Abstract: The spent anodes to be stacked are vertically suspended by their lugs to hooks.The anodes are lifted from the hooks and then rotated alternately 90.degree. and -90.degree. around a horizontal axis; the rotated anodes are lowered to a lower position wherein they are released; the released anodes form a pile on a support positioned under said lower position; and the support is lowered in such a way that the top of the anode pile being formed on it remains under said lower position.

Abstract: Process and apparatus for separating a suspension bar (14) from an electrode (11) that is vertically suspended by this bar and that comprises, besides this bar, an electrolytic plate (12) and one or several suspension loops (13) fastened to the plate, the suspension bar extending through these loops.The suspension bar (14) is first relieved of the weight of the plate (12) by bringing the electrode (11) in a horizontal position in which its plate (12) is caused to rest on a support (34 or 34').The position of the bar (14) is then changed with regard to the position of the plate (12) by moving the support (34 or 34') with the plate (12) in a direction parallel to the longitudinal axis of the bar (14) while retaining the latter.

Abstract: In an apparatus for conveying dripping electrodes, a drop collector having a plurality of parallel gutters is coupled to the conveying apparatus by a frame. The gutters are coupled together in one or more series of parallel gutters and are displaced by a motor driven endless chain system between a work position underneath the suspended dripping electrodes and a rest position which permits the electrodes to be inserted into or extracted from electrolysis cells by the conveying apparatus. The gutters include outlet orifices which communicate electrolyte from the dripping electrodes to a reservoir formed in the frame which couples the drop collector to the conveying apparatus.
