Open the CIPO recordAbstract From the Canadian patent
During the cooling of high-temperature superconductor arrangements in which a polymercomposite-based electrically conducting transitional layer 3 is provided between a superconductor 1 and an electrical bypass 2, thermomechanical stresses occur in said transitional layer. To reduce these and to prevent the formation of cracks, the coefficient of thermal expansion of the transitional layer 3 is reduced. This takes place by adding a suitable filling material 32, for example particles of Si02 Al2O3 or, AIN, to the polymer composite material.

Why it's free to use
- Filed November 15, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 15, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 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.
