Filed: 1973-08-31
Abstract: 1435774 Measuring voltage drops STICHTING REACTOR CENTRUM NEDERLAND 31 Aug 1973 [5 Sept 1972] 41170/73 Heading H3H A circuit for measuring the magnitude of a voltage drop of an alternating voltage comprises a plurality of threshold circuits and means for storing the states of the threshold circuits when the voltage drops below a predetermined level. The A.C. voltage is applied at 102 to bridge rectifier 3 and the full wave rectified voltage is smoothed and applied to threshold circuits 4-10 and 20, which comprise comparators with reference voltages set by potential dividers 11 set to 90, 80, 70, 60, 50, 40, 30 and 20% respectively of the nominal voltage. The outputs of comparators 4-10 are applied to circuit 15 which has an output a BCD representation of the comparator output and hence the applied voltage. The BCD values are applied to shift registers 19, 20, 21. Zero crossing of the input signal are detected by circuit 23 which triggers monostable 24 and which, after a given period triggers monostable 25 producing a lmSc. clock pulse at the pripert signal peaks. When the A.C. input is less than 90% of its nominal value, AND gate 31 is enabled and the clock pulses pass via AND gate 31, AND gate 30 and OR gate 29 to the shift input of register 19-21, thus storing the value of input voltage at successive clock intervals. If the input drops below 20% of nominal input, AND gate 26 is enabled and a clock pulse sets bi-stable 27 and shuts gate 30. Thus gates 31 and 26 only permit shift pulses to reach the register when the input is between 20 and 90% of its nominal value. When threshold circuit 4 responds to the input rising to over 90% of nominal, bi-stable 28 is set and an extra shift pulse steps the register, so that a zero is displayed. The register contents may be indicated by lamps and a separate shift register may count the number of times that the input voltage drops below its nominal value.

Abstract: 1333018 Radar GENERAL MOTORS CORP 7 Sept 1972 [12 Oct 1971] 41492/72 Heading H4D In a continuous wave Doppler radar system the ratio of the Doppler frequency shift to the time derivative of the logarithm of the reflected wave amplitude is obtained to give the distance to the reflecting object. It can be shown that the distance x to the reflecting object is given by x = - 2 dx/dt / d (ln y) / dt, where y is the reflected wave amplitude. Gunn diode 12 produces a continuous wave which is transmitted by antenna 18 which also receives the reflection. The resulting Doppler signal is fed to log amp 20. The frequency of the Doppler signal is given by device 22 and is proportional to dx/dt. Rectifier 24 and filter 26 give the logarithm of the amplitude which is differentiated by device 28. Divider 30 gives the expression above and hence distance x. Further circuitry 32, 34 is used to derive the logarithm of the crosssectional area # of the reflecting object. The use of log amps allows a large range of distances and areas to be measured.
