One of the most interesting featuresof the equipment is the Thury regulator,which automatically maintains an ap-proximately constant current at the fur-nace electrodes. Without this device thecurrent consumption would vary erati-cally even if an operator were constantlyendeavoring to correct the variations. Ittherefore saves labor and current, re-duces to a minimum the time required to prepare a charge, and by providing uni-form conditions keeps the quality of theproduct uniform. Each furnace electrode has a separateregulating mechanism
