Abstract

1,079,913. Gasfilled tube relay operating circuits. PERVY GOSUDARSTVENNY PODSHIPNIKOVY ZAVOD. Aug. 21, 1964, No. 34240/64. Heading H3P. [Also in Divisions G1, H1] In a flaw detector (see Division G1), when the voltage from a measuring circuit (29) exceeds a value determined by a D.C. reference voltage produced by a circuit (31) diode 73 conducts whereby a signal is passed from a generator 32, through an amplifier 33, to trigger a thyratron 78 thereby actuating a relay 79 which closes contacts 81 extinguishing the thyratron. The relay may be held in its actuated position or released by opening a switch 43.
