An automatically synchronized time indicating system comprises means for transmitting primary correction signals to a plurality of time indicating devices and means for substituting a secondary correction signal in the event of failure of any primary correction signal. A master clock 1 produces electrical timing pulses every second and these are converted by a translator 2 into high frequency timing signals which are passed, via a coupling device 4 and a communication channel 5, to drive a pulse-driven clock 11, an electronic digital clock 13, a programme or time-stamp or like clock 14, and a plurality of slave clocks 16 coupled to a repeating relay 9. Additionally two synchronous clocks 10 and 12 are operated from a power supply mains via the channel 5. Periodically, e.g. hourly, correction signals are received via a radio receiver 7 and pass via a selector 6 to a translator 8, which converts them into high frequency signals which pass via a coupling device 15 to the channel 5 to synchronize all the clocks 10 to 14 and 16. If, however, a correction signal is not received by the receiver 7 during a predetermined period a control unit 3 produces a secondary correction signal which passes to the clocks 10 to 14 and 16 via the units 8, 15.

In the described embodiment the A.C. voltage across supply loads 21, 22 is taken to be representative of the voltage across the slag layer and is applied to a circuit comprising members 27... 30 to produce a smoothed rectified voltage free from supply harmonics but including the fluctuations to be sensed. Application of this voltage to members 32, 33 removes the D.C. component and produces across a resistor 34 an A.C. voltage representative of the fluctuations, which voltage is rectified by a diode 35. The resultant voltage is applied to an integrating circuit 37, 38, 39 whose output is applied to a resistor 40 for comparision with a reference voltage U #  applied to resistor 43. The error signal developed across resistor 44 is applied to a regulator 47 which controls the driving motor 11 to vary the feed speed of the electrode 1 or, in extreme cases, to reverse the direction of feed. A current transformer 26 may be used if the current through the slag layer is to be the control parameter. Fig. 3 shows the fluctuations for the electrode (a) insufficiently immersed, (b) correctly immersed and (c) over-immersed, these fluctuations appearing across capacitor 33 and having an amplitude and frequency dependent on fixed parameters such as construction and size of the furnace, the nature of the slag and electrode 1 and the depth of immersion. A signal representative of these fluctuations may be obtained by integrating the whole waveform or positive or negative portions thereof, by counting positive and/or negative pulses or only pulses above a predetermined amplitude, in which case limiters may be employed in the control circuit. Application of the invention to D.C.-supplied electoslag apparatus is envisaged.
