  • Patent number: 4573542
    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: 4306637
    Abstract: A shoe or friction brake having the brake levers thereof connected both at the pivotably mounted end and also at the end driven by a brake spring mutually independently of one another at the brake housing. The pivotably mounted end is connected with the brake housing by elements which have a resilient or spring action perpendicular to the direction of action of the brake spring. These resilient elements are in the form of plate springs and/or a leaf or blade spring. The bearing means for each brake lever is arranged between the plate springs. Each brake lever has operatively associated therewith a choke or reactance coil, and the choke yoke or the like is arranged at the bearing means and the choke core at the brake housing. With the brake levers located in their braking position the latter, when subjected to load, are movable perpendicular to the direction of action of the brake springs, so that the air gaps of the choke coils can be reduced or increased in size, as the case may be.
