Title: Improved process for the production of transfer pictures
IPC: B44C1/175
Filed: 1928-05-21
Abstract: 317,871. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 21, 1928. Transfers; transferring designs. - In transfers for applying designs, wood or marble graining, pictures, trade marks, advertisements, &c. to glass, wood, metal, or other materials, either directly or on a coating of lacquer or paint, the transferable layer coming into contact with the surface to be decorated is an adhesive layer containing cellulose derivatives, and, if desired, resins which are both soluble in alcoholic solvents. This layer may be the design layer or a transparent or opaque coloured layer which forms a background for the design when applied. Before applying the design to the transfer paper, the paper may receive a coating of a composition containing cellulose derivatives, which coating forms a protective coating for the design when applied to the surface to be decorated. The transfers are particularly suitable for application to cellulose lacquers substantially insoluble in alcohol such as those used for lacquering motor cars, and the transfer is effected by wetting the surface of the transfer with alcohol and applying by pressure. In one example, the transfer paper is printed with a design in an ink consisting of 15 parts of an alcohol-soluble nitrocellulose, 9 parts of tricresyl phosphate, 3 parts of castor oil, 7.5 parts of resin soluble in alcohol, 15.5 parts of an organic or inorganic pigment or metal powder, 10 parts of alcohol, 20 parts of ethylene glycol mono-methyl ether, and 20 parts of ethylene glycol mono-ethyl ether. In another example, the transfer paper is first provided with a coating composition consisting of 160 parts of cellulose ethyl ether, 25 parts of tricresyl phosphate, 15 parts of triphenyl phosphate, 30 parts of castor oil, 20 parts of colophony esterized with glycol, 400 parts of xylene, 200 parts of butanol, and 150 parts of ethylene glycol mono-ethyl ether. Upon this layer the design is printed in oil colour or in an ink consisting of 150 parts of nitrocellulose, 70 parts of tricresyl phosphate, 30 parts of triphenyl phosphate, 65 parts of milor blue, 35 parts of colophony esterified with glycerol, 150 parts each of xylene and of butanol, and 350 parts of acetate of ethylene glycol mono-ethyl ether. A covering layer of lacquer consisting of 200 parts of an alcohol-soluble nitrocellulose, 100 parts of dibutyl phthalate, 50 parts of colophony, 200 parts each of ethyl alcohol and ethylene glycol mono-ethyl ether, and 250 parts of acetate of ethylene glycol mono-ethyl ether is then applied. The design may be printed on the transfer partly in opaque and partly in transparent colours if desired.

Patent GB-397987-A (GB)
Title: Improvements in the manufacture and production of acetylene from gases containing hydrocarbons
IPC: C07C4/02
Filed: 1932-05-30
Abstract: In the manufacture of acetylene by the electric-arc treatment of other gaseous hydrocarbons, including dispersions of liquid or solid hydrocarbons or other carbonaceous materials in hydrogen, the gases are passed through a series of arcs after each of which the acetylene formed is removed, and in which the amount of energy supplied per unit volume of gas successively increases to such an extent that the concentration of acetylene in the arc gases is successively increased.  This may be effected by using arcs of successively increasing energy and (or) by successively reducing the speed of the gases.  The arcs may be operated at any desired pressure; for example, the first arc may be operated under reduced pressure and later arcs at higher pressures.  An example is given in which a gas containing methane, ethane, propane and butane is passed successively through arcs having powers of 1100, 1815, and 3993 kilowatts, the acetylene formed being converted catalytically into acetaldehyde and washed out with water after each arc treatment, and the concentration of acetylene in the gases from successive arcs being 10, 12, and 17 per cent; the third arc may be replaced by two arcs in parallel. Reference is made to the use of a series of 2-6 arcs, and to the treatment of waste gases from cracking and hydrogenation plants, natural gas, and dispersions of coal or coke dust in hydrogen. Specification 337,088, [Class 2 (i), Acetylene], is referred to.

Abstract: 980,659. Distilling water. SULZER BROS. Ltd. April 18, 1963 [April 18, 1962], No. 15394/63. Heading B1B. Fresh water is obtained from salt water by feeding it from tank 103 into distillation unit 82-85 wherein part of the water is distilled and the distillate (i.e. fresh water) is collected in pipe 93, and some of the salt water is fed through pipe 22 to a heater 23 and then into a flash evaporator 26, 30, 33 ; the steam from the flash chambers is conducted, via pipes which pass through superheater 37, into turbine 45, and the steam leaving the turbine is condensed to obtain additional fresh water. The salt water withdrawn from the last stage 33 of the flash evaporator is passed through pipe 34 into the first stage 85 of the distillation unit. In the apparatus shown, the distillation unit is a multiple-effect apparatus, but a vapourcompression still or a multi-stage flash evaporator may be used instead. Heater 23, superheater 37 and the first stage 85 of the multiple effect apparatus are heated by a stream of hot gas produced by gas turbine 49 and burner 53. In an alternative arrangement, the heating medium is circulated around a closed circuit and is heated by a nuclear reactor plant. Before the salt water is introduced into the first effect 85 of the distillation unit, it is preheated in recuperators 82<SP>1</SP>-85<SP>1</SP> by the vapours leaving the four effects. Steam flashed off from the distilled water in pipe 93 may be introduced into the heating-coils of the multiple-effect apparatus. The steam generated in the last effect 82 and the steam from the turbine 45 are condensed in the same condenser 120. The salt water is heated in heat-exchanger 23 in the form of a film and in the presence of pressurized inert gas, which is introduced into the top of the heat-exchanger. Means are described for maintaining the pressure in the heat-exchanger substantially constant.

Title: Improvements in and relating to the rectification of liquid mixtures
IPC: B01D3/14
Filed: 1951-06-28
Abstract: <PICT:0737453/III/1> In fractional distillation the mixture to be distilled is evaporated in a pre-evaporator by steam or other vapour at a temperature at least about 1 DEG  or 2 DEG  C. above the boiling temperature of the feed liquid but below the boiling point of the least volatile of the components of the mixture being distilled, and the vapour from the pre-evaporator is taken to an intermediate zone of a rectifying column.  The heating steam or vapour for the pre-evaporator may be the steam or vapour leaving the column, after suitable compression.  The composition of the vapour taken to the rectifying column may be varied from that of a vapour in equilibrium with the feed liquid to a composition corresponding to that of the feed liquid by varying the proportion of the liquid fed to the evaporator which is evaporated, the remainder being discharged as liquid.  As described, a methanolwater mixture is preheated at 5 by the waste heat from the coil 3 at the base of column 1 and at first is partly vaporized in evaporator 13 and partly fed directly to the column by valve 11.  The vapours pass to the column at 14 and when the composition of the vapours is the same as that of the feed liquid valve 11 is closed and the feed liquid is totally evaporated in evaporator 13.  The overhead vapours are in part removed as product, in part condensed at 8 and the condensate returned by line 9 to the column as reflux, and in part taken off, compressed at 15 and utilized to heat the feed in evaporator 13.  The condensate thus formed is returned by pump 18 to the reflux line 9 or may be sent for further treatment or storage.
