<p>In an electrolytic reduction cell having anodes which are vertically moved through screw jacks, each driven through a worm reduction gear, a common motor is provided to drive a plurality of the jacks, each jack being driven through an individual disengageable torque-limiting clutch located between the motor and the input shaft of the reduction gear. This allows individual anodes to be raised and lowered or all the anodes, driven by the common motor, to be raised and lowered together. Reverse gearing may be arranged in the system to allow one group of anodes to be driven at the same speed but in the opposite direction to another group of anodes to allow the electrolyte to be agitated by anode movement without appreciable change of mean electrolyte level in the cell.</p> |
