  • Patent number: 8522417
    Abstract: Vibration damping is important with regard to such components as hollow turbine blades in gas turbine engines. Traditionally damping has occurred through damping elements secured at the root or tip of such blades. Such damping is not optimised and results in potential problems with wear in operational life. By providing a tube of deformable material which can be located within a hollow cavity it is possible to provide an element which through friction engagement can absorb vibration energy and therefore damp such vibration. The tube incorporates a number of cuts and/or grooves in an appropriate pattern in order to define a deformation profile once the tube is expanded in location. The tube is secured in position internally upon an expandable element which is typically an inflatable device. Once in position the tube is retained in its expanded deformable profile and the engagement between the tube and the hollow cavity wall surface results in energy absorption through vibration episodes.

The small protuberances (4) are simultaneously produced in two zones spaced in the axial direction of the tubular parts (1, 2), using a tool comprising an expander with flexible blades on each of which are arranged two bosses spaced from each other in the expander axial direction. The invention is particularly useful for fixing an end sleeve (1) on a guide tube (2) of a fuel assembly.

  • Patent number: 8474131
    Abstract: A tool for joining a coupling element, such as a flange to a pipe, wherein the coupling element surrounds the pipe and has grooves facing the pipe to receive a corresponding plurality of beads provided on the pipe. The tool has a plurality of axially separated, radially movable segments. Each segment has a plurality of circle sector formed ridges. The plurality of segments thereby provides circumferentially extending ridges that are capable of deforming a pipe wall by a first pressing action on the inside wall of the pipe to create on the outside of the pipe circumferential beads in the pipe wall and to cause these beads to extend into corresponding grooves in the coupling element. The segments also have circumferentially extending portions located adjacent and between the ridges.

  • Publication number: 20130075082
    Abstract: An apparatus and method are shown for installing a metal transition end on an open end of a length of plastic pipe having an outer diameter and an inner diameter by placing a stiffener sleeve within the inner diameter of the plastic pipe at a point which is circumscribed by the metal transition end. An actuating sleeve, carried on the draw rod, allows the stiffener sleeve to be installed in a desired location within the open plastic pipe end by using the draw rod to first position the stiffener sleeve in the desired location. The metal transition end is provided with an internal relief groove which accepts any excess plastic material forced past the stiffener sleeve during the installation process.

  • Patent number: 8387436
    Abstract: An alignment device is located on a mandrel of an installation tool and is used to align a structural member in an opening of a workpiece while seating a radial flange of the structural member against a first surface of the workpiece. The alignment device comprises a disk-shaped device having an outer surface, an inner surface forming an opening through the alignment device, and where the opening is sized to be at least slightly smaller than a major diameter of an expansion portion of the mandrel. In one embodiment, the alignment is nylon to allow the inner surface of the alignment device to be repeatedly, radially expanded and yet the opening formed by the inner surface returns to its original size.

  • Patent number: 8353193
    Abstract: A mandrel assembly has a mandrel, a biasing member, and a outer member. The biasing member biasly maintains the outer member in a first position, which corresponds to a contoured portion of the mandrel, when the outer member is either on the access or the blind side of a workpiece. The biasing member is compressible to allow the outer member to move into a second position as the outer member is moved through an opening in the workpiece. In the first position, the outer member includes a maximum outer circumference that is larger than the opening of the structural workpiece. In the second position, the outer member includes a maximum outer circumference that fits within the opening of the structural workpiece.

  • Patent number: 8266782
    Abstract: A joining method for joining a second member to a first which is a tubular member having a plurality of hollow portions partitioned by a partition wall portion is provided. The first member 1 is inserted into an insertion hole 6 formed in the second member 5. A die segment 11a of a die 11 and a wedge portion segment 19a of a mandrel 18 are disposed in each hollow portion 3 of the first member 1. Next, in a state in which the partition wall portion 4 is held by and between both wedge portion segments 19a and 19a, each wedge portion segment 18a is inserted into the corresponding wedge hole portion segment 14a of the die segment 11a to thereby move each die segment 11 of the die 11 radially outward of the first member 1. With this, the inserted portion 2a of the first member 1 inserted in the insertion hole 6 and both portions 2b and 2b axially adjacent to the inserted portion are expanded to thereby join the first member 1 and the second member 5.

    Abstract: A unique tube punch forming die assembly and process is disclosed for forming a bead lock on a malleable fluid conveyance tube which provides for the attachment of a fluid connector to the tube. The fluid connector is held in the tube punch forming die constituting a die assembly where a forming groove is machined in the internal cavity of the fluid connector for forming a bead lock within the inside of the fluid connector when the punch forming die is compressed into the tube. The tube is first inserted into the punch forming die, then the die is punched to buckle the tube to form a bead lock in the tube inside the fluid connector as the end of the tube held in a cylindrical support ring. In a second embodiment a plurality of serrations are formed inside the fluid connector and the tube is forced against the serrations to improve the retention of the tube.

  • Publication number: 20120111990
    Abstract: A core adapter is provided for adapting a larger diameter core to be mounted on a winding machine designed for a smaller diameter core. The core adapter includes a cylindrical body having a wall, a central bore, an outer surface, and a discontinuity in the form of a slit extending axially along and completely through the wall. The core adapter can be inserted in an end of a core and progressively secured by expanding the body, facilitated by a widening of the slit, until the body wedges against the inside surface of the core. Adhesive can be applied to the adapter or the core or both to secure the core adapter in place. The body can be expanded with screws progressively threaded through the core and into the body of the core adapter, or vice versa. Alternatively, the body can be expanded by urging a wedge into the slit to widen the slit and consequently expand the body of the core adapter radially.
