Abstract

477,344. Direct connection between conductors. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., KEALL, O. E., and SMITH, E. O. June 25,1936, No. 17689. [Class 38 (i)] [Also in Group XL] A piezo-electric crystal 5 is supported between metal-wool pads 10, 11, which make electrical contact with opposite faces of the crystal and preferably form leads from the electrodes deposited on the crystal.
