Verfahren zur Begradigung des Kurvenverlaufs bei logarithmisch ausgelegten Potent iomet er-fVi der stand 3p tat ten Procedure for straightening the curve with a logarithmically designed potentiometer er-fVi der stand 3p tat th
Bei heute üblichen Potentiometern erfolgt die hersteIlungsmäßige Abstimmung einer kreisringförmigen Widerstandsbahn bevorzugt mit dem Ziel, derWith potentiometers that are customary today, the production tuning of a circular resistance track is preferably carried out with the aim of

entweder einen linearen oder aber einen logarithmischen Vertauf zu geben.to give either a linear or a logarithmic value. Mit R ist der Widerstand, mit B der Regelwinkel bezeichnet, der im allgemeinen zwischen O und etwa 270 variiert werden kann.The resistance is denoted by R and the control angle is denoted by B, which can generally be varied between 0 and about 270.
Die Erfindung betrifft die" Glättung des logarithmischen Verlaufs. SieThe invention relates to the "smoothing of the logarithmic curve. You wird nachstehend für kreisringförmige Bahnen beschrieben, gilt Jedochis described below for circular orbits, however in sinngemäßer Abänderung ebenso für geradlinig verlaufende Mittel linienwith a corresponding modification also for straight center lines von Potentiometer- oder Trimmmr-Widerstandsbahnen.of potentiometer or Trimmmr resistance tracks.
Aus hersteIlungstechnischen Gründen uriierteiIt man den gesamten Regelwinke Ibereich von etwa 270 in einige Abschnitte und sorgt beim Spritzen oder Siebdrucken Jedes Teilabschnities dafür, daß Jeder Übergang von einem zum anderen Abschnitt möglichst "glatt" in mechanischer und elektrischer Hinsicht verläuft. Trots sorgfältigen Arbeiten» in der letztgenannten Hinsicht ließ *s sich Jedoch nicht vermeiden,, daß der Gesamtfunktionsverlauf Unstetigkai ten aufwies, etwa derarta wie sie durch die linke Kurv in Fig. 2 versinnbiIdlicht werden, in dieser Fig. ist die horizontale Achse (Winkel B) im linearen, die vertikale Achse' (R-Werte) im~ logarithmischen Maßstab -untärtei Ii. ; " For manufacturing reasons, the entire control angle range of about 270 is divided into a few sections and, when spraying or screen printing each section, it is ensured that each transition from one section to the other runs as "smoothly" as possible in mechanical and electrical terms. Trots careful work "in the latter respect, let * s can not be avoided, however ,, that the total function curve having ten Unstetigkai, about such a as they are versinnbiIdlicht through the left Kurv in Fig. 2, in this FIG., The horizontal axis (angle B) in the linear, the vertical axis' (R-values) in the logarithmic scale -subparti Ii . ; "
