Title: Improvements in or relating to electrolytic cells
Inventor: SZECHTMAN JOSHUA
IPC: C25C7/00
Filed: 1962-07-13
Abstract: A fused electrolyte process, particularly for decomposing alkali and alkaline earth metal halides, comprises feeding molten metal, e.g. lead, through conduit 80, to a hermetically sealed horizontally disposed electrolytic cell having an electrolysis chamber containing one or more horizontal anodes 31 and communicating at the rear (right) beneath a transverse wall 22 with a dross-removal and outlet chamber 12, preferably subdivided by further transverse wall 21, having a U-shaped outlet 52 (see Fig. 6, not shown) for withdrawal of dross and an outlet 57 for molten metal, feeding molten anhydrous metal halide to the electrolysis chamber, e.g. through pipe 44 by way of self-regulating float valve 47, at rate equal to that of electrolysis whilst passing an electric current between the anodes and molten metal cathode 13, controlling the molten metal level in the electrolysis chamber to maintain a constant gap between electrodes and periodically interrupting the current whilst varying the molten metal level to temporarily (a) raise it to contact and scour the anode under-surfaces, or (b) lower it to allow electrolyte to escape from the electrolysis chamber to carry dross 53 therefrom and then raise it to expel dross through the outlet 52, and withdrawing the molten metal, e.g. lead/sodium alloy, through the outlet 57.  The molten metal level within the cell is preferably varied by controlling the rate of withdrawal of metal from the cell, e.g. by raising and lowering a sleeve 58 closely fitted with a slide ring 69 for covering a plurality of holes in the sleeve wall towards the bottom and engaging in valve-tight manner with the outlet 57, whilst maintaining a constant feed rate of molten metal to the electrolysis chamber. The molten metal withdrawn <PICT:1007778/C6-C7/1> may be heated by a burner 76 in a retort 75 to distil off metal alloyed therein, e.g. sodium, the stripped molten metal, e.g. lead, being recycled via pump 78 and conduit 77 back to the electrolysis chamber.  Each anode 31 may be supported by four holder bars 35 keyed into a common graphite conductor plate 26 which forms the roof of the cell and is provided with a gas outlet 55, e.g. for chlorine.
Patent GB-914987-A (GB)
Title: Improvements in containers
Inventor: WARREN FREDERICK WILLIAM
IPC: B65D30/08
Filed: 1958-08-22
Abstract: The container portion of a transportable bag for liquid hydrocarbon fuel is formed of a flexible composition which, after vulcanization, is inserted in an outer cover of textile material thereby constituting the bag.  The container may be made by dipping a removable porcelain or metal former first into a liquid coagulant and then, one or more times, into a latex.  The flexible composition may be made entirely of a butadiene/acrylonitrile copolymer, or a layer of this copolymer may be covered by a layer of a different synthetic rubber or by a layer of natural rubber. Various blends of latex are described.  The coagulant may be a solution of either zinc chloride, calcium chloride or aluminium chloride in methylated spirit.  The dipping former may be first immersed in the latex and the film of latex so produced then set in the coagulant.  In an alternative method, a non-removable former of fabric, e.g. nylon or polyethylene terephthalate, is used, and the fabric is coated with a solution of an oil-resistant elastomer, e.g. neoprene.  The lining is inflated with a gas, and the resultant former is sprayed with a latex while it is suspended and rotated in warm air.  The layers of elastomer so formed are vulcanized, and the container is turned inside out so that the fabric layer is outermost.  The container is then inserted into a fabric cover to form a transportable bag.

Title: Method for manufacturing organic nitro compounds
IPC: C07C203/04
Filed: 1952-11-05
Abstract: <PICT:0735888/IV (b)/1> <PICT:0735888/IV (b)/2> In a process for the manufacture of organic nitro compounds, e.g. nitroglycerine by nitration with nitrating acid, the heat content of the reaction components is adjusted to a value suitable for the nitrating reaction and the components are brought together in an injector into which the nitrating acid is introduced under pressure, the other reaction component being drawn by suction from a supply container into the injector under such conditions that the mixing of the reaction components and the reaction take place instantly and substantially completely immediately in the injector and thus within a very limited volume, whereupon the reaction mixture is transferred to a separator where the nitro products produced are separated from the remaining acid (waste acid).  A portion of the waste acid, if required after cooling or heating is re-introduced into the process by adding to the nitrating acid.  In the Figure glycerine is supplied through conduit 2 and heat exchanger 24 to the injector 1 and nitrating acid which may comprise 40-65 per cent HNO3 and 60-35 per cent H2SO4 is supplied to an injector mixer 4 where it is mixed with waste acid which is recycled from the separator 10. The mixture of nitrating acid and waste acid is cooled in the cooler 7 to between +5 DEG  C. and -20 DEG  C. and the cooled mixture then introduced under pressure into the reaction injector 1.  The injector (Fig. 2) consists of a circular Venturi-shaped chamber 20 into which projects a conical nozzle or injector jet 21 for supplying the nitrating acid under pressure.  Between the jet 21 and the wall of the chamber 20 is an annular space 201 into which the glycerine supply conduit discharges. In front of the discharge opening of the venturi chamber is a perforated plate 22 beyond which the injector is prolonged with a cylindrical discharge member 23.  The reaction takes place substantially completely in the venturi chamber and is discharged into a chamber 25 from which it passes to the separator 10 which is equipped with a cooling coil.  If desired, separation-promoting agents may be added to the mixture via the chamber 25.  The upper nitroglycerine layer is then passed to the washing plant comprising three washing units each composed of an injector 13, into which washing liquid is supplied through conduit 14, and a separator 15 from which waste washing liquid passes out through the conduit 16. The washing may be carried out with water or with water containing a weak alkaline substance such as ammonia, soda, or sodium bicarbonate and the washed nitroglycerine is removed through conduit 17. Reference is made to using glycol instead of glycerol and examples of other nitro compounds which may be produced are dinitrodiethylene glycol, ethyl nitrate, mononitrobenzene and mononitrotoluene.
