Title: Improvements in and relating to uranium extraction processes
IPC: C01G43/00
Filed: 1958-12-15
Abstract: In the extraction of uranium values from liquors obtained by leaching uranium ores with aqueous alkali-metal carbonate solutions, the liquor is ozonised and filtered to obtain a solution which, after any necessary adjustment, has a pH of 9.5-11.5, a carbonate concentration calculated as Na2CO3 of less than 30 g.p.l., a bicarbonate concentration calculated as NaHCO3 of less than 15 g.p.l., and a sulphate concentration calculated as SO4 of less than 6 g.p.l., and this solution is contacted with an anion exchange resin.  The barren solution may be recycled to the ore leaching step.  The uranium adsorbed as a tetravalent uranyl carbonate is recovered by elution, for example, with sodium nitrate or chloride.  The eluate thus obtained may be acidified and a salt having the same anion as the eluant added to precipitate insoluble salts.  For example, a calcium salt may be added, such as calcium nitrate when sodium nitrate is the eluant.  The acid employed for the acidification may also have the same anion as the eluant.  The precipitated salts may be removed by filtration, the uranium salts in the resulting solution extracted by an immiscible solvent, for example, a mixture of paraffin and tributyl phosphate, and the remaining aqueous solution neutralised by the addition of a substance having the same cation as the eluant, for example sodium hydroxide.  The resulting solution may be employed to elute further quantities of uranium from the anionexchange material. The uranium values may be extracted from the organic solvent as araryl nitrate or chloride for example, by means of water.  A suitable rate of ozone supply in the initial ozonising step is from 1 to 6 grams of ozone per hour for a rate of solution supply of 40 litres per hour.  The ozonisation is preferably carried out at room temperature for a period of 10-15 minutes, and the ozone is conveniently introduced by means of a microporous diffuser formed of fritted silica or carborundum, or of agglomerated carbon.  The filtration after ozonisation is normally carried out in the presence of powdered filtering aids, such as diatomaceous earth, asbestos, or silica.

Title: Electrical Drives with Motor Energizing Systems
IPC: G05B19/416
Filed: 1967-09-05
Abstract: 1,188,328. Control of motors. GERBER SCIENTIFIC INSTRUMENT CO. 5 Sept., 1967 [8 March, 1967], No. 40439/67. Heading H2J. In a speed control system for an electric motor 32, which may be a stepping motor, a linear function generator 10 produces a ramp signal 14 in response to command signals on line 22. A shaping network 24 converts the signal 14 to a signal 26 having non-linear ramps and which is used to drive the motor so that its speed is directly related to the magnitude of the signal. The signal 26 is transmitted to a voltage-controlled oscillator 28 producing driving pulses for the motor at a frequency determined by the signal. The shaping network 24 is connected-to a source of reference voltage as well as the line 12 so that the output voltage increases at a progressively lower rate, when the input voltage increases at a linear rate, due to the diodes 56 becoming operative in sequence. To account for friction, the linear function generator 10 may be modified to produce a signal 60 whose up-ramp 62 is of lesser slope than the down-ramp 64. The shaping network 24 then produces a resultant signal 66 having ramps of different average slope whereby upramp 66 occupies a greater amount of time than the down-ramp 70. In an alternative arrangement, the generator 10 is associated with two separate shaping networks effective during the up-ramp and intermediate stages of the voltage signal, and the down-ramp stage respectively. The outputs of the networks are combined and applied to the oscillator for driving the motor. The shaping networks are rendered effective in turn by AND-gates responsive to signals from the linear function generator. The system may be modified for digital control by employing a generator supplying pulses to the motor and which is associated with a controller receiving signals representing the actual position of the motor. In the controller, the instantaneous velocity is computed from the position signals and the optimum acceleration for that velocity is determined. Alternatively, a ramp shaping circuit in the controller provides an analogue generation of the ramp but the output to the pulse generator is in digital form.

An ironing press comprises a pair of parallel heated pressing plates 13, 21 and an inflatable envelope 10 of resilient material, e.g. rubber, which is adapted to the shape of the article to be pressed and contains support members 12 so that the envelope may be inserted in a deflated or partly inflated state into the article 1, an inner tube 11 supplying the medium for expanding the envelope which can be inserted between the pressing plates. The supporting member 12 pivots along the tube 11 and compressed air is supplied to 11 via cylinder 15 and a reversible control valve 17. The pressing plates 13, 21 are connected via levers 24 and pivots 25 to two oppositely acting pneumatically-operated pistons 27, 27<SP>1</SP> which actuate the movement of the pressing plates. Adjustable stops 34 lock the levers in the pressing position and adjustable stop screws 35 limit the stroke of the pistons. The tube 11 acts as a stand for the envelope and the apparatus may be arranged horizontally or vertically. For continuous operation a number of inflatable envelopes may be arranged on a common carriage or a rotary turntable so that several envelopes are loaded ready for pressing. For producing a high-pressing finish a solid or highly resilient cushion may be fitted inside the envelope, the cushion thickness corresponding to the opening between the pressing plates. In a further embodiment the article to be pressed is fitted over a partly inflated envelope which is then fully inflated after insertion between the pressing plates which remain stationary.

Abstract: 1,100,818. Random access stores. NATIONAL CASH REGISTER CO. 14 Sept., 1966 [18 Oct., 1965], No. 41068/66. Heading G4M. The access time of a card random access memory of the type disclosed in Specification 889,788 is reduced by providing continuously rotating rollers 44, 47 which engage the edges of a strip 12 released from magazine 22 and accelerate it towards the vacuum capstan. The difference between the peripheral speed of the capstan and the speed of the strip when it is engaged by the capstan is reduced, and this reduces the amount of whipping of the trailing edge of strips 12 which takes place. Whipping is further reduced by providing vacuum ports in the walls of the funnel-shaped chamber leading to the capstan and by providing resilient surfaces to these walls to absorb impact energy. The strips 12 have notches 61 so that strips in the magazine are not engaged by rollers 44, 47, but a selected strip is engaged after falling a very short distance. A strip engaged by rollers 44, 47 is slightly bowed to ensure that sufficient force is exerted on the rollers for the strip to be positively driven downwards.
