Abstract
780,364. Electric weighing systems. GERONDEAU, J. July 13, 1955, No. 20226/55. Class 40 (1). In an automatic weighing scale a counterweight 12 is automatically moved along a beam 1 to counterbalance the weight of a load suspended from a knife edge 8, by a pinion 21 which engages a rack on the counterweight at a point concentric with the beam fulcrum 6, and which is driven in accordance with the out-of-balance of the beam as detected by switches 35-38. Switches 35, 37 control rotation of motors 23, 24 in one direction, while switches 36, 38 control their rotation in the reverse direction, the shafts of these motors 23, 24 being connected respectively with a sun wheel 29 and the planet carrier 28 of a differential gear, the output shaft 22 of which carries the pinion 21. In operation, with a large out-of-balance condition switches 35, 37 are both closed and the counterweight moves at a high speed until, near the point of balance, switch 37 opens and stops motor 24 so locking the planet carrier and producing a reduced speed during the final balancing movement of the counterweight. The shaft 22 is connected to a weight indicator, recorder or integrator; or a sorting device. A tare weight is suspended from knife edge 10.
