The frame (17) is pivotally suspended from two U-shaped rods (19) and is horizontal in the position of equilibrium. The frame (17) can be pivoted from the position of equilibrium to an inclined discharge position.

Why it's free to use
- Filed August 31, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 31, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 31, 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.
