Abstract: Vehicle for handling various material such as nodes, ladles or operating units in rooms wherein a wide maneuver capacity is required in narrow spaces and/or in the presence of obstacles, impediments, such as industrial sheds, airports, areas for heavy means, and markets comprising a front driving and steering structure carrying a driver's cab, said structure being suitable to rotate continuously by 360° in both the clockwise and the anti-clockwise directions about its own vertical axis.

Abstract: Automatized equipment for the replacement of the anodes in the cells for aluminum production, comprising two modular structures suspended from saddles sliding on a bridge crane provided in the cell room, the first structure being provided with devices for crust breaking, the removal and laying of worn anodes on a platform translable on a special vehicle placed on a side of the cells, and then for hooking new anodes placed on the same platform and positioning them into the hollow space of the removed worn anodes and the second structure being provided with a device for cleaning the hollow space, and for collecting and transferring slags into a special container placed at the opposite side of the cells on a special vehicle, as well as of means for covering with alumina and/or other powdery materials the new repositioned anodes.

Abstract: Module for mechanized replacement of the anodes of electrolytic cells for the production of primary aluminum, constituted by a cage-shaped structure which can be hooked to a usual bridge crane, with said structure a control cab (8), a hopper, fork-shaped positioning elements, a telescopic arm (17) for clamping, unscrewing and locking anode bars, a crust-breaker device (11), a device for cleaning the upper surface of the worn anode and a skimmer device (14) being associated.

Abstract: Process for purifying the fumes emitted by electrolysis pots for the production of aluminum from fluorinated products, alumina and various components of the electrolysis bath, and for using again these products in the pots. The process consists in sucking the electrolysis fumes from at least a hole provided in the crust, and kept constantly open, by keeping under suction only the area surrounding said hole, in contacting the fumes with alumina, and in reintroducing the products fixed and/or retained on the alumina directly back into the same pot from which they have been emitted. Equipment for accomplishing the process, constitutes a cap placed in contact with the crust in correspondence of the hole, by a reactor of the fluidized bed type, or of the injection "Venturi" type, positioned in correspondence of the pot, with related filter and fan/exhauster.

Abstract: A powered vehicle for operating ladles and the like, in particular ladles utilized for tapping molten aluminium, which vehicle comprises an arcuate load-bearing structure substantially of the rigid bridge girder type resting securely on two opposedly located trucks associated with the bottoms and exteriors of the bridge girder end uprights, one of said trucks carrying a motor means and respective drive to at least one of the trucks, and the other carrying a fitted driver cab for an operator, associated with said bridge girder there being an additional bridge girder structure mounted for a vertical sliding movement along guides formed on the uprights of said bridge girder by hydraulic cylinders or the like, with whose opposite uprights there are associated, at opposite locations, projecting elements of cradle- or fork-like configuration, or the like, adapted to receive, support, and hold studs or pins standing proud of a ladle surface, at diametrically opposed locations thereon, whereby the ladle can be hooked
