Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
158 words
AN ULTRASONIC REFLECTION PULSE TESTING SYSTEM, COMPRISING A RATE GENERATOR HAVING AN OPERATING FREQUENCY DETERMINING A DESIRED REPETTION RATE FOR INTERROGATING PULSES, A COMPRESSIONAL WAVE OUTPUT TRANSDUCER FOR COUPLING ULTRASONIC PULSES INTO A WORKPIECE, A TANK CIRCUIT CONNECTED TO SAID TRANSDUCER TO DISCHARGE PULSE TRAINS OF ENERGY THERETO, A PLURALITY OF ENERGY STORAGE AND DISCHARGE DEVICES CONNECTED TO SAID TANK CIRCUIT, AN ADJUSTABLE RESISTOR IN SERIES WITH EACH OF SAID DEVICES FOR EQUALIZING THE CHARGING TIME CONSTANTS THEREOF, A CHARGING SOURCE CONNECTED TO ALL OF SAID DEVICES THROUGH THEIR RESPECTIVE SERIES RESISTORS, AND MEANS CONNECTED BY SAID RATE GENERATOR FOR CAUSING SAID DEVICES TO DISCHARGE SEQUENTIALLY INTO SAID TANK CIRCUIT AT THE DESIRED REPETITION RATE; THE DISCHARGE TIME CONSTANT OF EACH OF SAID DEVICES INTO SAID TANK CIRCUIT BEING SUBSTANTIALLY SMALLER THAN THE INTERVAL BETWEEN SUCCESSIVE CYCLES OF SAID RATE GENERATOR, WHEREBY THE TRANSDUCER IS ENERGIZED BY SUCCESSIVE INDEPENDENTLY OC CURRING EQUAL-AMPLITUDE DISCRETE PULSES FROM THE RESPECTIVE DEVICES.
