Single axis integrating accelerometer

Claim 1

AN INTEGRATING ACCELEROMETER COMPRISING A RELATIVELY FLAT MASS HAVING A LENGTH AND WIDTH CONSIDERABLY GREATER THAN ITS THICKNESS, SAID MASS HAVING LOW ELECTRICAL RESISTIVITY, SPRING MEANS FOR SUSPENDING THE MASS FOR DEFLECTION ALONG ONE SENSITIVE AXIS ONLY AND PREVENTING DEFLECTION ALONG OTHER AXES, SAID SPRING MEANS NORMALLY SUPPORTING THE MASS IN A NEUTRAL POSITION, CIRCUMFERENTIALLY POLARIZED SUBSTANTIALLY CYLINDRICAL MAGNETIC MEANS FOR PRODUCING A CONCENTRATED MAGNETIC FLUX THROUGH SAID MASS AT THE NEUTRAL POSITION AND ENERGIZABLE TO VARY THE RATE OF CHANGE OF MAGNETIC FLUX AT SAID POSITION, POSITION TRANSDUCER MEANS RESPONSIVE TO THE DISPLACEMENT OF SAID MASS FROM SAID NEUTRAL POSITION, FOR DETERMINING DEFLECTION OF SAID MASS FROM SAID POSITION ALONG SAID SENSITIVE AXIS, AND ACTUATING MEANS ENERGIZED BY SAID TRANSDUCER MEANS FOR ACTUATING SAID MAGNETIC MEANS TO VARY THE RATE OF CHANGE OF FLUX AT SAID NEUTRAL POSITION RESPONSIVELY TO DEFLECTION OF SAID MASS FROM SAID NEUTRAL POSITION, SAID ACTUATING MEANS BAING ADAPTED TO ROTATE THE MAGNETIC MEANS AT A SPEED PROPORTIONAL TO THE DISPLACEMENT OF THE MASS, WHEREBY SAID MASS IS RESTORED TO SAID NEUTRAL POSITION BY A MAGNETICALLY GENERATED FORCE EQUAL TO AN OPPOSITE THE ACCELERATION FORCE ACTING UPON SAID MASS.
