Title: The distillation of fresh water from saline or brackish water
IPC: C02F1/10
Filed: 1963-05-10
Abstract: 1,040,313. Distillation of water. FOSTER WHEELER Ltd. May 10, 1963 [May 14, 1962], No. 18721/63. Heading B1B. Fresh water is produced from saline water by spraying the saline water through nozzle 11 on to an endless belt 3 which travels continuously between a heating zone 2 and the evaporation zone 4, conducting the water-vapour evolved from the saline water through conduit 13 into condenser 14, and withdrawing the distilled water through line 16. The belt is heated in zone 2 by passing hot flue gas over it. Solid deposits are removed from the belt by brushes 38, 39. The saline water to be distilled is preheated by using it as cooling medium in the condenser. Unevaporated saline water collects in pan 19; part of this saline water is blown down through line 24, and the remainder is recirculated to nozzle 11 via line 23. The pressure in zone 4 is maintained high enough to prevent the passage of flue gas from zone 2 into zone 4 via ports 8 and 12. This can be achieved by a valve 27 which operates in response to signals from a pressure-sensitive device in communication with zone 2. Ports 8 and 12 are provided with rolling seal members which are pressed against the belt 3 by means of springs.'

Patent GB-671878-A (GB)
Title: Improvements in drying peat and similar vegetable materials
IPC: C10F5/00
Filed: 1950-07-27
Abstract: 671,878. Preparing peat. STORA KOPPARBERGS BERGSLAGS AKTIEBOLAG. July 27, 1950 [Feb. 18, 1950; May 31, 1950], No. 18848/50. Class 50. [Also in Group XIII] Water is removed from peat and similar vegetable materials, e.g. peat moss, straw, wood, lignite, firstly by exposing the material to oxygen-containing gases under pressure, whereby partial drying is effected by the heat of the reaction, and, secondly, by evaporation from the oxidized residue of the first step, the necessary heat being provided by the steam and vapours from the first step. If an excess of steam and vapours is available from the first step, it may be used for drying fresh amounts of wet material. The starting material should have a dryness of at least 25 per cent, and if it has a lower dryness it should be de-watered, e.g. by the process described in Specification 665,164. The oxidation is effected by oxygen of, for example, 90-100 per cent purity and is accompanied by vigorous mechanical stirring. A temperature of from 150‹ to 300‹ C. at a pressure of 10 to 200 atmospheres is reached. A temperature of 160-200‹ C. and a pressure of 10 to 30 atmospheres are stated to be preferable. The evolved steam and vapour from the first step may be used directly for supplying the evaporating heat in the second step, or may be passed through a heat exchanger which delivers saturated steam at about two atmospheres pressure for use in the evaporating plant. The residue from the first step loses some of its water in the form of steam when it is withdrawn from the pressure chamber and expands. The final drying may be effected by blowing the residue, through externally-heated tubes, by a fan. The non-condensable gases leaving the heat-exchanger are washed to remove CO 2 , and returned to the pressure chamber.

Title: Improvements in or relating to dough-bleaching preparations and bread-making processes utilising the same
Inventor: LEARMONTH ERIC MITCHELL
IPC: A21D2/36
Filed: 1957-06-19
Abstract: A dough-strengthening and bleaching preparation is produced by bringing an enzymatically-oxidizable fat into intimate admixture with a material rich in fat-oxidizing enzymes under such conditions that no substantial oxidation of the fat can occur. Preferably a mixture of enzymatically-oxidizable fat and a surface-active agent is creamed in an atmosphere of nitrogen with material rich in fat-oxidizing enzymes and of low-moisture content.  Enzyme-containing materials specified are: full-fat enzyme-active soya bean flour, parts, e.g. the germs, of soya beans ground without destruction of the enzyme content and extracts of dry soya material prepared by extraction with water or salt solutions; leguminous seeds, including lentils, peas and beans, groundnuts and potatoes.  Any enzymatically-oxidizable edible fat of animal or vegetable origin may be employed, such as palm kernal ground-nut, whale and soya oils or hydrogenated products of these oils; fatty mixtures of an oil rich in oxidizable unsaturated glycerides and a solid fat, e.g. a mixture of three parts refined soya oil with one part of tristearin are particularly suitable.  The fat may include fatty partial esters, lecithin and other phosphatides.  The dough-strengthening and improving preparation may be added as a paste, a floury or crumbly mixture or an aqueous dispersion, to a conventional dough formed from flour, yeast and water in a proportion of between 1/4 2% of the total dough weight; optimum results are obtained when a doughing temperature of about 85 DEG  F. is employed. In one typical example, 41 parts of a material rich in fat-oxidizing enzymes, 12 parts partially hydrogenated vegetable fat and 3 parts glyceryl monostearate were admixed under non-oxidizing conditions and 0.35 oz. of the admixture was added to dough prepared from 28 oz. of chemically untreated wheat flour, 1/2 oz. of yeast, 1/2 oz. salt and 16 oz. water; loaves baked from this dough exhibited enhanced properties relative to control loaves baked with dough containing none of the strengthening and bleaching preparation.

Abstract: 1,078,514. Cables. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 28, 1964 [May 16, 1963], No. 19524/63. Heading H1A. In a high voltage cable a resilient, conductive layer comprising a strip of cellular material (such as an expanded or foamed synthetic polymer) loaded with carbon black, metal powder or like conductive particles, is lapped on to or folded around the stranded core of the cable to prevent electrical discharge in and subsequent breakdown of the insulation due to surface irregularities in the core and stresses in the insulation. The resiliency of the layer evens out and cushions the radial stresses introduced in the insulation during the lapping of the paper or synthetic film tape comprising the insulation and makes the cable less susceptible to damage by bending. The use of a strip for the layer permits penetration of any oil or gas impregnant used. An extruded lead sheath encloses the insulation and has an external waterproof layer of serving.
