Abstract

333,727. Evershed & Vignoles, Ltd., and Perry, C. E. Aug. 2, 1929. Thermostats. - In instruments for measuring the concentration of a solution by measuring its electrical resistance, changes of temperature are compensated by a thermostatic device which alters the dimensions of the liquid column the resistance of which is measured. For this purpose the current passes from one annular electrode 1 to two others 2, 3 and in the passages between the electrodes are arranged two insulating bodies 10, 11 connected by an insulated rod 12 on which is mounted a roller 15 carried on a. member 16 supported by a bimetallic strip 14. The member 16 is curved to such a shape that the roller 15 moves in a vertical path as the strip 14 bends. The strip 14 is carried on a pivoted member 18 which also carries a second adjustably-mounted bimetallic strip 27 bearing on the strip 14 as shown. The member 18 can be rocked by means of an eccentric pin 22 which can be adjusted from outside the apparatus. A modification having two electrodes and one movable insulating body is described.
