Open the CIPO recordAbstract From the Canadian patent
The air conditioning apparatus, particularly for rail vehicles, comprises a ventilator (1) which blows conditioned air into a distribution conduit (2). This conduit (2) permits distribution of the air in a direction (x-x') pointing both inwardly and toward the floor (P) of the vehicle, thanks to a series of openings (4) provided on the lateral surface (5) and a series of orifices (6) located facing the openings (4) on an inclined wall (6) located within the conduit (2), and behind the series of openings (4). The securement of the covering (9) on the conduit (2) is insured simply by elements having a supplemental finishing function.

Why it's free to use
- Filed January 4, 1991 and granted April 2, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 4, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 4, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
