A drive for powering an agitator in a chemical process vessel (18) may be located inside a housing (16) attached to the vessel and may have a motor (12) that drives a shaft (14) that is attached to an agitator assembly inside the vessel. The shaft (14) may pass into the vessel through a floor (48) in the housing, which may be provided with a standpipe (50) to prevent the flow of fluid on the floor into the vessel. A shield (46) attached to the shaft may be provided above the standpipe (50) to prevent fluid from entering the standpipe from above. In addition, a sump (34, 42) may be provided to allow effective lubrication and cooling for bearings (32 40) that support the shaft.

Why it's free to use
- Filed April 28, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 28, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 28, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
