Abstract: A thin-walled, wide mouth molded plastic container is provided with a tamper evident band initially molded as a straight-walled cylinder spaced outwardly of the lip of the container and connected thereto by a frangible horizontal bridge. The upper edge of the cylindrical band extends above the level of the container lip. Subsequent to molding and preferably before capping, the band is curled inward by application of a curling tool. The container lid is axially applied, the outer edge of the lid displacing the curled band outward. The resilience of the band and bridge permits outward deflection and immediate restoration of the curl to its initial position. The curl prevents removal of the lid without fracture of the bridge and removal of the tamper-evident band.

Abstract: In the production of a matched set of golf clubs, the most accurate method for matching the flex of each shaft in the set is through the use of an electronic frequency analyzer which measures the vibrational frequencies of the shafts or clubs. With most high quality steel shafts, such frequency measurements are generally reproducible and serve as a reliable index of shaft flexibility. It has been found for some shafts, particularly for composite shafts, that frequency measurements taken along different cross-sectional diameters may vary. For such shafts, it has been found that frequency measurements will be reproducible, if the frequency measurement is made on the same diameter. The diameters used for such measurements are marked on the shaft and then employed in the construction of the golf club, such that the diameter is substantially perpendicular to the striking face of the club head.

Abstract: Method of manufacturing a tube coupling body in a plastics material using injection moulding tooling. The body is formed with a cylindrical bore having enlarged end portions in a mould body and using removable cores. The cores form both the internal bore of the mould body and also end parts of the mould body so that once the cores are removed, end parts of the coupling body are revealed in the mould. While the end parts are still hot from the initial moulding operation, forming dies having tapering end cavities are pressed over the end parts of the moulding to form the end parts of the moulding with both external and corresponding internal tapered surfaces. The tapered internal surfaces of the end parts thus formed provide tapered cam surfaces for engaging the resilient arms of collets to be inserted in the coupling body to receive and lock tubes in the coupling body.
