Abstract: A glove box with tubular lines for harmful fluids and with shutoff valves inserted in the tubular lines and, respectively, formed of an actuating member and a valve body includes an exterior wall forming part of the glove box, the shutoff valves being disposed adjacent one another on the wall, the valve bodies of the shutoff valves being located on the inside of the exterior wall, and the actuating members of the valve bodies being located on the outside of the exterior wall; and a drive for driving the actuating members also located on the outside of the exterior wall and having a device for docking with the respective actuating members, the drive means being guidably displaceable in a plane parallel to said exterior wall to the respective actuating members for docking with the respective actuating members.

Abstract: A method for manufacturing Pu.sub.2 -containing crystals by oxidizing plutonium in a heavily contaminated nitric acid starting solution to Pu.sup.6+, precipitating ammonium plutonyl carbonate containing crystals by reaction with ammonium- and carbonate ions and subsequent separating and calcining of these crystals. The nitric acid solution with the oxidized Pu.sup.6+ as well as carbonate and/or acetate ions and NH.sub.3 are dosed into an aqueous starting solution of ammonium carbonate or ammonium acetate in a concentration such that the mol ratio of carbonate and/or acetate ions to the Pu.sup.6+ -ions in the solution is at least 4:1 and plutonium containing carbonato- or acetato complex compounds which remain dissolved in the receiver solution, are formed, while difficult-to-dissolve metal hydroxide compounds are precipitated. Thereupon NH.sub.3 and carbonate ions are added to precipitate the ammonium plutonyl carbonate containing crystals.

Abstract: Purifying a nitric acid solution containing U/Pu ions and contaminated by metal impurities by(a) oxidizing the U/Pu ions of the solution to the hexavalent form,(b) conducting the solution after oxidation through a cation exchanger column in which the impurities, especially americium, are retained,(c) flushing the cation exchanger column to remove impurities therefrom, which may be taken to waste processing or utilization plant.

Abstract: The cable is made by cascaded SZ pattern stranding of elements (individual conductors, or bundles) in a first stranding level by means of multiple units each having a stationary aperture disk, a reversably revolving aperture disk, a tube between them, and a stranding head downstream from the revolving disk, with a wrapping station between them, resulting in plural, stranded bundles serving as stranding elements in a further unit for second-level stranding and being basically similarly constructed as each of the first-mentioned units.

Abstract: Manufacture of uranium/plutonium oxide mixed crystals soluble in nitric acid in which a solution of uranium nitrate and plutonium nitrate are oxidized to cause the plutonium to reach valence VI. The oxidized solution is admixed with ammonium carbonate, oxalate or carbamate and the pH adjusted to 8.1 to 8.5 to precipitate an ammonium uranyl plutonyl carbonate, oxalate or carbamate. The precipitate is calcined to uranium/plutonium oxide.
