Abstract: 1,036,661. Centrifuges. VEB ZENTRALE ENTWICKLUNG UND KONSTRUKTION (ZEK) DIESELMOTOREN ROSSLAU. Feb. 26, 1964, No. 8065/64. Heading B2P. In a centrifugal oil separator comprising a drum 5 rotated in a housing 1, 3 by the reaction of cleaned oil discharging from one or more nozzles 8, the oil, before its admission into the separating chamber 11 of the drum, has imparted to it the angular velocity of the drum and is split into several streams by its passage through chamber 13 formed between ribs 12 arranged between the upper part of the drum and a plate-like member. The chambers 13 open into the chamber 11 through openings 14 Fig. 1, in the vicinity of the inner periphery of the drum, or through openings 18, Fig. 3. The ribs 12 may extend beyond the periphery of the plate-like member. The oil to be cleaned is fed at 2, 4. The purified oil passes through an axially-arranged opening 15 (which may alternatively face the inlet 4) into a pipe or channel 16 connecting the nozzles. Alternatively, the purified oil passes through a number of pipes individually connected to corresponding nozzles, the opening in each pipe being disposed in the vicinity of the axis of rotation of the drum.

Title: Improvements in or relating to the separation of plutonium
Inventor: MADDOCK ALFRED GAVIN
IPC: C22B60/04
Filed: 1947-03-26
Abstract: Plutonium in a valency state not higher than quadrivalent is separated from uranium by applying an aqueous solution containing plutonium and uranium to a metal fluoride which is substantially insoluble in water and has the property of adsorbing or chemisorbing the plutonium, and subsequently recovering the plutonium from the adsorbent by treatment with an aqueous inorganic nitrate solution. The adsorbent may be calcium, lanthanum, or other rare earth fluoride, and is preferably sintered, heat treated, or aged; alternatively calcium or lanthanum fluoride may be precipitated in the solution, carrying down the plutonium.  Suitable nitrate solutions are of aluminium, ferric, or manganous nitrate; the concentration of the solution may be 50 per cent or more of saturation.  Plutonium may be recovered from the nitrate solution by saturating with calcium, zinc, ammonium, ferric, aluminium, or copper nitrate, followed by extraction with a water-immiscible organic solvent, e.g. nitromethane, diethyl ether, or methyl isobutyl ketone. In examples: (1) an oxidized nitrate solution containing uranium, fission products, and plutonium is passed through a column of sintered calcium fluoride to remove fission products; the effluent solution is reduced with sulphur dioxide and passed through a similar column to adsorb plutonium which is removed by treatment with ferric nitrate solution, followed by extraction with nitromethane; (2) lanthanum nitrate is added to a solution containing uranium and tervalent or quadrivalent plutonium; hydrogen fluoride is then added to precipitate lanthanum and plutonium as fluorides and the precipitate is treated with ferric nitrate solution as in Example 1. Specification 783,601 is referred to.

Title: Method of forming filaments and filament products formed thereby

Abstract: 1,105,381. Making filaments. ROEHR PRODUCTS CO. Inc. 2 March, 1965 [2 March, 1964], No. 8850/65. Heading B3A. A method of forming filaments includes the steps of sheathing each of a plurality of elongated elements from which the filaments are to be formed with a material having physical characteristics differing from those of the elements to permit separation of the sheath material from the elements when desired; bundling the sheathed elements in parallel relationship; hot forming the bundle to reduce the cross-section thereof; drawing the formed bundle to reduce the cross-section of the elements therein to a preselected filament cross-section; and removing the sheathing material. As described, stainless steel wires are sheathed with copper or monel metal, a bundle of the sheathed wires are assembled in a cylindrical housing which is then evacuated and sealed and compacted, e.g. by compression or extrusion to form a billet. The billet is then hot-formed by extrusion or rolling and is then cold-drawn to the required cross-section. The material of the housing and sheathing is then removed, e.g. by immersion in nitric acid. Tubular filaments can be similarly made by providing tubular elements of stainless steel with cores and sheathing of copper or monel metal and repeating the above procedure.

[Class 39 (iii)] The supporting and current-supplying rods b of continuous self-baking electrodes are adjusted in turn as the electrode a is worn, by withdrawing each rod, introducing a quantity of electrode paste j into the hole and replacing the rod. The paste is rapidly baked, being in the hot baked portion of the electrode, and mechanical and electrical connection between the rod and the electrode is re-established. The rods are slightly tapered in their length and are somewhat sharpened at their ends b'. They are first loosened by turning before withdrawal. The self baking electrode may consist of carbon dust and pitch and is continuously filled up at the top inside the sheath d in operation. During the withdrawal of a rod it is preferably allowed to remain partly withdrawn for two hours so that the heat of the rod may bake the walls of the hole slightly to prevent crumbling.
