Title: Process for recovering an ascorbic acid compound
IPC: C07D307/62
Filed: 1946-05-29
Abstract: Ascorbic acid is obtained from a solution of an ascorbic acid compound of the class consisting of ascorbic acids and desoxy ascorbic acids, in aqueous hydrohalic acid, preferably aqueous hydrochloric or hydrobromic acid, by treatment with a basic divalent lead or silver compound, e.g. plumbous oxide, plumbous carbonate and silver oxide, filtering off the insoluble halide thus formed and recovering an aqueous solution of the ascorbic acid compound essentially free from hydrohalic acid.  After precipitation and filtering off of the major portion of the lead halide the remainder of the lead may be removed from solution as lead sulphide by treatment with hydrogen sulphide.  Prior to treatment of the solution with the divalent-lead or silver compound the concentration of the ascorbic acid compound is reduced by diluting with water or by first crystallizing out the compound and diluting the mother liquor. Detailed examples are given.

Title: Improvement in process and apparatus for the electrolytic production of materials
IPC: C25C3/06
Filed: 1949-06-21
Abstract: 674,157. Fused-electrolyte processes. LUZZATO, B. B. A. June 21, 1949 [June 28, 1948], No. 16495/49. Class 41. A method of performing an electrolytic process in which the electrolyte is maintained in a molten state and heated gaseous products are evolved includes the step of concentrating the heat values obtainable from the evolved gases over a portion of the surface of the electrolyte to maintain said portion in substantially molten condition while subjecting the electrolyte to electrolysis, whereby raw materials may be fed to said molten area or products of reaction withdrawn therefrom. The gaseous products may be combustible and may be burned near to the portion of the surface. They may be supplemented by gases from an extraneous source. In the construction shown in Figs. 3 and 4, for use in the production of aluminium, a double-ring chamber is formed about an electrode 2, comprising a casing 12, a horizontal plate 15, and a hinged plate member 16 which extends downwardly almost to the surface 17 of the electrolyte. Partitions 37 formed with openings 38 separate off a compartment 35 into which depends a burner attachment 21 through an opening in the plate 15. The attachment comprises a housing 24 provided with a conduit 25 and with a conveyer 27 inside a tube 26 formed at the bottom with an enlarged outlet. Gases given off around the electrode 2 during electrolysis are collected in the compartment 35 and pass through a duct 33 to a zone 39 where they are mixed with air supplied through ducts 31. The gases are ignited at the zone 39 and the products of combustion are drawn by suction through the annular space surrounding the conveyer tube 26 and through an outlet 34. The heat prevents the surface 40 of the electrolyte from forming into a crust and also pre-heats the raw material which is fed into the apparatus by the conveyer 27. In the construction shown in Figs. 9 and 10, the electrode 76 is provided with a vertical slot 77 and is fitted with a casing 78 to form a zone 79, within which is mounted a burner assembly and a conveyer tube 84. Gases collect in a compartment 90 of a double-ring chamber around the electrode 76, and flow through ducts 96 into a chamber 87, together with air through pipes 97. The gas mixture is ignited whereby the surface of the electrolyte below a plate 81 is kept in the molten state and raw material fed through the conveyer 85 is pre-heated. In a further construction shown in Fig. 11, the conveyer tube is replaced by a slidable tube 105 through which aluminium is removed, the aluminium being kept molten by heat exchange arising from combustion of the gases. The tube 105 may be detachable, in which case it may be replaced, when necessary, by a tube for the supply of raw material to the bath.

Title: Improvements in the production of esters of gamma-chlorobutyric acid
IPC: C07C69/63
Filed: 1952-07-04
Abstract: Gamma-chlorobutyric acid esters of mono-or polyhydric alcohols (see Group IV (b)) are employed in softening polyvinyl chloride foils. Specifically referred to are esters derived from hexanol, cyclo-hexanol, ethylhexanol, benzyl alcohol, glycerol, pentaerythritol, hexanetriol, di-or triethylene glycol.ALSO:Esters of gamma-chlorobutyric acid are produced by a process which consists in leading dry hydrogen chloride into a boiling mixture of about equivalent amounts of gamma-butyrolactone and monohydric or polyhydric alcohols diluted with a diluent which forms azeotropically boiling mixtures with water whereby the water formed is removed continuously in the form of a water-diluent azeotropic mixture. Alcohols mentioned are hexanol, cyclohexanol, ethylhexanol, benzyl alcohol, hexanediol-1 : 6, di- and triethylene glycol, hexanetriol-1 : 2 : 4, pentaerythritol or glycerol.  Diluents mentioned are methylene chloride, ethylene chloride, benzene or toluene.  The diluent is preferably recycled to the reaction vessel after removal of water from the azeotropic mixture distilled.  In an example, gamma-butyrolactone, hexane-diol-1 : 6 and toluene are boiled under reflux whilst dry hydrogen chloride is led in.  A water-toluene azeotropic mixture is distilled off and after separating the water toluene is recycled.  The product, apparently the bis-gamma-chlorobutyric acid ester of hexanediol-1 : 6, on completion of the reaction is washed and decolorized.  Polyvinyl chloride foils are softened with this oil.  Similar products are obtained if instead of hexanediol-1 : 6 equivalent amounts of hexanol, cyclohexanol, ethylhexanol, benzyl alcohol, glycerol, pentaerythritol, hexanetriol or di- or triethylene glycol are used.

Abstract: 334,254. Kent, W. J. May 31, 1929. Milling helical surfaces. - In a machine for generating cams of the type used in steering gear, and adapted to be engaged by one or more pegs or rollers constrained to move in a non- rectillinear path, motions relatively at right angles are imparted to the work-holder and toolholder, the resultant relative motion being along the said non-rectilinear path. The blank 1 is mounted on mandrels between bearings 2, 3 on a slide 4 mounted on the bed 5, and is rotated from a belt pulley 26 through gearing 25 and a shaft 24. A cam 7 is rotated from the same source through gearing 23, a shaft 19 and bevel gearing 21, and is held by a spring 8 against a roller 6 on the work slide, whereby an axial motion is imparted to the work in timed relation with its rotation. A tool-holder 11, carrying a milling-cutter of similar profile to the peg or roller slides in vertical slides 12, and has a slot 14 engaged by a peg 15 on an arm 16 which is rotated by worm gearing 18 from the shaft 19, a vertical motion being thus imparted to the toolholder. Depth of cut is initially adjusted by a hand-wheel 13, and may be increased towards the ends of the cut by causing the tool-holder to approach the work under cam action. To allow the worm of the worm-drive to drop out of engagement at the end of the operation a rod 30<1> carried by the slide 4 is adapted to rock a latch member 30 which normally supports the worm shaft. The machine mav be modified to move the tool-holder parallel to the axis of the work and the work holder at right angles thereto and to its own axis.
