Hr:i:ni lts process, as employed by the Neuhausen Alurninium-Industne-Aktien-Gesellschaft, consists infusing and decomposing pure alumina by an electric vessel used for the reduction and fusing processesconsists of an iron box lined with charcoal, which isconnected by the copper wires a (see Figure) with the. Psocess. negative pole. The lower ends of a number of carbon-rods,serving as anode, are placed vertically in the box, as shownin the figure, the rods being held together by a frame c,which is connected with the wire b. At the commencementof the operation small pieces of copper are placed at thebottom of this vessel, and fused by means of the alumina is added, which is fused and decomposed bythe current. The aluminium produced is run off at d, asshown in the figure, and cast into moulds. If aluminiumbronze is required, copper and alumina must be added atthe same time and in the necessary proportions. Theworking capacity of the factory is 1,000 kilos, of purealuminium in 24 hours.—H. S. Alloys of Iron and Chromium. Including a Report byI. ( Ismond. B, A. Hadfield.
