Patent GB-173538-A (GB)
Title: Process for the production of reactive acid liquor, alcohols, esters and the like from gaseous hydrocarbons
IPC: C07C67/00
Filed: 1920-06-30
Abstract: A gas containing unsaturated hydrocarbons, mainly of the olefine type, and saturated hydrocarbons, is treated with sulphuric acid of sp. gr. 1.57-1.84 at temperatures such that substantial polymerization is avoided and there is produced a liquid containing alkyl sulphuric acids higher than the ethyl compound, the liquid being capable of use for the production of monohydric alcohols, esters, &c.  The maximum allowable temperature varies from 40 DEG  C. for weak acid to 10 DEG  C. for strong acid.  Acid of sp. gr. 1.8 is preferred.  With the acid there may be mixed a neutral liquid having a solvent action on the gases, for instance a hydrocarbon oil insoluble in the acid.  Petroleum oil, freed from olefines by sulphuric acid, may be used.  The reaction may take place in a closed vessel equipped with a cooling jacket or coils and with an agitator for keeping the oil mixed with the acid; or the gas passing through the liquid may serve for the same purpose.  Alternatively, the liquids and gas may pass in opposite directions through one or more towers.  The acid liquid may be separated from the oil by settling or centrifugally, and may then have a sp. gr. of 1.5-1.2.  Alcohols, mainly secondary, are obtained by dilution, removal of any oil which separates, and distillation.  In the production of esters, by adding acetic acid, calcium acetate, &c., and distilling, it is preferred to dilute with water to the amount of 1/5 -\ba1/3 of the sulphuric acid, to check carbonization, polymerization, and the regeneration of olefines.  The gas treated may be that obtained in cracking petroleum oils, and may first be compressed to 160 lb. per sq. in. to remove condensible materials.  After the absorption of the greater part of the higher olefines as described, any residual propylene &c. may be removed by a second treatment with acid of sp. gr. 1.8 at a temperature of 50 DEG  or more, whereby they are converted into waste sludge.  Ethylene may then be absorbed by stronger acid, e.g. pure acid, preferably at higher temperatures. A neutral absorbent material, such at molten paraffin wax, may also be mixed with the acid at this stage.  Ethyl alcohol and other derivatives may be obtained from the ethyl hydrogen sulphate.  Specifications 147,737 and 160,185 are referred to.

Title: Process for the electrolytic production of zinc
IPC: C25C1/16
Filed: 1938-06-16
Abstract: 515,962. Distilling mercury. I. G. FARBENINDUSTRIE AKT.-GES., and DUISBURGER KUPFERHUTTE. June 16, 1938, Nos. 17972 [Convention date, June 21, 1937], 17973, 17974, 17975, [Convention dates, Aug. 17, 1937], 17976, [Convention date, Aug. 18, 1937], and 17977 [Convention date, Sept. 7, 1937]. [Class 82 (i)] [Also in Group XXXVI] Zinc is deposited into a mercury cathode and is recovered from the resulting amalgam by distillation of the mercury. The amalgam from the electrolytic cells is cooled, e.g., by flowing into weakly acidified water and separated by ladling, centrifuging or sieving into two fractions of which a concentration of 50-60 per cent. zinc may be obtained, the remainder of the mercury being driven off in the final stage, in .which a temperature at or near the boiling point of zinc is maintained. In the earlier stages the distillation may be effected under reduced pressure in apparatus protected by enamel; for concentration up to a zinc content of 10 per cent. the apparatus may be of weldable iron, cast iron or siliceous cast iron without a protective layer. Heating may be effected externally by mercury vapour obtained from a boiler or as waste vapour from a mercury turbine. The final distillation may be effected in x vessel of ceramic material or of graphite mouldings without reduction of pressure ; the pure zinc may be withdrawn by an overflow syphon. Heating may be effected by high frequency current. Condensation of the mercury vapour is effected in heat exchangers located above the electrolytic cells to which the mercury is to be returned ; the heat liberated may be used for the production of steam. Condensation of mercury vapour in the final stage may be effected by an injection spray condenser fed with the initial amalgam.

Title: Improvements in the manufacture of hollow tubular metal members
IPC: B21C37/12
Filed: 1936-06-30
Abstract: 477,526. Making helical tubes. McMINN, W. W. June 30, 1936, No. 18132. Convention date, July 5, 1935. [Classes 83 (ii) and 83 (iv)] Coiling ; soldering.-In making cylindrical or tapered helical metal tubes, particularly for golf club shafts, a metal strip is helically coiled to form the tube which advances axially and rotates from the place of winding, and a number of convolutions are simultaneously heated by passing the blank through a high temperature heating zone and the seam united solely by bonding metal of lower melting point than that of the strip. The tubes may be finally cut off into lengths. The seam may be of the butt or bevelled overlap type. The strip, preferably of steel, may be fed by rolls 12 against dies 14 to coil it into a tube which rotates and moves axially through an electric induction furnace 20. Reducing gas, such as hydrogen, may be fed to the interior of the tube by a pipe 26 and to the exterior of the tube by a pipe 28. A brazing wire 30, having a copper base, may be fed by rolls 32 and on melting is drawn into the seam by capillary attraction. Flux may also be supplied. If excess of solder is fed, the tube may also be coated internally or internally and externally therewith. To obtain a sealed externally coated tube, the solder is fed to the exterior of the tube. An induction furnace may be used in combination with a resistance furnace to effect the brazing. After passing through the furnace 20 the tube may be quenched by oil, water or air projected from a perforated coil 36 and may then be passed through an electric resistance furnace 44 for tempering purposes. In order to keep the edges of the tube in close contact, one or more rollers 46 driven at the same or greater peripheral speed than the rotation of the tube may be used. The tube is supported by rollers 48<1> after passing through the furnace 44. In making lap-jointed tubes, the strip may be passed from the feed rolls through a second pair of rolls to form an offset flange on one edge. The brazing wire may pass under the strip through a groove 62 in one of the guide jaws and be fed by the strip or assisted by a driven knurled roller 66. The brazing wire is thus coiled in the interior of the tube.

Title: The production of a leucocytosis factor
IPC: A61K35/407
Filed: 1956-06-14
Abstract: A process for extracting a leucocytosis factor from aqueous liver extracts comprises adjusting the aqueous extract to pH5 to 10 with alkali, forming a precipitate containing the active factor by the addition of barium, calcium or lead acetate and alcohol, separating this precipitate and dissolving in water, thereafter treating the solution with an acid ion-exchanger whereby metals and impurities are absorbed, the solution containing the active factor is then treated with a basic ion-exchanger, which is then eluted with an alkaline solution to liberate the absorbed factor and evaporating and drying the eluate to produce an active factor in concentrated form.  As a modification of the process, the precipitate formed by alcohol and acetate may be treated with dilute sulphuric acid to remove the metal ions by the formation of insoluble sulphates which are removed and the solution then treated with the basic ion-exchanger as described above.  The active factor may be further purified by electrophoresis in which the factor is dissolved in water, an alkaline buffer added and the active factor migrates towards the anode.  The active substance which is obtained by freeze-drying the eluate from the basic ion-exchanger is yellowish-brown, a 1 per cent solution of which gives an extinction E1 per cent 1 cm.=30 at a wavelength of 260 millimicrons.  The factor was found to contain 1 per cent phosphorus and has an acid reaction.
