Rio Tinto Alcan | Date: 2013-04-12

This preheating connector for electrically connecting an anode stern to an anode frame of an electrolytic cell during the warm-up phase of the electrolytic cell, includes means of fixing to the anode frame, and bearing means designed to exert pressure on the anode stem in order to keep it pressed up against the anode frame, the fixing means and bearing means being configured and arranged so as to add on the preheating connector onto a so-called permanent connector for electrical and mechanical connection of the anode stem to the anode frame during the continuous operating mode of the cell.


The present disclosure provides processes for recycling spent pot lining carbon by-products (SPLCB) obtained from a caustic leach process. The process provides treating spent pot lining (SPL) or SPLCB with Ca/P-containing stabilizing agents.


A safety confirmation system includes a mobile terminal that receives early disaster information, a center apparatus that manages a safety status of a user of the mobile terminal, and a map server that provides map information. The mobile terminal holds destination information and automatically acquires current location information upon receiving the early disaster information. The mobile terminal automatically transmits the current location information to the center apparatus and the map server, and automatically transmits the destination information to the map server. The center apparatus receives the current location information transmitted from the mobile terminal. The map server searches for a return route from the current location to a destination, generates map information including the return route, and transmits the map information to the mobile terminal. The mobile terminal receives and stores the map information including the return route and displays the map information.
