Abstract: A seal arrangement for a swimming-pool lining structure which is intended to be placed against the walls and bottom of a swimming-pool. The lining structure has metal wall panels and base sheets coated with plastic material on the surface facing the interior of the swimming-pool. The metal wall panels and the base sheets are jointed together with a profiled connection element at the vertical edge of each of the wall panels to form a junction region. The junction regions between said profiled connection elements and the ends of said wall panels and of said base sheets have an associated fluid plastic paste compatible with the wall panels.

Abstract: A rotary drum type dehydrator includes a rotary drum filter, a suction tube having an inlet and an outlet, said inlet communicating with inside space of the rotary drum filter, a compressed air supply tube connected to the suction tube in a portion thereof downstream of the inlet and communicating with the suction tube and an air compressor connected to the compressed air supply tube for supplying compressed air to the compressed air supply tube. Vacuum is produced in the inside space of the rotary drum filter by supplying compressed air from the air compressor to the suction tube through the compressed air supply tube. A filtered liquid receiving container is provided to collect filtered liquid and the outlet of the suction tube is disposed in the filtered liquid receiving container in such a manner that filtered liquid is jetted out of the outlet of the suction tube and is struck against a side wall of the filtered liquid receiving container or against surface of liquid stored in the container.

Abstract: A system for framing decorative art or mirrors with narrow frames comprising a frame assembly, a polygonal shaped planar sheet of rigid or semi-rigid material, and lateral movement preventing elements strategically located between the front face of the planar sheet and the frame assembly. The lateral movement preventing elements are strips of resilient compressible foam tape with pressure sensitive adhesive disposed on opposite sides thereof for adherence to the planar sheet and to the frame assembly. The planar sheet is thereby attached to the frame assembly at the location of each of the lateral movement preventing elements, thus providing strength to the frame assembly and preventing the lateral movement or bowing of any of the frame parts with respect to the frame assembly. In bonding the planar surface to the strips, the weight of the planar surface is borne mostly by the strips instead of the mitered joints, greatly reducing the tendency for mitered joints to be separated.

Abstract: A hermetically sealed container, in particular for cosmetics products, comprises an outer casing, consisting of a base (11) on which a lid (12) is positioned in a freely removable manner. According to the invention, from a part of said lid (12) there extends integral therewith an elastic gasket (16) which exerts a hermetic sealing action against an opposing surface (18) of said base (11).
