IPC: H01M50/451
Filed: 1927-11-30
Abstract: 281,674. Jaubert, G. F. Dec. 1, 1926, [Convention date]. Diaphragms; oxygen and hydrogen, obtaining; electric endosmose. - A diaphragm particularly for use in the generation of oxygen and hydrogen by electrolysis of an alkaline solution consists of perforated sheet metal, wire gauze, asbestos cloth or other material on which and in the interstices of which is deposited a hydrogel of an organic or inorganic colloid. The finished diaphragm must be permeable to the electrolyte but impermeable to the gaseous products and resistant to the chemical action of the electrolyte. The hydrogel may be applied as a paste or may be formed in situ by dipping the base first into a suitable solution e.g. a solution of magnesium chloride or sulphate and then into a , coagulating solution, e.g. a solution of sodium silicate. Alternatively the colloid may be deposited on the base by preliminary electrolysis, for which purpose 5-10 per cent of the colloid, estimated as dry substance, is suspended in the working electrolyte. When an electrolyte of sodium or potassium carbonate is employed, the hydrogel may consist of hydrocarbonate of magnesia. A little colloidal material may be added from time to time to the electrolyte during working to make up for accidental loss of diaphragm material. The following are suitable colloids, viz., magnesium silicate, iron silicate, kaolin, ferric hydrate, natural or artificial yellow ochre, limonites, clays, magnesium or aluminium phosphate, graphite, carbon from blood, india-rubber, hydrates of alkaline earth or rare earth metals, and copper, nickel or other metal in flocculent form. When out of use, the diaphragm should be washed and then dipped in a 50 per cent glycerine solution in order to prevent drying.

Abstract: 1,196,145. Laminate. INTERNATIONAL PAPER CO. 13 July, 1967 [27 March, 1967], No. 32309/67. Heading B5N. A continuous process for coating a web of dielectric material with a plastics material comprises directing the web and an extruded film of the material along paths which converge, and subjecting the film in the region of convergence to the action of an electric field to force the film into bonding contact with the web, the region of the electric field being of a lesser width than that of the web. As shown, in the region between rolls 30 and 32, the web 20 contacts the rounded edge of a bar 31. The length of the bar 31 is less than the width of the web, thus restricting the electric field to a central region of the web, bonding taking place in this central region only. An electrode structure 37 produces the electric field in this region to bond the extruded film 36 to the web. The bar 31 may be electrically grounded or connected to a positive or negative potential source. The web may be of paper. The film may be of any of the polymers and copolymers of propylene, ethylene and butylene or of polystyrene. The lateral edges of the laminate, to which edges the film will not have been bonded, may be trimmed.

Filed: 1952-12-23
Abstract: In concentrating plant wherein the liquor being evaporated is circulated between <PICT:0742715/III/1> a heater and a liquid/vapour separation vessel, the fresh feed liquor is supplied to the plant at a temperature and pressure greater than the temperature and pressure of the circulating liquor and is introduced in part into the inlet side of the heater, and in part directly into the separation vessel. Part of the preheated liquor may also be injected into the return pipe leading from the heater back to the separation vessel.  The invention permits high circulation rates to be maintained without the formation of so much vapour in the heater that the heat-exchange surfaces are no longer adequately wetted with liquor.  The concentration of spinning bath liquors is referred to.  In the Figure, separation vessel 20 is connected by pipes 23, 24 to heater 25 which is provided with supply and discharge pipes 26 and 27 respectively for heating medium.  The feed liquor pipe 28 branches into two pipes 30 and 31, of which pipe 30 opens into the inlet end of heater 25, while pipe 31 branches into two further pipes 33 and 34.  Pipe 33 opens into the vapour space of the separation vessel 20; a pipe 34 leads to a jet 35 disposed in the nozzle-shaped return pipe 24.  Valves 36, 37 and 38 enable the distribution of feed liquor to be varied between the various pipes.  Vapours leave the separation vessel via pipe 21; and the concentrated liquor is discharged through pipe 22.
