    Abstract: In the several preferred embodiments of the present invention disclosed herein, a pneumatic controller is provided with a depending flexible vane which is cooperatively arranged and positioned to be moved in relation to a gas-bleed orifice for selectively regulating the pressure of a gaseous control media being supplied to a pressure-responsive control device. To control the movements of the vane, a variable force is applied to the vane to selectively deflect it in response to variations of a measured condition. Proportional feedback is provided in a unique fashion by supplying the regulated gas to one or more nozzles which are arranged to jet gas against the vane for reestablishing the equilibrium of the vane in accordance with the regulated gas pressure.

    Abstract: Frequency-comparative circuit of two series of pulses comprising a two-output bistable rocker having two inputs respectively receiving said two series of pulses, a flip-flop connected to the outputs of said bistable rocker and having an auxiliary input connected to the output of a two-input delay circuit whose two inputs are themselves connected respectively to the two inputs of said bistable rocker and a two-input NAND circuit of which one input is connected to one of the outputs of said flip-flop and the other input to one of the inputs of said bistable rocker through a reversing circuit whereby one pulse of one of said two series of pulses prevents the passage of the next pulse from the other series thus causing at the output of said NAND circuit pulses corresponding in number to the difference between the number of pulses of said two pulse series.

    Abstract: A method for detection of faults in a polyphase alternating current transmission line system includes the steps of measuring the voltage, current and derivative of the latter for each phase, formulating the equations for the relationship between the measured values of different phases in accordance with Ohm''s law, transforming these equations into forms having straight line characteristics by application of numerical coefficients, and repeating the foregoing steps at regular intervals to obtain successive straight lines which intersect in a single point and the coordinates of which characterize the operation of the system thus to show line operation in either a normal manner or the existence of a phase-to-phase or phase-to-earth fault. The related apparatus for carrying out the method includes various instruments for measuring the voltage, current and derivative of the current at regular intervals, instruments for recording the data and a computer for processing the data thus obtained.
