Abstract: 1,044,446. Distilling liquids. INSTYTUT CHEMII OGOLNEJ. Feb.26, 1964 [March 30, 1963], No. 8068/64. Heading B1B. The vapours of a substance distilled in a distillation column 2 are compressed by means of an injector 3 fed by compressed vapours of the same substance which may be produced in a cooling coil 4 of an oxidation apparatus 1, and the combined compressed vapours are subsequently condensed in a heating coil 5 in the base of the column 2, the heat thereby obtained being utilized by the distillation column. The substance, e.g. cyclohexane, may be firstly passed into the oxidation apparatus 1 and the raw product, after pressure reduction, led by conduit 11 to column 2 for distillation. Vapours and gases produced during oxidation are cooled in coil 12 and the liquefied distillate returned to apparatus 1. The condensate from coil 5 is part returned to top of column 2, part into cooling coil 4, and the remainder returned to the oxidation apparatus. The concentrated oxidatia produced from the reboiler vessel of the column is led off by conduit 15. The compressed vapours may alternatively be produced in a vaporizer heated externally by steam.

Title: Purification of crude anthracene
IPC: C07C7/14
Filed: 1928-03-19
Abstract: 304,179. Selden Co., (Assignees of Jaeger, A. 0.). Jan. 16, 1928, [Convention date]. Anthracene ; carbazole ; phenanthrene.- In a process for purifying crude anthracene, the crude product is subjected to a selective solvent treatment with a solvent containing a liquid compound having a furane nucleus, for example, methyl and dimethyl furanes, ester of furoic acid (pyromucic acid) and prelerably furfural or its homologuee. These bodies possess a low solubility for anthracene at low temperatures (15-20 C.) with a relatively high solubility for phenanthrene and carbazole. These solvents may be used alone or in conjunction with other methods of separation. For instance, semi-refined anthracene, obtained by previous treatment of the crude body with phenanthrene solvents, such as benzene, toluene, solvent naphtha, odichlorbenzene and other similar chlorinated compounds may be subjected to the above described purifying process. The two solvent processes may also be combined, using a mixed solvent, comprising the phenanthrene solvents mentioned above, and the furane solvents. In this case, the furane solvents preferentially dissolve the carbazole. The cake obtained after the furane solvent has been removed containing phenanthrene, carbazole and traces of anthracene, may then be further treated to separate its constituents. For example, a treatment with 98 per cent sulphuric acid at 20-25 C., with or without the addition of a solvent inert towards the acid to remove traces of anthracene present, and subsequent dilution, almost chemically pure carbazole is obtained. Alternatively the cake may be treated by fusion with caustic potash, with or without the addition of caustic soda and/or indifferent diluents such as hydrocarbons, at a temperature of 150-250 C., forming an alkali salt of carbazole. Finally, the residual cake may be subjected to vapour phase catalytic purification in the presence of catalysts which favour the combustion of carbazole, or the cake may be catalytically oxidized. Suitable catalysts consist of a composition containing cobalt, copper or ferric oxide, precipitated from the corresponding salts, stabilized by the addition of potassium hyroxide or nitrate, and coated on to pea-size pumice fragments, and then heated in air at 350-400 C., used for the selective oxidation of impurities at 380 C., or a catalyst consisting of ferric oxide and potassium nitrate, coated on to pumice fragments and used at a temperature of 380-400 C. for more or less complete oxidation. The above secondary purifying process may also be used before or after the solvent treatment with furane derivatives. Specification 291,419 is referred to.

Title: Improvements in and relating to shoe sole vulcanising machines

Abstract: 850,774. Shoe sole vulcanising machines. C. I. C. ENGINEERING Ltd. March 15, 1957 [March 20, 1956], No. 8635/56. Class 87(2). Two heated side mould members 6 and a heated sole mould member 10 co-operate to confine a sole length blank of a vulcanisable elastomer in relation to a last-supported shoe upper, the opening and closing of the mould members being effected positively and solely by fluid pressure under control primarily of an electrically-actuated valve 23 which is associated with a timing mechanism 34 brought into action by means of a manually operated switch 29 and automatically put out of action by movement of the sole mould member, the closing action of which is delayed automatically in relation to side mould closing by a fluidoperated sequence valve 24 consequent upon rise of fluid pressure when the side mould members are arrested in a position in which they confine the shoe upper. High pressure fluid is fed from feed main 101 through line104 to a pressure reducing valve 22 from which fluid at reduced pressure is supplied by line 105 to the feed inlet of a solenoid operated fourway control valve 23 to supply pressure fluid via line 106 and branches ] 07 to each of the two sets of four horizontal cylinders 3 for effecting closure of the four side mould members 6 of the machine. As these members move inwards and are arrested as they close upon the shoe upper, a sudden rise of pressure in the operating fluid occurs and is used to trip the adjustable spring loaded sequence valve 24. This opened valve then transmits pressure fluid through line 109 and branches 110 to the sole ram cylinders 13. The ascent of the rams 12 withdraws the pressure of component 16 from micro-switch 33 which takes up an alternative position in which a timing mechanism 34 is maintained in circuit. This keeps the mould closed for a predetermined period of time during which vulcanisation of the sole takes place and at the end of this period the timing mechanism 34 operates to de-energise the coil 30 of the control valve 23, allowing the bias spring 32 (not shown) to displace the valve spool 31 to the position which effects drainage of fluid from one end of each of the cylinders 3, 13, and diversion of pressure fluid to the other ends of the cylinders, the side and sole mould members thus being opened. Specification 393,761 is referred to.
