  • Patent number: 3955638
    Abstract: A self-restoring precision balance which is essentially non-deflecting. Initially, the balance is unbalanced by an amount approximately equal to one half its weighing range, and the electrically energized restoring system is so arranged that a restoring force, is exerted in one direction to maintain the beam at a null condition at loads less than about one half scale, and is exerted in the opposite direction to maintain the beam at a null condition at loads greater than about one half scale. Heating in the restoring transducer is therefore reduced by a factor of 4. A unique arrangement of cross-flexures and a stabilizing band which remains always in tension, is used without affecting the accuracy of the balance, because of the small range of movement of the self-restoring system. A unique two coil electro-magnetic restoring arrangement provides for linearity at low cost.
