Title: Process for the esterification of dicarboxylic acids of high boiling and decomposition point with mono- or polyhydric alcohols
IPC: C07C69/76
Filed: 1953-04-20
Abstract: Esters of dicarboxylic acids of high boiling and decomposition point with monohydric or polyhydric alcohols in which the acid is substantially insoluble, are made by treating the acid in the form of solid pieces at 100-310 DEG  C. with the alcohol in vapour form, the temperature being such that the ester is formed as a vapour which is removed from the reaction zone.  A non-volatile esterification catalyst may be present, such as phosphoric acid, phosphoric acid-carbon, zinc chloride or boron phosphate.  The alcohol vapour is suitably preheated to the desired reaction temperature before being introduced into the reaction zone. Corresponding ethers which may be formed as by-products are recovered from the reaction product and are returned to the reaction zone as esterification agents.  In examples the above method is used to prepare (1) terephthalic acid dimethyl ester; (2) terephthalic acid diglycol ester; and (3) terephthalic acid diethyl ester.

Title: Method and system for measuring and correcting vibrations generated in vehicular tyres
IPC: B24B5/36
Filed: 1977-03-15
Abstract: 1531967 Correcting false variations in tyres ONGARO DYNAMICS Ltd 15 March 1977 10863/77 Heading B7C [Also in Division B3] A method of correcting a rubber tyre for vibration producing forces generated in the tyre when operated under load and at cruising speed comprises revolving the tyre at a cruising speed equal to from 50 to 90 m.p.h. under a load simulating the weight load in normal use, measuring the magnitudes and locations of centrifugally generated forces developed in the tyre and comprising (a) forces generated by peripheral non-uniformities and (b) forces developed by lack of tyre symmetry, and correcting the tyre in two stages, the first comprising correction for the (a) forces by removing rubber from the periphery of the tyre in accordance with the magnitude and location of non-uniformities while the tyre is rotating at cruising speed, and the second comprising correction for the (b) forces by selectively adding to or removing rubber from the tyre in the area at or adjacent the tyre beads. In apparatus for carrying out the method, the tyre 17 is mounted on a test wheel and engaged by a road-simulating drum 23 which is urged against the tyre by hydraulic or pneumatic jacks 24, 25 and driven by a drive 21 at the cruising speed. Sensors 26, 27 between the jacks and bearings for the drum detect the forces (a) generated by peripheral non-uniformities, the output from the sensors being fed to a computer 28 which is connected to a controller 30 and drive 31 for a honing device 29 which removes material from the tyre at precise locations to remove the forces generated by the peripheral non-uniformities. At the same time, sensors 34, 35 acting on the bearings for the wheel sense the forces (b) caused by lack of symmetry in the tyre, the output from the sensors being fed to the computer where the signals are recorded and stored. After correction of the tyre for the (a) forces, the tyre is marked and removed from the wheel 16 and is then mounted in the same relative position in a cradle 40 which is oscillated as material is removed from ribs 36, 37 adjacent the beads 38, 39 of the tyre by a honing device 41, 42 controlled by a controller according to the stored signals in the computer whereby the forces (b) caused by lack of tyre symmetry are corrected. Alternatively, strips of rubber may be added to the ribs to correct for the (b) forces.

Abstract: 101,152. Rasmussen, C. O. Aug. 8, 1915, [Convention date]. Gaseous mixtures: materials for making gas.- In the production of illuminating, heating, and like gas from peat, lignite, or wood, the gas is produced in the usual manner in closed retorts and is then passed through one or more retorts filled with incandescent carbonaceous material, such as the residue cinder or charcoal from coal, peat, lignite, wood, &c., from which a part or the whole of the gas has been derived. This action, for converting the carbon dioxide in the gas into carbon monoxide, is promoted by the addition of water vapour, with a consequent production of hydrogen also. Or, instead' of using water vapour, hydrocarbons, such as masut, petroleum, coal-tar, lignite, peat, wood, &c., in fluid or pulverulent form, may be supplied to the retorts in which the decomposition takes place. The water vapour or hydrocarbons may be supplied to all or some of the retorts where the gas is produced. The gas may be produced in some of the retorts of an ordinary gasworks, and may be mixed with the ordinary coal-gas, &c.

Title: Method refining sugar juices with lime and carbon dioxide
IPC: C13B20/06
Filed: 1966-03-14
Abstract: <PICT:1106276/C6-C7/1> The method of refining raw sugar juice, e.g. raw beet juice, according to the invention comprises: initial defecation-carbonation with simultaneous addition of some of the total required quantity of lime and carbon dioxide in a low alkaline pH range between 8 and 10, and subsequent defecation and carbonation or defecation-carbonation wherein, in order to prevent local over-alkalinization in the initial defecation-carbonation stage, lime is added to the juice downstream of the initial defecation-carbonation stage in a mixing stage, in which the pH of the limed juice does not exceed 11 and the flocculated colloids are enveloped in calcium carbonate, and, depending on the quantity and nature of the impurities which are to be separated from the raw juice, corresponding proportions of said limed juice are returned to the initial defecation-carbonation stage.  As shown in the drawing, raw juice, substantially at pH 6, is passed from a container 1, through a pipe 2, into an initial defecation-carbonation zone 3 and thence, through a pipe 5, into a reaction and mixing vessel 6, where sufficient milk of lime is added, through a pipe 7, to bring the pH of the juice to a value not substantially exceeding 11.  Some of this juice is returned, through a pipe 8, to the zone 3, where sufficient carbon dioxide is introduced simultaneously, through a pipe 4, to bring the pH of the resulting carbonated juice substantially between 8.5 and 9.5.  Juice remaining in the vessel 6 flows, through a pipe 9, into a defecation zone 10, where sufficient lime is added to bring its pH to a value not exceeding 12.  The juice then flows, through a pipe 12, into a carbonation zone 13, where carbon dioxide is added, through a pipe 14, to bring the pH substantially between 10.6 and 11. The resulting cloudy juice is then passed, through a pipe 15, to a scum-separating zone 16, from which clarified juice passes, through a pipe 17, into another carbonation zone (not shown), and concentrated scum passes, through pipes 18 and 19, to be filtered.  Some of the cloudy juice may be returned, from pipe 15 through a pipe 21, to zone 3 and/or container 1.  Some of the concentrated scum may be returned, from pipe 18 through pipe 20, to zone 3 and/or container 1.
