Abstract

2445. Zeal, G. H. Jan. 29. Alarms, fire and temperature. - Relates to a mercury thermostat which can be set to close an electric circuit at any required temperature, in order to actuate a fire-alarm or temperature regulator. The tube from the mercury bulb b is divided into two branches a and a' into one of which one terminal c<1> of the electric circuit is introduced, the other terminal c of the circuit being introduced into the bulb b. The board d on which the thermostat is mounted turns on a pivot d'. By setting this board at the required angle by means of a scale d<3> and pointer e', the mercury can be caused to make contact with c<1> at any required temperature.
