Title: Power supply apparatus with remote control of power
IPC: B23K9/10
Filed: 1974-03-11
Abstract: 1471081 Power supplies for arc welding apparatus; control of DC motors J SAULSMAN 11 March 1974 10784/74 Headings H2H and H2J Apparatus for controlling the supply of power from a source 24 to a remote arc welding station comprises an operator responsive switch 20 for adjusting the level of power delivered from the source to any value between zero and full power without interruption of the power delivered to the station and for reversing the direction of change in the power delivered from the source without interruption of the power delivered to the station, and a sensor for detecting the change in power delivered. When the switch 20 (or S1) is moved by an operator to the INCR. position, a resistor R1 is connected in circuit and causes a transistor Q3 to conduct but a transistor Q4 is non-conductive. A transistor Q6 conducts and switches on a transistor Q8 which in turn switches on transistors Q9, Q10. Current therefore flows in one direction through a motor M1 which rotates a rheostat in the source 24 to increase the welding current. movement of the switch S1 in the opposite direction causes conduction of both transistors Q3, Q4 but since the base voltage of the transistor Q5 exceeds that of the transistor Q6, the transistor Q5 conducts whilst the transistor Q6 is non-conductive. Transistors Q7, Q11, Q12 are therefore switched on to supply current in the reverse direction to the motor M1 thereby decreasing the welding current. The motor speed and therefore the rate of change of the power delivered to the remote station may be preset by a potentiometer R7 adjusted by a control (29), Fig. 3 (not shown) on the housing 26. The sensor, which is connected to a conductor 34d, is an earphone or headphone supplied by an audio oscillator which is turned on at each operation of the switch S1 and supplies a tone to the welding operator to indicate the change of the welding current. In Figs. 7, 11 (not shown) the welding conductor 15 is used as one of the control conductors 34c, the switch S1 then controlling a circuit supplied with A.C. but isolated by a transformer from the main control circuit to prevent D.C. on the welding electrode being fed to the control circuit.

Abstract: 879,210. Unwinding from coils. SMITH & SONS (ENGLAND) Ltd., S. April 8, 1959 [April 8, 1958], No. 11080/58. Class 120(2) [Also in Group XXII]. Apparatus for assisting the unwinding of material from a coil by means which draw it off in an axial direction from one end of the coil, comprises a rotatable structure with an opening for the material disposed away from the coil, means on the structure for engaging the material so as to impart to it the rotation of the structure while permitting longitudinal movement of the material, means for rotating the structure at a rate in relation to that at which material passes through the opening that a twist of 360 degrees is imparted to the material for each convolution drawn off, and balance-means positioned on the structure on the opposite side of the axis of the structure from the means for 'engaging the material. Preferably, the coil is of wire and remains stationary during the unwinding and the twist imparted is in the opposite sense and to the same extent as that imparted by the drawing-off operation to prevent the formation of snarls. Wire from a coil 10 between cylindrical walls 11, 12 is drawn by the winding means 55 (Fig. 2, not shown) through an aperture 14 in a conical cover 13, through a hollow spindle 17, once around a pulley 31, and over a pulley 35. Pulley 31 is rotatably mounted in plates 23 secured to spindle 17, and pulley 35 is secured to a spindle 36 carrying a pulley 46 connected by a belt 54 passing over jockeys 47, 48 to a pulley 16 secured to spindle 17. Thus, when pulley 35 is rotated by the wire or otherwise pulley. 46 rotates pulley 16 and shaft 17, so that plates 23 are rotated; accordingly pulley 31 and the wire around it are rotated, the arrangement being such that the wire is twisted through 360 degrees for every convolution drawn off the coil 10. Pulley 35 lies between impregnated rings 60, 62 the former fixed and the latter adapted to be pressed against the pulley on rotation of a nut 68. The wire also passes between friction-plates 33, 73.
