| abstract | 504,370. Electrolytic pickling of metals ; diaphragms; electrodes. UNGERSBOCK, O. July 21, 1937, Nos. 20268 and 24859. Void. Convention dates, Aug. 3, 1936 and July 8, 1937. [Class 41] Metal articles are pickled in the anode space of an electrolytic cell; they may be connected as anodes or form intermediate electrodes. Preferably a number of cathodes enclosed by diaphragm vessels are arranged in a cell, leaving a common anode space. The acidity of the anolyte is regulated by the current. A diaphragm may be built up of short cylindrical sections and provided with a head of synthetic resin ; it may be suspended from the cathode rail. The diaphragm may alternatively consist of four earthenware plates mounted in a crossshaped frame. The electrodes and diaphragms' may be protected by grid-shaped guards. The anodes may be of lead, manganese dioxide, iron oxide or carbon. The electrolyte may be formed by preliminary electrolysis of a weakly acidulated almost saturated solution of ferrous sulphate until 5 per cent free sulphuric acid is present in the anolyte. When pickling iron the cathode may be of iron. |
