US Patent 7854825 Symmetical double contact electro-winning

A symmetrical double-double contact mechanism for an electro-deposition mechanism. Using a base insulator, a cap block insulator is formed to support four series of electrodes of two different types (anode and cathode). Because of the contact mechanism employed, redundant contacts are provided so that should a short occur, alternative electrical pathways are available to maintain operation of the affected cathode or anode.
