Abstract: A clamping device for connecting a branchpipe to a main pipe buried underground, has a main body with a lower side having a curved surface for engaging the main pipe and, at the same time, is provided with a connection port for a branched coupling. Arms are supported by sections of the body on both sides of the connection port cand on the upper side of the main body. These arms are extended downwardly so as to hold the main pipe and move for free rotation with respect to the support sections. Arm retainers are idly supported at the centers by bolts which are screwed into threaded holes provided on a midplane of the support sections of the main body. The retainers have pushing sections formed on both their ends for pushing the arms from above, at external sides of the support sections. Only a small working hole must be excavated for connecting the branched pipe to the main pipe since the clamping device can be positioned and tightened from ground level.

Abstract: A metal to composite tubular joint includes an inner metal sleeve over which is mounted a composite tube made from a plurality of fiber layers. An axial load transfer assembly made of a plurality of metal members is mounted around the composite tube. One end of the joint is threaded for detachably coupling the joint to another structural element such as a pipe or a further joint.

Abstract: This safety barrier comprising a frame and two stands is obtained by bending a tube for forming the lateral uprights and the handrail as well as two first legs of the stands, and by fixing the bottom rail consisting of another tube bent at both ends for forming the legs complementary to the first legs. The angle of divergence and/or the length of one pair of legs forming a first stand differ from those of the other pair of legs forming the other stand of the barrier. The invention is applicable to the iron-work industry in general.

Abstract: An aircraft duct gimbaled joint is disclosed which permits the ducting to be deflected when high pressure--high temperature gases, vibration and gravitational forces upon take off and during vertical climbs cause substantial expansion and movement. The gimbaled joint comprises two spaced apart end rings, each formed with a pair of perpendicular protruding lobes which are inserted into slots formed in the end face of a center ring. The protruding lobes of the end rings are pivotally connected to the center ring by pivot pins which are doubly supported by the inner and outer walls of the center ring. The lobes of the first end ring are rotated 90 degrees relative to the second end ring providing movement about a vertical and horizontal axis. The rings are sealed by a flexible bellows which fit over and enclose the center ring.

Abstract: In a sea, lake or other body of water, sedimentation of sedimentary solid material may be obtained in desired areas by reducing the hydraulic pressure in the sea floor or lake bottom layer in the respective area. Such reduction of the hydraulic pressure causes water to flow from the lake or sea into the porous bottom or floor layer whereby material suspended in the water or transported along the bed settles on the floor or bottom. The reduction of the hydraulic pressure is obtained by pumping water from underground drain tubes or other drainage devices extending along and adjacent to the coastline. The method may be used for coast protection and reclamation of land.

Abstract: A pipe joint is restrained against axial separation by the use of a bearing ring. Various embodiments of bearing rings having wedging surfaces cause an increase in the resistance to pipe separation as the joint separating thrust increases. That is, as the force tending to cause pipe separation increases, the wedging surface on the bearing ring cooperates with a corresponding wedging surface on a spigot ring to increase the resistance of the pipe joint to separation. The spigot rings are connected to the spigots by welding, set screws, heat-shrinking, etc.A specially shaped snap ring or bearing ring and associated method of making the bearing ring is used to avoid possible problems resulting from manufacturing tolerances. Specifically, the bearing ring is constructed with a major diameter greater than diameters at other locations on the ring.

Abstract: A seabed mound creating method suitable for a construction of a large scale offshore structure comprises the steps of setting up a plurality of sheet piles along the outer periphery of a mound creation region in a seabed area of soft ground to form an earth-retaining wall projecting from the seabed, and raising the ground level of the seabed within the earth-retaining wall by depositing soft soil into the earth-retaining wall to heap the deposited soil to a predetermined height. The method further comprises the step of implementing a ground improvement process to both the heaped-up soft soil and the soft ground of the seabed within the earth-retaining wall so that the ground improvement process is provided to a predetermined depth below the seabed, thus to form a seabed mound integral with the improved ground. The seabed mound may be provided at the upper portion with a projection area serving as a shear key with respect to a horizontal external force.
