  • Patent number: 9193468
    Abstract: An assembly to hold an interface of a stationary outer structure of a nacelle and a casing of a jet engine includes first and second raised elements and two half rings. The first raised element belongs to an upstream end of the stationary outer structure, and the second raised element belongs to a downstream end of the casing. The first and second raised elements are formed so as to be placed in contact with each other, and the two half-rings are formed by a wall and an abutment. The wall defines a housing to receive the first and second raised elements when the casing and the stationary outer structure are mounted edge to edge, and the abutment is formed so as to keep the first and second raised elements in the housing.

  • Patent number: 8491017
    Abstract: An engagement section of a holder is engaged with a metal gasket, the gasket is received in a tubular section, and the tubular section is fitted in a step of a connection pipe. Another connection pipe is placed close to and facing the connection pipe that holds the gasket through the holder, and a center ring is installed surrounding the outer peripheries of the flanges. While a trapezoidal section having slopes which define both sides is inserted into a groove, center ring segments are closed to form a ring shape. A bolt which penetrates through a cutout of a segment is screwed into a threaded hole of the segment. The screwing of the bolt causes the amount of insertion of the trapezoidal section, which has slopes which define both sides, into the groove to be increased. As a result, the distance between flanges is reduced and the contact pressure of projections against both sides of the gasket is increased.

The segments are formed from sub-sections connected to one another end-to-end. Each sub-section has a surface region disposed to engage the outer surfaces of the pipe elements. Each surface region has a different radius of curvature from a surface region on a neighboring sub-section. The radii are selected so that when the coupling segments are deformed around the pipe elements, portions of surface regions of selected sub-sections contact the pipe elements, while portions of surface regions of those sub-sections between the selected portions remain in spaced relation away from the pipe elements. A constant and minimal torque is required to bolt the segments together as a result.

  • Patent number: 7425023
    Abstract: A profiled clamp with at least one profiled segment which extend successively in the circumferential direction of the clamp and are clamped by means of at least one clamping device. The profiled segments have a profile which in cross-section is essentially inversely trough-shaped or cup-shaped. When the clamp is clamped, flanges which are provided at the ends of two pipes to be connected by the clamp are pressed toward each other between diverging side walls of the profiled segments. Gaps with a bottom each are provided between adjacent profiled segments. In each gap is provided a resilient metal strip at a distance from the bottom of the gap which is greater than the thickness of the bottom of the profiled segments, wherein the metal strip extends transversely of the plane of the clamp, and wherein the metal strip is mounted through lateral arms of the metal strip at the bottom of the gap.

  • Patent number: 7104572
    Abstract: Plural spaced projections attached to the outer surface of a branch pipe of a tapping sleeve positioned on a main water line are disposed in contact with a rubber gasket also positioned on and disposed about the branch pipe. A two-piece split gland is also positioned about the branch pipe and engages a first surface of each of the projections. The split gland is adapted for coupling to the flange of a mechanical joint tapping valve by plural nut and bolt combinations for urging the gasket into intimate contact with a second opposed surface of each of the projections and the tapping sleeve's mechanical joint in forming a seal with the branch pipe. The split gland coupling allows for vertically orienting the tapping sleeve even when the main water line is not level, or horizontal, to facilitate tapping valve access via an extension pipe when the tapping sleeve is buried.

  • Patent number: 6536811
    Abstract: A pipe coupling includes mating hub sections engaged by outer split clamp elements that are compressed together against mating tapered surfaces of the hub sections to draw the hub sections together into tight fitting relationship. The clamp elements are driven into a compressed condition by an outer locking ring that fits over the split clamp elements to draw the hub sections together and to retain the hub sections against axial separation. The clamp elements have locking surfaces engageable by the locking ring and axial movement of the locking ring is limited by appropriate stop surfaces and retainers. A locking sleeve installation and removal tool utilizing an actuator system is described.

  • Patent number: RE45304
    Abstract: A coupling for securing pipe elements together in end-to-end relation has segments joined end-to-end by adjustable connection members. The segments surround a central space which receives the pipe elements. One or more gripping bodies are captured between the segments. The gripping bodies are arranged opposite to each other. The segments have angularly oriented reaction surfaces on the connection members. The gripping bodies have angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping bodies radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping bodies engage and retain the pipe elements.
