Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A MODULO-N COUNTER FOR FLUID COUNTING PULSES, SAID COUNTER COMPRISING A SERIES OF FLUID AMPLIFIERS EACH HAVING AN INTERACTION CHAMBER, AT LEAST ONE OUTPUT CHANNEL, AND AT LEAST ONE CONTROL NOZZLE FOR EMITTING CONTROL FLUID FOR DEFLECTING A POWER JET INJECTED INTO SAID CHAMBER INTO SAID OUTPUT CHANNEL; MEANS INCLUDING A PLURALITY OF SIGNAL DELAY MEANS FOR DELAYING FLUID SIGNALS APPLIED THERETO FOR A PREDETERMINED INTERVAL OF TIME, EACH SAID MEANS BEING RESPONSIVE TO POWER JET FLOW IN SAID ONE OUTPUT CHANNEL OF ONE AMPLIFIER OF SAID SERIES FOR INJECTING A POWER JET INTO THE INTERACTION CHAMBER OF THE NEXT AMPLIFIER IN SAID SERIES; MEANS FOR PERIODICALLY PRODUCING FLUID PULSES EACH OCCURRING FOR AN INTERVAL OF TIME LESS THAN SAID PREDETERMINED INTERVAL, SAID MEANS PRODUCING SAID FLUID PULSES AT INTERVALS OF TIME GREATER THAN SAID PREDETERMINED INTERVAL; AND MEANS FOR SIMULTANEOUSLY APPLYING EACH OF SAID FLUID PULSES TO SAID CONTROL NOZZLES OF EACH OF SAID AMPLIFIERS.
Claim 2
Dependent Claim

A MODULO-N COUNTER FOR FLUID COUNTING PULSES, SAID COUNTER COMPRISING A SERIES OF FLUID AMPLIFIERS EACH HAVING AN INTERACTION CHAMBER, AT LEAST ONE OUTPUT CHANNEL, AND AT LEAST ONE CONTROL NOZZLE FOR EMITTING CONTROL FLUID FOR DEFLECTING A POWER JET INJECTED INTO SAID CHAMBER INTO SAID OUTPUT CHANNEL; MEANS INCLUDING A PLURALITY OF SIGNAL DELAY MEANS FOR DELAYING FLUID SIGNALS APPLIED THERETO FOR A PREDETERMINED INTERVAL OF TIME, EACH SAID MEANS BEING RESPONSIVE TO POWER JET FLOW IN SAID ONE OUTPUT CHANNEL OF ONE AMPLIFIER OF SAID SERIES FOR INJECTING A POWER JET INTO THE INTERACTION CHAMBER OF THE NEXT AMPLIFIER IN SAID SERIES; MEANS FOR PERIODICALLY PRODUCING FLUID PULSES EACH OCCURRING FOR AN INTERVAL OF TIME LESS THAN SAID PREDETERMINED INTERVAL, SAID MEANS PRODUCING SAID FLUID PULSES AT INTERVALS OF TIME GREATER THAN SAID PREDETERMINED INTERVAL; AND MEANS FOR SIMULTANEOUSLY APPLYING EACH OF SAID FLUID PULSES TO SAID CONTROL NOZZLES OF EACH OF SAID AMPLIFIERS.
Claim 3
Dependent Claim
138 words
A FLUID AMPLIFIER HAVING AN INTERNAL CHAMBER CONFIGURATION WHEREBY AN INJECTED POWER STREAM OF PREDETERMINED VELOCITY CREATES FORCES WITHIN SAID CHAMBER TO HOLD SAID POWER STREAM IN A FIRST OR A SECOND STABLE PATH OF FLOW, POWER NOZZLE MEANS FOR NORMALLY INJECTING A POWER STREAM INTO SAID CHAMBER AT LESS THAN SAID PREDETERMINED VELOCITY, SAID POWER NOZZLE MEANS INCLUDING A VELOCITY CONTROL NOZZLE LOCATED IN THE REGION WHERE THE POWER STREAM IS INJECTED INTO SAID CHAMBER, SAID VELOCITY CONTROL NOZZLE BEING DIRECTED AT SUBSTANTIALLY RIGHT ANGLES TO THE POWER STREAM AND BEING RESPONSIVE TO A FLUID CONTROL SIGNAL APPLIED THERETO FOR RESTRICTING THE EFFECTIVE ORIFICE SIZE OF THE POWER NOZZLE MEANS AND THEREBY FOR ACCELERATING SAID POWER STREAM TO A VELOCITY GREATER THAN SAID PREDETERMINED VELOCITY WHEREBY SAID POWER STREAM ASSUMES ONE OF SAID STABLE PATHS OF FLOW.
