Abstract: A method and means for application of anode covering material (ACM) in an electrolysis cell for aluminium production where the cell being of Hall-Héroult type with prebaked anodes. The cell contains a cathode pot with a rectangular footprint and a superstructure with a gas collecting hood that lays onto the top of the cathode pot. A floor construction at least substantially surrounds the cell at a level below the top of the cathode pot and ventilation openings provided with grates are arranged in the floor in the close vicinity to the cell. The superstructure's hood is provided with removable lids that are removed for giving access to the cell's anodes through openings. ACM is applied via a feed tube to cover the anodes and the deposit of ACM is supported by a shuttering.

Abstract: A subsea clamp connector for connecting the ends of two tubular members to each other, the clamp connector including first and second clamping elements, which are pivotable into a closed position in clamping engagement with the ends of the tubular members; and a replaceable locking unit for locking the clamping elements in the closed position. The locking unit includes an operating shaft, a first retaining member mounted to the operating shaft and configured for engagement with a shoulder on a holding member fixed to the first clamping element, and a second retaining member mounted to the operating shaft and configured for engagement with a shoulder on a holding member fixed to the second clamping element. The locking unit is detachably mountable to the clamping elements by insertion of the operating shaft sideways into slots provided in the holding members.

Abstract: A method and a system distribute fluidizable materials from a reservoir of materials to one or more material receiving units. The distribution system has at least two hydraulic levels between the reservoir and the material receiving units. The system further includes a fluidizing element with good dynamic response properties. The system can be used for distribution of alumina and/or fluoride to feeding equipment in electrolysis cells with a reduced consumption of fluidizing gas.

Abstract: The present invention relates to a method and a system for distribution of fluidisable materials from a reservoir (1) of materials to one or more material receiving units. In accordance with the invention the distribution system has at least two hydraulic levels between the reservoir and the material receiving units. The system further includes a novel fluidising element with good dynamic response properties. The system may preferably be used for distribution of alumina and/or fluoride to feeding equipment in electrolysis cells with a reduced consume of fluidising gas.

Abstract: The present invention concerns a method and device for reducing emissions of process gases from Hall-Héroult cells to the ambient air. The cells comprise an anode superstructure (1) with covers which can be opened for access to the cell's anodes, among other things. The anode superstructure comprises an extraction system for the removal of process gases, which extraction system is adjusted to remove a standised quantity of process gases during normal operation of the cell. The extraction system is designed so that an increased quantity of process gases is removed when the covers of the anode superstructure are opened. One embodiment of the present invention includes a vertical partition wall (10′) which is located inside the anode superstructure and contributes to an improved flow pattern in the anode superstructure.

Abstract: The present invention concerns a method and a device for separating and extracting fractions in a material flow of a material consisting of particles of different fractions. The device comprises a closed conduit (7) with an inlet end and an outlet end through which the material is transported. A separation chamber (17) is mounted between the inlet end and the outlet end. The separation chamber comprises at least one fluidisation element (13) at the base of the chamber and an extraction device (9) located in the upper part of the chamber. In use the present invention has proved to be particularly well suited to continuous separation of dust from a fluidisable mass where there is a need for high capacity.

Abstract: A method and an apparatus for filling a silo (1) with a fluidizable material. The arrangement includes conveying devices (5, 9) for supplying material to an upper area of the silo and a central material distributor (10). The material distributor includes a tank (29) which has an inlet (28) and one or more distributor pipes (26, 26′) for distributing material to one or more feed units (11, 11′)which convey the material down towards the surface of the material in the silo.

Abstract: A de-aeration device for the separation of solid particles from a gas includes a container with an inlet for the supply of the gas contaminated with particles and an outlet for the purified gas. The cross-section of the container is dimensioned in such a way that the gas velocity does not exceed the carrying velocity of the particles. The gas flow is deflected at the inlet so that it flows mainly sideways in relation to the direction of through-flow of the container. The outlet of the container is provided with a filter cloth.

Abstract: A separator for separating two or more materials of which one or more consist(s) of a particulate, fluidisable material such as aluminum oxide, from a material which can not be fluidised such as nails, tools, coke, pieces of wood, and lumps of oxide. The separator comprises a chamber (1') in which are located one or more screens (7, 9) and one or more fluidising/transport channels (8, 10) underneath, at angles established in advance. The separator has no movable parts.
