Title: Improvements in or relating to the purification of alumina
IPC: B60R16/00
Filed: 1958-09-05
Abstract: 895,447. Purifying alumina. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES. Sept. 5, 1958 [May 10, 1958], No. 2534/62. Divided out of 895,446. Class 1(3) Titanium-containing impurities are removed from alumina baths prepared by the carbothermal purification of aluminium ores, by adding to the molten bath a boron compound capable of forming boro-titanium in an amount sufficient to react with at least a major proportion of the titanium impurities, and in which the resulting boro-titanium is then separated from the alumina bath. Suitable boron compounds include anhydrous borax, boron carbide, boracite, and boric acid. The present process is particularly suited to the removal of titanium from the molten alumina baths obtained by the process of Specification 895,446, wherein an aluminium ore is reduced with carbon at above 2000‹ C. in an electric arc furnace, in which in the initial phase of the reduction an excess of carbon is present, and a further quantity of carbon is added before the alumina is cast to complete the purification. Globules of ferro-silicon in the bath may be removed by the addition of iron, the surface of the bath being first heat-insulated by a layer of powdered alumina. Excess carbon and aluminium carbide may be removed by the action of oxygen, for example by blowing a jet of air across the casting stream, thereby at the same time dispensing and granulating the purified alumina to form hollow globules, which are collected in water. A small quantity of magnesium oxide may be present as a flux.

Abstract: 710,345. Bridge networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 30, 1951 [Feb. 2, 1951], No. 2698/51. Class 40 (8) A bridge network consists of four arms, two opposite arms including a T-shaped assembly of stubs Z1, Z2, Z3, Z1R, Z2R and Z3R, one other arm containing a pair of terminals O, and the remaining arm containing a balancing impedance R, terminal pairs being also included in one or both diagonals of the bridge, and the impedances and connections of the bridge being coaxial tubular structures. The impedances of one set of stubs are arranged to be the reciprocal of those of the other set. The practical form of the network is shown in Fig. 2, which is electrically equivalent to Fig. 1 though no geometrical T- shaped assemblies appear. One assembly consists of a coaxial impedance Z3R which branches into an inner coaxial impedance Z2R and an outer Z1R, thus forming the equivalent of one T assembly. The other assembly is formed from sections Z3, and Z1 and Z2. Impedances Z1 and Z-R are adjusted by axial movement of their central conductors 13 and 15 which include insulating portions 1NS. By employing only two pairs of terminals, the apparatus may be used as a filter. By using all three pairs the network may mix two inputs in a single output or provide two split outputs from a single input.
