Abstract

798,143. Printed circuits. GENERAL ELECTRIC CO., Ltd. March 5, 1957 [March 5, 1956], No. 6852/56. Drawings to Specification. Class 37. Instability in a printed circuit, high-gain amplifier is prevented by connecting a lowimpedance conductor in parallel with the printed earth line. As described, the earth line, which forms the margin of a copper-clad circuit board, is in contact with a flange on a tin-plate chassis.
