Abstract: An instant coupling comprises a male element and a female element which are locked together by two teeth (19) supported by flexible strips (18), which are normally in the disengagement position but urged into the engagement position by the action of an axially slidable outer collar (12), which is itself maintained in said engagement position by annular elastic elements (20) interposed between the strips (18).

Abstract: A one-piece flange ring for mounting in an open pipe includes a flange, an outer and an inner leg projecting from the flange, and an outer and an inner annularly projecting land for engaging the inner wall of the pipe. The outer leg is closer to the inner wall of the pipe than the inner leg when installed in the pipe. The outer and the inner leg are substantially parallel to one another and a capable of being fixed under stress with respect to the flange by the inner wall of the pipe when the legs are driven into the open pipe. The outer and the inner pipe engaging lands have an outer diameter greater than the inner diameter of the pipe before installation in the pipe, and they are flexed under stress toward the center of the pipe when the flange ring is installed in the pipe. The outer and the inner pipe engaging lands have an outer diameter equal to the inner diameter of the pipe after installation in the pipe. The outer and the inner pipe engaging lands are bent diagonally toward the flange.

Abstract: A ball joint comprises a ball stud containing a ball at the leading end thereof, a socket incorporating therein a receptacle for admitting of the ball, and a resilient metallic ring containing a gap therein and adapted to retain the ball rotatably within the receptacle. The receptacle is formed of a main body and an auxiliary body adapted to be attached fast to the main body, and at least the main body is formed of a plastic material. Retention of the ball within the socket is accomplished by setting the resilient metallic ring in position within the receptacle before attachment of the auxiliary body to the main body, driving the ball into the receptacle thereby causing the equator of the ball to widen the gap in the resilient metallic ring and slide past the ring, and consequently enabling the ring to get hold of the ball.

Abstract: A guardrail terminal for use at the upstream end of a conventional guardrail consisting of a plurality of joined together horizontally extending W-beam guardrails which are layered in a curve away from the traffic side of the guardrail in an upstream direction. An eccentric lever is connected to the upstream end of the terminal for introducing a bending moment on the terminal whereby an impacting vehicle at the upstream end will facilitate buckling of the rails and allow the vehicle to pass behind the terminal instead of being speared or spun around by an end on impact. The rails are supported by break-away supports and the rails are secured to only the first upstream vertical support but are laterally movable relative to the other vertical supports. The lever includes a metal beam connected perpendicular to the upstream end and extends away from the traffic side and a tubular member encloses the first support, the metal beam and the end of the upstream rail.

Cooperating with the first cylindrical member is a second cylindrical member having an axial opening sized to accommodate the first cylindrical member and an inside surface groove having a second surface of revolution disposed at an angle with the axis of the second cylindrical member. A continuous ellipsoidal spring having canted coils is disposed in both first and second cylindrical member grooves for forcing the first and second surfaces of revolution away from one another to cause axial loading between the first and second cylindrical members. Additional locking surfaces may be provided each of the first and second grooves which are disposed generally perpendicular to the first and second cylindrical member axis.

A cam is pivotly mounted on a trunnion connected to the stationary clamping surface has a spiral clamping surface, the stationary clamping surface and spiral clamping surface being positioned to constitute a clamping means when the clamp is in a clamping position. A spring means having one end connected to the trunnion and the other end connected to the cam is provided for biasing the cam to the clamping position. A lever pivotly mounted on the trunnion has a projection which engages the cam and causing it to pivot with the lever when the lever is pivoted to a clamp releasing position. The cam preferably has two spiral surfaces, one generated by a line parallel to the axis of rotation of the cam and the second cam surface by a line forming an angle with the axis of rotation of the cam.

Abstract: A sealing device is disclosed for sealing a securing device (17) which extends through adjacent flanges (7,9) of a shell (1) and of a head (3) of a fluid container. The sealing device includes an O-ring seal (23) which slidingly engages the securing device (17) for sealing the securing device relative to the flange (9) of the head. A carrier member (25) through which the securing device extends is urged towards the flange (9) of the head such that the O-ring seal (23) is urged into sealing engagement between the securing device (17) and the flange (9) of the head. The carrier member (25) defines a conical recess (35) for reception therein of the O-ring seal (23) such that when the carrier member (25) is urged towards the flange (9) of the head, the O-ring seal (23) is distorted by reaction between the carrier member (25), the securing device (17) and the flange (9) of the head so the securing device (17) and the flange (9) of the head are sealed relative to each other.

The arrangement also includes means for supporting the two line sections in their coaxial and unconnected relationship with one another and a tubular sealing member disposed coaxially within the line and across the axial joint between and directly against the adjacent sections and joint for internally sealing the joint while allowing fluid within the line to pass from one of the sections to the other.

Abstract: The invention relates to a method and apparatus for remotely connecting or disconnecting upper flexible choke/kill lines (including auxiliary lines) to choke/kill lines of a floating drilling rig riser which has been lowered toward the sea floor. Remote stab assemblies are mounted to a stowable tension ring releasably secured to a housing secured to rig beams. In the stowed position, hydraulic stab connectors secured to travelling yoke assemblies are disconnected from each line.
