Abstract: In one embodiment of the invention, there is provided a tubular assembly having a lateral connection. The assembly comprises a spool body, a carrier ring, penetrators, and an urging means.The carrier ring is built to carry the radial penetrator(s) for the carrier body. The carrier ring is mounted in sliding relationship, concentric with the carrier body. The ring is spring loaded down relative to the carrier body, against a stop shoulder (device) there. This fixes or at least stabilizes the ring on the body during running into the spool body or retrieving from the spool body.The carrier ring fits into the spool body and seats on a stop in the spool body. The carrier body also seats in the spool body, but on a different stop.Radially extending penetrators are mounted in radial ports or passages in the carrier ring, and are fixed to control fluid lines which conduct the fluid down into the well. The penetrators can move radially relative to the ring, but not axially.

Abstract: A coupling device for releasable and sealing connection to a tubular, externally threaded connector part. The device includes internally threaded segments which can swing radially to enable the coupling device to be connected to and released from the connector part. An axially movable sleeve is mounted concentrically around the segments and can be moved over the segments between a forward position in which the sleeve brings the threaded segments into meshing engagement with the threads of the connector part, and a rear position in which the segments are able to swing out so as to release the engagement. The segments and the sleeve also include mutually coacting means which, when in engagement with one another, limit the possibility of relative rotational movement in one direction between the segments and the sleeve.

Abstract: A hose-coupler made up of a just one component having a main housing section with a female end and a male end. The second female end of the coupler is formed with interior threads, for receiving therein a portion of the male end of the second hose. The main housing section has a compressible portion adjacent to the first male end thereof all the way to the end of the female end. The compressible portion is provided by a plurality of circumferentially spaced-apart linear slots for forming a plurality of clamping jaws or elements, so that, when these clamping jaws are compressed toward each other, the interior threads of the female end of the coupler is forced into locking, threaded engagement with the exterior threads of the male end of the second hose telescopingly received therein. In order to compress the clamping jaws, there is provided a collet rotatably-mounted about the main housing's compressible section.

Abstract: A threaded fastener has a casing enclosing at least three radially inwardly biased arcuate segments positioned to engage the threads of a bolt or hollow threaded member. The casing defines spaced apart internal frustoconical surfaces positioned to engage corresponding surfaces of the segments in the same axial direction. The radially inner ends of the frustoconical surfaces are directed toward a first end of the fastener, and the diameter of the radially inner end of the frustoconical surface away from the first end of the fastener is less than the radially outer diameter of the other frustoconical surface. The threads of the segments substantially fully engage the threads of the bolt or hollow threaded member.

Abstract: A tubular connector joint has a pin member on one of the tubular members and a box member on the other of the tubular members. External pin threads are formed on the exterior of the pin member. Internal box threads have the same pitch as the pin threads. A latch ring locates between the pin threads and box threads. The latch ring contracts and has threads on its inner and outer diameter that mate with the threads of the two tubular members. A drive key causes the latch ring to rotate with the pin member. The latch ring contracts when the upper tubular member stabs into the lower tubular member. A short amount of rotation then causes the drive ring to engage the threads of the lower tubular member.

Abstract: A connector system for joining a male tube to a female tube comprises an axially-split nut which extends across the region being joined. The female tube is externally threaded and mates with internal threads on one end of the axially-split nut. A shoulder formed in the other end of the axially-split nut engages a retaining ring formed on the male tube. A compressible seal ring is disposed between the end of the female tube and a second shoulder of the retaining ring. An external nut is placed over the axially-split nut to hold the entire assembly together and provide a radially compressive force on the seal ring. An axially compressive force can be provided by turning the female tube to draw the female and male tubes closer together.

Abstract: A coupling apparatus is provided for quick coupling of surface pumping equipment to a cylindrical member. The cylindrical member is engaged by dogs which are urged into locking position about the cylindrical member.

Abstract: Connector for quick release under load, particularly for pipes for transporting fluids such as hydrocarbons, characterized by the fact that it comprises, between two opposite structural elements (1, 2) or between two parts of an element connecting the two structural elements, at least a connecting device comprising an internally shaped annular ring (7) consisting of at least two segments of complementary shape, a rod (4) equipped with an outside shaping corresponding to the inside shaping of the ring, engaged internally in said ring and extending over at least a part of its height and an annular sleeve (6) engaged on said nut and able to be moved axially in relation to it under the effect of an actuating element, such as a cylinder (12) acting directly or indirectly on said sleeve.

Abstract: A telescopic connector which may be varied in length and a method for installing the connector is disclosed. The connector includes telescoping male and female members which are joined by the action of a spring, which functions as a lockring, positioned in recesses in the two members. The spring possesses at least one release finger at one of its ends, the release fingers extending through an opening in the female member. The recess in the female member includes a shoulder portion and at least one cam surface. The recess on the male member may be either a recess comprising a shoulder portion and cam surface or a recess created between threads on the outer periphery of the male member. The cam surfaces restrict movement between the telescoping members until such time as the release fingers are manipulated to expand the spring, causing the spring to position within the shoulder of the female member, providing clearance between the spring and the male member which allows for two-way movement.

Abstract: A wellhead connector comprises a tubular main body movably mounting a set of circumferentially spaced members for radial extension and retraction. An actuator on the main body is operatively associated with the members to radially extend them. Levers are interengaged between the main body and the members, when the latter are extended, and are operative to at least partially retract the members.

Abstract: A faucet connector includes a nut assembly having a pair of individual sections that form a bore for receiving a pipe-like member, such as the tailpiece of a faucet assembly. A retaining device including a pair of strap-like members surround the nut sections to maintain the nut sections in surrounding relation with the tailpiece.The nut sections are free to move radially toward and away from each other and therefore into and out of contact with the tailpiece. A pair of levers are pivotally connected to the retaining device and are operable to pivot into and out of contact with the nut sections respectively. Pivoting the levers to contact the nut sections urges the nut sections into clamping engagement with the tailpiece. By wedging the upper ends of the levers into contact with the supporting structure on which the faucet assembly is positioned, a downward force is applied to the tailpiece through the nut sections to clamp the faucet assembly onto the supporting structure.
