Abstract
240,714. Eckersley, J. P. Feb. 20, 1925. Crystal detectors.-A crystal detector comprises two crystals or a crystal and catwhisker mounted in open slots in ebonite crossbars 8 held apart by springs mounted on guide rods 3. A rod 6 serves to rotate crystal 4 while a screw serves to adjust crystal 5 or catwhisker 12 longitudinally and a disc crank 10 engaging a slot 11 gives rotary adjustment. Contacts 2 are preferably moulded in the casing 1 and extend to the base to form fixing and connecting means.
