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.

Abstract: A system for concomitant scenario topography with the aid of a digital computer such that a two-dimensional or three-dimensional map is produced and displayed which illustrates the combined effects, particularly geo-environmental, of multiple, diverse criteria and factors relative to uniquely-referenced, uniform, small areas of a plane surface or the surface of a solid. The topography system employs plural interrelated tables, worksheets and mapping systems to receive, contain and apply various political, economic, scientific, and technical criteria and factors as attributes of a particular small area, and subsequently map the processed data. Each table includes at least one join field which links that table to at least one other table or worksheet. At least one worksheet includes capability for rapid, dynamic user-interaction to facilitate generation of a myriad of actual or imagined scenarios.
