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.

A method and apparatus for treating finely divided fibrous pulp with gas without overpressure in a continuous process. The bulk material is substantially continuously supplied to a reactor having one or more supporting floors having apertures of a shape and size which allow the finely divided material to form bridges across the apertures, said apertures also permitting a continuous flow of gas through the bulk material. The bulk material proceeds through the reactor as a consequence of the bridges being broken by breaking arms sweeping along the upper surface of the supporting floors.

A displacement pump of the blade or vane type comprising a rotor with two blades, said rotor being eccentrically mounted in the casing of the pump. The rotor with its blades provides for a first pumping effect so as to transport material in first partial volumes with a first pulsating characteristic having two maxima and two minima for every full rotation of the rotor. The rotor is constructed with circumferential sections between the blades, said sections being located inside the smallest circumscribed circle of the cross-section of the pump and uniformly merging with remaining circumferences of the rotor. Between the outlet and the inlet of the pump a pivotable flap is arranged. The flap with its front edge slidingly abuts against said circumferential sections of the rotor for thereby inducing a second pumping effect. This second pumping effect has a second pulsating characteristic also having two maxima and minima for every full rotation of the rotor. The maxima of said second pulsating characteristic coincide with the minima of said first pulsating characteristic, and the minima of said second characteristic coincide with the maxima of said first pulsating characteristic, for thereby providing a pump which yields a greater total pump capacity and gives a more even total supply characteristic.
