摘要： The present invention is directed to a method of minimizing shunt currents in electrochemical devices which have a plurality of cells connected, at least in part, in series and which have an electrolyte which is a common electrolyte to at least two of the cells and which includes shared electrolyte, whereby an electrical electrolytic conductive bypass path is created around such cells and through said shared electrolyte, resulting in undesirable shunt currents. The method involves applying a protective current through at least a portion of said conductive bypass path through said shared electrolyte in a direction which is the same as the shunt current through said shared electrolyte and of a magnitude which effectively at least reduces said shunt currents. Thus, a single protective current is applied in series with at least a portion of the conductive bypass path such that shunt currents are minimized, and preferably are totally eliminated. The present invention is also directed to an electrochemical device having means adapted for applying the protective current thereto.

摘要： PURPOSE:To accurately detect the existence of short-circuit between poles, by connecting plural electrically conductive members for short-circuit detection provided on the anode with the voltage detector in parallel and measuring the voltage between the anode and the above parts and then, giving an alarm only when measured value exceeds the standard value set up on the detector preveously and the above condition is continued for a fixed time. CONSTITUTION:The plural electrically conductive members 3 provided on the anode 1 through the insulating member so as to project on the cathode side, are connected with the voltage detector 11 is parallel and the voltage value Vo between the members 3 and the bus bar 10, is measured. For example, Vo is raised by increasing the voltage V3 when the distance between poles abnormally approaches the position of the conductive member 3' and the member 3' is m contact with the cathode mercury face and then, Vo exceeds the standard value set up on the detector preveously. There is no possibility of giving a false report by operating the alarm device 19 only when the above condition is continued exceeding the set up time in the timer circuit in the detector.

摘要： An electrical unit for sensing a steady magnetic field intensity produced by the flow of direct current is mounted in a carriage a fixed distance from the running surface of the carriage and is electrically connected in circuit with indicating means, which may be visual means, such as a light, or an audible alarm or both, energized in response to the sensing of a magnetic field of intensity greater than is produced by electrical current flow of up to a predetermined normal maximum amperage. The carriage is preferably of sled formation adapted to be pushed or pulled across a multitude of electrode suspension bars arranged in series along electrolytic cells in an electrolytic tank house, which bars serve to conduct current to the electrodes. The sensing unit is advantageously a magnetodiode, but may be any one of a number of possible alternatives, e.g. reed relays, electrically connected in suitable control circuitry.
