thermometrical arm

An instrument to release an alarm when a dangerous heat is reached in an apartment; a form of fire-alarm. One form consists of a bent gla tube with a bulb at each end, one of which with a part of the stem contains ether; the other with a part of the stem containing mer cury and open to the external air. The tube is poised on its center by gravity. Should the temperature be raised by the presence of fire, the ether would be expanded, the mercury driven into the bulb, the instrument tipped over on its axis, and the alarm sounded. thermometric-analysis, 8. Chem.: Applied to certain approximate methods of analysis, depending on the observation of the temperature when a phenomenon takes place, or of the changes of temperature accompanying chemical reactions-e. g., fixed oils evolve different degrees of heat when treated with strong sulphuric acid, and the temperatures thus produced are used to determine the proportions of two in a mixture, or to identify two oils, especially when one is a nondrying and the other a drying oil. When 15 grms. were treated with 7.5 grms. sulphuric acid of 90 per cont., the following rise of temperature was observed in the three oils tested: olive-oil from 12-40%, rape-oil from 17-54°, and linseed oil from 16-91.
