Open the CIPO recordAbstract From the Canadian patent
A series of closely packed thermocouples formed into a torus (60) are held in compression against the Lorentz Force by a dielectrically insulated tie strap (61). High current circulates through the torus (60) due to reduced electrical path length effected by low-thermal-conductivity elements (64) and grooves (38) formed in hot and cold fins (66 and 65). Reduced heat transfer between hot and cold fins (66 and 65) generates higher circulating current. Thermoelectric junctions formed between the hot and cold fins (66 and 65) and the low-thermal-conductivity elements (64) are preferably established by coated layer(s) (67) of dissimilar materials including bismuth constantan, nickel, …

Why it's free to use
- Filed May 9, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 9, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 9, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
