Title: Improvements in or relating to the electrical measurement of short time intervals
IPC: G04F10/00
Filed: 1943-11-26
Abstract: 569,296. Valve circuits. DUNDAS, Ltd., R. K., and HITCHCOX, G. I. Nov. 26, 1943, No. 19785. [Class 40 (v)] [Also in Group XXXVI] Apparatus for measuring short time intervals by charging a condenser through a valve which is rendered conductive during the time interval and measuring the potential to which the condenser is charged is so arranged that no potential is applied across the timing circuit except during the interval to be measured. In the apparatus shown in Fig. 2, a trigger valve V1 is normally negatively biassed to pass little or no current. A reservoir condenser Cr is charged through a resistance R and a diode V3 nearly or fully to the voltage of supply. During the interval to be measured between two phenomena, the valve V1 is made conductive by the closure of contacts X and the condenser Cr discharges through the valve V1 and a constant current valve V2, charging the timing condenser Ct. The voltage developed across this condenser indicates the duration of current flow. The reservoir condenser Cr is made large enough to supply adequate anode current for the constant current valve V2 for the longest time interval it is proposed to measure'and without causing too large a voltage drop across the condenser Cr. The second phenomenon makes the valve V1 non-conductive by opening the contacts X and the condenser Cr recharges through the resistance R and diode V3. None of this recharging current passes through the valve V2 because it is short-circuited by the diode V3. Fig. 3 shows a modification in which a valve V4 combines the functions of trigger valve and constant current valve and takes the place of the valve V1, Fig. 2. The valve V2 is replaced by a diode V6.
