PATENTAMT.PATENT OFFICE.
In den Patentschriften Nr. 75503 und 92490 ist ein direkt zeigender Widerstandsmesser beschrieben, bei welchem ein nicht homogenes Magnetfeld mit relativ zu demselben beweglichen Stromspulen Verwendung findet, zum Zweck, zwei einander entgegengesetzte und von der Lage des beweglichen Systems abhängige Drehmomente zu erhalten. Derselbe Zweck kann auch erreicht werden dadurch, dafs man ein mehr oder weniger homogenes Feld von relativ geringer Ausdehnung mit dagegen beweglichen, verhältnifsmäfsig grofsen Stromspulen combinirt, die nach und nach in dasselbe eintreten und hierbei ebenfalls zu - einer mit der Lage des beweglichen Systems veränderlichen Kraftwirkung Veranlassung geben.A direct-pointing ohmmeter is described in patent specifications No. 75503 and 92490, in which a non-homogeneous magnetic field with relative to the same moving current coils is used, for Purpose, two opposing and dependent on the position of the moving system To obtain torques. The same end can also be achieved by creating a more or less homogeneous one Field of relatively small extent with, on the other hand, mobile and comparatively large Combined current coils, which gradually enter the same and thereby also to - give rise to a force that changes with the position of the moving system.
Die Fig. 1., 2 und 3 zeigen derartige Anordnungen, und zwar Fig. 1 ein bewegliches System, gebildet aus zwei bogenförmigen Spulen, die auf einer Aluminiumscheibe befestigt sind und sich relativ gegen das kreisförmige feste Feld M bei Drehung um die Achse α bewegen können. Beide Spulen sind entsprechend den Ausführungen in der Patentschrift Nr. 75503 geschaltet und werden von dem festen Felde abgestofsen; das letztere liefert ein kräftiger Hufeisenmagnet mit cylindrischen Polschuhen. Die äufsersten Lagen des Systems sind dadurch gekennzeichnet, dafs sich die Mitte der einen oder der anderen Spule im festen Felde be-Figs. 1, 2 and 3 show such arrangements, namely Fig. 1 a movable system formed from two arc-shaped coils which are mounted on an aluminum disc and move relatively against the circular fixed field M when rotated about the axis α can. Both coils are connected as described in patent specification no. 75503 and are repelled by the solid field; the latter is provided by a powerful horseshoe magnet with cylindrical pole pieces. The outermost layers of the system are characterized by the fact that the center of one or the other coil is in the fixed field.

fi'ndet. Fig. 2 zeigt eine der vorigen ganz ähnliche Anordnung, nur sind die bogenförmigen Spulen durch halbkreisförmige ersetzt. In Fig. 3 endlich besteht das bewegliche System aus zwei langen, gekreuzten Spülen, die von einem ebenfalls langen, schmalen, festen Felde abgestofsen werden; hierbei kann auch die eine Spule, z.B. s.2, durch zwei kürzere, auf beiden Seiten von S1 angeordnete ersetzt werden. Dadurch wird ein Uebereinanderlegen der Spulen vermieden und das Interferrikum kann enger genommen werden. In den äufsersten Stellungen befindet sich entweder S1 oder s.2 seiner ganzen Länge nach im Felde M. Der dies Feld erzeugende Hufeisenmagnet erhält zwei schmale rechteckige Polschuhe.finds. Fig. 2 shows an arrangement very similar to the previous one, only the arc-shaped coils have been replaced by semicircular ones. Finally, in FIG. 3 the movable system consists of two long, crossed sinks, which are repelled by an equally long, narrow, solid field; In this case, one coil, for example see FIG. 2 , can also be replaced by two shorter ones arranged on both sides of S 1. This avoids laying the coils one on top of the other and the interferric can be made closer. In the outermost positions, either S 1 or S 2 is located along its entire length in the field M. The horseshoe magnet that generates this field has two narrow, rectangular pole pieces.
