Abstract: 724,251. Cupping. ALUMINIUM LABORATORIES, Ltd. Oct. 13, 1953 [Nov. 3, 1952], No. 27682/52. Class 83 (4). A ring die assembly for use in conjunction with a cupping punch is characterized in that a ring die is floatingly mounted in a holder, the die and the holder co-operating to provide a self-centring action of the die when the die is disengaged from the punch and the die being free to move laterally on initial engagement by the punch. A press for making aluminium cans comprises a punch 1, a supporting ring 2 and a clamping member 3 between which an aluminium blank is clamped, and three ring dies 4 of gradually decreasing diameter assembled in a holder 7 by means of housings 5 and spacing rings 6. Each housing member 5 has an overhanging shoulder 8 upon which is formed a downwardly directed conical supporting face 9. A backing ring 10 is inserted in the bottom of the housing 5, the flat upper surface of the ring 10 supporting the ring die 4 during the pressing operation. A rubber ring 11 rests in a recess in the backing ring 10, said recess being chamfered at 12 to allow lateral distortion of the rubber ring when compressed. The top outer edge of the ring die 4 has a chamfered face 14 corresponding to the conical face 9 of the shoulder 8 of the housing 5 and the bottom surface of the die has an annular seating 15 for the rubber ring which is assembled under compression so that when the ring die is not in operation it is raised so that the chamfered face of the die engages the conical supporting face 9 of the housing member and the interaction of said faces centres the die in readiness for the next operation. During the working stroke the die is engaged by the blank and disengaged from the supporting face 9 and is momentarily supported only by the rubber ring so that the die is adjusted to any eccentricity of the punch before it contacts the backing ring 10. In a modification the ring die 4<SP>1</SP>, Fig. 2, is mounted on three or more springs 16 located within the housing and acting on a carrier 17 which holds the ring die. The lower supporting surface for the ring die is formed by a flat packing ring 19 resting on a hard resilient packing ring 20 both located in a groove in the backing ring 101 which is combined with the housing 51.

Abstract: 1,049,548. Coaxial cables. SIEMENS-SCHUCKERTWERKE A.G. July 2, 1965 [Aug. 5, 1964], No. 28234/65. Heading H1A. Discs of thermoplastic material are formed on copper wires 1 intended for use as the inner conductors of coaxial cables by an injectionmoulding machine 12, in which they are held stationary during moulding by clamps 14. The intermittent action with which they are pulled through the machine by a reciprocating gripper 13 is reconciled with even rotation of the supply reels 2 by a slack storage unit 5 between the reels and the moulding machine. For each conductor 1 the unit has a driving wheel 7, a fixed roller 8 and a movable roller 9, which presses on the wire and deflects it by an amount which varies according to its vertical position. The gripper is driven by an eccentric 17, so that it exerts a pull which varies in amplitude sinusoidally, and exact control of its stroke may be obtained by drawing it into its extreme positions by electromagnets (not shown). A second slack storage unit may be incorporated between the moulding machine and the take-up reels. The drive to wheels 7 may be interrupted if the rollers 9 fall below a limiting position.

Title: Improvements in or relating to a method of and furnace for the roasting of sulphide ores
IPC: C22B1/10
Filed: 1954-10-05
Abstract: <PICT:0786375/III/1> <PICT:0786375/III/2> Finely divided sulphide ores are roasted by injecting a suspension of the ore into a nonexternally heated chamber whereby the ore falls downwardly in a trajectory depending on the size of the particles and forms a layer in the lower part of said chamber, a gas containing free oxygen being introduced into the lower part of the chamber and spent gases being withdrawn from the uppermost part of the chamber.  Air for combustion is preheated to a high temperature before introduction.  The illustrated embodiments exemplify preferred features of the invention: in Fig. 1, a suspension of ore in air is injected into the chamber 1 through one or more nozzles 3 which produces a sheet 2 of ore (which may in general be 10-80 cms. thick) in which the finest particles immediately burn.  An inert gas, preferably cooled recycled furnace gas, is injected through nozzle 8 to limit the temperature and prevent scale formation on the furnace or ore agglomeration. The ore falls on to a sole plate in the form of a travelling band 5 and raking devices 6 attached to air conduits 7 ensure completion of the roasting on the band.  If desired, sulphated or incompletely roasted dust recovered from the gas stream may be reintroduced by means of screw 10.  A gas outlet 9 is arranged at one of the ends of the chamber.  Figs. 2-4 (not shown) illustrate the use of a vertical cylindrical chamber having a rotating sole plate on to which the ore falls.  The ore may be injected as in Fig. 1 or vertically upwards as a diverging sheet about the axis, or two sheets of ore may be oppositely directed from diametrically opposite points in the furnace wall.  Air and/or recycle gas may be introduced tangentially.  Fig. 6 is a cross-section of a rotary tubular furnace into which the ore is injected as in Fig. 1, and shows the layer 15 of ore and tangential nozzles 13 arranged to open in sequence and thus introduce air on to the surface of the one layer.  In addition, taking members may be used to agitate the ore.
