Abstract: 577,538. Electric-type linear-dimension gauges. CORNELIUS, J. R. Sept. 22, 1943, No. 15514. [Class 40 (i)] [Also in Group XIX] A linear-dimension gauge comprises means for varying the inductance or capacity, and thus the frequency, of an oscillating circuit in accordance with the dimension gauged, means for heterodyning this variable frequency to produce variable beat-frequency signals, means for reducing the said signals to constant amplitude, and a circuit to convert the frequency variations in said signals with voltage variations which correspond with the dimension gauged. In one form, the work-contacting member 26, Fig. 5, is connected to the movable plate of a condenser 21 mounted on flexible diaphragms 79, 80, the fixed plate 22 being carried on a cam ring 81 adjusted by a screw 82. The plates 21, 22 comprise the variable condenser 3, Fig. 1, arranged in a circuit maintained in oscillation at a basic frequency of, e.g., 4,000 kilocycles/sec. by a valve 7 connected by a condenser 30 to an amplifier 31. Signals at a frequency of 4,500 kilocycles/sec. are injected into the valve 31 from a circuit 37 and amplified heretodyned signals of frequency within the region of 500 are selected by coupled circuits 34, 42 and amplified and filtered by valve circuits 43, 47 and reduced to constant amplitude by a valve 50. The anode circuit 51 of the valve 50 is coupled to two circuits 53, 54 tuned (in the case where the maximum frequency in circuit 2 is 40 kilocycles/sec.) to 480 and 520 kilocycles/sec. respectively, the circuits being so connected to a valve 58 and resistance network 55 that the voltage across points 63, 64 is a measure of the frequency in the circuit 2. This voltage is amplified by a valve 61 and applied to an indicator or recorder. In a modification, the variable condenser has a plurality of fixed and movable plates. A lever or a liquid column may be interposed between the member and the condenser or inductance.

Abstract: 1,004,418. Measuring traffic flow and concentration. DECCA Ltd. Oct. 26, 1962 [April 24, 1962], No. 15626/62. Heading G4Q. Apparatus for measuring traffic flow or traffic concentration, the former being defined as the number of vehicles passing a point in a given time, and the latter as the number of vehicles in a unit length of road, comprises a sensor which produces a pulse each time a vehicle passes over it to actuate a relay, a first capacitor being charged over a normally closed contact of the relay and discharged into a second capacitor, incorporated in a leaky integrator, each time the relay operates. The relay contact 10, Fig. 1, is changed over by each pulse from the sensor (not shown). For measuring traffic flow link 16 is left in circuit and link 11 disconnected so that capacitor 13 is normally charged over resistor 12. On operation of relay 10, capacitor 13 discharges into capacitor 17 of the leaky integrator including the resistance 20. The sum voltage across capacitor 17 is applied to the grid of triode 22 and ready on meter 27. A neon tube 25 prevents the grid voltage from rising above a predetermined value and a rectifier 28 prevents the cathode going negative when the apparatus is first switched on. A capacitor 30 may be connected in shunt with 17 to vary the time constant. (A Miller integrator may alternatively be used. For measuring traffic concentration link 11 is left in circuit and link 16 removed so that capacitor 13 is premanently connected to the D.C. supply and only provides smoothing therefor, while capacitor 17 is charged every time relay 10 is closed, the incremental charges fed to the capacitor 17 depending on the duration of closure of the relay contact. The outputs of a traffic flow and a concentration measuring unit may be applied to a quotient meter to derive the traffic speed. Additional circuitry may be provided (Fig. 2, not shown) to prevent the charge building up beyond a certain limit due to a vehicle stopping on a sensing pad, and an alarm may be operated when this occurs. In order to improve the output linearity at high rates of traffic flow a further contact 50 (Fig. 3) of the relay connects capacitor 13 to the cathode of triode 22 so that the same charge is fed from capacitor 13 into the integrator irrespective of the voltage on the cathode. A similar arrangement for traffic concentration is described with respect to Fig. 4 (not shown). Specification 1,004,414 is referred to.
