Inventor: NEEDHAM JAMES CHRISTOPHER
IPC: B23K9/235
Filed: 1967-04-05
Abstract: 1,188,024. Welding by fusion. WELDING INSTITUTE. 2 April, 1968 [5 April, 1967], No. 15693/67. Heading B3R. [Also in Division H2] In arc welding using electrodes 20, 13 connected in series to a common power supply, a consumable electrode 20 is connected to the positive terminal and a gas shielded non- consumable electrode 13 is connected to the negative terminal. The non-consumable electrode may act as a pre- or post-heater and a tungsten electrode gas shielded torch 10 or a transferred arc plasma torch may be used. The consumable electrode 18 may be part of a submerged arc welding torch or a gas shielded arc torch using a short circuiting arc or a pulsed arc or with spray or globular transfer. Reference is made to aluminium and steel consumable electrodes and workpieces and argon, carbon dioxide or 20% carbon dioxide, 80% argon as shielding gases. Two parallel connected tungsten electrodes in line with or transverse to the welding seam, or one preheating and one post-heating tungsten electrode may be used. A high frequency current may be fed to the tungsten electrode. The starting voltage for the tungsten electrode torch 10, Fig. 4, is supplied through a starting resistance 41 and a temporary connection 40 to the work 12, the current being limited by a parallel resistance 42 and a series choke 44. After the consumable electrode has been fed to the work to strike its arc and to complete the welding circuit, the temporary connection 40 and the resistances 41, 42 are disconnected and the choke 40 is shunted. In a modification a separate current source is used to strike a pilot arc to initiate the tungsten arc. The consumable electrode arc strikes when the electrode is fed. Either arc may be provided with a by-pass resistor to provide adjustment of the power balance between the arcs.

IPC: D02J1/22
Filed: 1951-07-03
Abstract: <PICT:0710708/IV (a)/1> The permanent elongation of a finished thread, yarn or cord of regenerated cellulose or cellulose derivative is reduced, and the strength and resistance to fatigue after continued dynamic stress are improved, by subjecting it while it is travelling in continuous manner to a rhythmically alternating tensile stress of between 10 and 50 per cent. of its ultimate tensile strength so as to apply at least 100 alternations of load to each elementary length of the thread, yarn or cord.  The treated material is particularly suitable for tyre cord.  As shown, thread, yarn or cord, or cord fabric, is taken from a spool or ball 1 and passed round driven rolls 2, 3, 4.  The speed of these rolls may be varied by means of a regulable drive.  The travelling material is stretched by the assembly of rolls 5, 6, 7, which have a greater peripheral speed than the first set of rolls.  Winding takes place on a beam or spool 8 which is provided with a friction drive. Pulsating movement is imparted by a reciprocating loading roll 9. The frequency of pulsation may be 500 strokes of the loading roll per minute.
