Abstract: 1,176,921. Automatic regulation of arc furnaces. WIENER SCHWACHSTROMWERKE G.m.b.H. Jan. 13, 1967 [Jan. 13, 1966], No. 1999/67. Heading G3R. In an automatic position control system for the electrodes 12, 13, 14 of an arc furnace 11 of the type wherein each electrode is controlled by a respective reversible servomotor 30 in response to the difference between signals representative of the arc voltage and electrode current, the amplifiers 31, 32 to which the error signal is applied are respectively shunted by compensating delay circuits comprising networks 35, 36 in series with a common resistor-capacitor network 37, 38. Each network 35, 36 comprises a number of parallel resistors each in series with a differentlybiased diode chosen to produce a desired non- linear voltage-resistance characteristic, so that the time constant of charging of the delay circuit varies inversely with the value of the difference signal. The networks 35, 36 are connected to the outputs of amplifiers 31, 32 through thyristors 33, 34 which are controlled by the amplifier outputs and which, when non-conducting, allow capacitor 37 to discharge through resistor 38, the time constant of discharge of the delay circuit being much larger than its time constant of charge. In operation, one or other of the amplifiers 31, 32 responds according to the sign of the difference signal to energize the appropriate relay 28, 29, and the non- linear nature of the compensating delay circuit provides an aperiodic correcting action to stabilize the control system and prevent hunting. The detailed functioning of the compensating circuit is discussed, Figs.3,4 and 5 (not shown) in relation to a known control system having a compensating circuit with a fixed time constant of charge, Figs. 1 and 2 (not shown).

[Class 7 (v)] Energizing mechanism for successive application to a number of engine starting units comprises a undirectional motor 16 and a pair of aligned shafts 40, 61 driven thereby, each of the shafts 40, 61 being adapted to receive and hold a separable work-engaging shaft 71 for coupling one or other of the shafts 40, 61 to one of the engine starting units. The unit can thus be driven in either direction without reversing the motor 16. As shown, the device is portable, the motor 16 being mounted in a housing 5 having a handle 7 and connected by members 11-13 to housing sections 8-10 enclosing gearing by which the shafts 40, 61 are driven from the motor 16 through a drive shaft 33 enclosed in the member 12. The driven shafts 40, 61 are provided with pockets 74, 75 for engagement by a spring detent 73 in the work-engaging shaft 71. A screw cap 81 is placed over the shaft 61 or 40 not in use and an apertured cap 83 over the one in use. The drive shaft 33 has a pinion 37 driving a crown gear 39 integral with a sun wheel 41 engaging planet gears 42 meshing 'with a toothed ring 43 secured to the housing sections 9, 10. The planet gears are carried by the element 46 of a multi-plate clutch 47, the inner sleeve 50 of which is threaded on the driven shaft 61, to which the shaft 40 is connected by splines 68. Clutch springs 48 are backed by a face-cam plate 49 splined on the sleeve 50 and bearing through balls 51 on a cam sleeve 52 coned to engage a cone clutch or. brake 54 sliding on guide pins 56, as described in U.S.A. Specification 2,110,469. Adjustment of clutch spring pressure is effected by a nut 64 on the sleeve 50. When the sleeve 50 is driven through the gearing and clutch 47, the shaft 61 is drawn to the right until its collar 62 abuts against the sleeve 50 ; this allows springs 57 to engage the cones 54, 52, retarding rotation of the cam plate 52, so that the cam 49 compresses the springs 48 to tighten the clutch 47. The cones 52, 54, then slip and full torque is transmitted to the shafts 61, 40 and the member 71. Adjacent to the handle 7 is a trigger 91 which operates a switch for the motor 16. The trigger is attached to a bar 92 pivoted at 93 and having a ball-and-socket engagement with a plunger 92 acting on a toggle member 96, biased by a spring 97 to the position shown in Fig. 4 to hold switch contacts 98, 99 out of engagement until the toggle is shifted about its pivot 101 by the plunger 92.
