摘要： An overload protection device for a top pan precision scale having a weighing pan support and a support plate carried by a load support mounted for limited movement and connected to an indicator, includes a spring engaged between the weighing pan support and the support plate whereby the weighing pan support is resiliently coupled to the load support, and a plurality of overlapping elements carried by the weighing pan support and extending beyond the outer peripheral edge of the support plate in close proximity thereto so that the weighing pan support and support plate are held in assembled relationship against the bias of the spring by the overlapping elements at the outer peripheral edge of the support plate, whereby upon eccentric loading of the scale, the pivot point of the weighing pan support is extended to the side of the weighing pan support opposite the load, and the lever translation thus effected results in a lower load on the load support than the highest available load.

摘要： In an electromechanical weigher to be used in areas subject to explosion hazards, the electronic indicator ledge and the weigher apparatus or weighing system is constructed explosion proof in an intrinsically safe manner, and the power supply in the case is on all sides partitioned by means of bulkheads, and the free space enveloping these constituents is filled with an explosion-impeding granulate e.g. of quartz. For the use as dosing weigher for prescription weighings in such areas subject to explosion hazards, the indicator ledge is constructed by means of a hollow support engaging the case above the weigher dish and above a tare vessel of the usual height to be put on the weigher dish, as horizontal indicator constituent running approximately parallel to the weigher back, and the indicator constituent is tiltable at the support about a horizontal shaft in which structure the electric supply lines are passed from the indicator edge through the hollow support, into the inside of the case. The indicator constituent is furthermore provided with switches and operating keys which together with the indicator ledge ae explosion proofed in an intrinsically safe manner. For school and demonstration purposs, the indicator constituent is provided with two synchronically connected electronic indicator ledges, one pointing to the frontside and one to the backside of the weigher, which indicator ledges are arranged in a mutually parallel position inside the indicator constituent.
