Title: A rolling mill for the reduction of elongate stock
IPC: B21B31/18
Filed: 1968-07-23
Abstract: 1,240,149. Rolling mills. SIEMAG SIEGENER MASCHINENBAU G.m.b.H. 23 July, 1968 [5 Aug., 1967], No. 35073/68. Heading B3M. A rolling mill includes skewed rolls 37 which are rotated in a carrier 10 about a workpiece 15 such that the rolls feed the workpiece forward but do not rotate it. The rolls are driven through bevel gearing by planet wheels 44 mounted in the carrier 10, a driving pinion 47 serving to rotate the carrier. The planet wheels mesh with a sleeve 11 which is normally stationary. If, however, rotation of the workpiece is sensed by a detector 54, appropriate signals are fed to a motor 14 driving the sleeve. The sleeve is then driven to prevent rotation of the workpiece. The rolls are axially adjustable.

Title: Improvements in and relating to methods of reclaiming the mounts of burned-out electric lamps
IPC: H01K3/30
Filed: 1934-12-06
Abstract: 440,586. Repairing electric incandescent lamps. LAMP PATENTS, Ltd., 78, New Oxford Street, London.-(Freeman, W. R.; Teaneek, New Jersey, U.S.A.) Dec. 6, 1934, No. 35084. [Class 39 (ii)] In repairing or reclaiming the filamentsupporting mount removedfrom a burnedout pipless electric incandescent lamp, the flare of the mount is severed from the bulb and heated to a plastic condition and moulded outwardly to the correct shape for sealing into a new or reclaimed bulb ; the button carrying the filament anchors at the end of the stem is cut-off and a new button formed thereon at a predetermined distance from the flare ; the original filamentengaging hooks at the ends of the leading-in wires within the bulb are cut off and new hooks formed, and the sealed end of the exhausting tube is cut off and a new length of tubing fused thereto. The cap is first removed from the burned-out lamp by heating it to soften the cement and then pulling it off, as described in Specification 405,525, after which the flare 15, Fig. 2, of the mount is severed along a line 13 by flames 15, while the sealed end 18 of the exhausting-tube 16 is severed by a cutting-disc 20 on a rotating shaft 22 which also revolves in a path 24 about the axis of the lamp bulb 10. A striking-lug 21 adjacent to the cutting-disc assists the severing of the sealed end of the tube. The mount is removed and the flare 45 heated in any known manner to soften.it before it is reshaped by devices preferably comprising a member 46, Fig. 11, carried on a shaft 48 which rocks it downwardly and simultaneously revolves in a path 49 about the axis of the mount, after which the flare is placed upon a stationary anvil 50, Fig. 12, and subjected to the pressure of a moulding tool 53 at the end of a rocking-arm 54 which also revolves about the mount along the path 56. The flare is finally shaped and trimmed to the required size by placing it upon a cylindrical anvil having a top surface of slightly steeper curvature than the anvil 50, and subjecting it to the pressure of two diametrically opposite dies, the extruding edge of the flare being trimmed by vertical cutters. The means for severing the hooked inner ends 75, Fig. 18, of the leading-in wires 70 comprises four co-operating members 71-74 which flatten and hold the end of the wire while the hook is severed by a knife 76, the members then moving progressively into the position shown in Fig. 20, after which a.new hook 82, Fig. 22, is formed at the flattened end by the members operating to bend it before a plunger 81 descends to depress it into an aperture in the member 74. A new length of exhausting tube is fused on to the end of the tube 16 by bringing the ends of the tube into abutment and subjecting them to heat and pressure. The outer portions of the leading-in wires are straightened by gripping them between spring-pressed jaws which are moved downwardly and draw the wire between them.

