Open the CIPO recordAbstract From the Canadian patent
A chain tension monitoring apparatus and method includes a conveyor drive having a fixed frame (27) and a floating frame (15). The floating frame (15) supports a conveyor drive unit and is biased against the fixed frame by a spring (21) to oppose forces generated by the conveyor drive operation. A force sensor (31) is mounted to the floating frame to sense chain pull applied thereto. A pre-compression load is applied to the force sensor and chain pull is monitored as a function of the pre-compression load and actual load sensed by the force sensor (31).

Why it's free to use
- Filed November 21, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 21, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 21, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
