    • A process and apparatus for treating or handling scrap anodes are disclosed, which process comprises the steps of transporting scrap anodes suspended vertically from a pair of rails with their shoulder portions mounted on said rails by means of pushing projections mounted on a chain conveyer at intervals and in a downwardly protruding manner, said rails being provided under said chain conveyer; thrusting up the lower ends of the scrap anodes by means of a rotating plate during this transportation so that said scrap anodes may take a nearly horizontal position, said rotating plate being disposed under the rails and adapted for rotating vertically; thereafter moving said scrap anodes onto a supporting means provided adjacent to the rails and adapted to move horizontally by a working cylinder; hereupon stopping the scrap anodes and separating said supporting means from the scrap anodes thereby allowing them to drop down while maintaining their nearly horizontal position; receiving them on a receiving stand; turning said receiving stand 180.degree. in a horizontal plane; and thereafter lowering the receiving stand by a distance corresponding to the thickness of received scrap anodes by means of a lifting means.

    • A wavelength division multiplexed optical signal transmission method, a wavelength division multiplexed optical signal transmission system and an optical repeater enabling the number of wavelengths to be detected without error even when optical noise is caused in the optical repeater and such functions as adjustment and monitoring of the level of a wavelength division multiplexed optical signal to be performed properly. An optical repeater processes controlled optical signals of different wavelengths individually based on a control optical signal that contains wavelength number information indicating the total number of wavelengths and the presence or absence of a controlled optical signal with respect to each wavelength. Thus, even when optical noise is caused in the optical repeater, the number of wavelengths can be detected without error and such functions as adjustment and monitoring of the level of a wavelength division multiplexed optical signal can be performed properly.
