Abstract
1330592 Electrical Weighing Apparatus METAL DETECTION LTD 30 June 1971 30561/71 Heading G1N A weighing machine includes a belt 1 carrying a load over a weighbridge including a roller 3 of which the deflection under load is sensed by a differential transformer 8,9,10,11 the energizing signal for which is a function of speed of travel of the belt and comes from a multiplier 12 connected to tachogenerator 14 and A.C. generator 13, so that a voltage U tapped at wiper 21 from potentiometer 17 across the transformer winding 11 and rectifier diodes 16 is dependent on the product of belt speed and load, and a voltage U H across resistor 19 is dependent on belt speed alone. With no load on the belt voltage U representing tare weight is fed via triple throw switch 40 set at station II to an integrating motor 23 as also is voltage U H via switch 30 and the sum voltage U 3 is integrated over a given number of belt rotations and displayed by a mechanical counter 24. The switches are then set to station III so that only the voltage U H is integrated for a given number of belt rotations to obtain a second reading on the counter. The second reading should then be in the same ratio to the first as the ratio of the numbers of belt rotations for the two readings. If not, the wiper 21 is adjusted and the process is repeated until the ratios are equal when tare weight compensation has been effected. To complete the calibration of the machine a weight of known magnitude is weighed and the resultant voltage output to the integrating device is determined,
