Open the CIPO recordAbstract From the Canadian patent
Horizontal, small diameter cyclones are disclosed. Gas and fines are introduced via an inlet (310) tangentially around a clean vapor outlet tube (314) in a cylindrical cyclone (300). A vortex of solids and some gas pass into a contiguous and axially aligned cylindrical vortex containment body (410) from which solids are withdrawn via a horizontal slot (460). Removal of particles <5micrometers is enhanced. An FCC process uses the cyclones as a third stage separator. An alternative design uses a half pipe extension (430) on the solids' outlet to confine the vortex of solids and gas.

Why it's free to use
- Filed April 26, 1995 and granted January 11, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 26, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 26, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
