Abstract: 629,561. Cage lifts. BRITISH THOMSONHOUSTON CO., Ltd., and OLDHAM, T. J. F. April 28, 1947, No. 11310. [Class 78 (iii)] In a gearless lift driving mechanism independent manually operable means are provided for moving the cage under emergency conditions which prevent the lift from slipping due to unbalance between the lift weight and the counterweight during the movement. A worm wheel 11, Fig. 1, is keyed to the shaft on which the driving sheave 1 is mounted, and a worm 8 mounted in bearings 9, 10 is engaged with it. A manually operated lever may be applied to square end 12 of the worm shaft. The worm gearing may be irreversible to prevent slip or alternatively ratchet means may be provided. The worm and worm wheel may be associated with idler 2 instead of sheave 1. In operation the brake on the driving sheave is set while the worm is engaged and then released. In a second embodiment wherein the brake on the driving sheave remains set, the ends of the hoisting rope 5 instead of being connected to separate anchorages 6, 7 are passed over idler pulleys so that the ends are brought together and connected to a joint block 16, Fig. 3, normally secured to a fixed beam 17 by a screw 17<SP>1</SP>.

Title: Recovery of uranium, aluminium and iron values
IPC: C01G1/06
Filed: 1957-04-09
Abstract: <PICT:0855811/III/1> Uranium, iron and aluminium values are separately recovered from an ore containing them by chlorinating the ore to form a volatilized stream of metal chlorides which are contacted with granular alumina to deposit uranium values thereon; the remaining gases are then contacted with ferric oxide to convert the aluminium chloride to, and deposit as, aluminium oxide, and the remaining iron chloride-containing vapours are oxidised at about 1000 DEG C. to produce ferric oxide.  As shown in the Figure, a shale is heated in steam or combustion gases to 450-800 DEG C. to drive off volatiles and thereafter chlorinated with carbon tetrachloride, phosgene, chlorine or, preferably, a mixture of chlorine and sulphur monochloride.  After separating solids, the vaporized chlorides are condensed at 100-300 DEG C. and the uncondensed titanium, silicon and sulphur chlorides together with excess chlorine is recycled.  The condensed chlorides are then re-evaporated at 600-1000 DEG C. and passed through granular alumina at 300-1000 DEG C. whereby the uranium is deposited on the alumina. The uranium values are recovered from the alumina by treatment with nitric or sulphuric acid and the uranium salts so formed are separated from the liquid phase by extraction with a selective organic solvent such as benzylamine or diethyl ether. Alternatively gaseous fluorine may be passed over the alumina to volatilize the uranium as the hexafluoride.  The vapour stream leaving the alumina bed, consisting of iron and aluminium chlorides is passed over ferric oxide at 400-700 DEG C. whereby the aluminium chloride is converted to alumina which is collected, and the ferric oxide is converted to ferric chloride which is vaporized into the chloride stream.  The alumina so formed may be recycled to the uranium separation step.  The ferric chloride stream is then converted to ferric oxide by oxidation with oxygen, and the chlorine is recycled.

Abstract: 527,649. Valve circuits; wireless receiving apparatus. KRAMOLIN, L. DE. April 17, 1939, No. 11631. Convention date, April 30, 1938. [Class 40 (v)] The resonant frequency of a high frequency circuit is varied by varying the direct current component of the discharge path of a gas or vapour-discharge tube acting as a variable inductance in the said circuit. In the Figure, the neon tube V<SP>1</SP> is connected across the inductance L of the frequency determining circuit of an oscillator V2 back-coupled at L1. The inductive effect of V1 is varied by varying its discharge current by means of a slider on potentiometer R. The condensers Cl, C2 are so chosen that sawtooth oscillations at any frequency near to the working frequency are not set up ; the tube is also shunted by an inductance for that purpose. The tube may itself act as an oscillator and its oscillating properties at high frequencies may be stimulated by using a gas filling of low atomic weight, e.g. hydrogen ; or a separate auxiliary amplifier may be provided. The invention is specially applicable to remote control of tuning and automatic frequency and selectivity control. Specifications 386,356 and 408,943 are referred to.
