Abstract: 417,553. Leading-in wires for electric incandescent lamps &c. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Zabel, W. P. ; 2060, Hanover Road, Cleveland Heights, Ohio, U.S.A.) Jan. 5, 1934, No. 454. Convention date, Jan. 5, 1933. [Class 39 (ii).] In an electric incandescent lamp or similar device having a bulb with a filament sealed therein, with an inner leading-in wire in the bulb connected at one end to the filament, this latter end is in a soft annealed condition passive to oxidation. The leading-in wire assembly comprises the inner leading-in wire 16, Fig. 1, of nickel or an alloy thereof, such as manganese nickel, which is connected to one end of a short wire 19 of a metal having the same coefficient of expansion as the stem-press 17 into which it is adapted to be sealed, the other end of the wire 19 being connected to an outer leading-in wire 20 of copper. The end of the wire 16 that is to be connected to the filament 12 may be annealed by heating it by the passage of an electric current therethrough in an atmosphere of a non-oxidizing gas or in a vacuum, or by radiated or conducted heat from a muffle or electric tube furnace. In one method the leading-in wire assembly, comprising a nickel or nickel-alloy inner wire 16, press wire 19, and copper outer wire 20 are placed in a horizontal tube 24 with the free end of the wire 16 projecting about an inch beyond the end of the tube. A gas, preferably hydrogen, is passed through the tube 24 and ignited at the end thereof, so that the flame surrounds a portion of the exposed end of the wire. An additional hydrogen flame may be directed on the exposed end by a burner 26 located below it. The end of the wire is thus heated to a temperature above 700 C., approximately 1100 C. in the case of a nickel wire, the purification and annealing being effected in one or two minutes. After the heating is effected a sleeve 27 surrounding the tube 24 is slid forward beyond the end of the wire 16, after which the flames are extinguished but the flow of hydrogen through the tubes 24, 27 is continued in order to cool the hot end of the wire without oxidation. In the case of heavy leading-in wires the whole of the wire assembly may be annealed in an ordinary hydrogen annealing furnace at about 750-800 C. before the end of the inner wire is brought to the softannealed oxidation-resisting condition.

Title: Improvements in machines for rolling metal discs
IPC: B21H1/02
Filed: 1955-01-10
Abstract: 771,804. Rolling discs. WILKINS & MITCHELL, Ltd., and WILKTNS, E. W. Jan. 2, 1956 [Jan. 10, 1955], No. 667/55. Class 83 (4). In a machine for rolling metal discs as described in Specification 771,803, in which the work is indexed between rolls backed by platens and which reciprocate radially over its surface, the work-holder is in the form of a pair of clamping jaws 10, 11, Fig. 3, which may be swung downwardly and pivoted apart so that workpieces may be readily inserted and discharged over a pin 35. The jaws are mounted on a carriage 41 which is vertically adjustable relative to the rolls (not shown) along guides 42 of the machine frame, by a worm wheel operated screw 48. The jaws 10, 11 are pivoted on a horizontal shaft 38 and clamp the disc under the action of a pneumatic ram 39. For discharging or inserting the discs the jaws are turned to the horizontal position by a rack and pinion 43, 44, Fig. 4, which rotates the shaft 38. On approaching the horizontal the arm 11 is prevented from further movement by engagement of projecting arms 11<SP>x</SP> with fixed abutments 47 and clamping pressure in the ram 39 is automatically released so that the jaw 10 continues its downward movement and separates from the jaw 11. The indexing of the disc is obtained from intermittently rotated opposed friction rollers 37 mounted on shafts 49 in the jaws and urged against the disc by compression springs 53. The rotation of each shaft 49 is obtained from a rack 55 engaging a pinion 54 rotatable on the shaft and reciprocated between opposed pneumatic cylinders 58. The pinion 54 is coupled to the shaft through a ratchet drive and pneumatic clutch 61, 63 (not shown). The angle through which the disc is normally indexed is limited to 45 degrees by a second rack 56 moved by the pinion 54 and engaging stop pistons 59 in pneumatic cylinders 60 at each end of its stroke. After rotation through 315 degrees the index motion is limited to 22¢ degrees by actuating the right-hand piston 59 to limit the movement of the rack 56. The indexing then continues at 45 degrees so that the disc is rolled at new positions in staggered relation to the first indexed positions.

Title: Improvements in and relating to multiple effect evaporation processes and apparatus for juices and other liquids
IPC: C13B25/00
Filed: 1939-01-09
Abstract: 520,064. Multiple effect evaporators evaporating saccharine solutions. SHROFF, R. D. Jan. 9, 1939, No. 709. Convention date, Jan. 7, 1938. [Class 32] Cane and beet juices and like liquids are evaporated in multiple effect by heating the liquid to boiling point, subjecting the heated liquid in the form of a fine shower to reduced pressure, passing the vapours thus formed in heat exchange with the residual liquid, and again subjecting the thus reheated liquid in the form of a shower to further reduction of pressure, the successive steps being repeated as often as required. The liquid is passed through the heat exchange stage in a thin layer, preferably in film form, e.g. by passing it down the inner surfaces of tubes surrounded by the vapour. The size of the evaporating and heat exchange units may be reduced in each successive stage. The apparatus comprises alternate evaporator and heat exchange units A, B. The heated liquid is fed through a pipe 3 onto a perforated trough 1 from which it falls in a shower through the chamber A. Unevaporated liquid flows through tubes 11 in the heat exchanger unit B while the vapours formed pass off through a canvas-covered metallic screen 8 and flow downwardly over perforated plates 16 around the tubes 11. The condensate thus formed and residual gases are collected in a pipe 17 and passed to a vessel 20. The reheated juice is collected on a plate 26 and fed through a constant level valve C, forming a seal for the vapours, to a similar perforated trough in the next effect. Residual liquid is pumped through a pipe 24 to a further similar apparatus while condensate and gases are fed to a vessel 20 through a pipe 18 one end of which is connected to the vacuum pipe 22. The juice is preferably fed to the tubes 11 through feeder devices shown in Figs. 2 and 3, by which it is caused to flow in films down the insides of the tubes.
