<p>PCT No. PCT/GB94/00097 Sec. 371 Date Jul. 19, 1995 Sec. 102(e) Date Jul. 19, 1995 PCT Filed Jan. 19, 1994 PCT Pub. No. WO94/16874 PCT Pub. Date Aug. 4, 1994A resiliently flexible ring of dimensionally heat-recoverable polymeric material whose tubular length is less than its notional circular diameter, formed so that it inherently maintains a non-circular open configuration enabling it to grip resiliently an object around which it is placed in use prior to heat-recovery, the maximum transverse dimension of the said object being at least 2.5% less, preferably at least 5% less, than the notional circular diameter of the ring. The ring preferably has at least three "corners" of relatively small radius of curvature, preferably evenly spaced around its circumference. Use of the rings is described for damping the noise of chain-drive sprocket wheels and for connecting flexible hoses to supply outlets.</p> |
