[Also in Division H3] A voltage to frequency transducer in which the transducer output signal appears either at alternative output points or has a polarity depending on the polarity of the input signal includes a feed back loop producing a signal compensating for drift in the base line of the input signal.. In the embodiment described the transducer 11 includes a Miller integrator circuit 48 (Fig. 3) having a conventional charging capacitor 50 and resistance 98. As the output signal at terminal 99 attains a pre-determined level one of two transistors 51, 52 is driven into a state of conduction by one of two trigger circuits 58, 57 respectively so that capacitor 50 discharges through the conducting transistor. The trigger circuits 51, 52 control waveshaping stages 128, 138 so that the frequency of output pulses at one of the terminals 26, 27 corresponds to the magnitude of the input signal and the polarity of the input signal is determined by the terminal at which the pulses appear. The pulses are then applied to a ring counter 28 (Fig. 2) which gives an output signal sequentially on leads 1, 2, 3, 4 to OR gates 29, 30, 31, 32 to control the windings 35, 38 of the rotor 39 of a stepping motor. As the rotor rotates a mechanically connected slider is moved so that a correction voltage is applied to the transducer.

Title: Improved electronic frequency meter
IPC: G01R23/09
Filed: 1953-10-29
Abstract: 746,195. Frequency measurement; pulse generating circuits. NATIONAAL LUCHTVAARTLABORATORIUM. Oct. 29, 1953 [Oct. 30, 1952], No. 29976/53. Classes 40 (5) and 40 (6). An electronic frequency meter comprises a pulse generator (valves 5, 8) producing one pulse per cycle of A.C. input, and a monostable valve pair 16, 17 triggered by the pulses and producing for each pulse a rectangular anode current pulse of constant amplitude and duration, whose repetition frequency is measured by a D.C. meter M in the anode circuit. As shown, the pulse generator 5, 8 is a known cathode-coupled bi-stable valve pair 5, 8 whose pulse output is differentiated by a capacitor 13 and resistor 14 and, due to the rectifier 15, only the negative-going pulse trailing edges are applied to the suppressor grid of valve 16 to render it temporarily non-conducting. The pulse output of valve 16 is applied to the grid of pentode valve 17 through a normally conducting diode 20 in series with the grid and a resistor 23 connected to a tapping T of a voltage divider 29, 30, 28 connected across a voltage stabilizing tube 24, i.e. the grid voltage increases to an upper value limited by the voltage of the tapping T. Further, the grid is prevented from being driven below earth potential by a clamping diode 26 by-passing to earth the diode 20. Equal amplitude pulses are therefore produced in the anode circuit of duration determined by the capacitor 21 and series charging resistors. Effects of H.T. variation are counteracted by including a resistor 28 in the cathode circuit of valve 17, since H.T. variation produces equal changes at the anode and cathode of the pentode 17 (if the anode current is maintained constant as is the function of the circuit) and at the anode and cathode of the stabilizer tube 24, but only a portion, i.e. R 29 /R 29 +R 30 , of the variation at the anode of tube 24 is applied to the tapping T and grid of the pentode 17, i.e. increase in current is counteracted. Temperature variation of anode resistor 31 or of the upper part of resistor 22 varies the pulse duration and amplitude respectively, or variation of the lower part of resistor 22 varies both. To this end the resistor may be positioned near the effect, e.g. fluid flow, being metered, and have a positive temperature coefficient to compensate for changes in fluid density due to temperature. The frequency meter may also measure rotational speed and totalise revolutions as in Specifications 746,190 and 746,191, [both in Group XXXVIII].
