Open the CIPO recordAbstract From the Canadian patent
A system (10) for pumping or mixing a fluid using a levitating rotating , magnetic bearing (14) and various other components for use in a pumping or mixing system are disclosed. The magnetic bearing (14) is placed in a fluidcontaining vessel (16) in close proximity to a superconducting element (16). A separate cooling source (24) thermally linked to the superconducting element provides the necessary cooling to induce levitation in the magnetic bearing. The superconducting element (20) may be thermally isolated such that the , bearing, the vessel, and any fluid contained therein are not exposed to the cold temperatures required to produce the desired superconductive effects and the …

Why it's free to use
- Filed January 12, 2001 and granted March 22, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 12, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 12, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
