Open the CIPO recordAbstract From the Canadian patent
A vacuum particulate transfer apparatus is disclosed which employs a belt conveyor discharge rather than a conventional mechanical discharge auger. This handles products passing through the device more gently than prior art devices employing augers or other discharge apparatus and as such will have brought application in areas where particulate material was heretofore too fragile for handling by a vacuum transfer apparatus with a mechanical auger discharge.

Why it's free to use
- Filed October 5, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 5, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 5, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
