Rotary drive electrical pulse generator
Abstract
Abstract AN ELECTROMECHANICAL TRANSDUCER ADAPTED TO UTILIZE A MECHANICAL ROTARY INPUT DRIVE FROM A METERING DEVICE AND TO GENERATE A DIGITAL ELECTRICAL PULSE OUTPUT FOR SENSING OR READING AT A STATION REMOTE FROM THE METER. THE ROTARY INPUT DRIVES A GEAR WHICH IS CONNECTED BY A COIL SPRING TO A COAXIALLY DISPOSED ROTATABLE MAGNET ASSEMBLY. A TRIGGER MECHANISM SEQUENTIALLY RESTRAINS THE MAGNET ASSEMBLY TO CAUSE LOADING OF THE COIL SPRING UPON ROTATION OF THE GEAR, AND THEREAFTER RELEASES THE MAGNET ASSEMBLY FOR INTERMITTENT, LIMITED ROTATION IN THE DIRECTION OF ROTATION OF THE GEAR UNDER THE IMPETUS OF THE COIL SPRING. A U-SHAPED CORE WITH COILS THEREON IS POSITIONED WITH THE ENDS OF THE CORE ADJACENT THE MAGNET ASSEMBLY FOR GENERATING AN ELECTRICAL PULSE UPON EACH SUCH ROTATION OF THE MAGNET ASSEMBLY.
