  • Patent number: 5090494
    Abstract: A balance with a system carrier (1) fixed to the housing and with a balance-scale support part (2) connected by two upper and two lower guide rod struts in the form of a parallel guide to the system carrier. Each upper guide rod strut is connected to a lower guide rod strut via two connection areas, which struts are combined to a guide rod plate (5,6). The two guide rod plates (5,6) are fastened laterally to the system carrier (1) and to the balance-scale support part (2). The system carrier (1) is wider than the balance-scale support part (2). The two screw attachment surfaces for the guide rod plates (5,6) on the system carrier (1) and on the balance-scale support part (2) form an angle with one another so that the system carrier (1), the two guide rod plates (5,6) and the balance-scale support part (2) form a trapezoid when viewed from the top.

  • Patent number: 4964478
    Abstract: An electronic balance with scale on top and with parallel guide rods whereby corner-load errors can be corrected by means of the inclusion of at least one leaf spring which is fastened to a load receiver and is supported on the other end on a fixed point of the housing. The magnitude of the correction can be adapted to the corner-load error of the unadjusted parallel guide by means of the selection of the spring stiffness of the leaf spring and/or by means of its effective length.

  • Patent number: 4401176
    Abstract: Electronic weigher apparatus is disclosed which utilizes a plate situated below the weighing scale and above a load receiver which is part of an electronic weight measuring system. The plate is shaped in such a way that thermal air currents generated by the electronic apparatus are carried through a low air resistance path from the interior to the exterior of the weigher casing while a high resistance airflow path prevents air currents from being carried upward from the electronic apparatus to the weighing scale. A collar encircling the scale prevents external air currents from disturbing it during the loading operation.
