Abstract: 981,055. Weighing-apparatus. BADISCH ANILIN-& SODA-FABRIK A.G. May 2, 1963 [May 5, 1962], No. 17330/63. Heading G1W. [Also in Division G3] A weighing apparatus comprises a conveyer belt 2 on to which material is fed by a vibrating shoot 24 from a container 25, counterbalanced by a weigh beam 13 about a pivoting axis 12. The conveyer belt is supported by rollers 3, 4 in a frame 1, the rollers being driven by a motor 9 through gearing 26. The weigh-beam 13 has sliding weights 14, 15 and movement is damped by an eddy-current device 20 and detected by a differential transformer 21, the output of which has a phase-shift of 180 degrees about a zero-position. The output of the transformer is fed to a regulator 22 which controls a servomotor positioning a control resistance of the vibrating shoot 24 through a slip coupling. The balance is pivoted by cross-bands 28 and arranged in a Z-form as shown, the conveyer belt being separated from the weigh-beam by a partition 16 which forms with a wall 17 a chamber 19 which is pressurized, to exclude dust, through an opening 18. The upper section of the belt conforms to the shape of a supporting trough and the lower section is flanked by a guard plate Fig. 3, not shown.
