Abstract

227,680. Harris, A. W., and Newson, G. April 9, 1924. Crystal detectors comprise an arm a loosely pivoted on ar insulating member i and carrying at one end the crystal e and at the other a pair oi studs b. The crystal and the studs rest on two metallic plates n, n<1>, connected to the terminals of the detector. The plate n<1> is recessed as shown to prevent the studs from sliding over the edge.
