Date Jan. 26, 1995A rotator includes an axle and an associated rotor component having lamellar vanes. A case component surrounds the rotor component. Chambers arranged symmetrically in relation to the axle are disposed between the lamellar vanes. These chambers are pressurized by oil fed through feed and outlet openings connected to the chambers. Bearing members are arranged in an axial direction on both sides of the rotor component. A conical bearing carries the axial rotor load and is formed by a conical arrangement of juxtaposed surfaces defined by the case and axle. The case includes channels leading from the chambers to the conical surfaces for communicating pressurized oil thereamong. The conical arrangement includes spaced gaskets. Oil pressure applied between the conical surfaces raises the axle off the case. In the absence of oil pressure, the conical surfaces lock as a result of friction between the case and axle.

Date Dec. 21, 1995A method and a device for finishing the surface layers of the machine reel (13) that is formed during reeling of the web (P). In the method; a member (20) that presses the web is brought onto the face of the reel (12) that is being completed before the reel (12) that is being completed is transferred to the reel change position. The full reel (12) is transferred to the reel change position so that the member (20) that presses the web during nip-free reeling forms a contact with the web, which contact prevents access of air between the web layers, and follows the full reel (12) during its transfer to the reel change position. During the reeling of the surface layer to be finished, the member (20) that presses the web is shifted apart from the face of the reel (12) that is being completed along such a path (D) of movement that the member (20) that presses the web maintains a contact of the desired extent with the face of the reel (12) that is being completed.

Abstract: The invention relates to a process for the purification of metals and in particular aluminium by fractional distillation. The process which comprises: (a) causing progressive solidification within a volume of liquid metal which is maintained in the vicinity of its melting point in an externally heated container by immersing therein an internally cooled body; (b) collecting at the bottom of the container all of the small crystals which are formed, (c) by compacting causing sintering of the small crystals to produce large crystals; and (d) separating the purified fraction consisting of large crystals from the liquid fraction which is enriched in respect of impurities, by tilting the container; is characterized in that, to increase the purification action, the container is maintained in its tilted position to drain off the purified fraction. The invention is used in particular in the purification of aluminium where it makes it possible for example directly to reduce the amount of iron from 800 to 1 ppm.

Abstract: A method for automatically placing objects on a surface in proximity to corresponding predetermined locations without collision with such locations or other objects by defining a distance dependent attractive force between each object and the corresponding location which increases with increasing distance between the object and the location, and defining distance dependent repulsive force between each object and its neighboring objects and locations, such repulsive force decreasing with increasing distance.  The initial position for each object is established in proximity with the corresponding location in accordance with predetermined criteria.          Thereafter the motion of the objects under the influence of such forces and of a frictional retarding force are determined by marginally stable incremental integration of such motion. The objects are statically placed at a predetermined target distance from the corresponding location at the position around the location at which the sum of the absolute values of the magnitudes of the forces acting on the object is at a minimum.
