    Abstract: A cylindrical anode and a cylindrical cathode longitudinally spaced from one another with an insulating cylinder between them form one wall of an annular flow passage. The other wall is formed by a coaxial conducting cylinder which is known as a bipolar electrode because in operation it is anodic relative to the cathode and cathodic relative to the anode. In one embodiment the two electrodes and insulating spacer form the housing within which is mounted the bi-polar electrode. In another embodiment the bi-polar electrode forms the housing within which is mounted the cylindrical anode, insulating spacer and cathode. The electrolyte, such as brine, flows through the annular flow passage while current flows from anode through electrolyte to the bi-polar electrode along the bi-polar electrode back through the electrolyte to the cathode thereby, when the electrolyte is brine, generating sodium hypochlorite.

    Abstract translation: 一个圆柱形阳极和一个圆柱形阴极彼此纵向隔开，绝缘圆柱体之间形成环形流动通道的一个壁。 另一个壁由同轴导电圆筒形成，其被称为双极电极，因为在操作中它相对于阴极是阳极的并且相对于阳极是阴极的。 在一个实施例中，两个电极和绝缘间隔件形成其中安装有双极电极的壳体。 在另一个实施例中，双极电极形成壳体，其中安装有圆柱形阳极，绝缘间隔物和阴极。 诸如盐水的电解质流过环形流动通道，同时电流从阳极通过电解质流向双极电极，通过电解液返回到阴极，当电解质为盐水时，产生次氯酸钠 。

    Abstract: A PROCESS FOR TREATING INDUSTRIAL WASTES CONTAINING SULFURIC ACID AND METAL CONSTITUENTS COMPRISING SUBJECTING THE WASTES TO A CELL EQUIPPED WITH A PLURALITY OF ALTERNATELY POSITIONED POSITIVE AND NEGATIVE LEAD-ANTIMONY ALLOY ELECTRODES AND CHARGING THE ELECTRODES. THE LIQUID PORTION OF THE WASTE IS DISSIPATED AND A RESIDUE INCLUDING THE METALLIC CONSTITUENTS FORMS. A SECONDARY PROCESS IS ALSO DISCLOSED COMPRISING THE STEPS OF PLACING ADDITIONAL PICKLE LIQUOR IN A SECONDARY PROCESSING TANK, CONTACTING THE PICKLE LIQUOR IN THE SECONDARY PROCESSING TANK WITH THE EXTERIOR WALL OF THE CELL WALL TO THE PICKLE LIQUOR IN THE SECOND THROUGH THE CELL WALL TO THE PICKLE LIQUOR IN THE SECONDARY TANK WHEREIN THE LIQUID PORTION OF THE LIQUOR IN THE SECCONDARY PROCESSING TANK IS DISSIPATED AND A RESIDUE INCLUDING THE METALLIC CONSTITUENTS FORMS WITHIN THE SECONDARY TANK. THE METALLIC CONSTITUENTS MAY BE RECLAIMED BY A DRYING STEP OR BY AN AGNITION STEP.
