Vibrational wave generator

Claim 1

IN A METHOD FOR VIBRATING AN OIL-BEARING FORMATION WHEREIN INTENSIVE WAVE ENEGY IN THE SONIC FREQUENCY RANGE IS GENERATED AT THE EARTH''S SURFACE AND IS TRANSMITTED TO A SUBSURFACE OIL-BEARING FORMATION, SAID WAVE ENERGY BEING OF SUFFICIENT MAGNITUDE TO VIBRATE A SUBSTANTIAL PORTION OF SAID FORMATION AND CAUSE AN INCREASED FLOWRATE OF INTERSTITIAL FLUID THERETHROUGH, THE IMPROVED METHOD FOR GENERATING AND TRANSMITTING SAID WAVE ENERGY WHICH COMPRISES DISPOSING A TRANSDUCER IN SAID FORMATION, RESILIENTLY COUPLING SAID TRANSDUCER TO THE DRIVEN MEMBER OF A MAGNETIC CLUCH, ROTATING THE DRIVING MEMBER OF SAID MAGNETIC CLUCH BY MEANS OF A POWER SOURCE CAPABLE OF APPLYING A STRONG MOMENTARY TORQUE TO SAID DRIVING MEMBER, AND ALTERNATELY MAGNETIZING AND DEMAGNETIZING THE FLUID OF SAID MAGNETIC CLUCH AT A RATE GREATER THAN ABOUT 10 CYCLES PER SECOND BY MEANS OF A PULSATING ELECTRICAL CURRENT, THE MAGNETIZING POWER SUPPLIED TO SAID CLUCH FLUID BEING SUBSTANTIALLY LESS THAN THE TORQUEPRODUCING POWER SUPPLIED TO SAID DRIVING MEMBER, AND CONTROLLED IN PERIODICITY AND WAVE FORM WHEREBY SAID TRANSDUCER IS CAUSED TO VIBRATE BY THE ALTERNATE COUPLING AND UNCOUPLING OF SAID DRIVING MEMBER AND SAID DRIVEN MEMBER TO APPLY SUCH CONTROLLED VIBRATIONS TO THE FORMATION.
