Title: Improvements in or relating to processes and apparatus for the production of aluminium, beryllium, magnesium, alkali earth or alkali metals by electrolysis of fused starting materials
IPC: C25C3/00
Filed: 1938-03-16
Abstract: 500,509. Electrolytic productionof aluminium &c. GES. ZUR VERWERTUNG CHEMISCH TECHNISCHER VERFAHREN, VADUZ. March 16, 1938, No. 8105. Convention date, March 16, 1937. [Class 41] In a process for the production of auminium, beryllium, magnesium, alkali earth or alkali metals by electrolysis of fused starting materials wherein there is employed a cathode formed by a metal in fusion heavier than the electrolyte and capable of absorbing the metal to be prepared as an alloy, and on the other hand, in a second electrolysis, in which this alloy acts as anode, of releasing the metal by electrolytic decomposition, continuous circulation is set up between the parts of the absorbing metal which serve as anode and cathode respectively by us - ing the convection currents caused by the thermal actions that accompany the pass. age of the electric current through the metal in fusion in pipes connecting these two parts of the absorbing metal. In one embodiment, halogen is produced at the anode 3 by electrolysis of the molten electrolyte in vat 1, and the metal produced is absorbed in'the molten metal cathode in the lower vat 4. Owing to the heating up produced in two pipes connecting the lower vats 4 and 5 (which are inclined in opposite directions and one only (10) of which is shown) by the passage of the current, the overheated metal rises in the said tubes, and the alloy containing the metal produced in vat 1 is thereby transferred from vat 4 to vat 5 through the tube not shown, and replaced by molten metal rising from vat 5 through the tube 10. The alloy then operates as anode and loses the metal produced by electrolysis in vat 1, which collects round the hollow cathode 8 at the surface of the electrolyte in vat 6. The cathode 8 has lateral openings 11 slightly above the surface of the electrolyte, but is occasionally lowered to immerse these openings slightly and permit influx of mixed electrolyte and metal, after which it is again raised to allow the said mixture to separate. The vats, cathode, and tubes may be cylindrical or of any other shape, the vats may be separate or formed by dividing a single chamber by a partition, and more than two tubes may be used.

Title: Improvements in or relating to the manufacture of titanium dioxide
IPC: C01G23/053
Filed: 1940-05-14
Abstract: 542,579. Titanium dioxide pigments. ABBEY, A. (Titan Co., Inc.). May 14, 1940, No. 8672. [Class 1 (iii)] In preparing titanium dioxide pigments by decomposing a titanium solution by hydrolysis in presence of a sol of titanium dioxide, the sol is prepared by precipitating titanium dioxide from a solution of a titanium salt containing polyvalent anions, removing the polyvalent anions from the precipitate and peptizing the precipitate at ordinary temperature with an acid, the anions of which are univalent and diluting the sol so that it contains À5 to 50 grams of titanium dioxide per litre. In an example, titanium hydrate paste precipitated from titanium sulphate solution is suspended in water and neutralized with ammonia. The suspension is repeatedly diluted with water and filtered to remove ammonium sulphate and the precipitate is treated with hydochloric acid solution and afterwards heated to 90-95‹ C. The hot sol is poured into hot titanium sulphate solution. The peptizing may be effected by titanium tetrachloride or by nitric acid and in the latter case sufficient trivalent titanium must be present to be able to reduce the acid. Removal of polyvalent anions may be effected by use of substances such as barium or strontium compounds which form insoluble compounds. By effecting hydrolysis in presence of extenders or fillers such as barium carbonate or sulphate, silica or calcium sulphate, composite pigments are obtained. Specifications 405,669 and 533,227 are referred to.
