Title: Improvements in or relating to the recovery of uranium
Inventor: THOMAS THOMAS GARFIELD
IPC: C22B60/02
Filed: 1958-02-17
Abstract: Residual uranium values are recovered from calcium and magnesium fluoride slags, arising from the production of uranium from uranium tetrafluoride by treatment thereof with calcium or magnesium, by leaching the fluoride slag in stainless steel equipment with nitric acid at 40 to 80 DEG C., so that the final acidity is between 1/2 and 5-normal.  The uranium is brought into the aqueous solution which may then be treated with an organic solvent to recover the uranium selectively.  According to an example, a magnesium fluoride slag was finely ground and leached with 60% nitric acid at 60 DEG C.; the final acidity is 1 1/2 normal.  The leach may be effected in a vessel made of austenitic stainless steel containing 18% chromium, 8% nickel and 1% titanium.  The acidity of the leach may be adjusted if required by the addition of lime or other base.  The leach slurry is then filtered and the solids washed.  Alternatively the leached slurry may be treated with a flocculating agent and separated by simple decantation.  The filtrate may then be treated with 20% solution of tributyl phosphate in kerosene to extract the uranium.

Filed: 1969-01-31
Abstract: 1,263,971. Filling blow-moulded bottles; checking. M. UCHIDA. 31 Jan., 1969 [1 Feb., 1968; 3 Feb., 1968; 8 Feb., 1968], No. 5319/69. Heading B5A. [Also in Division G1] Charged plastics bottles are produced by blow-moulding the bottle from thermoplastic resin, checking the presence or absence of holes, cracks &c. by means of air pressure while in the mould, filling the bottle if free of defects and sealing the bottle while in the mould sections. Compressed air may be fed into the bottle to establish a predetermined air pressure in it, departures from the predetermined pressure being registered by a pressure gauge which interrupts production if necessary. Alternatively, a subatmospheric pressure may be drawn between the bottle and the mould wall. The bottle may be moulded by extrusion-blow moulding or by injection-blow moulding. As shown in Fig. 1, an extruder 3 may be used having a screw I in barrel 2 having five accumulator passages 5 with a valve 18 and mandrel 21 in each of five extrusion passages. The accumulators have plungers 7 fixed to rods 17 and block 15 which is reciprocated on guide rods 9 by cylinder 12. Nuts 16 on rods 17 limit plunger movement by abutment on stop blocks 6, 8. Valve 18 comprises a rod passing through each extrusion passage having diametral bores. The mould with the parison therein is then passed to the blowing station (Fig. 5, not shown) where blowing nozzle (25) expands it to form the bottle. Alternatively, the parison may be injection-moulded as shown in Fig. 9. The parison 37 is formed on a core 36 mounted on extendable shaft 38 of rotary assembly 39, 40, between injection mould halves 35, 35<SP>1</SP> by nozzle 34. One parison is formed by injection while the other is being blown in blow-mould halves 45, 45<SP>1</SP> After checking, the bottle is filled from nozzle (65, Fig. 19, not shown), sealed with cap (68, Fig. 20, not shown) by means of sealing stamp (67) and the filled, sealed bottle (69, Fig. 21, not shown) deposited on belt conveyer (70) after opening of mould halves (59, 59<SP>1</SP>).

Title: Improvements in or relating to rectifier arrangements
IPC: B60L9/12
Filed: 1952-02-29
Abstract: 715,090. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd., FRIEDLANDER, E. S., and GALLIZIA, E. Feb. 9, 1953 [Feb. 29, 1952], No. 5389/52. Class 38(3) [Also in Group XXXV] A D.C. motor control system comprises a direct current motor fed from an alternating current source over a full wave rectifier arrangement wherein the rectifier elements are connected to tappings on a transformer winding and one of the D.C. terminals is formed by a tapping on a compensating reactor which is connected to tappings intermediate the ends of the transformer winding. As shown a direct current series wound motor 57 is supplied from a secondary winding I of a transformer over gas discharge vessels 31 ... 34 operating in parallel pairs. The tapping 21 ... 25 on one side of the imaginary zero point 20 of the winding 11 are different from and intermediate in potential to those 26 ... 30 on the other side of the point 20. Each tapping point is taken to two contactors arranged in two groups. To start the motor the tapping 21 is connected to the anodes of the vessels 31, 32 by closing the requisite contactor in the group 41 and 42; and at the same time connecting the tapping 26 to the vessels 33, 34 by closing the requisite contactors in group 43, 44. Since the tappings 21, 26 are at different, potentials the direct current windings 53, 54 on the self balancing reactor will operate to counteract the differences in potential by causing the mid-point of the alternating current windings 52 or the reactor-which are connected betwen two equi-potential tappings on the winding 11-to assume a potential which is midway between the potentials of the tappings 21. 26, thus a certain potential exists across the motor. To change this potential the contactor of the group 41 is opened and the second contactor in that groun is closed, the vessel 31 now being at a different potential to that of the vessel 32; this unbalance is however mitigated by a reactor 62. A different value of potential now exists across the motor and this operation may be repeated by opening and closing the various contactors in the groups 41 ... 45, either in sequence or alternately. During opening and closing of the contactors the respective vessels 31 ... 34 are rendered non-conductive by the application of a blocking potential to their grids from a rectifier bridge 50. Instead of being of the self-balancing type the reactor 52 may have a number of tappings thereon, the required point of mid-potential being choosen manually. A number of such arrangements may form a polyphase system.
