Title: Solid antifoam crystals for dry beverage mixes
IPC: A23L2/40
Filed: 1976-04-20
Abstract: 1535958 Solid anti-foam crystals for dry beverage mixes PROCTER & GAMBLE CO 20 April 1976 [21 April 1975 12 Dec 1975] 15926/76 Heading C6E A rapidly dissolvable and substantially dry antifoam additive for dry beverage compositions comprises a uniform crystalline matrix of crystalline sugar, flavourant and silicone anti-foam agent. The anti-foam additive is prepared by a method broadly involving uniformly dispersing the silicone antifoam agent in a liquid flavourant using water to make a homogeneous solution, mixing the solution with a crystalline sugar to form a uniform slurry, and dehydrating the slurry as by vacuum drying or freeze-drying in such a manner as to form a stable foam of final moisture content 3% or less. The dried crystalline material is then ground. The silicone anti-foam agent comprises 0.1 -3% and the flavourant 0.2-10 wt. per cent of the anti-foam additive. The anti-foam additive may be introduced into a dry beverage mix, typically in amounts ranging from 0.25 to 6wt. per cent of the total. Several examples disclose the preparation of antifoam additives containing sucrose, cola-base flavouring and commercially available methyl silicone anti-foaming agent (30% silicone in water). In one case the solid anti-foam crystals contained 1714 ppm of methyl silicone. The crystals (60 mg) were mixed with dry beverage crystals (6 g) and the resulting mix was added to a 12 oz. cup containing a molecular sieve carbonation device. Water and ice were added to fill the cup. The amount of silicone, by weight of the beverage including ice, was 0.3 ppm.

Title: Improvements in or relating to a gas turbine plant
IPC: F02C6/14
Filed: 1954-05-28
Abstract: 753,930. Gas turbine plant. SIEMENSSCHUCKERTWERKE AKT.-GES. May 28, 1954 [May 29, 1953], No. 15947/54. Class 110(3) [Also in Groups XII and XIII] In a gas turbine plant, compressed air flows continuously through a regenerator to the turbine or turbines, the regenerator being intermittently charged by the combustion of fuel introduced into the air. In the gas turbine plant shown, air is supplie by a compressor 1 by way of a preheater 2 to a combustion chamber 3, from which the working fluid passes by way of a regenerator 4 and a further combustion chamber 5 to a turbine 6. Fuel from a pump 12 is admitted to the combustion chambers 3 and 5 through valves 9 and 11 respectively, the valves being controlled by a speed governor 10. Valve 11 is also controlled by a temperature-responsive element (not shown) at 8. The admission of fuel takes place intermittently and causes the regenerator 4 to be heated up. When the fuel supply is cut off, the regenerator 4 gives up heat to the air flowing through it. A mixing chamber may be provided at the outlet side of the regenerator 4, for mixing cold air with the hot gas, the admission of the cold air being controlled automatically in the same way as the fuel supply to the combustion chamber 5. Combustion chamber 3 may be separate from the regenerator 4 instead .of being combined with it. The regenerator may be arranged to remove impurities from the gas, in which case two regenerators may be provided, one being cleaned while the other is in operation. Regulation may be effected by connecting and disconnecting part of the regenerator or by the use of bleeding points in the regenerator. The temperature at the regenerator outlet may be rendered uniform by dividing the regenerator into zones of different length, cross-section or filling materials: Alternatively, the regenerator may be heated intermittently in phasedisplaced fashion by a number of parallelconnected combustion chambers which are operated with staggered periods, temperature equalization being effected, it may be by the provision of a mesh of good thermal conductivity ahead of the turbine.

Abstract: 1299666 Carbon dioxide ENGELHARD MINERALS & CHEMICALS CORP 3 April 1970 [4 April 1969] 16031/70 Heading C1A [Also in Division B1] Carbon monoxide is removed from a feed containing 0À01 to 3% vol. carbon monoxide, 50 to 99% vol. hydrogen, 0 to 5% vol. carbon dioxide and the remainder, if any, inert gas by oxidation of the carbon monoxide to carbon dioxide over a supported platinum group metal catalyst. Oxygen is mixed with the feed gas to give an O 2  : CO ratio of 0À5 : 1 to 3 : 1 and conditions used are an inlet temperature of 20-100‹ C. and a pressure of atmosphere to 500 p.s.i.g. In the Figure, a scheme is shown for producing a gas of low carbon monoxide content from a mixture of steam, air and natural gas which is fed in at line 1. The mixture is heated in furnace 2, heat exchanged in exchanger 4 then saturated with water vapour in vessel 6. The saturated gases pass by way of heat exchanger 4 to shift converter 8 in which CO is reacted with water vapour to produce CO 2  and H 2 . The effluent gases are cooled by water in tower 10 and then passed through monoethanolamine absorber 12 to remove carbon dioxide. The mixture at this stage typically comprises 0À1% CO 2 , 0À5% CO; 0À4% methane and 0À3% argon. The mixture is finally passed over the supported platinum metal catalyst in vessel 16 to remove the last traces of carbon monoxide, and then through CO 2  absorber 20 and gas cooler 22 to use, e.g. in ammonia synthesis. Lines 24 and 26 are provided so that the flow of the gas mixture over the catalyst may be reversed when the catalyst becomes deactivated so as to regenerate it without interrupting flow.
