Abstract: The fluidic oscillator flow meter splits (5) the flow into two channels (3,4) from which respective feedback channels (6,7) lead back to adjacent the inlet (2). Magnets (8,9,12.13) maintain magnetic fields across the two channels and the feedback channels. - The frequency of oscillation of the flow between the two channels is determined by measuring the potential differnce across each channel in a direction perpendicular to the field and the direction of flow. Complentary sets of measurement electrodes (10,11, and 14,15) may be connected in push-pull.

Abstract: In accordance with one aspect of the invention, there is provided a time difference correction circuit for correcting  time  differences  between   luminance   and chrominance signals derived from a detected signal from a videotape.    The  circuit  includes  a  luminance  signal detecting circuit, a chrominance signal detecting circuit, a mixing circuit, a vertical synchronization circuit and a timing control circuit.   The luminance signal detection circuit extracts a  luminance signal  from the detected signal.  The chrominance signal detection circuit extracts a chrominance signal from the detected signal and includes a controllable delay line for delaying the chrominance signal by a controllable amount of time to produce a time difference  corrected  chrominance  signal.    The  mixing circuit mixes the luminance signal and the time difference corrected chrominance signal to produce a composite video output  signal.    The  vertical  synchronization  circuit detects a vertical synchronization signal in the luminance signal and delays the vertical synchronization signal to produce a delayed vertical synchronization signal.   The timing control circuit determines a time difference between the luminance and chrominance signals for each field in a horizontal interval, in response to the delayed vertical synchronization signal and outputs a control signal to the controllable delay line, the control signal corresponding to the time difference between the luminance signal and the chrominance signal.  The delay produced by the time delay is varied to correct the time difference.
