Title: Improvements in or relating to the removal of volatile impurities from alcohol by extractive distillation
IPC: C07C29/74
Filed: 1953-09-15
Abstract: <PICT:0758095/III/1> Alcoholic liquids containing impurities such as acetaldehyde, acetone and ethyl acetate are purified, prior to rectification, by subjecting the alcoholic liquid to partial evaporation in a fractionating column maintained under vacuum, and introducing a stream of warm water into the head of the column.  This treatment eliminates acetaldehyde and acetone which, under the given conditions, behave as perfect gases and are expelled very rapidly overhead, leaving the system through vacuum pump.  Ethyl acetate also passes overhead, and is condensed.  The bottoms from the purification column are then subjected to normal rectification during which the slight traces of residual impurities are withdrawn.  Low wines from vat A pass through pipe 21 into container B which also receives, through pipe 18, the drainage water from the heating coil of rectifying column M, or through pipe 22 part of the residual boiling water from the sump of column M.  The phlegm is thus heated and diluted to about 25 DEG G.L. before entering purification column C, which is evacuated by liquidring pump D via condensers E and F. Residual water from the rectifying column M is introduced through pipe D into the top of column C, so as to keep the alcoholic strength between 10 DEG  and 20 DEG G.L. from the top to the bottom of the column.  Column C is heated by steam raised, in heat-exchanger O, from residual water withdrawn from the base of rectifying column M, the heating medium being the alcoholic vapour leaving the head of column M. Impurities are expelled from the head of column C and are partly condensed in condensers E and F, the condensate being collected in vat G.  Acetaldehyde and acetone pass on to pump D, and are collected in absorber H.  Phlegm containing only traces of impurities is pumped from the base of column C into an intermediate section of column M.  Pure rectified alcohol (96 G.L.) is taken off from column M through pipe 17, while the impurities are removed through pipes 14 and 16.  Some of the impurities may also pass overhead from column M, and are withdrawn via line 15.  Cool water is added to the impurities in vat G, and the waterinsoluble components thereby form a separate layer which is withdrawn from the system. The aqueous layer from vat G is pumped, together with the liquid from absorber H, to column P, from which the impurities are taken overhead, and withdrawn from condenser L via pipe 11.  Water is discharged from the base of column P.  Specifications 626,658, 683,781 and 718,899 are referred to.

Title: Improvements in or relating to sponge rubber and products manufactured therefrom
IPC: D06N3/00
Filed: 1937-09-20
Abstract: 502,733. Microporous films and coatings. BINNS, W. Sept. 20, 1937, Nos. 25500/37 and 8802/38. [Class 70] [Also in Groups III, IV, and VIII] Microporous films, skins or coatings are made by coating or spreading a support with a dispersion of rubber or other film forming substance in the state of a smooth cream-like foam, applying a powdered substance to the foam and causing the foam to collapse to the desired thickness and subsequently to set, the powdered substance being thus caused to enter into the foam structure so as to maintain the reticular nature of the structure. The powdered substance may be finely divided fibres, e.g. wool, rayon, cotton, jute or hemp, talc, calcium sulphate, or mixtures of these. When a dispersion of rubber is used it is preferably treated by incorporating a polymerized aldehyde as described in Specification 477,826 so that by heating the foam, e.g., to slightly above 100‹ C. segregation of the serum may be effected prior to the collapse of the foam. The foam may be collapsed to the desired thickness by applying light mechanical pressure, e.g., by rotating brushes, rollers or scrapers. After the collapse of the foam, it is heated or otherwise treated to cause the rubber to set by coagulation and vulcanization. A coating of paint, lacquer, varnish or the like may be applied to the set film or skin. The invention is particularly applicable for producing coatings on the backs of woven or knitted fur fabrics to produce imitation pelts or skins. The foam may also be spread or coated on porous moulds or formers, treated in accordance with the invention and stripped, to produce microporous sheets, gloves and other articles. Instead of rubber dispersions, aqueous dispersions of natural and synthetic resins, of cellulose and cellulose derivatives, or of drying oils or the like may be used. In an example, 100 cc. of a 33 per cent aqueous dispersion of acrylic resin and 10 cc. of a 5 per cent aqueous solution of methyl cellulose, are whisked to a foam, 2 gms. of powdered methyl cellulose being added during the whisking operation, and the foam is spread on to fabric or other backing, powdered substances applied and the foam heated and mechanically compressed.

Title: Improvements in pressure control systems
IPC: F15B11/02
Filed: 1929-08-22
Abstract: 338,947. Triggs, W. W., (Scovill Manufacturing Co.). Aug. 22, 1929. Press working valves; presses, relief and safety devices for.-A pressure control system, particularly applicable for controlling the pressure supplied to a hydraulically-operated extrusion press, comprises a plurality of pressurelimiting means operating to relieve main line pressure at successively higher critical pressures and means situated between the relief units for rendering the pressure-limiting means below a desired critical pressure ineffective. The invention is described in connection with the hydraulic system for operating an extrusion press described in Specification 338,946. Each of the pressures-relieving valves comprises a lift valve member 722 adapted to be moved to and from an annular seat 721 by a screw-threaded spindle 723 engaging a nut formed in a detachable member 725. The spindle is supported in a bearing 726 and carries a disc 735 having a spring coupling with a pinion 730 meshing with a rack 731 on a spindle 705. The spindle bears at one against the actuating plunger and at the other is furnished with a piston 706 working in a loading cylinder 707. This cylinder contains water and is connected by a pipe 708 to a point near the bottom of a reservoir containing water and compressed air. A leaky non-return valve 710 in the pipe 708 permits a more rapid flow in one direction than in the other. To compensate for the friction of the stuffing box 704 a pair of compression springs 752 mounted on pillars 750 are arranged to bear against a cross head 751 engaging a block 754 on the rack. The relief valve operating at the lower pressure has its outlet controlled by a valve 742 adapted when moved into engagement with an annular seat 741 to close the outlet and so render the relief valve ineffective. The valve 742 is actuated by a power cylinder under the control of an electrically-operated pilot valve, the electric circuit of which is closed when the hydraulic working valves are operated to admit pressure-fluid to the. rams requiring the higher pressure. To prevent the sudden building up of pressure the high-pressure relief valve has a supplementary relief valve arranged in a byepass. This valve is shown in Fig. 5 and comprises a, spring loaded lift valve member 767 engaging a tubular seat member 762 to which inlet pressure is admitted by a pass 764 and port 774. The seat member is adjustably mounted in a cage by a screwed stem 770 secured by a locking screw 771. Specification 338,898, [Class 135, Valves &c.], is referred to.
