Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
70 words
APPARATUS COMPRISING A TRANSDUCER, A COUPLER WHOSE TEMPERATURE INCREASES WHEN TRANSMITTING ENERGY TO PERFORM USEFUL WORK, SAID COUPLER BEING FIXEDLY SECURED TO SAID TRANSDUCER, A GENERATING MEANS COUPLED TO SAID TRANSDUCER, MEANS FOR SENSING TEMPERATURE CHANGES IN SAID COUPLER, AND MEANS COUPLED TO SAID SENSING MEANS FOR MAINTAINING THE FREQUENCY OF SAID GENERATING MEANS SUBSTANTIALLY AT THE OPERATING FREQUENCY OF SAID TRANSDUCER IN RESPONSE TO TEMPERATURE CHANGES IN SAID COUPLER.
Claim 2
Dependent Claim
114 words
IN A METHOD OF OPERATING A GENERATING MEANS COUPLED TO A TRANSDUCER SO THAT THE TRANSDUCER IS EXCITED BY SAID MEANS AND SAID TRANSDUCER BEING CONNECTED TO A COUPLER MEMBER ADAPTED TO PERFORM USEFUL WORK, THE STEPS OF PERFOMING USEFUL WORK BY DELIVERING VIBRATOR ENERGY FROM SAID COUPLER MEMBER FOR A SUFFICIENT PERIOD OF TIME SO THAT THE TEMPERATURE OF SAID COUPLER MEMBER CHANGES, SENSING TEMPERATURE CHANGES IN SAID COUPLER MEMBER, AND CONTROLLING THE FREQUENCY OF SAID GENERATING MEANS IN RESPONSE TO THE SENSED TEMPERATURE CHANGES SO AS TO MAINTAIN THE FREQUENCY OF SAID GENERATING MEANS WITHIN A PREDETERMINED RANGE CLOSELY CENTERED AROUND THE OPERATING FREQUENCY OF SAID COUPLER MEMBER AT ITS CHANGED TEMPERATURE.
