Title: Improvements in acceleration responsive devices
IPC: G01P15/13
Filed: 1955-12-09
Abstract: 828,611. Electric indicating systems. GENERAL ELECTRIC CO. Dec. 9, 1955 [Dec. 29, 1954], No. 35444/55. Addition to 816,779. Class 40 (1). In an accelerometer of the type claimed in Claim 2 of the parent Specification wherein rotation of unbalanced drum 10 in response to accelerating forces is detected by a moving coil assembly 20 and wherein a counter torque to restore the drum is applied by an internal stator and rotor assembly 16, 17, at least part of the unbalance mass is mounted on a support which is resilient with respect to the direction of the acceleration to be detected. As shown, the unbalance mass 15 is mounted on a leaf spring 16 the other end of which is secured to a bracket 17. Attached below mass 15 is a coil 20 which changes position in response to acceleration in the manner shown in Fig. 4. The coil is associated with a magnetic circuit which is A.C. energized and produces an output signal in response to its displacement from alignment with this circuit. This signal is amplified and feeds meter 30 to provide a restoring torque as described in the parent Specification. Pick-off coil 20 will be deflected in response to the acceleration a greater amount than mass 15 because of the flexure of the strip. Thus when the restoring torque has restored mass 15 an output signal will still be derived from coil 20 which will be constant while the acceleration remains unchanged. Thus the angular position of drum 10 is held unchanged.
