems
Inventor: ASPINWALL JOHN FRANCIS HERBERT
IPC: H04B1/68
Filed: 1960-10-26
Abstract: 913,089. Multiplex systems. COMMUNICATIONS PATENTS Ltd. Oct. 26, 1960, No. 36746/60. Class 40 (4). In a multiplex transmission system each signal band is transposed to a higher frequency channel by using two pairs of balanced modulators, each higher frequency channel being adjacent to the next so as to form a single multi-channel signal. A known form of frequency changer (Fig. 1) is employed in which a signal source 12 (300-3000 c.p.s.) supplies two balanced modulators 10, 11 fed respectively with oscillations in quadrature from an oscillator 15 (1650 c.p.s.), the modulation products in the range 0-1350 c.p.s. being fed via lowpass filters 18 and 19 to further balanced modulators 16 and 17. The latter are fed with oscillations in quadrature from an oscillator 22 (about 450 kc/s.), the outputs of 16, 17 then being combined at 23 to form the upper side-band of a 450 kc/s. carrier. By adjusting network 20, say, to be in phase opposition to network 13 then a lower side-band signal can be obtained as is explained mathematically in the text. Fig. 2 shows part of a transmission system using the above modulation process wherein modulators 40 and 41 supply the upper sideband and modulators 42, 43 supply the lower side-band of a suppressed carrier (465 kc/s.) multi-channel signal. Amplifiers 48-51 have substantially constant output impedances so as to prevent intermodulation products on the line " 52 " arising from varying signal amplitudes in each channel. A suitable demodulation arrangement is also described with reference to Fig. 4 (not shown).

Title: A method for improving the textile processing of fibres and threads made from synthetic, linear, aromatic polyesters
IPC: D06M11/71
Filed: 1957-11-29
Abstract: The textile processing of artificial fibres and threads made from synthetic linear aromatic polyesters is improved by treating them with an aqueous solution of at least one alkali metal hydroxide and at least one compound with a surface-active anion. Suitable compounds with a surface-active anion are the sodium and potassium salts of fatty acids, alkyl aryl sulphonates, fatty alcohol sulphates and sulphated fatty acid salts of di-ethanolamine.  The treatment may be effected either in the cold or at a raised temperature, but in the case of dilute solutions containing not more than 1% by weight of alkali metal hydroxide and not more than 1% by weight of the compound with the surface active anion, a raised temperature, e.g. of at least 60 DEG C., is preferably used.  The materials are preferably stirred during treatment, or the solution may be pressed through the materials. After treatment, the fibres or threads may be rinsed with water prior to drying.  If, in the course of textile processing, the fibres or threads are subjected to a heat treatment, e.g. steam treatment, to produce stabilization, the alkaline treatment is preferably carried out after the heat treatment.
Patent GB-949193-A (GB)
Title: Production of organic compounds containing carbon-to-carbon double bonds in terminalpositions only
IPC: C07F5/06
Filed: 1960-10-31
Abstract: An unsaturated organo-aluminium compound is converted to a saturated organo-aluminium compound by reaction with hydrogen in the presence of a hydrogenation catalyst at a temperature of from 0 DEG  to 150 DEG C.  The catalyst may be a Group VIII metal, and the hydrogenation may be carried out in the presence of an inert diluent e.g., pentane or heptane.  The process is particularly useful in removing internal unsaturation from a compound containing both internal and terminal unsaturation (e.g. vinyl cyclohexane from vinyl cyclohex-4-ene) or in separating a compound containing terminal unsaturation from its mixture with a compound containing non-terminal unsaturation.  The said compound or mixture of compounds is converted to a trialkyl aluminium compound by displacement with a compound such as tri-isobutyl aluminium or by an addition reaction with an aluminium hydride, both reactions taking place at the terminal double bond. The so formed organo-aluminium compound is hydrogenated, thereby removing internal unsaturation or converting the compound containing nonterminal unsaturation in the mixture into a saturated compound. The organic compound containing terminal unsaturation only may then be recovered by displacement with a primary olefin or by thermal dissociation of the organo-aluminium compound.ALSO:Vinyl cyclohexane may be prepared from vinyl cyclohexene (e.g 1-vinyl cyclohex-4-ene) by reacting it with tri-isobutyl aluminium to produce a b -cyclohexenylethyl aluminium compound which may be catalytically hydrogenated and the hydrogenated product may then be reacted with an olefin such as 1-dodene in a displacement reaction giving vinyl cyclohexane. The process is generally applicable to the elimination of internal saturation from olefines containing both terminal unsaturation and non-conjugated internal unsaturation.

Abstract: 344,499. Photo-electric cells. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hull, A. W. ; 1021, Waverly Place, Schenectady, New York, U.S.A.) Dec. 5, 1929, No. 37318. Convention date, Dec. 27, 1928. [Class 39 (i).] A photo-electric cell is pro. vided with a cathode consisting of plane surfaces coated with a light-sensitive substance and disposed at such an angle relatively to one another that the maximum photo-electric effect is produced by a beam of light which makes equal angles of incidence with each of the cathode surfaces, an anode being disposed symmetrically with respect to the surfaces. The example shows a photo-electric tube 1 containing a cathode consisting of two abutting metallic plates 4 coated with alkali metal and disposed at an angle of approximately 140‹ to one another, with an anode 5 in the form of a vertical wire or rod arranged equidistantly between them. A capsule 7 at the top of the anode contains a compound, for example caesium dichromate and silicon, which evolves alkali vapour when heated. The sensitivity is increased by providing a smooth or specular light-sensitive cathode surface, such as silver-plated copper. The electrodes are mounted upon a stem 2, and the tube is exhausted and heated, after which a small amount of oxygen may be admitted when the tube has cooled. The oxidation process is preferably effected by a glow discharge between the anode and cathode, the free oxygen subsequently being pumped out and the capsule 7 flashed to release the caesium, which condenses on the silver oxide to form the lightsensitive surface. The cathode may be in the form of a cone with a smooth light-sensitive surface converging at the necessary angle towards the apex.
