The fingers are expandable from the first arrangement to a second arrangement having a diameter greater than the diameter of the aperture. A spreader pin resides within the bore and within the fingers. The spreader pin is movable from a first position with the fingers at the first arrangement to a second position within the fingers to a second arrangement with the finger engaging surface in communication with the fingers. A handle, pivotally connected to the base member by a pivot; has an impact end which drives the spreader pin into the fingers upon rotation of the handle.

Abstract: Two components (2, 3) to be joined to each other by vibration welding form on one or both sides of the bounding seam (10) barrier means (20) including a labyrinth seal. Means (20) retaining attrition particles of the jointing faces (16, 17) in chambers (25, 26, 27) by the attrition particles needing to migrate from chamber to chamber through damming gaps (21, 22) and to be deflected for passage through the next gap in each case. Due to this tortuous arrangement the attrition particles remain totally within the chamber system of the labyrinth seal (20) and do not emerge from between the flanges (8, 9). When the seal (20) is provided between the seam (10) and the inner face (6) of a container, the interior thereof is thus protected from soilage due to attrition particles.

Abstract: A novel apparatus and method for attaching a rounded member, such as an inflator assembly for an automobile air bag, to another member or surface, particularly a flat surface, is disclosed. A spacer, which may take the form of a split ring, is positioned around an attachment surface of the rounded member. Then, while the spacer is supported against further motion along the inflator, a flange having a shank with a tapered inside diameter may be passed around the inflator and spacer. As the inside diameter of the flange narrows to contact the spacer, the flange exerts inward pressure tending to frictionally engage the inflator with the spacer, and the spacer with the flange. Thus, an interference fit having a high retention strength may be comparatively easily and rapidly formed. The spacer may be hardened so as to indent the inflator and/or the flange to enhance the retention strength of the assembly.

Abstract: A cable bolt comprises a cable with a tubular yielding fixture at one of its ends. The pull-off load of such yielding fixture can be adjusted to a desired value. This is achieved by unwinding one end of the cable and inserting a slug over the kingwire. Then, the peripheral wires are wound again over the kingwire forming a bulge in the cable where the slug is located. The yielding fixture is then slid on the cable and forced over the bulged portion of the cable, while measuring the load required to achieve this operation, which also becomes the pull-off load of the yielding fixture. Finally, any part of the cable protruding from the fixture is cut-off to form the cable bolt with the desired yielding fixture at its end.
