Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der durch Patent Nr. 75503 geschützte direkt zeigende Widerstandsmefsapparat kann vereinfacht und verbessert werden, wenn man demselben die folgende Anordnung giebt.The direct pointing resistance meter protected by Patent No. 75503 can be simplified and be improved by giving it the following arrangement.

Ein nicht homogenes Magnetfeld ist dadurch hergestellt, dafs gemäfs Fig. 1 ein kräftiger Hufeisenmagnet mit zwei Polschuhen armirt wird, die einen nach einer Seite hin allmälig zunehmenden Luftzwischenraum zwischen sich lassen und von oben gesehen (Fig. 2) kreisförmige Gestalt haben. In dem so hergestellten, sich nach einer Seite hin erweiternden Interferricum können sich zwei niedrige Drahtspulen S1 S2, die mit einer Achse α fest verbunden sind, leicht drehen. Die Kraftlinien, welche diese Spulen beim Stromdurchgang liefern, laufen parallel denen des inhomogenen festen Magnetfeldes. Die Schaltung ist nach dem im Haupt-Patent angegebenen Schema getroffen und so vorgenommen, dafs sich beide Spulen von der Stelle gröfster Felddichte fortzubewegen trachten. Unterliegt also das bewegliche System keinen weiteren Richtkräften wie den von der Wechselwirkung des festen mit den beweglichen Feldern herrührenden, so ist auch die Gleichgewichtsbedingung die nämliche, wie im Haupt-Patent ausgeführt, und also die Einstellung des Systems nur durch die in beide Stromzweige eingeschalteten Widerstände bedingt.An inhomogeneous magnetic field is produced by armoring a powerful horseshoe magnet with two pole pieces according to FIG. In the interferricum produced in this way and widening towards one side, two low wire coils S 1 S 2 , which are firmly connected to an axis α , can rotate easily. The lines of force that these coils deliver when the current passes through them run parallel to those of the inhomogeneous fixed magnetic field. The circuit is made according to the scheme given in the main patent and made in such a way that both coils tend to move away from the point of greatest field density. If the moving system is not subject to any further directional forces such as those resulting from the interaction of the fixed and moving fields, then the equilibrium condition is the same as stated in the main patent, and the setting of the system is only due to the resistances connected in both branches of the current conditional.
