The cover 22 is of plastics material and has locating studs 24<SP>1</SP> which fit into recesses 75<SP>1</SP> in the contact holder 21 to retain the two parts together. These locating studs may have split ends, the split being non-symmetrical to give a stiff and a springy prong, the latter prong having a projection to provide a snap fit on a shoulder in recess 75<SP>1</SP> and being bevelled at its end. The cover 22 also carries insulating partitions 28, 28<SP>1</SP> which are positioned when the cover is fitted in position. Either the cover or the contact holder may have recesses for accommodating electrical components, and both have bearings for pivots for the armature. The armature 1 which is of soft iron and partly sheathed with insulating material rotates about central pivot pins in these bearings and deflects spring contact blades 31, 31<SP>1</SP> carrying moving contacts 3, 3<SP>1</SP> which co-operate with fixed contacts 32, 32<SP>1</SP>. An armature restoring spring 41 is riveted to each pole shoe 44<SP>1</SP>, the pole shoes being interconnected via a ferromagnetic material cap 39 fitted over the cover. Guide pins 13 and bosses 14 on the armature operate the spring contact blades. In the case of A.C. relays short-circuiting rings may be incorporated in the armature or pole shoes. In an embodiment of a biased relay contact holders and covers similar to those 21, 22 above are used, but each has an internally threaded half flange which form when the contact holder and cover are assembled together threaded apertures which hold adjusting screws, Fig. 11, not shown, which act on a spring to adjust the relay bias. In a further embodiment for use with a biased relay the contact holders have central flanges formed with locating pins for locating adjusting springs, Fig. 19, not shown. In this embodiment barium ferrite magnets are used in combination with AlNiCo magnets for temperature compensation.

Title: Electric arc welding
Inventor: BOUGHTON PETER
IPC: B23K9/10
Filed: 1968-12-20
Abstract: 1293350 Welding by fusion BRITISH OXYGEN CO Ltd 28 Nov 1969 [20 Dec 1968] 60770/68 Heading B3R [Also in Division H2] Apparatus for short circuit arc welding comprises a rectified single phase power source and an energy storage device together with a switching device which is operative to switch the energy storage device so that it augments the rectified single phase source during the periods when the arc is short circuit. By arranging that the switching device is responsive to the voltage between the electrode and the workpiece, the "dip frequency" can be greatly increased relatively to that in the prior art, namely in the order of 100-250 cycles per second. In a short circuit arc welding system a consumable electrode 4 is fed towards a workpiece 8 by means of feed rolls 6, the weld zone being indicated at 10. A single phase supply, obtained from an A.C. source E and a transformer T, is rectified by a full wave rectifier Z and fed to a smoothing circuit S. A regulating unit 12 is connected across the output of the rectifier Z and a serially connected switching device 16 and energy storage device 14 is connected to the outlet of the smoothing circuit S, in parallel with the electrode A and workpiece 8, the regulating unit 12 being connected to the junction between the switching device 16 and the storage device 14. When an arc exists between the electrode and workpiece the switching device 16 is non- conductive so that the arc is supplied only from the rectified single phase supply by way of the smoothing circuit S. When the electrode 4 " dips " into the weld 10 thereby short circuiting the arc, the switching device 16 becomes conductive and the energy stored in the device 14 augments the rectified single phase supply so causing rapid "burn-back" of the electrode 4 to re-establish the arc. The switching device 16 may be a diode or a thyristor and the storage device 14 a capacitor or an accumulator. The smoothing circuit comprises inductors and a capacitor in a T configuration and the inductors are wound on magnetic cores with non-uniform air-gaps therein. The inductors may have tapped windings and more than one circuit having series connected devices 14, 16 may be used.
