Claim 1
Independent Claim
168 words
IN A DEVICE FOR UNDERWATER COMMUNICATION, INCLUDING: AN ELECTRICAL POWER SOURCE; AN AMPLIFIER OPERATIVELY CONNECTED TO THE POWER SOURCE; AND A DIAPHRAGM OF MAGNETIC MATERIAL HAVING ONE SURFACE IN WATER CONTACT WHEN IN USE; THE IMPROVEMENT IN A TRANSDUCER COUPLED WITH THE DIAPHRAGM COMPRISING: A FIRST MAGNETIC CORE SPACED OUTWARDLY ADJACENT TO ONE SURFACE OF SAID DIAPHRAGM; A FIRST SIGNAL COIL OPERATIVELY CONNECTED TO SAID AMPLIFIER, SAID SIGNAL COIL BEING WOUND ABOUT SAID MAGNETIC CORE; A FIRST FIELD COIL WOUND ABOUT SAID CORE; A SECOND MAGNETIC CORE IDENTICAL TO SAID FIRST MAGNETIC CORE AND LOCATED IN OPPOSITION THERETO OUTWARDLY ADJACENT THE REMAINING SURFACE OF SAID DIAPHRAGM; A SECOND SIGNAL COIL OPERATIVELY CONNECTED TO SAID AMPLIFIER, SAID SECOND SIGNAL COIL BEING WOUND ABOUT SAID SECOND MAGNETIC CORE; A SECOND FIELD COIL WOUND ABOUT SAID SECOND MAGNETIC CORE; AND SELECTIVELY OPERABLE SWITCH MEANS CONNECTED TO SAID FIRST AND SECOND FIELD COIL AND TO SAID POWER SOURCE TO COMPLETE AN ELECTRICALLY CONDUCTIVE CIRCUIT BETWEEN SAID FIELD COIL AND SAID POWER SOURCE.

Claim 3
Dependent Claim
70 words
A TRANSDUCER FOR UNDERWATER COMMUNICATION COMPRISING: A DIAPHRAGM OF MAGNETIC MATERIAL HAVING ONE SURFACE IN WATER CONTACT WHEN IN USE; AND A PAIR OF OPPOSED MAGNETIC STRUCTURES OF IDENTICAL DESIGN, LOCATED OUTWARDLY ADJACENT THE RESPECTIVE SURFACES OF SAID DIAPHRAGM, EACH MAGNETIC STRUCTURE COMPRISING: A CORE HAVING ONE END TERMINATING ADJACENT THE DIAPHRAGM, BUT SPACED THEREFROM; A SIGNAL COIL WOUND ABOUT SAID CORE; AND A FIELD COIL SUPERIMPOSED ON SAID CORE.
