Title: Digital weighing apparatus

Filed: 1973-10-02
Abstract: 1422435 Measuring weight electrically; measuring voltage SHINKO DENSHI KK 2 Oct 1973 [14 Oct 1972] 46024/73 Headings G1N and G1U Weighing apparatus including an analogue transducer 9 and a digital voltmeter 13 is automatically connected for unladen zero-shift error by an integrator 15 arranged to alter the voltmeter reading when driven by a calculator 14 in response to a first voltmeter signal representing the sign of the displayed number and a second signal present only when the displayed number lies within a predetermined small range. The calculator 14 may be a circuit, Fig. 3, having two imputs 22, 26 and an output 24. Direct voltages of zero and +5 volts corresponding to a negative and a positive zero shift respectively, when applied to the first input terminal 22, are arranged by design to produce outputs at terminal 24 of-2v and +2v respectively. A shift within the predetermined correction range earths the second input terminal 26, cutting off the transistor 23, while a true zero, or a shift of greater magnitude than the predetermined range, applies +5v to terminal 26 causing the transistor 23 to earth the output terminal 24. The integrator may be a motor 15, coupled to a spring 16 to displace an unladen balance beam 2. Displacement causes the differential transformer 9, excited by an alternator 10, to produce a change in signal which, after rectification at 11, is fed to the voltmeter 13, the change being such as to cause the erroneous reading to regress towards zero. In a weighing operation, however, the voltmeter input signal in response to the application of a load 12 causes the voltmeter display to advance so rapidly as to pass beyond the predetermined correction range before the integrator can act, so that no further shift in the corrected zero occurs during the weighing. If the unladen zero reading drifts beyond the predetermined correction range, a manual correction will be necessary until the automatic correction takes over. The integrator may alternatively be an electrical circuit 27, Fig. 4 coupled directly to the voltmeter input in opposition to the incoming transducer signal. Other measuring mechanisms (e.g pendulum, load cell and force-balance) and other transducers (e.g. strain gauge, magnetostriction and photocell) are disclosed as being suitable to the application of the invention.
