IPC: B01D59/20
Filed: 1968-10-25
Abstract: 1,212,449. Centrifugal separators. DORYOKURO KAKUNENRYO KAIMATSU JIGYODAN. 25 Oct., 1968 [26 Oct., 1967], No. 50846/68. Heading B2P. A gas centrifuge for separating uranium-235 from other isotopes in natural uranium hexafluoride comprises a rotor 20 rotatably mounted in a casing 10 and having a hollow upper supporting shaft 23, through which a mixture of uranium hexafluoride and helium gas is fed to the rotor and a hollow lower supporting shaft 24 through which separated helium gas is removed from a central region of the rotor, the end plates 21, 22 of the rotor being provided with holes 25, 26 through which gas depleted in uranium-235 and gas enriched in uranium- 235 are respectively ejected into chambers A and B from which they are swept through extraction pipes 13, 14 by means of the helium gas removed through the hollow shaft 24 and tangentially introduced, through nozzles 12 at the end of feed pipes 11, into the annular space 50 between the rotor and the casing whence the helium gas flows into the chambers A, B via annular clearances 31, 32 between the end plates of the rotor and flange-shaped projecting parts 27, 28 of the casing. The ratio of helium gas to uranium hexafluoride varies from 1:1 to 3:1. The amounts of gas enriched and depleted in uranium-235 ejected from the rotor are equal and equal amounts of separated helium gas are fed to the chambers A, B. The gas mixture in the rotor is subjected to pressure diffusion by means of rotation of the rotor at a high velocity and to counter-current flow by means of a heating device 41 and a cooling device 42. The helium gas removed from the rotor may be purified in a centrifuge before it is fed to the space 50. A valve 19 in one of the feed pipes 11 ensures that the helium gas fed to the rotor is the same as that fed to the space 50. Vacuum. pumps are connected to the extraction pipes 13, 14. In carrying out an enrichment process a number of centrifuges are arranged in a cascade formation, Fig. 3 (not shown), comprising a central supply step, a number of enrichment steps for enrichment of the uranium hexafluoride in uranium-235 and a number of recovery steps for depleting uranium hexafluoride from uranium-235. The enriched gas mixed with helium gas is fed to a rotor performing the next step in the enrichment process while the depleted gas mixed with helium gas if fed back to another rotor performing the previous step.

Title: Magnetic reed proximity detector
Inventor: SMITH WILLIS RAYMOND
IPC: B61L1/08
Filed: 1969-10-17
Abstract: 1,249,043. Track apparatus. GENERAL SIGNAL CORP. 17 Oct., 1969 [30 Oct., 1968], No. 51105/69. Heading B7N. [Also in Division H1] A magnetic proximity detector has a polarized reed relay arranged so that flux is diverted due to the approach of a magnetic mass to permit contact operation to effect energization of the relay coil to reset the contacts so that the coil is de-energized. So long as the magnetic mass is in the vicinity of the relay its contacts will continue to open and close. As shown the encapsulated relay 5, which may be mounted on an insulating support 22 on a rail for operation by a railway wheel flange, has a sealed reed contact unit 7 surrounded by the coil 6 and spaced a set distance from a permanent magnet PM. The flux from the permanent magnet is insufficient for contact closure but sufficient to hold the contacts closed and on approach of a magnetic mass such as a wheel flange the contacts open to de-energize a relay A which has contacts sets 10, 11. When relay A is deenergized its contacts 10 close to energize the coil 6 which recloses contacts 7 to de-energize relay A to open contacts 10 which disconnect the coil 6 so that contacts 7 reopen if the magnetic mass is still present and so the relay A is continuously opened and closed until the mass is moved away. The contacts 11 operate when relay A is de-energized and disconnect a relay B which will not reset whilst the relay A oscillates since a capacitor 17 does not recharge sufficiently during the intermittent reclosures of contacts 11. A set of contacts 14 of the relay B connect the supply to the coil 6 through a resistor 15 so that the distance from the switch 5 at which the magnetic mass effects initial operation thereof is reduced.

Title: Method for carrying out gas-solids reactions
IPC: C22B1/10
Filed: 1965-12-02
Abstract: 1,135,753. Fluidized bed reductions. PULLMAN Inc. 2 Dec., 1965 [7 Dec., 1964], No. 51301/65. Heading C1A. [Also in Divisions B1 and C7] Metal oxides, e.g. ores, are reduced in a reaction zone containing at least two fluidized beds separated by vertical baffles, the spaces above the beds being intercommunicating. The ore is preferably an iron ore, e.g. haematite, siderite, or limonite, which is reduced to magnetite. In Fig. 1, reactor 140 contains fluidized beds 142 and 144, preferably maintained at 800-1400‹ F., separated by arc-shaped baffle 138. Ore is fed from line 130 into bed 142, passes through orifice 146 into bed 144, is removed via line 150, and may be passed to another bed for further reduction. Beds 142 and 144 are fed with gases from partial oxidation furnaces 160 and 170 respectively, and with recycle gases from line 66. The gases may be of equal reducing strength, having a composition such that over-reduction beyond Fe 3 O 4  cannot occur. Alternatively, as described in Specification 1,135,755, the first gas may have a composition such that reduction beyond Fe 3 O 4  does occur, and the second gas may be oxidizing with respect to FeO and has a composition such that oxidation beyond Fe 3 O 4  cannot occur. The positioning of the baffle, which may be such as to give 65-80% conversion to Fe 3 O 4  in bed 142, reduces the total solids residence time necessary to achieve, e.g. 90% conversion, to below 90 mins. The ore is preheated (as described in Specification 1,135,754) first in cyclones 18 and 12, and then in fluidized bed heating zone 110 or in transfer line heat-exchanger 210 (Fig. 2, not shown), effluents from zone 110 and reactor 140 being recycled to cyclone 12. Alternatively, only the effluent from 140 may be used, or the effluents from beds 142 and 144 may be recycled separately.

Abstract: 1,111,569. Multiple effect evaporators; distillation of water. BURNETT & ROLFE Ltd. 20 Dec., 1965 [30 Dec., 1964], No. 52848/64. Heading B1B. Liquid, e.g. sea water, is distilled in a multiple effect evaporator comprising a series of metal plates 1 arranged face to face with spaces between them forming a series of cells 2, the whole series being disposed between a steam chest 23 and a condenser chamber 26. The cells are maintained under reduced pressure by pump 39. Sea water supplied through pipe 13, is distributed through pipes 11 and slots (not shown) so that it flows as a film down the right-hand side of each plate 1. The left-hand side of the first plate is heated by steam chest 23, and the vapour given off from the waterfilm on the other side of the plate flows across the cell 2 and condenses on the opposite plate and thus supplies heat through this second plate to the water-film flowing down its righthand side in the second cell. This same process of evaporation and condensation takes place in the following cells, but in the last cell the vapour condenses on the plate bounding the condenser chamber 26. The bottom of each cell is divided into two adjacent troughs by a vertical plate (not shown). Unevaporated water is withdrawn from the left-hand troughs through pipes 15 which lead to a common pipe 20. Distilled water is withdrawn from the righthand troughs through pipes 17 which lead to a common pipe 22. The unevaporated water and the distillate are withdrawn from the system via pipes 43 and 44, respectively, which pass through heat exchanger 38. The sea water to be distilled is pumped through heat exchanger 38, and is thereby preheated before it reaches to tops of plates 1. The distillation of ethyl alcohol, acetone and toluene is referred to. The recovery of butyl acetate from water is mentioned.
