Abstract

233,782. British Thomson-Houston Co., Ltd., and Boyd, W. F. Feb. 14, 1924. Crystal detectors are provided with a contact wire which is permanently in contact with the crystal rotation of which alters the point of contact. As shown the contact wire a is helical so that rotation of the wire moves the point of contact over the crystal. In a modification the contact wire is in the form of a ring and is carried by a threaded stem so as to be moved across the crvstal when rotated. In a further modification the rotation of the wire. is made to move the crystal. According to the Provisional Specification an insulated guard member may be provided to prevent the contact wire leaving the crystal.
