Open the CIPO recordAbstract From the Canadian patent
The present invention provides a system and method for monitoring the integrity of a furnace containing molten material and giving a prior warning of a potential breakout or process equipment condition using multivariate statistical tools. Multiple multivariate models are used in combination to provide status of the process and deal with long term process drift. The various model results are then used in conjunction to arrive at a conclusion which indicates the system allows for automatic halting of the process in order to prevent a catastrophic failure of furnace integrity.

Why it's free to use
- Filed June 4, 2004 and granted September 17, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 4, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 4, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
