    Abstract: The load-weighing apparatus faultlessly detects even smallest load variations in the lower load range. For this purpose wire strain gauges are mounted at structural parts or components of the elevator car and these structural parts or components are subjected to bending under the load to be weighed. The wire strain gauges are interconnected to form a bridge circuit. An amplifier circuit is connected at the output side of the bridge circuit and has a higher gain in the lower load range. When an input voltage corresponding to a predetermined load occurs at the amplifier circuit, the gain of the amplifier circuit is switched to a lower value. It is thus possible to detect loads throughout a greater range of loads.

  • Patent number: 4073355
    Abstract: A weighing device for the automatic regulation of a crystal-growing operation includes an upright shaft on which a crucible for a crystal melt is supported. The shaft is journalled for rotation and has limited freedom of movement in downward direction under the weight of the crucible and the melt therein. Weight-responsive signal-generating devices are engaged by the shaft or components associated therewith, so that pressure is exerted upon these devices to different degrees, in dependence upon the weight of the melt in the crucible. These devices produce signals as a function of the weight acting upon them, and these signals in turn control the crystal-growing operation. The shaft is rotatable by a drive arrangement which does not require physical contact with the shaft to rotate the same.
