Abstract
287,324. Wixcey, E. A. March 26, 1927. Crystal detectors.-A resistance comprising a helical wire is inserted in the detector circuit between one of the elements of the detector combination and the terminal. As shown, a crystal cup 9 is slidably mounted in an insulating sleeve 8 which is supported on terminal bushes 6, 9 secured to standards 4, 5. The cup 9 is pressed into contact with a disc 18 of copper &c. which in turn engages a block 17 of carbon mounted in a cup 16, by a spring 13 of resistance wire which forms the electrical connection between the crystal and 'the bush 6. The cup 16 is mounted on an adjustable rod 14. In a modification, the cup 9 is carried by a rod which is slidably mounted in the bush 6.
