An expandable slip ring is used to secure attachment of an expanded tubular to a surrounding tubular. It features elongated generally axially oriented openings separated by narrow segments. As a swage is advanced within a tubular that has the slip ring outside it the narrow segments or tabs expand and can break but the ring is still held to its shape as the expansion progresses due to the integrity of other tabs that can subsequently break as the swage advances within the tubular that is surrounded by the slip ring. The integrity of the slip ring is enhanced for storage and run in while the expansion characteristics are more uniform as the ring retains some structural integrity during much of the expansion process.

A Powered Lower Bobbin Feed (“PLBF”) system is disclosed for improving the operation of deflector type rotary braiding machines, such as the Wardwell Rapid Braider. The PLBF eliminates or reduces the impulsive tension spikes set up by the deflection and feed process in current rotary braiding machines by uniquely controlling the lower bobbin filament feed. These tension spikes result from: the rapid rotational acceleration and deceleration required of the lower bobbin as a result of the feed process; the lever arm tension control and bobbin ratchet mechanism; and the shape of the filament deflector surface. Such failure limits the operating speed of rotary braiding machines, the minimum size of filament that can be braided effectively, or the ability to maintain the quality of the braid produced. By eliminating or reducing these spikes, the PLBF therefore can increase the working speed of circular braiding machines and improve the uniformity of braided filaments generated by such machines at a given speed. In the preferred embodiment, the PLBF comprises: a slip ring designed to provide power to the lower bobbins; a variable speed powered lower bobbin concept; a feedback control system for the bobbins to assure bobbin feed matches braid consumption; and an improved, more contoured, deflector surface to minimize feed tension spikes. The new contour can be created: by retrofitting existing deflectors with a spline; or, by making new deflectors that incorporate the overall contour of a retrofitted deflector.
