Patent GB-771679-A (GB)
Title: Electrolytic production of titanium and zirconium
IPC: C25C3/26
Filed: 1954-01-18
Abstract: In the electrodeposition of titanium and zirconium (with or without the naturally occurring small percentage of hafnium) by electrolysis of an alkali metal-titanium or -zirconium double fluoride dissolved in a fused alkali metal chloride, the evolved chlorine and the spent electrolyte containing alkali metal fluorides are reacted externally of the cell with a chlorinatable titanium or zirconium compound containing in its anion only one or more of the elements chlorine, oxygen, or carbon, or the elements oxygen, carbon and nitrogen in combination to form the said double fluoride and alkali metal chloride by heating in the presence of a reducing agent, the said product being returned to the cell.  Either the evolved chlorine is reacted in the presence of a carbonaceous reducing agent, such as a hydrocarbon, carbon monoxide or preferably carbon, with a chlorinatable compound, typically the dioxide, of titanium or zirconium, and the resulting chloride, typically the tetrachloride, is then separately reacted with the spent electrolyte; or it is reacted with hydrogen or propane and steam to form hydrogen chloride which is reacted with the titaniferous or zirconiferous compound in the presence of the spent electrolyte.  Preferably the reactions are effected in the presence of water heated to near the boiling point. Losses of fluoride and chloride from the cell as by drag-out are made good by the addition to the reactor of potassium chloride and hydrofluoric acid.  Either the spent electrolyte after cooling is fed directly to the reactor or preferably it is broken and formed into a water slurry.  The aqueous solution of the double fluoride and chloride, typically of potassium and sodium respectively, is then delivered to the third effect of a triple effect evaporator which concentrates the solution to effect crystallization of the double fluoride from the effluent which is then delivered for further concentration to the second and first effects from which the chloride is obtained, and after drying the double fluoride and chloride are returned to the electrolytic cell.  Electrolysis is performed under an argon atmosphere which is removed with the chlorine and is recovered from the chloride-forming stage and finally after purification returned to the cell.  Specification 713,446 [Group XXXVI] is referred to.

Patent GB-482478-A (GB)
Title: Improved mechanism for spooling or reeling wire
IPC: B21C47/00
Filed: 1937-01-20
Abstract: 482,478. Winding wire. ELEVATOR SUPPLIES CO., Inc. Jan. 20, 1937, No. 1732. Convention date, Jan. 28, 1936. [Class 120 (ii)] In a machine for spooling or winding wire in which the spool spindle is driven at a progressively diminishing speed as the radius of the wire on the spool increases with successive layers, the spindle is driven through a variable speed gear which is adjusted by means comprising a member successively displaced from the axis of the spindle through contacts with successive layers of wire as they are wound and return movement of the displaceable member towards the spindle is prevented so that it cannot move towards the axis of the spindle to follow any irregularities of the wound wire with respect to the axis of the spindle ; the displaceable member may directly or indirectly actuate the speed gear and may be moved directly or indirectly by the wire on the spool. As shown the wire from a drawing apparatus 10 passes over a tension pulley 210, through a traverse device 115 to the spool S on the spindle 18 which is driven from the shaft 20 by a belt 39 and expanding V-pulley 41, the movable plate 42 of which is fixed to a sleeve 44 slidable on the spindle 18 and having a threaded part engaging a fixed nut 45. The wire on the spool is engaged by a roller 120 at the end of an arm 50 fixed to a shaft 52 carrying a toothed sector 54 engaging a gear 55 on the sleeve 44 so that as the arm 50 moves away from the spindle 18, as each fresh layer of wire is'wound on the spool, the plate 42 of the V-pulley is moved towards the fixed plate thereof to cause a reduction in the speed of the spindle and give a substantially constant peripheral-speed to the wire being wound on the spool. Return movement of the arm 50 towards the spindle is prevented by means of a pawl 64, carried by an arm 60 on the shaft 52, engaging a fixed toothed sector 66; the pawl may be made with a number of teeth so that any return movement is limited to a fraction of the length of a tooth of the sector 66. In a modification the arm 50 carries a pivoted finger which contacts with the wire and carries one member of a make-andbreak device in circuit with a solenoid, the finger moving to break the circuit when a fresh layer is started and cause movement of the solenoid which then actuates a pawl engaging a ratchet on the shaft 52 ; rotation of the shaft moves the sleeve 44 and also the arm 50 with the pivoted finger away from the spindle 18. In a further modification, the arm 50 is mounted on a separate shaft, movement of the pivoted finger causing actuation of the ratchet and consequently of the sleeve 44 which also causes a cam engaging an arm on the shaft carrying the arm 50 to move the arm from the spindle 18.

The valves E controlling the auxiliary blasts are actuated by cams 27 on the reversing shaft G of the reciprocator valve gear. These cams actuate push rods 22 through links 25 which are pivoted and co-operate with stops 30 so that the cams are effective only in one direction of operation of the shaft G. In emergency the valves E may be rendered inoperative by hand lever 35 which rocks a lever 33 so as to displace the link 25.
Patent GB-578700-A (GB)
Title: Improvements in or relating to variable-ratio drive or coupling mechanism
IPC: F16D67/00
Filed: 1944-01-31
Abstract: 578,700. Variable-speed gearing. CROSS, E. J. (Watson, S. C.). Jan. 31, 1944, No. 1784. [Class 80 (ii)] A two-element hydraulic coupling 18, 32 is combined with an epicyclic train 21, 43, 51 having worm-type gearing, a one-way brake being provided to prevent reverse rotation of the runner of the coupling. Another train 99, 91, 67, is provided in series so that slip in the coupling produces a double reduction of speed on the driven shaft 76. The driving shaft 1 carries the impeller 18 of the hydraulic coupling and also the sun gear 21 of the first epicyclic train. The runner 32 of the coupling is connected through a sleeve member 25 to the planet carrier 41 of the first train which is in turn connected to the annulus 67 of the second train. The annulus 51 of the first train is connected to sun 99 of the second through casing 49 and sleeve 98 whilst the planet carrier of the second train is integral with the driven shaft 76. Reverse rotation of the runner 32 of the coupling, the planet carrier 41 and the annulus 67 is prevented by a one-way brake 110. In operation for light loads no slip in the coupling occurs and both trains rotate solid for direct drive. On increase 'of load the runner of the coupling slips and the speed of the annulus 51 of the first train is reduced through planetary action-so that a reduced speed is imparted to both sun and annulus of the second train giving a double reduction of the driven carrier and shaft 76. In the extreme case of a very heavy load the runner is stopped and held against backward rotation by the one-way brake, as is also the carrier 41 and annulus 67. The annulus 51 is driven through the worm planets at a reduced speed in the same direction of rotation as sun 21 to drive the shaft 76 at a very reduced speed through sun 99.
