Title: A process for recovering the latent heat of condensation from a mixture of at least one non-condensable gas and at least one vapour
IPC: B01D1/06
Filed: 1958-04-03
Abstract: A process for the recovery of the latent heat of condensation from a condensing mixture formed of at least one gas, which is non-condensable in the operative temperature range, and at least one vapour, which is condensable in the operative temperature range, comprises causing a recovering mixture of at least one gas which is non-condensable in the operative temperature range and at least one liquid to flow in heat-exchange relationship with the condensing mixture in the opposite direction and in separate channels to the flow of the condensing mixture, the components of the recovering mixture being such that, during a thermal exchange, the specific heat of the recovering mixture varies, due to the evaporation of a liquid component in such a way that the variation of the enthalpy of the recovering mixture with changes of the temperature is similar to the variation of the enthalpy of the condensing mixture with the same changes of temperature.  The process is especially applicable to the recovery of a mixture formed of the same substances as the condensing mixture, in which case the recovered heat is utilized to form a mixture with the same components and the same characteristics as the condensing mixture before the thermal exchange.  In a preferred embodiment the gaseous component of the recovering mixture carries the liquid component as a film along a channel wall separating the condensing mixture from the recovering mixture using the surface condensers described in Group XIII.

Title: A device for finish rolling of cylindrical surfaces
IPC: B24B39/02
Filed: 1953-04-21
Abstract: 727,362. Axial rolling; boring heads; milling. PREIS, G. April 21, 1953, No. 10956/53. Classes 83 (3) and 83 (4). Axial rolling.-In devices for rolling internal or external cylindrical surfaces, cylindrical rollers run on or within an expanding race which is adjusted to the required diameter by the engagement of an axially slidable conical member with an expanding sleeve. In one example for rolling an internal surface the rolls 1, Fig. 1, are supported in a cage 3, rotatable on a hub 2, and roll over an expanding race 4 in the form of a helical spring. A cap 9 on a bolt 8 retains the rolls 1 endwise in the cage 3. Adjustment of the effective diameter is obtained by rotation of the bolt 8 by which a conical member 7 is drawn axially into a split collet 5. A slight taper may be given to one or other of the faces of the race 4, collet 5 or cone 7 so that the rolls 4 yield slightly at the trailing end for ease in extracting the tool from a blind hole. In a modified form for rolling external cylindrical surfaces, rolls 10, Fig. 3, run within an expanding race 14 which is contracted by clamping screws 18 engaging a pair of opposed conicallyfaced rings 16, 17 surrounding a contractible ring 15 which is split or slotted. The rolls 10 are located within a cage 11 held within a hub 12 by a plate 13. Boring-heads; milling.-In a modification the bore of a cylinder is rolled to final size by rolls 25, Fig. 5, on a hub 21 carrying rotary cutters 37 which machine the bore to a required diameter before engagement by the rolls 25. Adjustment means for the rolls 25 comprises an expanding race 27 and cone 29 which is axially screwed along the hub 21 by rotating a sleeve 23 carrying a pin 35 engaging the cone 29 and locked in position by a key 34. The cutters 37 are of different diameters to rotate at different speeds, but have their outer cutting-edges on a common cylinder, and are mounted on pins 38 in a rotatably mounted cage 39. The pins 38 carry pinions 40 of different size engaging a gearwheel 42 keyed to the hub 21, and act as milling cutters. The teeth of the cutters may be helical or at a skew angle to the axis. If rotation of the cutters 37 on their own axes should be prevented by accumulation of cuttings &c. the device as a whole acts as a boring-head.

Title: Improvements in the colouring of textile and other materials
IPC: D06P3/40
Filed: 1940-06-29
Abstract: 542,180. Dyeing textiles &c. ELLIS, G. H., and WESSON, A. J. June 29,1940, No. 11042. [Classes 2 (iii) and 15 (ii)] Fibres, foils and films of cellulose esters or ethers or mixed textiles containing such fibres are coloured by forming therein a lake of a mordant dye from a solution, applied thereto as an impregnating medium, of the dye and a salt of the mordant metal in a liquid medium containing at least 25 per cent. of an organic liquid boiling below 150‹C. The latter is advantageously removed by evaporation, e.g. by a steaming treatment, prior to the formation of the lake. Specified organic liquids are methyl, ethyl, propyl and isopropyl alcohols, acetone, methyl ethyl ketone, methyl and ethyl acetates and ethyl lactate and 15-46 per cent. of water may be present in the liquid medium. Specified mordant metal salts are the chlorides, fluorides, thiocyanates, formates and acetates of chromium, aluminium and iron. Specified mordant dyes are Solochrome yellow 2GS, Solochrome flavine GS, Alizarine yellow GD, Chromosol yellow GD, Alizarine red AS, Metachrome bordeaux BL, Anthracene blue G, Omega chrome brown 3GL, Metomega chrome brown DME, Solochrome brown RHS and RGS, Omega chrome khaki GDM, Alizarine chrome green SNA, Solochrome fast grey 2GS, Solochrome black FVS and Diamond black PBB. For the production of solid shades on mixtures of cellulose ester or ether fibres with animal fibres, e.g. wool or silk, an acid such as acetic acid is incorporated in the liquid. In an example, cellulose acetate staple fibre is dyed a blue shade, fast to milling, by immersing it for 15 minutes in aqueous methylated spirit at 30- 35‹C. containing Anthracene blue G800 and "acetate of chrome," draining, centrifuging, drying first below 40‹C. and then at about 70‹C., steaming, soaping, rinsing and drying. The Provisional Specification refers also to the use of diacetone alcohol as the organic liquid and to a modification of the process wherein the dye and the mordant metal salt are applied separately to the material, at least one of them being applied in solution in the organic liquid, e.g. a solution of the dye in the liquid may be applied to filaments spun from a solution containing the mordant metal salt. ,

Abstract: 551,692. Food preparations. BRITISH ARKADY CO., Ltd., FORD, W. P., EGERTON, W. E., and MAIDEN, A. M. Aug. 29, 1941, No. 11065. [Class 49] An edible product is obtained by treating comminuted soya beans with water at 100‹C. or thereabout and with a soya protein coagulating agent between 50‹ and 100‹C. or thereabout and separating, as by filtration, the insoluble material constituting the edible product from the liquid. The coagulating agent may be an innocuous water soluble acid, e.g. hydrochloric or citric acid, an acid salt, e.g. cream of tartar, or calcium or sodium acid sulphate or an iron, calcium, magnesium, sodium, potassium or ammonium salt or a mixture of any of these. The soya flour and agent may be mixed with water and boiled or mixed and treated with boiling water; or the soya may be treated with a boiling aqueous solution of the agent; or a mixture of soya and water may be boiled and treated, if necessary after cooling, with the agent between 50‹C. and 100‹C. The pH value should be brought between 3.5 and 6 when an acid or acid salt is used and may be as high as 7.5 when a neutral salt, with or without an acid salt, is employed. The quantity of iron &c. salt. may vary from 1 per cent to 15 per cent of the soya. If the solubility of the protein has been reduced by a previous treatment of the soya, the protein should first be dissolved by treating the soya in aqueous suspension with alkali at a pH not above 11, the pH being then adjusted between 6.5 and 7. In this case, when an acid or acid salt is used as a coagulant, the pH should be between 2 and 5.5.
