  • Method for making a coiled tubing assembly
    Patent number: 9581724
    Abstract: A coiled tubing assembly includes coiled tubing having a side wall that defines an opening and an insert covering the opening and affixed to the coiled tubing. The coiled tubing has a longitudinal axis. The insert defines a capillary window therethrough. The opening and the insert include ends that are non-perpendicular to the longitudinal axis. A method of making a coiled tubing assembly includes providing coiled tubing defining a side wall opening and pulling a capillary tube into the interior of the coiled tubing through the side wall opening. The method further includes attaching the capillary tube to a capillary window of an insert for covering the side wall opening and affixing the insert to the coiled tubing.

  • Thermal ratchet system
    Patent number: 9109584
    Abstract: A thermal ratchet system includes a ratchet housing, a ratchet mandrel, a first ratchet, and a second ratchet. The first ratchet is disposed at a position generally fixed with respect to the ratchet housing and is urgeable with respect to the ratchet mandrel in an axial direction by a change in environmental temperature in a first direction. The second ratchet is disposed at a position generally fixed with respect to the ratchet housing and is urgeable with respect to the ratchet mandrel in the axial direction by a change in environmental temperature in a second direction opposite to the first direction. At least one of the first ratchet and the second ratchet is engaged with the ratchet mandrel.
