Abstract

8759. Baptifaut, A., and Sydenham, H. J. April 10, 1908, [Convention date]. Void. [Published under Section 91 of the Act.] Alarms operated by expansion and evaporation of liquids.-A curved copper tube A of oval cross-section is filled with a volatile liquid, such as alcohol, ether, or petroleum, and is fixed at one end A' to the base of the apparatus, its other end being connected by a chain C to a drum B, which is rotated against the action of a spring K when the tube A is acted upon by heat. A needle D, which is clamped by a screw to the spindle F of the drum B and is counter-weighted at I, is thus moved into contact with an adjustable contact-stop G, thereby closing an electric circuit comprising wires attached to terminals M, N.
