Patent GB-1560209-A (GB)
Title: Sterilizing of milk and foodstuffs
IPC: A23C9/12
Filed: 1978-05-31
Abstract: Liquid food products, particularly milk, are sterilised by a cold treatment in which oxygenated water is the sterilising agent, which is then removed completely by passing a stream of the products through a mass of fibres in which the enzyme catalase is incorporated. The process can also be carried out by bringing the fibres into contact with the products treated with oxygenated water and removing the fibres by filtration when the reaction is completed. In both cases the organoleptic properties of the food products, particularly of milk, remain unchanged.

Title: Process of producing modified filler materials and products obtained thereby
IPC: D21H17/56
Filed: 1961-07-11
Abstract: Calcium carbonate and other water-insoluble metal carbonates are treated with an aqueous polyalkylene imine solution to yield improved fillers.  The treatment may be carried out by adding the imino compound to either, an aqueous solution of the metal salt and then precipitating by the addition of an alkali metal or ammonium carbonate solution, or to an aqueous suspension of the stirred carbonate. An alternative treatment comprises adding the monomeric imine to a suspension of the carbonate and polymerizing the imine on the surface of the carbonate in known manner.  The imino compound may be polyethylene imine having a degree of polymerization between 200 and 1500, the amount used being between 0.05% and 1% by weight based on the carbonate.  All examples refer to calcium carbonate modified with polyethylene imine. Magnesium and barium carbonate are also specified.ALSO:An improved filler for paper comprises calcium carbonate or other water insoluble metal carbonates which have been surface treated with a polyalkylene imine e.g. polyethylene imine (see Division C1).  An example describes the addition of a paper pulp of 50% Hardwood Soda Pulp and 50% Softwood Bleached Sulphite Pulp which had been beaten to a freeness of 30 DEG S.R. being added to a suspension of the above treated carbonate.  Paper sheets made from resulting pulp contained 13.41% of calcium carbonate which corresponds to a retention of 51.8%.

Filed: 1929-08-17
Abstract: 338,534. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 17, 1929. Caoutchouc, synthetic.-The polymerization of diolefines is effected in presence of alkali or alkaline earth metals or their alloys in particles of uniform size, that is to say, the average diameters of the various particles do not differ by more than 10 per cent. The particles may be made by sieving the mixed particles produced by comminuting the metal in liquids or by extending the metal as wire which is mechanically cut into uniform pieces. The polymerization may be effected in presence of solvents or diluents or substances which favourably influence the reaction such as dioxane, vinyl ethers and acetals, and the temperature may be between 0‹ C. and 90‹ C. In examples (1) butadiene with the addition of dioxane is polymerized in presence of balls of sodium of 1.1 mm. diameter at 40‹ C. in an iron autoclave maintained in rolling motion; (2) butadiene with an addition of vinyl, ethyl ethers is polymerized in presence of the balls of sodium in a stirring autoclave; (3) butadiene with an addition of vinyl ethyl ether is polymerized in presence of sodium in pieces of 0.35 mm. diameter in a rotating autoclave.

Abstract: 1,036,751. Magnetic tape playback apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 25, 1964 [June 25, 1963], No. 25216/63. Heading G5R. Magnetic tape apparatus adapted for repeated playback of a short part of the tape, is provided with a store between the playback head and a take-up reel and with means for moving tape from the store to the upstream side of the head so that this part of the tape may be played back again. In Fig. 1 the tape passes through a loop 23 round pulley 1 between the supply reel 24 and the playback head 25, and through a loop 19 round a pulley 2 between the head and the take-up reel 20. The pulleys 1 and 2 are mounted on a carriage 3 which is slidable along a slipway 4 and is normally locked by a brake means 40. When repetition of a passage is desired the head 25 is muted; the reels 20 and 24 are braked; the pinch roller 22 is disengaged from the capstan 21; a solenoid 65 is energized to release the brake means 40 and allow the carriage 3 to be driven to the right by a weight 54 attached to a cord attached to the carriage, and the movement of the carriage transfers tape from the loop 19 back to loop 23; the initial movement of the carriage releases a microswitch 34 which initiates a delay, at the end of which the capstan is re-engaged; and after a further delay to allow the acceleration of the carriage and the tape, the head 25 is re-connected to resume playing. Movement of the carriage is limited by end stops each of which is manually adjustable by depressing its cap 30 and sliding it; the left end stop includes the microswitch 34 actuated by the carriage. Switch means may be provided whereby actuation of switch 34 either indicates a further repetition or allows the resumption of normal playback. In a modification, Figs. 6-14 (not showh), the mechanical end stops are replaced by adjustable members carrying switches actuated by the passage of the carriage; this arrangement is suitable for use with a cathode ray oscillograph if it is desired to display the recorded signals. The apparatus is suitable for use in teaching languages, when a word or syllable may be repeated any number of times.

Title: Improvements in and relating to the separation of the constituent phases of disperse systems
IPC: C10G33/06
Filed: 1930-08-27
Abstract: <PICT:0356926/III/1> Disperse systems in which the dispersion medium is a liquid and the dispersed phase is a liquid or gas are separated into their constituents by treatment with violet or ultra-violet light, X-rays, cathode rays, canal rays, or radiation from radioactive substances.  The dispersion preferably flows in a thin film past the source of radiation, which may be intensified by the use of reflectors, and the constituents are subsequently separated by gravitation.  The Figure shows an apparatus suitable for the treatment of a petroleum-water emulsion, which is fed by a pipe 3 on to an inclined surface 2 where it is subjected to ultra-violet light from the lamp 6 backed by reflectors 8.  The liquid may be recirculated by the pipe 11 until the emulsion is sufficiently broken to permit of gravitational separation in the settling tank 15.  The invention is also applicable to the destruction of foam, and the formation of foam during chemical processes may be prevented by subjecting the reacting substances to irradiation.
