摘要： A system for measuring the speed and length of a moving elongated article, such as a moving wire exiting from an insulating process, includes a roller of precisely measured circumference in frictional contact with the wire, a transducer for generating a precise number of pulses in response to each revolution of the roller and a counting unit for receiving the generated pulses. The circumference of the roller is preset into the counting unit to control a pulse multiplying circuit and a time period during which the pulses are counted. The counted pulses are divided down to render one pulse for each foot of wire moved past the roller and are coupled to a footage counter to indicate the length of wire which may be taken up on a strand take-up apparatus. The transducer pulses may be counted for the variable time period and displayed directly as the foot per minute speed of the wire. Additionally, preset high and low speed tolerance limits may be compared to the measured speed of the wire to activate alarm circuitry for measured speeds falling without the limits. The system may be interfaced with a computer to monitor or control the insulating process.

摘要： A twisted pair of insulated conductors is passed axially through a pair of longitudinally spaced, capacitive electrodes, each having a random distribution of conductive spheroids contained therein to center the wire within the electrodes, bring the electric field closer to the wires and obtain a uniform potential gradient therearound. The electrodes are tubular shaped, having equal diameters but unequal lengths and are held at a predetermined potential difference, for example, 2.5 kilovolts, by connecting them respectively to the opposite sides of a circuit arrangement including a high voltage transformer secondary winding in series with a resistor and a capacitor connected in parallel. During normal operation, the two electrodes, the wire insulation and the wires define a pair of parallel arms each consisting of two series-connected capacitors. As the twisted wire pair is passed through the electrodes, an insulation fault, for example, a bare wire, split insulation, void, short circuit between the wires, or runout of one or both wires, causes a breakdown of one or both capacitors. This abrupt change in capacitance generates a transient pulse in the circuit which may be detected, for example, by a sensing or pickup coil disposed around one of the circuit connecting wires, and may be amplified and utilized to stop the longitudinal advance of the twisted wire pair to permit the fault to be located and repaired.

摘要： In a constant current charging tenchique for measuring capacitance, a constant current is supplied to a capacitance to be measured and a voltage ramp is produced. Two voltage-level detectors sense the ramp. At a low level on the ramp, a first of the detectors triggers a time-interval meter which begins to count pulses from an oscillator. A second of the detectors stops the counting process when the voltage ramp reaches an upper level. The time measured by the meter is proportional to the value of the capacitance and can be used to calculate the actual value.
