摘要： 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.

摘要： 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.
摘要翻译：一种电子天平，具有在顶部和平行的引导杆上的刻度，由此可以通过包括至少一个固定到负载接收器的板簧来校正角负载误差，并且另一端支撑在固定点住房。校正的大小可以通过选择板簧的弹簧刚度和/或通过其有效长度来适应未调节的平行导轨的角负载误差。

摘要： 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.
摘要翻译：与系统载体（1）的平衡，该系统载体（1）固定到壳体上，并具有平衡尺度的支撑部分（2），该两个上部和两个下部导杆支柱以平行引导件的形式连接到系统载体。每个上导杆支柱经由两个连接区域连接到下导向杆支柱，该支柱组合到导杆板（5,6）。两个导杆板（5,6）横向固定到系统托架（1）和平衡秤支撑部件（2）上。系统载体（1）比平衡秤支撑部分（2）宽。系统载体（1）和平衡秤支撑部分（2）上的导向杆板（5,6）的两个螺钉附接表面彼此形成一个角度，使得系统载体（1），两个当从顶部观察时，导杆板（5,6）和平衡秤支撑部分（2）形成梯形。
