Title: Improvements relating to radiation detectors
Inventor: COPPEN JOHN DAVID

Abstract: 1,110,544. Radiation responsive circuits. GRAVINER (COLINBROOK) Ltd. Aug.18, 1966 [May 27, 1965], No.22511/65. Heading G1A. A radiation responsive circuit comprises a pulse generator which produces pulses of predetermined amplitude in response to the output of a radiation detector, first capacitor means substantially completely charged by said pulses, second capacitor means having a larger capacity charged by transfer of the charge on the first capacitor means at the end of each pulse and means indicating when the charge on said second capacitor means exceeds a predetermined value. A number of detector heads A1-A6 is provided, each comprising a photo-cell PC1 of the type which is filled with a gas which ionizes when subjected to radiation to which is applied A. C. from the mains transformer TR. When a photocell conducts, the negative phase of the oscillations passing therethrough overcomes a 1 volt bias on the corresponding diode D1 to transmit a pulse to a monostable circuit VT1; VT2; VT3. When the monostable circuit is in its unstable state, capacitor C5 charges up, and when the monostable circuit reverts to its stable state, this charge is transferred to the larger capacitor C6. If enough pulses arrive at C6 at a sufficient rate, the voltage thereacross rises to a value sufficient to pull in relay RL1 which remains energized so long as pulses arrive at C6 at a rate sufficient to sustain the holding current for RL1. Closure of the contacts RL1/1 lights warning lamps R and RA, the latter at a remote station U. The current through lamp RA energizes relay RL2 for an alarm bell. The remote station has connections B-F for further banks of detector heads.
