Abstract: 1,110,610. Blow-moulding machine. BAKER PERKINS GRANBULL Ltd. 6 Sept., 1965 [30 Sept., 1964], No. 39826/64. Heading B5A. A blow-moulding machine has an extrusion head, preferably with two extrusion nozzles, two stationary mould-holders for holding, opening and closing two two-part blow-moulds, both below and on opposite sides of the extrusion head, and gripping means, movable along an inclined plane to grip extruded tubing, and move it diagonally downwards to one mould and then to the other. Preferably, the gripping means comprises two separate grippers so that while one tubing is delivered to the mould by one gripper and blown therein, the other gripper is receiving further extruded tube. Each gripper preferably is carried on a mounting, movable along an inclined guide, which preferably comprises two parallel rods passing through openings in the mounting so that the mounting may slide along the rods, e.g. by means of a pneumatic ram. Each gripper may comprise two pairs of pivoted jaws, opened and closed by a pneumatic ram acting through a toggle. Each mould may have two cavities, and each gripper may therefore be such as to carry the two extruded tubings to the mould.

Abstract: 928,810. Centrifuges. GUTEHOFFNUNGSHUTTE STERKRADE A.G. Nov. 25, 1959 [Nov. 25, 1958], No. 40115/59. Class 46. A device for controlling the charging of a centrifuge, comprises switch means 18 for causing operation of a charge inlet valve (not shown), a shaft 6 rotatably mounted on a fixed part 1 of the centrifuge so as to extend downwardly into its drum 2, a switch operating member (e.g. a cam 8) secured to the upper end of the shaft 6, and a feeler arm 7 secured to the lower end of the shaft and extending substantially radially of the drum 2 when the charge 19 is below a predetermined thickness, an increase in the thickness causes the charge to contact and rotate the arm 7 and thereby cause rotation of the shaft 6 and movement of the cam 8 to cause the switch means 18 to close the inlet valve. An electromagnet 13, which is energisable by the centrifugal control switch gear (not shown), rotates the cam 8 by means of the cable 10 to a position shown in Fig. 1 in which the switch 18 causes the inlet valve to open and the feeler 7 to move to its operative position 15 degrees beyond a position which is radial relative to the drum 2. The member 8 is held in this position by the spring 15. When the layer 19 reaches a predetermined thickness it moves the feeler 7 in the opposite sense to rotate the cam 8 and allow the switch 18 to close the inlet valve. The spring 15 moves beyond the dead-centre and takes the feeler to a position limited by the stroke of the electromagnet 13. The switch operating member may be a simple dog which actuates a tumbler switch. Specification 928,809 is referred to.

Title: Plutonium extraction process
IPC: G21C19/46
Filed: 1959-12-02
Abstract: 880,919. Plutonium separation. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 2. 1959 [Jan. 27, 1959], No. 40894/59. Class 39(4) Plutonium is separated from fission product contaminants by forming an aqueous nitric acid solution containing plutonium in the +4 oxidation state and having an acidity of at least 7.0M, extracting the plutonium with a solution of an aliphatic secondary amine in tetrachloroethylene, xylene, refined mineral oil, kerosene. or a mixture of kerosene and decyl alcohol, and stripping plutonium from the organic phase with water slightly acidified with nitric acid. The preferred amine is a branched chain secondary amine of molecular weight 300-400. Spent plutonium reactor fuel may be dissolved in concentrated nitric acid, the solution filtered to remove ruthenium and molybdenum, and then extracted with an organic solvent to remove radioiodine. The solution is treated with sodium hydroxide to lower the acidity to about IN and then with hydroxylamine nitrate to reduce the plutonium to the +3 oxidation state; sodium nitrate is used to oxidise the plutonium to the +4 oxidation state and nitric acid added to raise the acidity to 7-9N. Extraction of the plutonium with the organic solvent may be carried out in a countercurrent extraction column and the organic phase is then stripped several times with slightly acidified water, the later stripping solutions containing hydroxylamine nitrate. Plutonium is precipitated as oxalate from the combined aqueous solution and the precipitate is converted to oxide which is dissolved in nitric have these voltages applied to elements of its surface so that there is produced on a viewing acid; plutonium is again precipitated as peroxide and converted to fluoxide which is reduced with calcium in the presence of iodine as described in U.S.A.
