  • Apparatus for anodic protection against corrosion of metal objects in contact with electrically conductive media
    Patent number: 4138323
    Abstract: The apparatus comprises self-contained potentiostatic devices, for control of the potential of objects, electrically connected via a controlled change-over switch to reference (standard) electrodes, auxiliary electrodes and cathodes in contact with an electrically conductive media in said object. The apparatus includes a stand-by power source connected through the change-over switch to the objects. Connected to the change-over switch control circuit is a means for the potential of the object.The potentiostatic devices form, together with the reference and auxiliary electrodes and the objects, independent control circuits.When the potential of one of the objects deviates from the preset value, the means for sensing the potential generates a signal for the change-over switch to connect the stand-by power source to this object.
