Open the CIPO recordAbstract From the Canadian patent
A replacement flange for the end of a catalytic converter is provided by a pair of generally L-shaped coupling elements which have their base portions opposed and seated in an elongated channel element which permits one coupling element to slide therein relative to the other. The opposed edges of the flange coupling elements are generally arcuate to fit about the end pipe of the converter and have recesses to seat the flanges on the sides of the converter body. Assembly is effected by mounting one coupling element to the automobile support structure about the converter end and then sliding the other coupling element sideways into engagement therewith and mounting it to the support structure.

Why it's free to use
- Filed April 9, 1990 and granted April 6, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 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.
