Abstract: A method of plugging a pipeline includes the steps of welding onto the exterior of the pipeline (10) first (12) and second (14) spaced apart collars, each having a sealing face (26,26A) in a plane perpendicular the pipeline (10) axis. A containment housing (34,36) is affixed by welding to the collars (12,14) to fully encompass a section of the pipeline (10) between the collars (12,14). A tapping (60) machine is then removably attached to an open top of the containment housing (34). Using the tapping machine (60) a short length of the pipeline (10) is cut and removed from between the collars (12,14) leaving two open exposed pipe ends (78,80). First and second seal elements (92,94) are positioned between the collars (12,14), Each having a forward sealing face. The seal elements (92,94) are forced apart from each other into sealing engagement with the collar sealing faces thereby closing the open, exposed ends (78,80) of the pipe (10).

Abstract: A unique golf training apparatus is disclosed in which an arm guide is secured to the off arm of a golfer. A wrist guide is pivotally attached to the arm guide and positioned on the hand of a golfers with no provision for securing same thereto. The pivotal attachment of the wrist guide to the arm guide ensures that the golfer's hand pivots properly relative to the forearm. The arm guide is generally C-shaped and extends over more than 180 degrees about a central axis, such that it firmly secures the golfer's arm to the arm guide. The golf training apparatus ensures the golfer will have his arm and hand properly positioned during the swing, eliminating "open" or "closed" swings. This results in the golfer hitting the ball more properly.

Abstract: A unique golf training apparatus is disclosed in which an arm guide is secured to the off arm of a golfer. A wrist guide is pivotally attached to the arm guide and positioned on the hand of a golfer. The pivotal attachment of the wrist guide to the arm guide ensures that the golfer's hand pivots properly relative to the forearm. The golf training apparatus ensures the golfer's arm and hand are properly positioned during the swing, eliminating "open" or "closed" swings. In one embodiment, the pivotal attachment of the arm guide to the wrist guide is through a wide integral pivot which rotates as a unit with the wrist guide. This integral pivot extends for the majority of the lateral dimension of the arm guide. This ensures that the wrist guide does not flex relative to the arm guide while pivoting, and results in the golfer hitting the ball more properly.
