In a method and an apparatus for aligning the ends of two submerged pipelines to be jointed, the apparatus which is equipped with means for displacing and aligning the pipe ends, is allowed to be displaced relative to the pipe ends and the bottom of the sea during the alignment operation. The restraining force developed when the displacement and alignment means are actuated, is used to displace the frame relative to the base and the pipe ends, so as to allow the frame and the pipe ends to adopt a final position in which the finished aligned pipe ends define a curve having the largest possible radius.

Method for aligning two pipeline ends and apparatus for carrying out the

A filter comprising a vessel in the form of a closed drum which is rotatably mounted about a horizontal central axis, and a plurality of longitudinal, hollow, horizontal filter elements which are arranged in a ring. The filter elements extend between and are connected to the end walls of the drum for rotation about the central axis together with the drum. The peripheral surfaces of the filter elements constitute a filter surface which, upon rotation of the drum and the elements, will submerge into and emerge from the liquid to be filtered which is contained in the drum. At one end the filter elements extend through the end wall of the drum, and this end of the filter elements is open to permit unobstructed discharge of the filtrate. A blow tube with nozzle means is provided within each filter element, with the blow tube serving to remove solids deposited on the filter surface when the surface is above the liquid level in the vessel. Each filter element is rotatably mounted in the end walls of the drum, and means are provided for rotating the filter element about its longitudinal axis during the period in which the filter element is above the liquid level in the drum. A stationary through the upwardly facing opening of which lies above the liquid level, is positioned above the uppermost portion of the orbit of the filter elements for collecting and removing the solids detached from the filter surface.
