Patent GB-879264-A (GB)
Title: Preparation of 1,4-cyclohexanedimethanol
Filed: 1958-10-08
Abstract: <FORM:0879264/IV (b)/1> In the production of 1,4-cyclohexanedimethanol by the catalytic hydrogenation of a diester of 1,4-cyclohexane dicarboxylic acid in the liquid phase, wherein the hydrogenation is carried out in two reactors 14, 22 connected in series, each containing catalyst and being maintained at a controlled temperature of 100 DEG -350 DEG C., preferably 200 DEG -300 DEG C., and under a hydrogen-pressure of 50 to 500 atm., part of the partially-reduced ester discharged from the primary reactor 14 is recycled to that reactor, together with fresh diester feed, in order to prevent the formation of injurious "hot spots" in the catalyst due to the exothermic reaction.  The mixture of recycled material and fresh feed should have, per part of mixture, a heat of reduction to 1,4-cyclohexanedimethanol equivalent to not more than 0.6 parts of the diester.  Copper chromite is a suitable catalyst; and the chromite of zinc, silver or manganese may also be used.  Manganese oxide and magnesium oxide may also be used as catalyst.  Fresh diester feed is pumped through conduit 11 into conduit 12 where it mixes with recycle material, pumped from reservoir 17.  The mixture flows into reactor 14 via heat-exchanger 13.  Hydrogen is introduced into reactor 14 via conduit 15.  The output from reactor 14 flows into reservoir 17; and a portion of this output flows via conduit and heat-exchange 21 into secondary reactor 22.  Heat-exchangers 13 and 21 can serve either to remove excess heat generated in the system or to heat the feed-material to the reactors to the desired temperature. The temperature is controlled by means of the two heat exchangers, and by varying the proportion of reducible ester in the feed material to the reactors, the latter is preferably adjusted so that the temperature rise in the reactors, due to the exothermic reaction, is in the range of 10 DEG  to 35 DEG C.  The output from reactor 22 flows to gas-liquid separator 24, from which hydrogen is vented through conduit 25, while a mixture of 1,4-cyclohexanedimethanol and by-product alcohol is withdrawn through conduit 26.  The by-product alcohol is separated from the 1,4-cyclohexanedimethanol by distillation.  Another embodiment is described wherein a gas-liquid separator and a condenser are connected between the two reactors, and part of the by-product alcohol is withdrawn from the system via the condenser.

Title: Improvements relating to the printing of positive cinematograph films
IPC: G03D15/00
Filed: 1931-11-19
Abstract: 380,647. Photographic printing processes. LESSEPS, F. DE, 65, Rue de Courcelles, Paris. Nov. 19, 1931, No. 32131. Convention date, Jan. 20. Drawings to Specification. [Class 98 (ii).] In a process of printing a positive kinematograph film sensitized with bichromate from a negative film having sections of different printing value, of the kind in which there is interposed between the source of light and the negative film a band which moves with the negative film and is divided into sections having translucencies which are inversely proportional to those of the corresponding sections of the negative film in order to compensate for the differences in printing value, each section of the band is of the same length as the corresponding section of the negative film, so that the combination of band and negative film is of uniform translucency throughout its length. The different degrees of translucency may be produced by dyeing the band various shades of red, preferably throughout its mass. Reference is made to similar processes in which (1) the negative film itself is dyed to different degrees in its different sections to produce uniform printing value ; (2) a screen band comprising a positive printed from the negative film is used, and (3) single fixed screens of graded translucency are used for each section of the negative film.

Patent GB-152975-A (GB)
Title: Improvements in processes for the production of hydrogen and of mixtures of hydrogenand nitrogen
IPC: C01B3/16
Filed: 1919-12-24
Abstract: Hydrogen or mixtures of nitrogen and hydrogen are obtained by treating with steam and in the presence of a catalyst the gases from electric and blast smelting-furnaces, and subsequently eliminating the steam, carbon monoxide and carbon dioxide; hydrogen is obtained if the gases treated are those from electric smelting-furnaces or from blast furnaces fed with oxygen; in other cases, a mixture of nitrogen and hydrogen is obtained, the relative proportions of the two constituents depending on whether the furnace is blown with air or air enriched with oxygen.  The hydrogen obtained from electric furnace, &c., gases may be mixed with the poorer mixture from blast furnace gases, or with nitrogen; also, this poorer mixture may be mixed with hydrogen. The gases after reaction with steam are passed through water scrubbers to remove the excess of steam, and then treated with alkali or alkali earth substances or with water under pressure to remove carbon dioxide; traces of carbon monoxide and carbon dioxide are removed by caustic soda, copper salts, &c.  When suitably purified, the gases may be used in the hydrogenation of fats, the synthesis of ammonia, as fuel for internal combustion engines, and for welding.

Abstract: 1,174,125. Truing grinding wheels. CHURCHILL MACHINE TOOL CO. Ltd. 10 July, 1968 [14 July, 1967], No. 32561/67. Heading B3D. A method of maintaining a dressing tool 4 at a substantially constant distance from the periphery of a grinding wheel 1 comprises continuously detecting reduction of the diameter of the wheel during a grinding operation, and moving the tool towards the wheel as a result of such reduction. In apparatus for carrying out the method, the tool 4, in the form of a diamond, is movable relative to a support 3 by a worm-and-wheel device 5 driven from a motor 6. The motor is operated by a control unit 8 connected by a fluid pipe 7 to an orifice adjacent the periphery of the wheel 1. As the wheel wears, the reduction in diameter causes a pressure drop at the orifice and the unit 8 operates the motor to move the orifice and tool towards the wheel. A potentiometer 9 is mounted on the support 3 and is connected with a unit 10 controlling the speed of a motor 2 driving the grinding wheel so that the peripheral speed of the grinding wheel remains constant

Title: Foamed polymeric sheet material and process therefor
IPC: B29C48/08
Filed: 1972-07-14
Abstract: 1400494 Foamed olefine polymer or polyamide sheets SEKISUI KASEIHIN KOGYO KK 14 July 1972 [14 July 1971] 33193/72 Heading C3C [Also in Division B5] A foamed sheet of a non-rubbery olefine polymer or a linear polyamide has surfaces impervious to liquid which enclose an intermediate foamed layer composed of pores which become progresively more elongated in the direction perpendicular to the sheet as the distance from the surface increases and which at the middle of the sheet are ruptured into a plurality of transverse films. The sheet is made by extruding a mixture of foaming agent and the polymer through a slit or annular orifice into a cooled passage where the mixture is allowed to form and increase in thickness to at least 3 times its thickness as it leaves the orifice without increasing in width or internal diameter by more than 30%, removing the foamed sheet or tube from the passage so that it can undergo any further free expansion of which it is capable and slitting the tube to form a sheet. A foamed sheet having one smooth and one rough surface is formed by separating the surfaces of the above sheet by rupturing the sheet along the middle plane of the intermediate layer. The polymers foamed may be poly. ethylene, polypropylene or nylon-12. Figs. 1-4, 7 and 8 illustrate apparatus used to form the above foamed sheets wherein polymer and foaming agent is fed through extruder 1, having screw 2, via die 3 and orifice 5 to passageway 7 where the polymer is foamed in 8. In Figs. 23 and 8 passageway 8 is lined with tetrafluoroethylene resin at 81 or 76. Figs. 4 and 7 show a foamed tube being produced in passageway 8 defined by core 71, the annular orifice being formed by core 31 supported by bridging member 32 in die 3, the foamed tube being supported on core 12 secured to core 71 by shaft 13 and then cut at 14 to produce a sheet.
