Abstract

13,852. Marconi's Wireless Telegraph Co., and Ewen, H. A. Sept. 29. [Cognate Applications, 3233116 and 3789/16.] Thermal switches.-A relay comprises a switch arm A mounted so as to be rotatable only in one plane, under the opposing actions of a controlling- force and one or more stretched filaments E arranged nearly parallel to the axis and connected to a support G. The two filaments may cross at a short distance apart, and are traversed by the current to be relayed. An adjustable weight L on the switch arm provides the controlling-force. The support G is hinged to a frame J towards which it is drawn, for purpose, of adjustment, by a stiff spring K. According to the Provisional Specifications 3233/16 and 3789/16, sensitiveness may be increased by enclosing the device in a vacuum.
