235. ------. [BRAUNKOHLE-BENZIN, A. G.] [Thermocouple.] German Patent Appl. B 184,414, filed Aug. 23, 1938 (Cl. IX-42 I). PB Rept. 412, May 15, 1945.

Thermocouple with the leads extending in opposite directions form the junction to avoid the problems of electrical insulation associated with parallel leads. For measuring the temperature along the center of a vertical reaction tube, the ends pass through stuffing boxes at the top and bottom of the tube so that the junction can be raised or lowered as desired.
