Abstract: An electromagnetic force-compensating weighing appliance has at least two levers engaged at one of their ends in supporting relationship to a load scale, and each connected at their other ends to a respective compensating coil, the compensating coils being symmetrically disposed in the air gap of a single magnet unit, and the levers being pivotally supported between their ends on fixed supports.

Abstract: A flat weighbridge has a load platform supported by either two one-armed or two two-armed levers arranged at least partly beneath the load platform, wherein one lever is bifurcated to define two spread apart sides and each of the sides bears a supporting device for the load platform, while the other lever bears only one supporting device for the load platform.

Abstract: An overload protection device for a top pan precision scale having a weighing pan support and a support plate carried by a load support mounted for limited movement and connected to an indicator, includes a spring engaged between the weighing pan support and the support plate whereby the weighing pan support is resiliently coupled to the load support, and a plurality of overlapping elements carried by the weighing pan support and extending beyond the outer peripheral edge of the support plate in close proximity thereto so that the weighing pan support and support plate are held in assembled relationship against the bias of the spring by the overlapping elements at the outer peripheral edge of the support plate, whereby upon eccentric loading of the scale, the pivot point of the weighing pan support is extended to the side of the weighing pan support opposite the load, and the lever translation thus effected results in a lower load on the load support than the highest available load.

Abstract: A calibratable electromagnetically compensating precision balance having a weighing and taring device, in the form of a pan support, is provided with a parallel guide. The output from the balance is fed to an analog-digital converter which has its output coupled, via a minicomputer (calculator), to a display. A reference weight is provided for the balance. The reference weight is externally switchable for its weight determination, i.e., from outside the housing of the balance. A lifting mechanism is provided to lift the pan from the support. A method for compensating the parameters of the above-described calibratable electromechanical balance which can influence sensitivity and accuracy, involves determining and recording the actual value (M) of reference weight, under the prevailing operating conditions using the balance. Forming a quotient from the actual measured value (M) and the set (given) value (m) of the reference weight, the quotient being expressed in the form of a factor (F).

Abstract: An electromagnetically compensating beam balance has a balance housing, a am and a fixed counterweight. Weight changing means, which change the weighing range (scale) by substitution, are provided on the load receiving side. A parallel guidance system is provided. Rods which accept only horizontal forces are coupled between a load carrier and the housing. Vertical flexure elements, which accept vertical forces, are coupled between the beam and the load carrier.
