Filed: 1940-04-19
Abstract: 543,604. Soap and soap compositions; glycerine. DU PONT DE NEMOURS & CO., E. I. April 19, 1940, No. 7109. Convention date, April 19, 1939. [Class 91] [Also in'Group IV] Fatty glycerides are re-acted with 0.1-0.5 per cent. of alkali and 1.2-1.75 equivalents of a monohydric alcohol of 1-5 carbon atoms, and the alkyl esters, after separation from the glycerine and after fractional distillation, if desired, to remove the lower-boiling esters, are saponified with caustic soda or potash, which may be in methyl or other alcoholic solution or may be finely-ground and used with little or no alcohol, or may be a 50 per cent. aqueous solution. The mixed alkyl esters of unsaturated acids, e.g. from cotton-seed oil, may be hydrogenated before saponification so as to form palmitate and stearate soaps. Examples describe the treatment of coconut oil, and in one case cotton-seed oil ; in the latter case the soap is mixed with titanium white and glycerol monostearate and monooleate. Other oils mentioned as suitable initial materials are olive, palm, sardine, castor, whale and linseed oils, tallow, stearin and cocoa butter. Specification 125,153, [Class 91], is referred to.

Title: Process and apparatus for the preparation of improved cereal flours
IPC: A23L7/104
Filed: 1961-02-27
Abstract: 957,839. Treating cereal grains. J-P. LEPETRE. Feb. 27, 1961 [March 1, 1960], No. 7114/61. Heading A2Q. A flour of 40% greater digestive quality than that of conventional flour and in which the starch has a substantially unbranched structure, is prepared by subjecting cereal grains to enzymatic autolysis in an aqueous acidic solution at a temperature of 15‹ to 65‹C., a pH of 4.2 to 6.8, an oxidation-reduction potential of 250 to 450, a resistivity of 115 to 180 ohms per centimetre, and an oxygen content of 2 to 6 cc. per litre of solution, and then high pressure milling the autolysed grains at an elevated temperature whereby they are substantially dried and ground to flour. Under preferred operating conditions the grains are washed in a solution acidified to pH 6.2-6.5 and given a preliminary digestion under specified conditions for up to five hours, the solution in which the enzymatic autolysis of the grains takes place is acidified initially to a pH of 4.6 with orthophosphoric acid and the grains are stirred in the solution for from 1 to 10 hours until the pH of the solution reaches the iso-electric point of the proteins of the grains, thereafter the solution is restored to a pH of about 5.6 by addition of a specified phosphoric acid, permitting the appearance in the solution of appreciable quantities of α and # amylases, and the mixture is allowed to stand for from 1 to 4 hours prior to being milled between cylinders to about 150‹C. Cereals mentioned are wheat, barley, maize, rice and rye. The grain, after washing and preliminary digestion in a column 1 during which light and heavy impurities are removed by manipulation of screens 7 and 8, respectively, passes to the autolysis column 2 provided with a thermostatically-controlled jacket 12 and probes 18, 19, for the control of the oxygen content of the liquor and of its pH, oxidation-reduction potential and resistivity, and is subsequently drained on a plate 22, dried to flour on heated rollers 30 and further dried during its passage down the conduit 33 by warm air fed through a duct 34; the dried grain may finally be treated by blade or hammer pulverisers (not shown). The autolysis liquor used in the column 2 is prepared in the auxiliary column 2a from the waste bran and middlings obtained from flour milling and drainage liquor from the column 2 collected into the three tanks 25, 26 and 27 according to its pH; the same reactions take place in the auxiliary column as in column 2, but they are allowed to go to completion until the enzymes have no further action. Parts of the apparatus in direct contact with the grains are covered with a ceramic or plastics material.

Abstract: 1520232 Testing digital links LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 21 Feb 1977 [27 Feb 1976] 7251/77 Heading H4P In the checking of a digital link including a telephone line, check messages are transmitted alternately from each end of the link, each check message comprising an n fold repeated, i bit synchronization character followed by a p bit pseudorandom sequence, itself followed by an i bit quality character representing the coded quality of the last received check message. Upon receipt of a check message at one end, a quality character is derived by counting the number of correctly received sync. characters and coding the result, and by comparing the received pseudorandom sequence with a locally generated sequence, and coding the number of errors. The coded results together constitute the quality character, which is displayed, and transmitted at the end of the next transmitted check message. The received quality character is stored and displayed, so that the quality characters for both directions of transmission are displayed at each end of the link. Apparatus for performing the operations is disclosed in relation to Fig. 3 (not shown). The message timing is discussed in relation to Fig. 4 (not shown). The synchronisation characters are used to synchronise the apparatus at the ends of the link.

Abstract: Permeable structures of concrete, mortar, and the like are rendered less permeable, and are strengthened, by applying separately, e.g. by pressure, lime water and carbon dioxide either alone, mixed with other gases, e.g. air, or in aqueous solution. To ensure that insoluble crystalline calcium carbonate is formed by the reaction of the calcium hydrate and the carbon dioxide, the p  temperature should not be allowed to rise to 60 DEG  C. and the carbon dioxide should not be supplied in excess.  The lime water may also contain, in suspension, solid filling material, e.g. calcium carbonate, finely crushed brick or other puzzolanic material.
