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.

Abstract: Pressure measuring apparatus with electric force compensation has a magnet coil system exerting a counterforce on a pressure sensor. The system has at least two magnet coils which are controllable independently of each other. One magnet coil is for balancing a preliminary load and the second magnet coil is for balancing the force to be determined. The second coil is connected to a control circuit provided with a system for sensing the position of the sensor and a system for sensing the current required to balance the preliminary load. Once the preliminary force is balanced by one coil further applied force is measured by the current in the other coil.

Abstract: An electromagnetically-compensated balance of the type including load and reference compensation coils for returning load and reference assemblies to their neutral positions relative to the balance housing, characterized in that the reference compensation coil is connected in series with reference current regulating means to define a series branch that is connected at one end with one terminal of a direct-current voltage source. Electronic switch means alternately connect the other end of said series branch in series with, and disconnect said other end of said series branch from, said load compensation coil and said voltage source, respectively. The reference current regulating means are operable by a reference control voltage as a function of the displacement of the reference assembly from its neutral position, and the electronic switch means are operable by a load control voltage to effect series connection between said load and reference compensation coils for time periods that correspond with the displacement of the load assembly from its neutral position. Buffer means are provided for effecting a galvanic coupling between the load and reference coil switching circuits, and stabilizing means-such as a dummy load or a catching diodeare provided for stabilizing the switching operation.

Abstract: A device for indicating the weight of an object is disclosed herein and includes a first circuit for producing an oscillatory excitation signal which is capacitively coupled to a second circuit for producing at the output of said second circuit a signal indicative of the weight of said object. In this regard, the second circuit is capacitively coupled to the first circuit by a coupling plate mounted to a support member for movement in response to the weight of said object. This output signal is applied to an electromagnetic assembly which, in response thereto, applies to said coupling plate a proportional force which is equal and opposite to the gravitational force of the supported object for terminating movement of said coupling plate. In this manner, the output signal may be monitored for indicating the weight of said object.
