Abstract
1458901 Automatic control of electrolysis OLIN CORP 26 March 1974 [10 May 1973] 13416/74 Heading G3R In an electrolytic cell with a liquid cathode and one or more adjustable anode sets, the current in each anode set is measured and compared with upper and lower reference signals which are adjusted in dependence on the total cell current. If the measured current lies outside the range defined by the reference signals the position of the anode set is adjusted. As shown, a horizontal mercury cell 1 with brine electrolyte has a series of graphite anode sets 2. The current in each set is measured by sensors 4, 5 and the measured value is temperature compensated by a thermistor 6. The resulting signal is fed through an amplifier 7 to comparators 8, 16 and also, together with signals from all the other anode sets, to a circuit 9 which averages all the input signals and supplies an output to an amplifier 10 which produces a common signal on a line 11. This signal is fed to pairs of potentiometers 12, 15 associated with each anode set, the setting of the potentiometers being chosen so that a desired proportion of the common signal forms a reference value for each of the comparators 8, 16. If the signal derived from amplifier 7 lies outside the range defined by the reference values, one or other of the comparators 8, 16 energizes a corresponding relay coil 13, 17, thus actuating a motor 14 which raises or lowers the anode set 2. If the signal on line 11 falls below a predetermined minimum level, its value is supplemented by a source 19. A digital voltmeter 21 can be selectively connected to the line 11 or to any one of the amplifiers 7 indicating measured anode currents. Operation of the anode adjusting motors is indicated to an operator by lamps 22, 23 and 26, 27 associated with relays 13, 17 and latching relays 24, 25 respectively.
