    摘要: The invention suggests for an electronic balance with a balance scale (1), with a parallel guide for the balance scale (1), with at least one sensor which measures the torques transferred from the balance scale (1) to the parallel guide, with storage means in the electronic circuitry of the balance in which means the magnitude of the corner-load inaccuracies of the parallel guide is stored in the form of corner-load correction factors and with switching means or program parts in the electronic circuitry of the balance which correct the weight value outputted from the measuring system on the basis of the output signals of the sensor or sensors and of the stored corner-load correction factors that controllable signals (10-13) are provided which designate the corners and sides of the balance scale (1). The signals can be formed by light sources adjacent to the balance scale (1) or in the corners or on the sides of the display field (9). The use of individual segments of the 7-segment numbers (3) of the balance display is preferred. An operator control can be achieved with these signals when readjusting the corner-load freedom of the balance.

    摘要: In a parallel rod guide for electronic balances having a measured value sensor, typically corner load adjustments are made by adjusting the parallelism of the two rods and such adjustments are normally sufficient. However, this can eliminate only linearly load-dependent corner load errors. In order to eliminate corner load errors which are non-linearly dependent on the load, the present invention provides an adjustment assembly which varies the resilience of the fastening points on the system carrier side of at least one rod to horizontal forces. The adjustment assembly may comprise, a screw/nut connection whose position can be varied vertically therewith, varying the effective length of a resilient intermediate part.

    摘要: The invention discloses an electronic balance comprising a measured value receiver (23) and an electronic evaluation unit (14) having a digital display (10) and an analog display (6), whereby both displays are controlled by the electronic evaluation unit (14). A digital input keyboard (12) is used for inputting the set weight value of a loading. The electronic evaluation unit (14) contains a memory (15) and an arithmetic unit (16) which permit the values indicated in the digital display (10) and in the analog display (6) to be differentiated against each other by the amount stored in the memory (15) so that during a loading procedure the digital display (10) runs from the negative set weight value to 0g and the analog display (6) from 0% to 100%. The analog display (6) consists of adjacent bars (7) which can be shited in their lightness, whereby the length of the individual bars continuously decreases from 0% to 100% of the set weight value, and continuously increases again over 100% of the set weight value.

    摘要: In known methods of initializing a balance with counting scale a given quantity of the pieces to be counted is placed on the balance at the same time and the average individual weight is calculated therefrom and used as a base for the following piece counts. In contrast thereto, the invention suggests that the pieces be placed individually on the balance and that the standstill of the balance be waited for after each placing of a piece. This makes it possible to also calculate the standard deviation in addition to the average value and statements concerning the counting precision can be made which are based on known statistical laws, so that counting errors can be avoided.

    摘要: A cardioplegic controlling and regulating device for the dosed perfusion of cardioplegic perfusion solution in open-heart surgery has a storage container for receiving the cardioplegic solution, which container is part of a scale and can be connected to the heart over a tubular conduit. A pressure-controlled dosing pump which acts on the tubular conduit and cooperates with a second, reversible pump which is constructed as an exhaust pump and is selectively operable synchronously or asynchronously within controllable tolerance limits with the first dosing pump during the perfusion and sustaining of the perfusion. An ultrafilter for the mixture of blood and cardioplegic solution removed from the patient's heart is located in a removal line. An outlet for the blood separated form the ultrafilter is connected by a conduit to a blood storage container and the permeate or filtrate outlet of which ends in a filtrate line or in a filtrate collector vessel. The ultrafilter is located in a by-pass line to a blood storage container so that the patient's blood mixed with cardioplegic solution can be prepared to a hemoconcentrate after the perfusion has been completed. In the same manner, other blood removed by suction from the patient during the operation can be prepared by this by-pass line and the ultrafilter. Another pressure-controlled dosing pump sustains the first dosing pump and is connected to it in parallel.

    摘要: It is known in high-resolution electronic weighing scales based on the principle of electromagnetic force compensation that the load-dependent development of heat in the coil and the precision resistor can be compensated by sending an additional alternating current through the coil and the precision resistor which is complementarily regulated in its amplitude. In order to make possible a precise regulation of the amplitude of the additional alternating current even in the case of a small carrying force of the electromagnetic force compensation and of a correspondingly small direct compensating current, the invention proposes connecting in a voltage divider in parallel to the coil and the precision resistor which has a highly temperature-dependent resistor. In this parallel branch direct and alternating current are higher by a constant proportionality factor than in the main branch formed by coil and precision resistor. The parallel branch is also part of a resistance measuring bridge which regulates the amplitude of the additional alternating current in such a manner that the highly temperature-dependent resistor retains its theoretical excess temperature and therewith its theoretical resistance value.
