Title: Solvent extraction of metals
IPC: C22B3/26
Filed: 1961-09-07
Abstract: <PICT:0986674/C1/1> <PICT:0986674/C1/2> In a process for the solvent extraction of metals wherein metals present in a pregnant liquid are extracted into a receptive liquid immiscible with the pregnant liquid, the two liquids are contacted to produce a mixture of extract and raffinate phases which are caused to separate out by subjecting the mixture to one or more high-voltage unidirectional electric fields established with a metallic treating vessel.  As shown in Fig. 1, ore is treated at 7 with a leaching agent entering at 8 and the resultant liquor counterflows a stream of receptive liquid from a line 11 in a number of mixer-settlers 12.  The resulting mixture is then pumped through a mixer 18, a by-passable de-entrainment tank 19, a mixer 22 and a heat-exchanger 23 to an electric treater 25, wherein the mixture is separated into extract and raffinate phases.  The extract phase leaves the top of the treater and flows through a wash column 28, an extraction column 30 and a recovery system 34 which discharges the metal in pure or chemically combined form at 35.  To reduce the conductivity of the mixture for the electrical treatment, some of the extract phase may be recycled from the top of the treater 25 to the heat exchanger 23, and some or all of the more conductive liquid at the bottom of the treater 25 may be recycled to the mixer 18.  Additionally the tank 19, and a preliminary treating zone 54, Fig. 2, of the treater 25 may be used for gravitational separation of the more conductive phase liquid.  The receptive liquid may comprise kerosene or hexane containing a chemical such as alkyl carbitols, alkyl esters or alkyl ketones having a selective affinity for the metal to be extracted. Alternatively the solvent may comprise bis (disubstituted-phosphinyl) methanes of the general type R2 P (O) CH2 (O) PR2, for example bis (di-n-hexylphosphinyl) methane.  The Specification describes a specific example of the process as used for the extraction of Uranium U3O8 from an ore concentrate containing 20-30% impurities wherein the ore concentrate is digested with a 1 M nitric acid solution and counterflowed in the mixer-settlers 12 with 30/70% solution of tributyl phosphate in hexane.

Title: Improvements in or relating to re-heaters for steam turbine installations
IPC: F01K7/22
Filed: 1919-12-22
Abstract: 160,902. Merz & McLellan, and Bowerbank, A. W. Dec. 22, 1919. Controlling superheat.-Relates to means for regulating the heat supplied to the inter-stage reheater of a multi-stage steam turbine in accordance with the amount of steam passing through it. A piston 41, Fig. 3, subjected on one side to the pressure of a spring 44, and on the other side to the pressure of steam tapped from a suitable point of the turbine, is adapted to actuate a sliding member 35 having cam projections 37 which engage successively rollers 34 on the stems of valves controlling the supply of fluid fuel to the burners 25 of the reheating chamber 10. The air supply to each burner may be controlled in a similar manner by a device connected to the rod 45. The hot gases from the burner 25 flow past a feed water heater 30, round the baffles 15 and over the banks of tubes 13, 14 in the reheater, and are then conducted by a trunk 16 to vertical tubes 17 from the lower ends of which they escape to an outlet flue. Steam from the high-pressure stage of the turbines is conducted by a pipe 7 to the banks of tubes 14, 13 and thence by a pipe 9 to the low-pressure stage. The tubes 17 are used to heat the air supplied to the burners. If the turbine drives an electrical generator the fuelsupply regulator may be operated by an electromagnet device controlled by the load on the turbines.

Patent GB-1093134-A (GB)
Title: Nuclear reactor
IPC: G21C3/34
Filed: 1965-07-28
Abstract: 1,093,134. Fuel elements. GESELLSCHAFT FUER KERNFORSCHUNG m.b.H. July 28, 1965 [Aug. 1, 1964], No. 32226/65. Heading G6C. A cluster-type fuel element with spacers arranged at various levels between the fuel rods and attached to the can of at least one of the adjacent fuel rods has the fuel rods uniformly distributed but containing different mixtures of fissile and fertile material, the spacers being connected only with those fuel rods containing a relatively high percentage of fertile material. In one such element, as shown in Fig. 1, the fuel rods 1, 2 are assembled in a square basic lattice and surrounded by a can 4. The fuel rods 1, which contain a relatively high proportion of fertile material, are located at the intersections of a second lattice of twice the spacing of the basic lattice and have groups of four tubular spacers 3 attached at various points along their length. Longitudinal fins 5 or further tubular spacers 6 space the outermost fuel rods 2 from the can 4. In order to minimize the flow resistance of the spacers, they may be chamfered at their ends to give a trapezoidal longitudinal cross-section and joined by their longest sides to the fuel rods 1 (Fig. 3, not shown). Since their lines of contact with the fuel rods 2 are relatively short, this arrangement results in less disturbance of the heat removal from the highly loaded surfaces of the rods 2. The chamfered ends reduce the surface area contacted by the coolant resulting in a reduced flow resistance. Alternatively (Fig. 4, not shown), the walls of the tubular spacers taper to a point so as to minimize flow resistance and bulges on the outer walls of the spacers make point contact with the adjacent fuel rods 2. In the arrangement of the fuel rods shown in Fig. 5, fertile rods 11 bearing spacers 13 extend only throughout the core proper 14 of the reactor while the ends of the fissile rods 12 are connected to fertile rods 15 of large diameter. The diameter of the rods 15 may be such that they contact one another. Because there are no rods 11 in the blanket regions of the reactor, the coolant flow cross-sections at the inlet and outlet are still sufficient, even in this extreme case. The rods 12 have connections with the rods 15 which are permeable to gas and thus the large quantities of fission gases generated in the rods 12 are able to flow into the rods 15. Additional gas storage containers may be connected to the rods 15. It is possible to use other spacers of different shapes to those described, e.g. spacers made of sheet metal strips.
