Abstract

103,848. Gethin, E. Feb. 8, 1916. Alarms operated by expansion of liquids. - A mercury thermometer, graduated in degrees and fractions in the Centigrade or Fahrenheit scale, has platinum wires fused through the stem at required temperatures and through the lower part of the stem or the bulb, which are connected in circuit with a battery and a bell, lamp, electromagnet, or other indicator. Reference has been directed by the Comptroller to Specification 5999/07.
