Abstract: A freestanding room divider comprising a first panel comprising a first top, a first bottom, a first right side, a first left side; a second panel comprising a second top, a second bottom, a second right side, a second left side; a first rail attached to the first bottom; a second rail attached to the second bottom; a first panel first brace and a first panel second brace for engaging the first rail, and a second panel first brace and a second panel second brace for engaging the second rail and wherein first and second braces each further comprises at least one vertical member attached to at least one horizontal member; a first pin and a second pin disposed on the first top; and a third pin and a fourth pin disposed on the second top; and a bar having a first end and second end wherein the first end engages the second pin and the second end engages the third pin connecting the panels.

Abstract: In the present invention there is provided, a pipe connector for use in tendons, risers or other pipe connections. The pipe connector comprises a tubular pin member and a tubular box member. The tubular pin member has a frusto-conical outer peripheral surface, an inner axial end and outer axial end. The tubular box member is telescopically engageable with the pin member and has a frusto-conical inner peripheral surface that further has an inner axial end and an outer axial end. The frusto-conical inner peripheral surface of the tubular box member corresponds to the frusto-conical surface of the pin member and overlies the frusto-conical surface of the pin member when the members are engaged. There is provided annular projection and groove means in the frusto-conical surfaces of the pin member and the box member that interengageable to axially lock the pin member and the box member together. A system for assembling tension-leg pipes using the claimed connector is also provided.

Abstract: An offshore marine structure for drilling wells into the ocean floor including a floating vessel which carries the necessary drilling equipment. A riser which extends from the vessel to a well head at the ocean floor, encloses a drill string and permits circulation of the drilling mud and fluids. The riser is comprised of at least two detachably connectable segments, one of which can be moved with the floating vessel, while the other remains buoyantly in place until such time as the two segments are reconnected. A riser system used for production activities where the riser comprises at least two detachable segments is also provided.

Abstract: A connector comprises a first coupling assembly comprising a first coupling member associated with an annular body from which extend a plurality of radially flexible fingers provided at their ends with engagement ribs engageable in grooves in a second coupling member to be abutted against the first coupling member. The fingers are held in their radially inner engaged position by a locking ring axially movable relative to the annular body between a locking position and an inoperative position. The locking ring may be associated a disengagement portion which, as the locking ring moves to its inoperative position, engages the ends of the fingers to move them radially outwardly to disengage the ribs from the grooves. The annular body may be axially movable relative to the first coupling member or fixed relative thereto.
