High frequency proportional fluid amplifier

Claim 1

A PURE FLUID AMPLIFIER HAVING IMPROVED HIGH FREQUENCY RESPONSE CHARACTERISTICS COMPRISING: MEANS FOR RECEIVING A STREAM OF FLUID; A FLUID INTERACTION REGION; MEANS FOR ISSUING A STREAM OF FLUID THROUGH SAID INTERACTION REGION TOWARDS SAID MEANS FOR RECEIVING; CONTROL STREAM MEANS FOR CONTROLLABLY DEFLECTING SAID STREAM OF FLUID; MEANS FOR DEVELOPING A FORCE FIELD IN WHICH THE POSITIONAL STABILITY OF SAID STREAM VARIES AS A FUNCTION OF THE POSITION OF SAID STREAM IN SAID INTERACTION REGION; MEANS FOR OSCILLATING SAID STREAM AT SMALL AMPLITUDES OF OSCILLATION ABOUT A MEAN POSITION SUCH THAT IN THE ABSENCE OF SAID CONTROL STREAM MEANS SAID MEAN POSITION COINCIDES WITH A POSITION OF MINIMUM STABILITY AND SUCH THAT SAID AMPLITUDES OF OSCIALLATION ARE SUFFICIENTLY SMALL RELATIVE TO THE TRANSVERSE DIMENSION OF SAID INTERACTION REGION THAT IN THE ABSENCE OF SAID CONTROL STREAM MEANS SAID STREAM REMAINS SUBSTANTIALLY PROXIMATE SAID POSITION OF MINIMUM STABILITY; SAID CONTROL STREAM MEANS DEFLECTING THE OSCILLATING STREAM SO THAT MEANS POSITION IS SHIFTED RELATIVE TO SAID MEANS FOR RECEIVING.
