Abstract: In a three force balanced mechanism comprising a floating pivot, an input force transmitting member, a feedback force transmitting member, one end of the input force transmitting member and one end of the feedback force transmitting member pivot in different directions, a flexible span setting member inclined with respect to the input force transmitting member, one end of the flexible span setting member being wound about or unwound from the floating pivot, there are provided detecting means for detecting the input force, restoring means responsive to the output of the detecting means for applying a restoring force to the feedback force transmitting member, and spring means for varying a force acting upon the input force transmitting member or the feedback force transmitting member in accordance with the movement of the free end of the span setting member. With this improved meter zero point shift can be automatically compensated for thereby eliminating zero point adjustment at the time of varying the measuring range.

Abstract: For the automatic weighing of a beam balance with electromagnetic force compensation, substitution control weights and digital recording are used. An indicator signals the position of balance beam to a microcomputer. The load compensation is carried out with a limited number of variable electromagnetic compensation forces of constant amplitude, which are produced by means of a corresponding number of discrete constant currents. The currents are graded according to decreasing powers of a numerical system of a suitable basis; as a rule, just like decimally organized figures according to units and powers of ten of these units. Starting out from upper to lower decades, a count is made in each decade as to how many compensation units are needed in order to overcompensate the load. For this purpose, a decision is made merely in the case of every compensation step--without determining precisely the rest position of the balance beam--as to whether the load applied is larger or smaller than the compensation force. Whenever the indicator signals an overcompensation, then the preceding counting step is regarded as the weighing result of this decade. Numerical correction values are assigned to each compensation step of each decade. The weighing results develops from the sum of the weighing results of all decades and the sum of correction values which had been assigned to the evaluated compensation steps of each decade.

Abstract: A flexure in a force transducer, as an inertial guidance accelerometer, for securing a force sensitive element to a mounting base includes one or more flexure sections having one or more recessed surfaces which are substantially coincident with the neutral bending plane of the flexure. Electrically conductive coating on the recessed surfaces provide electrical connections to components located on the force sensitive element. The conductive coatings on or near the neutral bending plane of the flexure sections minimizes bending moments caused by stresses set up between the conductive coatings and the flexure which may in turn lead to bias errors. At the same time, the flexure configuration provides for the desired strength and spring rate for the force sensitive element.

Abstract: A measuring funnel for determining the tension of slivers includes a stationary component having a funnel-shaped inlet opening and a movable component. The bore for the passage of the sliver continues in the movable component, and may have a section along which it continues to taper. The passage of sliver thereby exerts a force on the movable component in the direction of its travel. This force is compensated by pneumatic or electrical means, so that the movable component takes a balanced position for every sliver cross section. These balanced positions are then converted into corresponding signals by means of electrical or pneumatic sensors, which signals are either used for measuring the absolute sliver cross section or for regulating the sliver cross section to a set value.

Abstract: A closed loop control system for maintaining a force transducer assembly in a balanced position is disclosed. The control system has a feedback loop control circuit for providing a force rebalance signal at one of a plurality of predetermined discrete amplitude values during each of a plurality of successive equal duration time intervals. The signal has a constant amplitude during each interval. The control circuit further provides a respective digital representation for each amplitude value of the rebalance signal for each of the successive time intervals. Thereby, a precise determination of the value of the time-force product can be generated with the concomitant determination of the forces acting upon the force responsive transducer. The control system is particularly useful for non-linear transducers, such as square law devices where the time-force product is difficult to determine with continuously variable amplitude values.
