Abstract
273,764. Cheneau, L. J. J. B. July 3, 1926, [Convention date]. Thermostats.-An alarm of the kind operated by the pressure of an expanding fluid on a diaphragm comprises-an outer cylinder 2 of good heat conductivity and an inner cylinder 1 of inferior conductivity. The cylinders are closed at one end by a disc 3 carrying an electric terminal 16 and at the other by a disc 4 carrying an adjustable screw terminal 8. Within the cylinder 1 is a corrugated copper diaphragm 6 normally in contact with the screw 8. On slow heating no action occurs, but on rapid heating the air between the cylinders expands and exerts pressure on the diaphragm by way of small apertures 5, breaking the circuit to give an alarm. In a modification, the air space between the cylinders is constituted by a series of small tubes, and the diaphragm is replaced by a spring-pressed piston. In another modification, Fig. 4, in which a piston 6 is used, the annular air space 2 communicates bv a tube 5 with a chamber 7 in front of the piston. The contact screw 8 is in connection with a terminal 8<1> through a cap 13 and plug 12 mounted in an insulating disc 4. The terminals 8', 16 are carried by end stays 14 and the apparatus is protected by a perforated casing 15.
