  • Patent number: 10094495
    Abstract: A pipe coupling make up assembly and a method of making up a pipe coupling between tubular sections at a well. A first tubular section in a tubular string at the well is gripped and supported in the assembly. A second tubular is supported and moved to locate a first end of the second tubular section into an expanded first end of the first tubular section. A swaged die is arranged around the first tubular section and forced along the first tubular section towards the second tubular section. This causes the expanded first end to move radially inwards under elastic and plastic deformation and create a metal to metal seal between the first ends of the first and second tubular sections.

    Abstract: An improved stent-graft device is provided that delivers a smooth flow surface over a range of operative expanded diameters by applying a unique cover material to the stent through a technique that allows the cover to become wrinkle-free prior to reaching fully deployed diameter. The unique cover material then allows the device to continue to expand to a fully deployed diameter while maintaining a smooth and coherent flow surface throughout this additional expansion. Employed with a self-expanding device, when the device is unconstrained from a compacted diameter it will self-expand up to a fully deployed diameter with the graft being substantially wrinkle-free over diameters ranging from about 30-50% to 100% of the fully deployed diameter.

  • Patent number: 8713782
    Abstract: A method, apparatus, and kit for reinforcing the distal end of a lateral in an irrigation system, typically in which the distal end of the lateral receives a head with a barbed neck. The method includes placing a crimp ring around the lateral, the crimp ring being large enough to encircle a bulge in the lateral created by insertion of the barbed neck into the end of the lateral. The crimp ring is positioned over the bulge and compressed to sheath and reinforce the bulge. The compression imparts a longitudinally convex profile upon the crimp ring, reducing its inner and outer diameters without increasing its length. This compression may cause projections, made of material from the crimp ring, to form on the outer surface of the crimp ring. A kit includes a crimp tool having a crimp die shaped to impart the longitudinally convex shape upon the crimp ring.

  • Patent number: 8631553
    Abstract: A tube splicing machine is provided which includes a frame on which a die holder is located. A swaging die is removably mounted in the die holder, and the die holder includes a main plate and a top plate that is removably connected to the main plate. A die holding opening is defined through a portion of the main plate and the top plate in which the swaging die is inserted. The swaging die includes two die parts that together define a die opening and are separable along a mid-line of the die opening. A splice fitting engagement plate with a splice fitting engagement portion is located on the frame, with the splice fitting engagement plate having an opening or an openable top to allow removable connection to a splice fitting. An actuator is connected between the splice fitting engagement plate and the die holder for moving the splice fitting engagement plate relative to the die holder from an initial position to a swaged position, in order to swage the splice fitting onto a length of hose or tubing.

  • Patent number: 8621734
    Abstract: A collet for a fastener installation tool having a pull section with a fastener engagement end and a plurality of teeth. The teeth include a first tooth with a first inner diameter, and each of the remainder of teeth includes a second inner diameter, the first inner diameter being greater than the second inner diameter. The pull section includes a protrusion extending from the fastener engagement end, thereby extending the length of the pull section. The pull section includes a cross-sectional thickness, wherein the collet is adapted to engage a pin member having a locking portion with a first diameter and a pull portion with a smaller second diameter. An increase in the difference between the first diameter of the locking portion and the second diameter of the pull portion of the pin member allows for a corresponding increase in the cross-sectional thickness of the collet, thereby extending the fatigue life of the tool.

  • Patent number: 8533925
    Abstract: An apparatus for manipulating a medical device is formed of at least three coupled movable blades which are disposed about a reference circle to form an aperture whose size may be varied. The aperture capable of being sized to contain a medical device. Each blade is in communication with an actuation device which is capable of moving the blade to alter the size of the aperture. Each blade includes a single radial point which a) lies on the circumference of the reference circle prior to movement of the blade, and b) may be moved only along a radius of the reference circle on movement of the blade.

  • Patent number: 8459917
    Abstract: A fastener for joining a first member and a second member. In one implementation the fastener includes an elastic hollow body having a proximal end, a distal end, and an axial hole. An elongate rod extends through the elastic hollow body and has a washer positioned at the proximal end of the elastic hollow body. A first head is located at a proximal end of the rod and abuts the washer while a second head is positioned on the rod so that it resides at a distal end of the elastic hollow body. The rod also includes an elongate body that extends distally to the distal end of the elastic hollow body, the rod and elastic hollow body being in non-threaded engagement with one another. The first head has a second diameter greater than the first diameter, the washer has a third diameter greater than the second diameter, the second head has a fourth diameter greater than the second diameter and smaller than the third diameter.
