Abstract: 1,264,186. Liquid scintillation spectrometers. NUCLEAR-CHICAGO CORP. Sept. 18, 1969 [Sept.20, 1968], No.45967/69. Heading G1A. In a liquid scintillation spectrometer system, sample counting and standardization using an external standard radio-active source take place concurrently, by the use of coincidence and anticoincidence circuitry. The apparatus comprises a liquid scintillator sample vial 10, containing the isotope to be investigated, located between photomultipliers 11, 12, in the usual configuration. If lower accuracy is allowable only one photomultiplier may be used. A further photo-multiplier 20 is mounted adjacent the sample and is provided with a thin scintillation crystal 21 having a radioactive isotope dispersed therein. This is of a type producing at least one non-penetrating radiation and at least one penetrating radiation in substantial coincidence for each decay event. For example, Am 241, producing an α-particle in coincidence with a y-ray emission, is suitable or isotopes decaying by #-y or positron annihilation processes may be used. Each event produces a scintillation in crystal 21 (detected by 20 and due to the non-penetrating radiation) and a standardizing scintillation in the liquid scintillator in vial 10 (due to the penetrating radiation and detected by 11 and 12). The events detected by 11 and 12 thus comprise a mixture of sample and standardizing events. These are separated by circuits 32, 33. The latter produces at its output pulses due only to standardizing events, since it detects coincidence between pulses from detectors 11, 12 (via coincidence circuit 31 to remove noise) and from detector 20 (via pulse height discriminator 30 to remove noise again). Circuit 32 only allows to pass those pulses which are not in coincidence with those from detector 20. Circuits 32, 33 may comprise respectively, a series combination of NOT and AND gates (34), (35) and an AND gate (33), Fig.2 (not shown). Alternatively to circuits 32, 33, and with suitable modifications to the overall system circuitry a combination of a NOT gate (34), a switch (37) and an AND gate (36) provide an output on a single output line which is selectively standardizing or sample pulses, Fig.3 3 (not shown). As a further alternative, Fig.4 (not shown), a combination of a NOT (34) and an AND gate (35) provide on two output lines sample pulses only and both sample and standardizing pulses, respectively. The elimination of the NOT gate in this alternative would give standardizing events on one line and the combination on the other. Pulse height analysis of the pulses is provided by the use of summing circuit 40, analysers 41, 42 and coincidence circuits 50-53, to arrange for counting on scalers 60-63. The counts and the channels ratio calculated by computer 70 may be displayed at 71.

Abstract: 1326016 Measuring temperature acoustically UNITED KINGDOM ATOMIC ENERGY AUTHORITY 15 Oct 1970 [25 Nov 1969] 57729/69 Heading H4D In an arrangement for measuring temperature utilizing an acoustic thermometer of the kind described in Specification 1,146,520 in which resonance of a probe is detected as a driving oscillator is swept over a range of frequencies, means is provided for deriving a control signal from the resonant condition of the probe and for employing the control signal to maintain the frequency of the oscillator at the resonant frequency. Thus, as shown in Fig. 1, the probe comprising a 1 c.m. length of wire 1 joined to a solid cylinder 2 which is joined to a transmission wire 3, all the elements being formed of molybdenum, is vibrated by a magnetostrictive rod 4 polarized by a permanent magnet 5 and driven by a coil 6 supplied via a pulser 16 with the output of an oscillator 11 the frequency of which may be swept over the range 100-150 Kc/s. as a direct function of a D.C. control voltage produced in a circuit 13. In operation, echo signals derived from the probe and which have the form shown at A in the out of resonance condition and the form shown at B in the resonance condition, are supplied via amplifier 10 to a gate 11 pre-adjusted in accordance with the length of the transmission line and the sonic velocity of the material to pass only a small portion of the echo signal within which, at resonance, a null occurs (C or D). The output from gate 11 is then rectified and inverted in circuit 12 (E or F) and the output employed in a monostable circuit 13 incorporating an integrating capacitor to produce either a falling D.C. voltage G or a rising D.C. voltage H and such voltage is then employed to control the frequency of oscillator 14. A voltmeter 17 indicating the voltage across the integrating capacitor is calibrated in terms of temperature and the frequency of oscillator 14 is indicated digitally by means 15. In a modification which prevents "hunting" of the oscillator frequency around the resonantnon-resonant conditions the voltage controlling the oscillator frequency is provided by the charging of a high-value capacitor the charging being interrupted when resonance is detected so that the oscillator frequency is held at the resonance value. This condition is maintained for about two seconds and during this period a temperature calibrated read-out device is connected to indicate the frequency of the oscillator (Figs. 2 to 8, not shown).
