Open the CIPO recordAbstract From the Canadian patent
The invention concerns an anti-deflagration device for a hydrogen recombining unit comprising filters (8) and (9) at the input and at the output of a convection container (5) containing plates (6) coated with a catalytic coating. Said filters (8) and (9) generate a pressure drop which prevents the sudden occurrence of a large amount of gas in the recombining unit and confine inside the container (5) the particles which are released from the catalytic coating thereby reducing the risks of deflagration.

Why it's free to use
- Filed August 17, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 17, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 17, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
