Abstract: A fitting for a fluid conduit includes a coupling body, a coupling nut, a conduit gripping device that is axially driven by the coupling body and the coupling nut to provide grip and seal against a conduit, and a strain sensor unit disposed on a neck portion of the coupling body, the strain sensor unit including at least a first axially extending strain sensor positioned and oriented for strain sensor unit measurement of a first strain of the neck portion corresponding with a first fitting assembly condition, and a second strain of the neck portion corresponding with a second fitting assembly condition different from the first fitting assembly condition.

Abstract: In an exemplary method for installing a fitting on a conduit, a fitting body is provided with a threaded end portion, a neck portion extending rearward from the threaded end portion, and an internal conduit socket extending axially into the neck portion and terminating at a counterbore. A conduit is inserted in the internal conduit socket of the fitting body. A fitting nut is pulled up on the fitting body to grip and seal a conduit gripping device against the conduit. Relative axial displacement of at least first and second reference locations on the neck portion is detected to determine whether the fitting is in a first fitting assembly condition or a second fitting assembly condition different from the first fitting assembly condition.

Abstract: A shoe shine box has a base defining an inclined opening and a lid closing the opening. A shoe rest is attached to one side of the lid, the shoe rest having an inclined shoe support surface. A shoe clamp is attached to the shoe rest to hold the shoe against the shoe rest for polishing. The lid is movable between a first position closing the lid with the shoe rest in the box and a second position closing the lid with the shoe rest outside the box. The shoe support surface can be in positioned in either an inclined polishing position or a level polishing position when the lid is placed in the second position to provide a multi-function shoe polishing station.
