Abstract

575,805. Piezo - electric crystals. TENENBAUM, B. April 6, 1944, No. 6493. [Class 40 (v)] A piezo-electric crystal unit has its power handling capacity increased by being formed of a number of identical crystal plates mounted in series. A set of crystal plates a similarly orientated and having the same frequency are placed between pairs of electrodes f separated by insulating frames e, the whole assembly being clamped between insulating plates b and supported by rods d on a base c. The crystal plate a and electrodes f are connected in series to form a high impedance unit of greater impedance and power handling capacity than a single element.
