Abstract

1,094,702. Electric selective signalling. PLESSEY-U.K. Ltd. Aug. 21, 1964 [Aug. 23, 1963], No. 33455/63. Heading G4H. [Also in Division G1] The charge on a capacitor 6 representative of the dose of neutrons used in activation analysis is measured by discharging the capacitor with pulses from a clock-pulse generator 19 and counting the number of pulses used on a scale connected to lead 20. When the charge on capacitor 6 is reduced to zero, the base potential of transistor 12 is zero, and the latter conducts to terminate transmission of pulses to the sealer. The measurement may be started while capacitor 6 is still being charged, and continues until the capacitor is discharged.
