Title: Improvements in or relating to pressure welding
Inventor: DONELAN JAMES ARTHUR
IPC: B23K20/04
Filed: 1963-02-01
Abstract: 1,026,901. Welding by pressure. GENERAL ELECTRIC CO. Ltd. Jan. 27, 1964 [Feb. 1, 1963], No. 4226/63. Heading B3R. In pressure welding, the welding indentation is effected by one part of a tool assembly the depth of indentation is determined by the differential movement of said one part relative to that of another part of the assembly resulting from different elastic compressions of the two parts under the force to effect welding. For use in welding aluminium foil or thin sheet a tool assembly comprising a central part of steel with a flat welding rib sandwiched between a pair of cheeks of aluminium or aluminium alloy is employed, the assembly being held together by screws. The surface of the rib lies initially in the same plane as the surfaces of the cheeks but during welding when pressure is applied to the whole assembly relative movement occurs between the rib and the cheeks to provide the correct indentation for welding. A piece of wire which may be of zig-zag form may replace the plain rib being backed by block. In a modification for welding the seam of a tube formed from thin aluminium sheet a steel anvil roller is mounted below the seam and a welding tool comprising an aluminium roller and a smaller diameter steel welding roller is mounted above with the aluminium roller engaging the anvil roller and the steel welding roller engaging the seam. The load can be applied to the tool assembly through a backing roll or through the spindle mounting the steel and aluminium rollers. Instead of aluminium side cheeks, plastic cheeks may be employed. Reference has been directed by the Comptroller to Specification 988,883.

Abstract: 1,105,580. Corrugating tubes. GROTNES MACHINE WORKS Inc. 2 Feb., 1966 [9 Feb., 1965], No. 4660/66. Headings B3E and B3Q. A method of corrugating a hollow metal body of circular, elliptical or polygonal cross-section comprises forming corrugations by means of parallel rings of internal die-segments which are moved axially as they are expanded. Axial tension, produced by expanding the corrugations, may be used to move the dies axially, or (Fig. 1) they may be moved axially by the expanding forces applied, through a rod 49, by an hydraulic cylinder. The die segments (36), Fig. 9 (not shown), are held, by garter &c. springs 41, in tapered pockets 39, Fig. 3, in the opposed faces of rings 38a-38g which are carried by flanged sleeves 44 slidable on a support 31 fixed to a carrier 22. Rubber &c. O-rings 42 form the work-engaging surfaces of the die-rings, and bearing liners 40 are bonded to the segments 36 or the pockets 39. Axial movement of an end-plate 48 moves the rings 38b-38g axially and cams the segments 36 outwardly until the rings are in contact with each other. One or more of the die-rings may be made inoperative, Fig. 8 (not shown), by replacing two or more die-segments of the selected rings with others having tails (56) which extend inwardly and thus prevent relative axial movement between the cam-rings (38b, 38c, 38e, 38f) on each side of the diesegments.

Filed: 1921-02-09
Abstract: 179,328. Walsh, P. J. Feb. 9, 1921. Transmitters; telephonic repeaters. - Telephone transmitters and repeaters, of the kind utilizing the variable resistance of bismuth conductors when placed in a varying magnetic field, have the bismuth conductors arranged as flat non- inductively wound spirals placed transversely in a gap in an electromagnet core, which is energized by two coils, one in series with, and the other in shunt to, the bismuth coil or coils. As shown in Fig. 1, a mouthpiece 8 and diaphragm 6 convert the speech waves into vibrations of the pivoted armature 2 of an electromagnet 1. A number of flat spiral coils non-induetively wound and of bismuth wire are connected in parallel and are placed in a gap in the core of the magnet 1. The core also carries two magnetizing-coils 18, 22, of which the coil 22 is of low resistance. The line circuit comprises a battery 24 and series coil 22, and two parallel branches, one through the coil 18 and the other through the bismuth coils. The flux variations due to the movement of the armature produce corresponding voltage variations across the coils 18, 22 and also vary the resistance of the bismuth coils. The bismuth coils lie between insulating-plates and are placed parallel to each other between soft-iron discs attached to the sections of the magnet core. The resilience of the armature is adjusted by a screw 17 tapped into a non-magnetic bridge 15 and bearing against a spring 16. In a modification, the speech waves influence an ordinary microphone which is electricallv connected to a solenoid having its core attached to the armature 2. In another modification shown in Fig. 5 the magnet armature is omitted, the core 60 being closed except for the gap for receiving the bismuth coils 63. Voice currents in the local circuit 66 pass through the coil 65 and vary the flux in the core. The line circuit 74 comprises two parailel branches, one through the bismuth coils 63 and the other through a coil 71 of few turns wound over the microphone coil 65.
