Title: Extraction of aluminium from aluminium-bearing dross
IPC: C22B7/04
Filed: 1972-08-07
Abstract: 1431898 Obtaining aluminium from dross ELECTRICITY COUNCIL 30 July 1973 [7 Aug 1972] 36825/72 Heading C7D Aluminium is recovered from aluminium-bearing drosses which have first been mechanically beneficiated by a process which comprises melting a heel of aluminium in a coreless induction furnace, feeding the aluminium-bearing dross into the furnace, adding a flux and removing aluminium which accumulates below the level of non-metallic material floating on the surface of the melt. The process may be continuous, with excess dross being periodically withdrawn and aluminium also being drawn off. In non-continuous processes, the inductive stirring effect causes the non-metallics to adhere to the furnace walls from where they are removed by scraping. In a tilting furnace the dross can be removed by a rake and the aluminium then poured out by further tilting. Ferromagnetic materials should be separated magnetically prior to treatment of the aluminium dross.

Class 40(7) In a radio direction-finding receiver, signals, the frequency of which is indicative of the bearing of the receiver from a transmitter, are received on an omni-directional aerial 10 and are passed to two channels, the first including a filter 13 sharply tuned to the carrier frequency, and the second including a wide-band filter 11 which passes the carrier and the side-band frequencies. The channels feed to an amplitude modulation detector 12 whose output is passed to a frequency detector 15 which is coupled to an indicator 16 to indicate the frequency and hence the bearing. Also according to the invention, a radio beacon system includes a receiver as described above and a radio beacon which emits a beam comprising a carrier modulated by a sub-carrier, the subcarrier being frequency modulated in accordance with the azimuthal direction of the beam so that differing directions of azimuth are characterized by differing values of the frequency of the subcarrier. The beacon comprises an aerial 1 rotated in azimuth by a motor 2 which is also coupled to a variable frequency source 8. The instantaneous frequency of this source is characteristic of the instantaneous direction of the aerial 1. Source 6 generates the sub-carrier which is frequency modulated in unit 7, the resultant output modulating the carrier from source 4 in amplitude modulator 5.

Title: Process for recovery of uranium and vanadium from carbonate solutions by reduction precipitation
Inventor: ELLIS DAVID ALLEN
IPC: C22B34/22
Filed: 1954-12-31
Abstract: Solid material containing uranium and vanadium values, particularly carnotite ore, is leached with an alkali metal carbonate solution and the uranium and vanadium values are precipitated from the leach solution, to render the latter recyclable, by contact with a sodium amalgam containing 0,01 to 0,5% of sodium therein.  In the case of carnotite, the ore may be roasted at 500 DEG C. and thereafter leached, or if the vanadium content is high, the ore is roasted with 10% by weight of common salt.  The amalgam must be contacted intimately with the leach solution and oxygen must be excluded.  The uranium- and vanadium-containing precipitate may be dissolved in 6M hydrochloric acid in the presence of an oxidizing agent such as sodium chlorate and the uranyl chloride complex formed thereby is absorbed on an anion exchange resin.  Absorption of vanadium is reduced by treating the leach solution with sulphur dioxide gas to reduce the vanadium before contact with the resin.  Impurities may be selectively removed from the resin by washing with 6M hydrochloric acid and the uranium thereafter eluted with water to yield a uranyl chloride solution.  Ammonium is then added to the eluate to precipitate uranium and the precipitate is heated in air to convert it to U3O8.  The amalgams may be prepared by the addition of sodium to mercury overlaid with xylene, or by electrolysis, but preferably the reduction is effected in an electrolytic cell having a mercury cathode, the electrolyzing current being such that the amalgam is maintained at the required strength.  Specification 886,394 is referred to.

Abstract: 511,826. Regulating. BAYERISCHE MOTOREN WERKE AKT.-GES. Dec. 30, 1938, No. 37879. Convention date, Dec. 31, 1937. [Class 7 (vi)] In aircraft engines having two superchargers, one of which is driven from the engine shaft and the other by an exhaust-gas turbine, the latter being brought into action only after a predetermined altitude has been reached, a throttle controlling the inlet to the enginedriven supercharger is connected to throttles controlling the exhaust so that the latter throttles remain unaffected up to a predetermined opening of the first-mentioned throttle. Fig. 1 shows an engine 2 driving the first supercharger 1, to which air is supplied through a pipe 12 and the exhaust-driven turbo-blower 13 and cooler 14. Until the predetermined altitude is reached, a pair of throttle valves in the exhaust manifold actuated by a pair of levers 9 is kept open, so that the exhaust passes directly to atmosphere and the blower 13 is not driven thereby. When the altitude is reached, the exhaust, throttles are closed, so that the exhaust passes to the turbine and drives the blower 13, which then supplies precompressed air through the cooler 14 to the supercharger 1. The throttle levers 9 are connected through a lost-motion device 21 to rods 8, 7 connected through a second lostmotion slot 6 to the lever 5 of the throttle 3 of the supercharger 1, so that when the throttle 3 is opened an amount corresponding to the predetermined altitude, the exhaust throttles are closed. A speed regulator 18 is connected by a link 19 to a toggle joint 20 in the rod 8, so as to open the exhaust throttles when the speed of the turbo-blower becomes excessive.
