Filed: 1970-09-28
Abstract: 1328520 Liquid scintillation spectrometry INTERTECHNIQUE S A 28 Sept 1970 [1 Oct 1969] 46094/70 Heading G1A Conventional liquid scintillation spectrometer apparatus is controlled to operate automatically on a series of samples by a digital computer. For each sample, the level of quenching is measured by the external standards or channels ratio method, the computer being programmed in accordance with the method chosen, to calculate the necessary amplitude limits of the counting channels, in dependence on the measured quenching lead, to satisfy a chosen criterion, there being a circuit link from the computer to the pulse height discriminators of the counting channels, by which these limits are automatically set before the sample count is carried out. The criteria to be satisfied may be: maximization of the figure of merit (counting efficiency); minimization of spill over when the sample contains two (or more) isotopes each with their respective counting channels; maintenance of constant background level. The computer is provided with stored information in the form of curves of amplitude limit values (for the counting channels) as a function of the degree of quenching. This enables during the measurement of quenching, the performance of calculations of the limit values required for each particular sample. The stored information is obtained by a series of measurements on samples having known activities and known different degrees of quenching. The apparatus is provided with manually operated dial switches to alter the pulse height discriminator levels to aid this calibration. The stored curves may be in the form of coefficients of polynomial equations or values of points along the curve (from which the required values for any particular sample are calculated by interpolation).

Title: Improvements in or relating to circuit arrangements producing output pulses at a desired frequency
Inventor: FENTON ROGER WAKEFIELD
IPC: H03K25/00
Filed: 1962-12-18
Abstract: 1,007,391. Semi-conductor frequency dividers and oscillators. MARCONI CO. Ltd. Oct. 31, 1963 [Dec. 18, 1962], No. 47651/62. Heading H3T. A frequency divider or oscillator comprises a first condenser connected to a charging source which may be a source of input pulses, a second condenser connected in sequence with the first and a 4-layer diode connected across each condenser. The first few input pulses to the circuit of Fig. 1 will cause C1 to charge step-wise until the 4-layer diode D1 breaks down. Current will then flow into C2 until the voltages across C1 and C2 are equal whereupon D1 will become non-conducting. The next two input pulses will increase the voltage across C1 such that D1 again breaks down and the voltages on C1 and C2 are equalized. This continues until a 4-layer diode D2 breaks down whereupon both C1 and C2 discharge and the cycle recommences. An output pulse may be taken from R or from a differentiator connected across C2 (Fig. 2, not shown). The input pulses are equalized by a diode pump-type circuit in which a capacitor K is discharged via a diode D into C1 at each pulse and in which between each pulse a transistor emitter follower T becomes conductive to raise the potential of the right-hand plate of K to that of C1. Additional diode-capacitor stages may be provided between D1 and D2 to increase the division ration (Figs. 3 and 7, not shown) and normal diodes can be added in series with the 4-layer diodes to prevent reverse conduction. Current limiting resistors may be added in series with the capacitors (Fig. 8, not shown). An oscillator-divider (Fig. 4) comprises a capacitor C1 which charges via a constant current transistor circuit T1. The charge increases until a 4-layer diode D1 breaks down whereupon C1 discharges into C2 until the current is insufficient to maintain the diode conducting whereupon charging of C1 recommences. The cycle is repeated until a 4-layer diode D2 breaks down and discharges both C1 and C2 to allow the charging of C1 to recommence. Output pulses may be extracted and the additional stages may be added, as in the previous circuits.
