Open the CIPO recordAbstract From the Canadian patent
A suspension of a starch-containing product in heated during agitation whereby the viscosity is registered as a function of the temperature. A curve over the relationship between viscosity an temperature is treated as a property profile for the sample and is compared with another known curve in order to determine the heating properties for the sample. A device for this analysis has an agitator (7), the drive means (10 11) of which has a power , sensor (12) for sensing the power which the agitator is subjected to during the agitating, whereby a measure of the viscosity is obtained. A temperature sensor (13) senses the temperature of the sample.

Why it's free to use
- Filed July 8, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 8, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 8, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
