Abstract

334,871. Siemens & Halske Akt.- Ges. Jan. 17, 1929, [Convention date]. Addition to 307,747. Void [Published under Sect. 91 of the Acts]. Latex, coagulating.-The process for the electrophoretic deposition of rubber by alternating current according to the parent Specification is modified by the introduction of electrolytes into the latex itself or by saturating the porous moulds surrounding the electrolytes with electrolytes, instead of, or in addition to the introduction of electrolytes into the electrode spaces. The addition to the latex may be made when no porous bodies are employed. In an example, lead electrodes covered with plaster of Paris are saturated with a 20 per cent solution of calcium chloride and lightly rinsed in water before insertion into the latex. Using a voltage of 38 at 50 cycles and a current density of 0.0021 amps. per cq. cm., a total deposit of 2.15 gms. per watthour was obtained. Magnesium chloride, ammonium chloride, and acetic acid may be used as electrolytes.
