An apparatus for conveying materials behaving substantially as fluids through ducts comprises a cable having a plurality of radially protruding interspaced elements moulded in such a way as to each incorporate the protruding ends of a rivet radially passing through the cable so as to act, in cooperation with the swelling in the cable due to the penetration of the rivet as a means, for preventing the elements from sliding along the cable. The moulded elements are also provided at the point of, incorporation of the cable with tapered extensions so as, to avoid sharp variations in the rigidity of the cable which could give rise to fatigue failure.

Why it's free to use
- Filed March 29, 1990 and granted January 7, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 29, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 29, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
