Dry high-pressure potentiometric transducer

Claim 1

A HIGH PRESSURE POTENTIOMETRIC TRANSDUCER FOR TRANSLATING DIRECTLY INTO ELECTRICAL SIGNAL FORM THE PRESSURE EXHIBITED BY A FLUID UNDER HIGH PRESSRUE ADMITTED THERETO, SAID TRANSDUCER COMPRISING: FIRST MEANS, INCLUDING HOUSING AND SUPPORT MEANS AND PROVIDING A CHAMBER AND AN OPENING INTO THE CHAMBER FOR ADMISSION THEREINTO OF FLUID UNDER PRESSURE, SAID FIRST MEANS INCLUDING A THICK ELASTIC DIAPHRAGM OF HIGH RESISTANCE TO DEFROMATION AND OF HIGH NATURAL FREQUENCY OF OSCILLATION SAID DIAPHRAGM FORMING AT LEAST A PORTION OF THE INTERIOR WALL BOUNDING SAID CHAMBER AND HAVING A CENTER PORTION WHICH TRAVELS INCIDENT TO CHANGE OF DEFORMASTION WHICH DIAPHRAGM INCIDENT TO CHANGE OF EXHIBITED PRESSURE; SECOND MEANS, INCLUDING POTENTIOMETER MEANS HAVING FIRST AND SECOND ELECTRICAL COMPONENTS THE FIRST OF WHICH IS A RESISTANCE ELEMENT AND THE SECOND OF WHICH IS A WIPER CONTACT, ONE OF SAID COMPONENTS BEING SUPPORTED BY SAID FIRST MEANS AND THE OTHER OF SAID COMPONENTS BEING MOVABLE; THIRD MEANS, INCLUDING FIRST INTEGRAL LEVER MEANS COMPRISING A FIRST LEVER DEVICE COMPRISING A RIGID PORTION CONNECTED TO SAID FIRST MEANS FOR SUPPORT THEREBY AND COMPRISING FIRST SUBSTANTIALLY FRICTIONLESS FLEXIBLE MEANS FORMING PART OF SAID LEVER DEVICE AND PERMITTING LIMITED MOVEMENT OF A MOVABLE PORTION OF THE LEVER DEVICE ABOUT A ZONE OF FLEXURE AND SAID THIRD MEANS INCLUDING FIRST TRANSMITTER MEANS INTEGRALLY INTERCONNECTING SAID DIAPHRAGM AND SAID FIRST LEVER DEVICE FOR LOSSLESS TRANSMISSION OF MOTION OF SAID CENTER PORTION OF SAID DIAPHRAGM TO SAID FIRST LEVER DEVICE TO MOVE THE SAID PORTION THEREOF INCIDENT TO CHANGE OF DEFORMATION OF THE DIAPHRAGM; AND FOURTH MEANS, INCLUDING SECOND LEVER MEANS COMPRISING A SECOND LEVER DEVICE COMPRISING AND INTERMEDIATE PORTION PIVOTALLY AFFIXED TO SAID FIRST MEANS FOR SUPPORT THEREBY AND COMPRISING A SUBSTANTIALLY FRICTIONS FLEXIBLE MEANS PERMITTING LIMITED MOVEMENT OF A MOVABLE PORTION OF THE SAID SECOND LEVERDEVICE ABOUT A PIVOT ZONE, SAID FOURTH MEANS INTEGRALLY COMPRISING A SECOND TRANSMITTER MEANS INTERCONNECTING SAID FIRST LEVER DEVICE AND SAID SECOND LEVER DEVICE FOR MOVEMENT OF THE MOVABLE PORTION OF SAID SECOND LEVER DEVICE INCIDENT TO MOVEMENT OF THE MOVEMENT PORTION OF THE FIRST LEVER DEVICE, AND THE MOVABLE PORTION OF SAID SECOND LEVER DEVICE CARRYING SAID OTHER OF SAID ELECTRICAL COMPONENTS TO MOVE THE LATTER TO CAUSE RELATIVE MOVEMENT BETWEEN SAID COMPONENTS TO VARY SAID POTENTIOMETER MEANS INCIDENT TO MOVEMENT OF THE MOVABLE PORTION OF SAID SECOND LEVER DEVICE, SAID FIRST AND SECOND LEVER MEANS AND SAID TRANSMITTER MEANS BEING EFFECTIVE TO PROVIDE SUBSTANTIALLY FRICTIONLESS COMPOUND AMPLIFICATION OF THE TRAVEL OF SAID CENTER PORTION OF SAID DIAPHRAGM INCIDENT TO CHANGE OF PRESSURE IN SAID CHAMBER, SAID TRANSDUCER HAVING CHARACTERISTICS SUCH THAT THE NATURAL FREQUENCIES OF MOVABLE PARTS OF SAID TRANSDUCER ARE VERY HIGH AND ARE SUCH THAT SAID TRANSDUCER MAY IN THE COMPLETE ABSENCE OF LIQUID DAMPING MEANS FOR SAID MOVABLE PARTS FURNISH HIGHLY ACCURATE PRESSURE-REPRESENTING SIGNALS OF HIGH PRESSURE IN ENVIRONMENTS INCLUDING ENVIRONMENTS OF INTENSE HIGHFREQUENCY VIBRATION AND ENVIRONMENTS OF VERY LOW AMBIENT TEMPERATURE.
