Title: Improvements relating to the manufacture of coated welding electrodes
IPC: B23K35/40
Filed: 1937-07-05
Abstract: 486,365. Coating welding electrodes by extrusion machines. ARC, Ltd., A. July 5, 1937, No. 18700. Convention date, July 4, 1936. [Class 87 (ii)] [Also in Group XXII] In making coated arc welding electrodes from wire previously cut into short lengths, the burrs formed on the ends of the wires during cutting are removed by rolling the wires axially prior to extruding the coating thereon. The cut wire lengths 1 are fed from a container 2 by a grooved roller 3 and after rolling at 4 are fed by a cam-operated reciprocating striker 5 through a gauge 9 into driven feed rolls 10, 11, which feed them through an extrusion die 12. The rolls and cam shaft are driven by toothed gears from an electric motor 20, which also drives the extrusion piston 14 by a rack 28 and pinion 27. In order to leave a bare end on the wires the extrusion chamber is closed at intervals by a slide 15 operated by an eccentric 17 in synchronism with the cam shaft; should the wire not be of the required diameter the gauge 9 is moved axially against the action of springs 33 and completes a contact at 34 to stop the motor through a relay 37 and switch 38. After leaving the die the wire is gripped at its bare end by cam-operated tongs 17 on an end 16 which is driven by bevel and worm gear 29-31 and draws it out of the die, whereupon the tongs are opened and the coated rod drops into an inclined position on a travelling conveyer 19. The conveyer may be driven continuously or intermittently at slightly greater speed than the speed rolls of rollers 32 or an endless band conveyer may be used. Should the wire stick to the tongs after opening thereof it closes contacts 36 and so stops the motor. The tongs may be cleaned by a rotary brush 41. An oil pump may be interposed before the piston 14 provided with means to operate auxiliary contacts to stop the motor if the oil pressure is exceeded. The wires may pass vertically through the extrusion die, being caught by tongs and placed on the conveyer after rotating through 90‹. The motor may be controlled by a hand switch 35 and has a crank 40 for ensuring a slow starting in view of the inertia of the coating-material.

[Class 40 (v)] In a system in which broadcast programmes are distributed over a power network by carrier currents, a simplex circuit with earth return is employed where the power conductors are protected by a continuous metal sheath, while a loop circuit is employed where the conductors are not so protected, as in overhead lines and in house wiring. Figs. 1, 2 show arrangements for changing over from one kind of transmission to the other by means of transformers h, k. Chokes f, u and condensers g, l serve to restrict the carrier and power currents to their proper channels. When the invention is applied to a polyphase network, the currents are applied to the conductors in the unprotected area in such a way that the sum of the instantaneous values of the potentials with respect to earth is zero.
