Claim 1
Independent Claim
207 words
A VORTEX DEVICE FOR PERFORMING AN INTEGRATION FUNCTION, COMPRISING A VORTEX CHAMBER HAVING A CENTRAL AXIS, MEANS POSITIONED GENERALLY ADJACENT THE PERIPHERY OF SAID CHAMBER AND ADAPTED TO ISSUE A SHEET OF FLUID INTO SAID CHAMBER WITH SUBSTANTIALLY NO TANGENTIAL VELOCITY RELATIVE TO SAID CHAMBER, CONTROL MEANS ASSOCIATED WITH SAID CHAMBER FOR IMPARTING A TANGENTIAL VELOCITY TO SAID SHEET OF FLUID IN ACCORDANCE WITH AN INPUT SIGNAL, AN OUTLET APERTURE FORMED IN SAID CHAMBER ALONG SAID CENTRAL AXIS FOR EGRESS OF SAID FLUID WITH FLUID CHARACTERISTICS INCLUDING PRESENCE OF A CORE OF FORCED VORTICAL FLOW AND HIGH VISCOUS COUPLING GENERALLY DEFINED BY THE AREA OF SAID APERTURE, SAID CORE OF FORCED VORTICAL FLOW HAVING BOTH A ROTATIONAL COMPONENT OF FLOW AND AXIAL COMPONENTS RELATIVE TO SAID CENTRAL AXIS IN THE PRESENCE OF SAID INPUT SIGNAL, FLUID DRIVEN ROTOR MEANS RESPONSIVE ONLY TO SAID ROTATIONAL COMPONENT OF FLOW OF SAID CORE OF FORCED VORTICAL FLOW, THE OUTER PERIPHERY OF SAID ROTOR MEANS BEING WHOLLY WITHIN SAID CORE OF FORCED VORTICAL FLOW AND HIGH VISCOUS COUPLING AND BEING LOCATED PRIMARILY IN SAID CHAMBER WHEREBY SAID ROTOR MEANS IS SUBSTANTIALLY RIGIDLY COUPLED TO SAID ROTATIONAL COMPONENT OF FLUID FLOW AND DETECTING MEANS FOR SENSING THE ROTATION OF SAID ROTOR MEANS.

Claim 3
Dependent Claim
134 words
A VORTEX AMPLIFIER, COMPRISING A VORTEX CHAMBER HAVING AN AXIS, AN OUTLET APERTURE FOR SAID VORTEX CHAMBER LOCATED ON SAID AXIS, MEANS INDUCING VORTICAL FLOW OF FLUID IN SAID CHAMBER THEREBY FORMING A CORE OF FORCED FLOW OF SOLID BODY ROTATION OF SAID FLUID INTERNALLY OF SAID VORTEX CHAMBER, WHEREIN ANGULAR VELOCITY OF SAID CORE IS CONSTANT WITH RESPECT TO RADIUS OF SAID CORE AND TANGENTIAL VELOCITY OF FLUID IN SAID CORE IS A DIRECT FUNCTION OF RADIUS OF SAID CORE, SAID CHAMBER BEING DIMENSIONED SUCH THAT A CORE OF RELATIVELY UNIFORM DIAMETER IS FORMED AND MEANS FOR PRODUCING AN OUTPUT IN RESPONSE SOLELY TO THE ANGULAR VELOCITY OF SAID CORE SAID LAST-MENTIONED MEANS INCLUDING ROTATION SENSING MEANS HAVING AN AXIAL LOCATION PRIMARILY IN SAID CHAMBER AND A RADIAL LOCATION WHOLLY WITHIN THE CORE.
