Abstract: 1,196,316. Planing; rotary tool head; welding by pressure; making wire; rolling. TEXAS INSTRUMENTS Inc. 31 Aug., 1967 [4 Jan., 1967], No. 39913/67. Headings B3A, B3L, B3M, B3R and B3T. Apparatus for drawing a wire 13 through a lubricated die 9, removing a contaminated surface of the wire and then cladding it with strip material 57, e.g. cladding copper strips on aluminium wire, by rolls 63 which squeeze and solid-phase bond the wire and strip together, comprises a rotating hollow cutter 15, 27 and a fixed shaving die 49 for removing the said surface of the wire. The rotating cutter is formed by a pulley 19 driven sleeve 15 mounted on bearings 17, 25 and including cutters 27 radially adjustable by differential threading of screws 45, and the shaving die 49 includes a carbide or tool steel liner 51. The rotating cutter is adjustable axially so that the cutter and die 49 are closely adjacent, e.g. a .002 in gap between the relative cutting planes, so that a cutting action and chip breaking occur. The radial adjustment of the cutters 27 are set so that either (a) the cutters 27 just graze the surface of the wire and all material is removed by the die 49, the cutters 27 breaking up the chips therefrom, or (b) the cutters 27 remove all the material and the die 49 just grazes the finished size of the wire and breaks up the chips formed by the cutters 27, or (c) both the cutters 27 and the die 49 remove material in successive stages. The strips 57 are fed to the rolls 63 via retorts 59 and passageways 60 and are held on to the grooved edge of the rolls 63 by spring loaded pads 61. The space in the retorts 59, passageways 60 and nip area 62 is supplied with a reducing gas, e.g. hydrogen, or an inert gas, e.g. argon, the cutting edge of the die 49 acting as a seal and seals 65 being arranged on the end faces of the rolls 63. The rolls squeeze and reduce the size of the clad wire and a rib 58 may be formed which is subsequently removed.

In apparatus for separating sheets sequentially from the top of a pile. a pile of printed and interleaving sheets is lifted by means of chain-operated elevators (2, 3, Fig. 1), until the topmost sheet is adjacent two pneumatic lifting rods 4 and 5 arranged on opposite sides of the pile. The surface of the topmost sheet is scanned by photo-electric cells 6 and 7, and the suction to one of the lifting rods is controlled according to whether the topmost sheet is a printed or interleaving sheet. Two springs 8 which engage into lateral recesses of the interleaving sheet on the side towards which the same is pulled off, prevent a printed sheet from being lifted at the same time. Pile tables.-The chain elevators (2 and 3, Fig. 1) are independently driven by separate motors, and each motor is controlled by a scanner 9 and 10 respectively, so that level gaps between the stack edges and the suction rods can be accurately maintained.

Title: Improvements in or relating to the processing of metal fluorides
Inventor: GRANT ALBERT EDGAR
IPC: C01G43/06
Filed: 1964-10-05
Abstract: Uranium is separated as the hexafluoride or the oxyfluoride from a mixture of metal fluorides, e.g. that produced by the fluorination of a uraniferous ore or an irradiated fuel element, by bringing the mixture into contact with anhydrous liquid HF so as to dissolve at least some of the uranium hexafluoride, separating the undissolved material and treating the solution so obtained to recover the uranium. The uranium is either obtained from the solution as the fluoride by recrystallization or distillation or water may be added to the solution and the uranium precipitated as the oxyfluoride.  In treating the fluoride vapours obtained by fluorinating an irradiated fuel element, the vapours are passed into anhydrous HF near its boiling point, when the UF6, PuF6 and other soluble fluorides dissolve, and the less soluble fluorides e.g. CeF3, and ZrF4 are precipitated.  The precipitate is separated by filtration or decantation and the solution is distilled and the vapours cooled to precipitate UF6 crystals.  The other fluorides may be obtained by cooling the boiler residues.

[Also in Division H1] Apparatus for measuring the methane concentration of an atmosphere comprises two thermocouples covered with catalysts which react differently on an oxygen-methanol reaction in the presence of methane, whereby the difference in temperature is indicative of the methane concentration. As shown (Fig. 1), a tank 10 carrying liquid methanol 11 is fitted with a wick 12 enabling methanol vapour to be carried by the external atmospheric gas, which enters the housing 1 by apertures 9 and leaves by apertures 8, up through a chimney 5 to two thermocouples 14, 15 coated with different catalytic materials, each of which causes the methanol vapour to react with the atmospheric oxygen to raise the temperature of the thermocouples. The catalyst on thermocouple 14 enables methane in the atmosphere to enhance the oxygen-methanol reaction and its temperature is raised still further: the catalyst or thermocouple 15 is such that a methane atmosphere restricts this reaction, and its temperature is lowered. Thus, a meter 13 indicating the difference in thermocouple outputs may be calibrated in terms of percentage methane content in the surrounding atmosphere. An alternative construction is described Fig.5 (not shown).
