  • Patent number: 10371301
    Abstract: An elongated pipe may include a fiber reinforced polymer composite joining member for joining sections of pipe together. A pipe joint and elongated pipe may include at least two pipe sections having ends that are joined together with the joining member. The pipe joint and elongated pipe are formed by joining abutting ends of adjacent pipe sections with the joining member without the need for the adjacent pipe sections to have other connection means, such as standard bell and spigot end connections. A method may include joining pipe sections with the joining member to make an elongated pipe.

  • Patent number: 9828812
    Abstract: In a pipe joint where two pipe sections (14, 16) have threadably engaged end potions (17, 18), joint ends (32, 34) are substantially sealed to each other by a sealing surface (40, 50) on one pipe section that substantially abuts a sealing surface (42, 52) on the other pipe section. In one joint, a ring-shaped cutout(121, FIG. 7) is formed in a first pipe section and a ring-shaped spacer (120) is located in the cutout. The spacer is chosen from several that have slightly different lengths so the spacer ends contacts the corresponding sealing surface(130).

  • Publication number: 20040093077
    Abstract: A stent is constructed using interconnected links having micro-mechanical latching mechanisms. The micro-mechanical latching elements allow relative rotational movement of interconnected links in one rotational direction but restrict relative rotational movement of the two links in the opposite direction. The micro-mechanical latch surface features are formed using microelectronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction.

  • Patent number: 6679528
    Abstract: The device for quickly coupling a tube to an element comprises a tubular endpiece (1) subdivided along its axis (2) into a first portion (3) for connecting to the tube and a second portion (4) for coupling to the element (100), and fastening means (3.1, 15) for securing the tube to the endpiece and the endpiece to the element, the second portion (4) of the endpiece (1) possessing a groove (8) for receiving a sealing gasket (9). The endpiece (1) is fitted with a sleeve (10) for protecting the gasket (9), which sleeve is mounted to slide between a position in which it overlies the groove (8), thereby protecting the gasket (9), and a disengaged position which is offset relative to the groove (8).

  • Publication number: 20030218336
    Abstract: The present invention can provide a regular and unnoticeable connection since a pipe member is inserted and adhered into a joint having a diameter substantially equal to that of the pipe member. The present invention can also facilitate the connection work with low cost. The present invention can further simply couple pipe members to each other at an angle at which it is difficult to machine the pipe members and also connect complicatedly bent pipe members to each other.

  • Patent number: 6648375
    Abstract: A cylindrical thin walled tube with a through bore extending its entire axial length between first and second opposed ends is individually mounted in a bore in a fitting, with an end portion of the tube extending outward from a land surface on the fitting. A groove is formed on the exterior of the tube between the first and second ends and receives a seal element which is engageable with the land surface on the fitting. At least one mounting barb is formed on the body, generally adjacent one of the ends of the body, for fixedly mounting the tube in the bore in the fitting. The tube may also be formed with multiple mounting barbs and multiple grooves, each groove receiving a separate seal element. The outwardly extending portion of the tube acts as a male pilot for guiding the precise alignment of a bore in a complimentary fitting into alignment with the bore in the fitting in which the tube is mounted.

  • Patent number: 6620316
    Abstract: A modular system for putting together different sized filter elements, especially filter elements having different lengths, more particularly filter devices for hydraulic fluids, comprising a support tube that defines an inner cavity in the corresponding filter element, said tube being surrounded by a filter mat that is substantially cylindrical and that matches the different dimensions and having passages to let the fluid pass through. The filter elements also contain at least one coupling member enabling connection on the end side of a corresponding support tube to an additional support tube having a location on the end side for interacting with and locking on the coupling member. Each coupling member is embodied as an attachment plug element with a crown consisting of interspaced tabs extending in axial direction and hooks for snapping on the location of the attached support tube.
