Title: Process for the production of fibrous granulates
IPC: B01J2/12
Filed: 1973-07-06
Abstract: 1428853 Granulating SOC D'EXPLOITATION DES BREVETS GRANOFIBRE SEBREG 6 July 1973 [21 July 1972] 32435/73 Heading B5A [Also in Division D1] A method of manufacturing a fibrous granulate comprises agitating natural or synthetic fibres which are dry on their surface and have a moisture content of not more than 55% of the total weight of the fibres under dry conditions in order to initiate their imbrication in groups and form fibrous aggregates having little cohesion, depositing a liquid on the surface of the fibres of the aggregates to form liquid menisci between the surfaces of each aggregate and cause tightening of the fibres and evaporating the liquid to intensify the tightening. The fibres may be agitated in a tunnel rotating about a horizontal axis. The aggregates may be graded after agitation. The liquid may be deposited by atomization or spraying. The aggregates may be spread in a layer on a horizontal inclined, cylindrical or helical surface and vibrated during liquid deposition. The liquid may contain an agent which swells the fibres, softens the surface of the fibres or bonds the fibres together to improve further the connection between the fibres of an aggregate. The aggregates may be subjected to a heat treatment to produce either local welding between the fibres or contraction, if the fibres are thermocontractible. The moisture content after liquid deposition may be from 50- 80% as based on the total weight of the moist aggregate. The liquid may be water which may contain a surfactant and/or a binder such as starch or the liquid may be a hydrocarbon. Many inorganic and organic fibres are disclosed. The aggregates may be used as insulating fillers or as the base layer of laminates.

Title: Recovery of plutonium
IPC: G21C19/46
Filed: 1945-12-04
Abstract: 839,191. Separation of plutonium and neptunium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 4, 1945 [Nov. 30, 1944], No. 32815/45. Drawings to Specification. Class 39(4). Plutonium is separated from fission products by precipitating the plutonium in its higher oxidation state as an alkali metal plutonyl acetate. When the plutonium content of the solution treated is small, the corresponding uranyl salt may be precipitated at the same time, or added to the solution, and this salt acts as a carrier for the plutonium ; the fission products remain in solution. Plutonium and uranium may be separated by reducing the plutonium so that it does not precipitate and then precipitating the alkali metal uranyl acetate. A suitable oxidising agent is a dichromate and suitable reducing agents are sulphur dioxide, sodium bisulphite, hydroxylamine, or hydrogen peroxide. In examples, solutions of uranyl nitrate containing plutonium and fission products are treated as follows:- (1) the solution is oxidised with sodium dichromate, and sodium acetate added to precipitate uranium and plutonium ; the precipitate is washed, dissolved in nitric acid, the solution reduced with sodium bisulphite, and uranium precipitated by adding sodium acetate, leaving plutonium in solution ; (2) the solution is reduced with hydroxylamine hydrochloride, and sodium acetate is then added to precipitate uranium; the filtrate containing plutonium and fission products is oxidised with sodium dichromate, a small amount of uranyl nitrate added and uranium and plutonium precipitated by treatment with sodium nitrate and sodium acetate ; the precipitate is removed, redissolved, and the process repeated; finally the plutonium may be precipitated as the complex acetate without uranium or alternatively may be recovered by evaporating the solution of reduced plutonium or by precipitating as phosphate or fluoride; (3) as in Example (1) except that hydroxylamine hydrochloride is used as reducing agent. Plutonium and neptunium are separated from one another by dissolving irradiated uranium in nitric acid, reducing plutonium and neptunium with sulphur dioxide, adding potassium bromate to oxidise neptunium but not plutonium, and precipitating sodium uranyl acetate, neptunium being carried down, leaving plutonium in solution.