Abstract: 1398856 Welding by pressure GENERAL MOTORS CORP 27 July 1972 [19 Aug 1971] 35091/72 Heading B3R In a method of diffusion bonding at least two abutting annular layers 7, 8, Fig. 1, of a laminated workpiece 6 together by the application of heat and radial pressure the workpiece is mounted on a cylindrical plug γ, e.g. by being wound on in the form of strip, and the workpiece and plug are inserted into ring 3 having a lower coefficient of thermal expansion than the plug 4. The assembly is then heated and the radial pressure thus created diffusion bonds the layers together. The workpiece 6 may be a seal ring having in perforate layer 7 and perforate layers 8 which may be nickel plated to improve the bonding process.

Abstract: 1,059,456. Filtering molten wax. ROSAEN FILTER CO. Aug. 17, 1965 [Nov. 2, 1964], No. 35123/65. Heading B1D. In a filter incorporating thermostatically controlled heater 80, liquid flows from inlet 16 to outlet 14, radially inwards through filter element 52, and clogging causes element 52 to be moved leftwards against spring 34 by increasing differential pressure, the movement being indicated by an external pointer (62), (Figs. 2, 3, not shown). Further movement carries member 42 over slots 56 in boss 46 to by-pass element 52. Heater 80 is mounted on removable end cap 18 of housing 10 and extends inside cylindrical element 52 or outside (Fig. 4, not shown). The filter is used to filter molten wax, and heater 80 may be used continuously or during shut-down. A sight window 70 is mounted in removable plug 66.

Abstract: 1,033,476. Blow-moulding machines. SOLVAY & CIE. Aug. 28, 1964 [Aug. 29, 1963], No. 35330/64. Heading B5A. In an extrusion-blow moulding apparatus, a plurality of single cavity moulds 8, 108 and their associated blowing nozzles 32 are mounted on a rotatable carrier 6. The carrier is rotated continuously to bring the moulds below the extruder 9 to receive the extrudate, the mould being opened in advance by a toggle mechanism 15, 17 actuated by a rotating cam 19 and, at the same time, a cam 41 on the extruder head engages a roller 40 to move the blowing nozzle 32 away from the mould. The mould halves 8, 108 close on the extrudate under the pressure of the springs 24 and the blowing nozzle 32 is returned to the mould by springs, the mould closing movement being braked by a dashpot device. Air is supplied to the blow nozzle to effect expansion of the tube, the blowing nozzle again retracted and, on opening of the mould, the article drops out. The retraction of the nozzle may be delayed so that the article is ejected by an air blast from the nozzle. The articles may fall into a delivery funnel.

Title: Improvements in and relating to carburetters

Abstract: 619,284. Spray carburetters. SHARP, E. P., and MORRELL, S. C. Nov. 29, 1946, No. 35493. [Class 7 (iii)] A carburetter comprises a fuel jet 7 controlled by a needle valve 8 mounted co-axially with a throttle valve 5 located on the engine side thereof, rotation of the valve simultaneously moving the needle valve or jet axially to control the fuel, the intake air being induced through a toroidal passage 4 as an annular stream around the jet. Air entering through ports 3 and annular passage 4 sucks fuel from a jet 24 fed directly at 12 from a fuel tank and controlled by the needle 8 carried by the throttle valve 5 having a screwed flange 27 which on rotation causes slight axial movement of the valve and hence of the needle 8. The lever 32 controlling the throttle valve is connected by a link 34 to a ported disc 38 controlling the air ports 3, and the needle 8 is screw-threaded for initial adjustment. The fuel, filtered at 13 and emulsified by air entering at 19, flows through passages 23 in a member 21 guiding the end of the needle 8, the spraying orifice being formed in a cap member 24 screwing on the member 21. In a modification the needle valve is mounted in the member 21 and is screw threaded to produce axial movement when rotated by means of a link in conjunction with the throttle valve. Two induction passages feeding different sets of cylinders may be controlled by the valve 5, which may be replaced by a ported disc throttle valve. An automatic or manually controlled extra-air valve may be provided on the induction passage 6, and the fuel orifice may be varied by movement of the jet member over a fixed needle valve. A gauge may be fitted across the mixing chamber, and clutching means may be provided to permit the air inlet valve 38 to be operated independently when desired.
