Continuous proportioning of components of mixture - uses computer monitoring variations in weight of supply bins and comparing with programmed weights

摘要

The mixture proportioning method uses a computer (X) to compare weights of the mixtures constituents. The weight of the constituent is determined by a comparison with data furnished by a programme. This programme gives the variation law fixed for the particular comparison. Any variation detected is amplified to control the flow regulation of the mixts. constituents to arrive at the desired mixt. composition. The comparison between each weighed constituent of the mixt. and the weight corresp. to the programme is obtained during short time intervals. The system has a series of bins (A, B, C) contg. the constituents. It has means for monitoring the weight of each of the bins.
