Abstract
232,506. Davis, N. B. Oct. 23, 1924. Crystal detectors comprise a body of mercury b on which the crystal a floats, and an adjustable contact member g with a rounded or pointed end. The detector is enclosed in a glass &c. tube to which are cemented end caps d, e. The cap d is of aluminium or other metal not affected by mercury. As shown, the detector is supported by clips h secured to a panel i but it may be directly secured to the panel by bolts formed on the end caps. A spring l is provided to hold the contact member in its adjusted position.
