Open the CIPO recordAbstract From the Canadian patent
An apparatus for detecting a temperature by means of at least one temmerature-responsive sensing resistor (F1,F2) comprise an evaluating circuit which processes a voltage drop depending on the temperature of the sensing resistor. The sensing resistor (F1,F2) lies at a common current source (1) in series with two fixed calibration resistors (G, D). The basic resistor (G) has a lower calibration value (Rel) which is assumed by the sensing resistor at a predetermined lower temperature. The differential resistor (D) has a differential calibration value (Rd) of such a size that the series circuit of the calibration resistors has an upper calibration value (Re2) which the sensing resistor assume …

Listed from its CIPO record in Patent Yard's archive of Canadian patents past their term. Its claims, description and drawings are in the CIPO record and on Google Patents, and the Claude kit works from them.
Why it's free to use
- Granted November 4, 1986. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended November 4, 2003.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
