Accelerometer

Claim 1

IN COMBINATION WITH A MAGNETIC MATERIAL MASS AND A PAIR OF ELECTROMAGNETS COAXIALLY DISPOSED ON OPPOSITE SIDES OF SAID MASS AND IN NON-OVERLAPPING RELATIONSHIP WITH SAID MASS, A SOURCE OF ELECTRIC POWER AND A DIFFERENTIAL RHEOSTAT BETWEEN SAID SOURCE AND THE INPUT ENDS OF WINDINGS AROUND THE OPPOSED POLES OF SAID ELECTROMAGNETS FOR MAGNETICALLY SUSPENDING SAID MASS FREELY IN SPACE SUBSTANTIALLY AXIALLY BETWEEN SAID POLES, SAID ELECTROMAGNETS CONSTITUTING THE SOLE SUPPORTING MEANS FOR SAID MASS, A VARIABLE RHEOSTAT BETWEEN SAID OUTPUT ENDS OF SAID WINDINGS AND SAID POWER SOURCE, A DEVICE FOR MEASURING AND INDICATING AXIAL COMPONENTS OF FORCES AND ACCELERATIONS IMPOSED UPON SAID MASS BETWEEN SAID ELECTROMAGNETS AND INCLUDING A SENSING DEVICE, A DETECTOR AND AN AMPLIFIER COUPLED IN TANDEM WITH SAID SENSING DEVICE, A MEASURING AND INDICATING DEVICE COUPLED WITH SAID AMPLIFIER AND A SECOND PAIR OF WINDINGS COUPLED TO THE POLES OF SAID ELECTROMAGNETS AND TO SAID AMPLIFIER, THE SENSING AND DETECTING MEANS IN CONJUNCTION WITH EACH OTHER BEING ADAPTED TO GENERATE ELECTRICAL SIGNALS OR PREDETERMINED MAGNITUDE, FREQUENCY AND PHASE TO CONTROL THE AMPLIFYING MEANS, WHICH IN TURN, CONTROLS THE ELECTROMAGNETS, THE WHOLE OPERATING AS A SYSTEM TO CONTROL MEASURE AND INDICATE AXIAL MOVEMENTS OF SAID MASS BETWEEN THE ELECTROMAGNETS.
