Abstract: 420,757. Electrolysis. MONSERRAT, M., 36, Rue Carmen, Barcelona, Spain. June 7, 1933, No. 16387. [Class 41] In the electrolytic production of insoluble or only slightly soluble metallic compounds such as white lead, the electrolyte containing dissolving and precipitating agents is introduced by an insulating tube 3 near the cathode 1 and passes towards the anode through a fabric diaphragm 4. Holes may be provided at the base of the cathode for passage of electrolyte to the opposite side. The rate of flow through the diaphragm should be sufficient to prevent deposit of metal on the cathode. In the apparatus shown the diaphragm 4 is applied to a frame 2 of ebonite or other insulating material mounted on the cathode. White lead is produced by electrolysis of a slightly alkaline solution of sodium chlorate containing carbonic acid between a lead anode and lead cathode. Cuprous hydroxide is produced by electrolysis of a 15 per cent solution of sodium chloride maintained slightly alkaline between a copper anode and copper cathode.
