Signal summing point device for hybrid fluid and electronic controls

Claim 1

APPARATUS FOR MODULATING A FLUID CONTROL SYSTEM POWER STREAM WITH FIRST AND SECOND CONTROL SIGNALS CONSISTING OF A VARIABLE ELECTRICAL SIGNAL AND A VARIABLE FLOW LIQUID STREAM, RESPECTIVELY, SAID APPARATUS COMPRISING; (A) A BODY MEMBER FORMING A LONGITUDINALLY EXTENDING POWER STREAM INPUT DEFLECTION PASSAGE TO THE TYPE HAVING A POWER STREAM INPUT OPENING AT ONE END FOR DIRECTING A POWER STREAM INTO SAID PASSAGE IN A DIRECTION ALONG ITS LONGITUDINAL AXIS, THE WALLS OF SAID PASSAGE AT THE OTHER END OF THE PASSAGE FORMING FIRST AND SECOND OUTPUT STREAM OPENINGS DISPOSED TO ONE AND THE OTHER SIDES OF A FIRST LONGITUDINAL REFERENCE PLANE THROUGH THE LONGITUDINAL AXIS OF THE PASSAGE, (B) SAID DEFLECTION PASSAGE HAVING A PAIR OF CONTROL STREAM INLET OPENING FOR APPLYING SAID VARIABLE FLOW LIQUID STREAM TO THE POWER STREAM TO SELECTIVELY DEFLECT SAME TO ONE OR THE OTHER OUTPUT OPENING, SAID OPENINGS BEING DISPOSED IN CONFRONTING ALIGNMENT TO ONE ANOTHER AND IN PERPENDICULAR ALIGNMENT TO SAID REFERENCE PLANE, THE IMPROVEMENTS, IN COMBINATION, (C) SAID POWER AND CONTROL STREAMS BEING OF A CONDUCTIVE LIQUID MEDUIM, (D) MEANS FOR GENERATING A MAGNETIC FIELD HAVING MAGNETIC FORCE LINES EXTENDING THROUGH SAID DEFLECTION CHAMBER IN A DIRECTION ESSENTIALLY PARALLEL TO THE LONGITUDINAL AXIS OF THE PASSAGE, (E) SAID DEFLECTION PASSAGE BEING FORMED BY A PAIR OF OPPOSED WALLS MADE OF AN ELECTRICALLY CONDUCTIVE MATERIAL AND DISPOSED TO ONE AND THE OTHER SIDE OF A SECOND LONGITUDINAL REFERENCE PLANE PERPENDICULAR TO SAID FIRST REFERENCE PLANE, SAID OPPOSED WALLS BEING ADAPTED TO RECEIVE THE VARIABLE ELECTRICAL SIGNAL THEREACROSS, WHEREBY THE PROPORTION OF SAID POWER STREAM FLOWING TO ONE END AND THE OTHER OF SAID OUTPUTS OPENINGS IS VARIED IN ACCORDANCE WITH A COMBINATION OF THE FORCES EXERTED UPON THE POWER STREAM BY THE CONTROL STREAM AND THE HYDROMAGNETIC FORCE EXERTED BY THE MAGNETIC FIELD AND THE SIGNAL ACROSS THE OPPOSED WALLS.
