 Zeiger   b),   so findet   sich oberhalb des Ansgangspunktes a die Zahl &alpha;= 1#05, welche mit 6#28   multipliziert die   Grösse   H   H = 6. 69 ergibt.   



   Die mit H bezeichnete Teilung kann auch am beweglichen Sehieberteile angebracht werden.

 minder   geübte   Rechner. 



   Die Anordnung ist so getroffen, dass die zur Ausführung der Rechnung, zur Aufsuchung der Funktionen erforderlichen Einstellungen   und     Ablesungen   nicht dem   Gedächtnisse   eingeprägt werden müssen, dass sich dieselben vielmehr durch entsprechend angebrachte Zeichen an den Einstell- und Ablesepunkten von selbst ergeben. 



     PATENT-ANSPRACHE   :
1. Rechenschieber,   dadurch gekennzeichnet, dass   die   logarithmisehe Normalskala ein-und   ein-   halbmal   auf dem festen Lineale angebracht ist, während die Gegenskala bei gesehlossellem Sehieber um etwa die Hälfte der Länge der Normalskala gegen diese versetzt ist.

 Pointer b), the number α = 1 # 05 is found above the starting point a, which multiplied by 6 # 28 results in the quantity H H = 6. 69.



   The graduation marked H can also be attached to the movable part of the screen.

 less experienced computers.



   The arrangement is made in such a way that the settings and readings required to carry out the calculation and to search for the functions do not have to be impressed on the memory, but rather that they result automatically from appropriately attached symbols at the setting and reading points.



     PATENT APPROACH:
1. Slide rule, characterized in that the logarithmic normal scale is attached one and a half times on the fixed ruler, while the counter scale is offset from the normal scale by about half the length of the normal scale in the case of a closed slide rule.
