摘要： A device for increasing the oxygen concentration in a subsurface stratum of a thermally stratified body of water. The device comprises a flexible tube (13), which is surrounded by a flexible shell (12). Compressed oxygen-containing gas is introduced through first nozzle means (29) at the lower end of the tube and through second nozzle means (31) into channel means (34) between the shell (12) and the tube )13). There is an upward flow of water in the tube and a downward flow in the channel means (34) around the tube.

摘要： An expansion body for constructions like piles or anchorages located in the earth is adapted for insertion into the ground in a compact shape and expanded therein to an expanded shape. The expansion is achieved by unfolding a folded metallic casing (11) by filling it up with pressurized fluid. Each end of the elongated body is sealed by a closure comprising a socket (16, 17) with a sleeve (18, 19) encircling the near end part of the casing and a bottom plate (20, 21) with spacing means (22, 23) projecting into the inside of the casing. The sleeve (18,19) and spacing means (22, 23) define an annular space (26, 27) in which the end parts (14, 15) are kept in a folded position when the body is expanded.

摘要： In a hydraulic torque impulse tool having a power rotated inertia drive member (10; 110) and a hydraulic fluid chamber (19; 119) a piston (30; 130) is supported in the fluid chamber (19; 119) for reciprocating movement in a plane transverse to the rotation axis of the drive member (10,110). The piston (30; 130) and the output spindle (11; 111) are provided with cam means (42,43,44; 142,143,144) by which the piston (30, 130) is reciprocated in the fluid chamber (19; 119) at relative rotation of the drive member (10; 110) and the output spindle (11; 111) of the tool. The piston (30; 130) and the fluid chamber (19; 119) have seal means (31, 28; 131, 128) by which one fluid chamber compartment (38; 138) is sealed off from another (39; 139) during a certain portion of each piston stroke, thereby accomplishing an instantaneous pressure build-up in one of the fluid chamber compartments. The resulting reaction impulse on the piston (30; 130) is transferred to the output spindle (11; 111) via said cam means (42,43,44; 142,143,144). An adjustable bypass valve (50; 150) is arranged to limit the peak pressure in the fluid chamber (19; 119) as well as the torque impulse magnitude delivered by the tool.

摘要： A valve device for controlled pressurization of a pressure fluid system (35). The device comprises two coaxial valve bodies (9, 13), one (11) for controlling flow communication between inlet port (5) and outlet port (6) and the other (9) for controlling flow communication between outlet port (6) and drain port (7). The coaxial build-up gives short and direct channels and thus small dimensions for a given flow capacity.
