(WO9522091-A1)      Process for attaining specific temp. behaviour from temp.-dependent controllers for valves or thermostats, which have an operating device opened by the pressure in a pressure chamber, involves (a) producing a zeotropic mixt. of at least 2 substances; (b) filling the pressure chamber with the mixt.; and (c) adjusting the mixing ratio according to the desired temp. behaviour.    ADVANTAGE -   Hazards are reduced drastically, as the mixt. can be prepd. without using toxic cpds. or those which are hazardous to the environment, which also eliminates the need for disposal as special waste. Output signals can be obtd. at temps. which cannot be achieved with pure substances.
