Abstract
1428024 Displacement encoder: weighing balance ETABS LEONARD SA 30 March 1973 [31 March 1972] 15475/73 Headings G1A and G1W Weighing apparatus comprises a moveable member 3, Fig. 1, supporting a pan 2, the member 3 being supported in a parallelogram system comprising knife edge bearings 7, 9, 8, 10, the movement of the member 3 being compensated by a spring A, and this member also carrying a displacement encoding scale 6 which moves in front of photo-detectors 5 to provide counting pulses, and further comprises a resilient member 13 Fig. 2 attached directly at one end to the member 3 and via spring 16 to a fixed frame 1 of the apparatus and acting to press scale 6 against a fixed plate 15 to thereby maintain the distance between the scale 6 and head 5 constant. No motion amplifying devices are included between member 3 and scale 6.
