摘要： Means to plate silver from photographic hypo combines an electrolytic cell having a plating cathode with means to feed hypo solution to the cell at various constant volume supply rates and with means to supply electric energy to the cell comprising means to restrict and maintain the voltage and amperage thereof within maximum values to various constant rates corresponding to the respective constant hypo supply rates. In the cell hypo supply first moves slowly in heat-absorbing contact with a non-plating portion of the cathode, then into a plating zone.
