Description

Anzeigevorrichtung für Stromumkehrung Das Patent 499 6o9 hat eine Anzeigevorrichtung für Stromumkehrung zum Gegenstand, bei welcher ein unter dem Einfluß eines permanenten Magneten stehendes bewegliches Eisenblechfähnchen von geringer Masse zur Anwendung gelangt. Das Eisenfähnchen ist entsprechend dem Hauptpatent an einem parallel zum stromführenden Kabel und unmittelbar an diesem liegenden permanenten Magneten drehbar gelagert und wird von einem um das Kabel liegenden U-förmig gebogenen Eisenblech angezogen oder abgestoßen. Es hat sich gezeigt, daß die Wirkung der Anordnung nicht beeinträchtigt wird, wenn das Eisenblech nicht vollständig U-förmig um das Kabel herumgeführt ist, sondern nur einen Teil der Länge des Kraftlinienfeldes ausfüllt. Es genügt auch ein gerades oder anders als U-förmig gebogenes Blechstück, das vom Felde des Kabels seine Polarität erhält.Current Reversal Indicator. Patent 499,6o9 has one Display device for current reversal to the object, in which a below the Influence of a permanent magnet, moving sheet iron flag from low mass is used. The iron flag corresponds to the main patent on a permanent one lying parallel to the current-carrying cable and directly on it The magnet is rotatably mounted and is bent into a U-shape by a device around the cable Iron sheet attracted or repelled. It has been shown that the effect of the arrangement will not be affected if the iron sheet is not completely U-shaped around the Cable is led around, but only fills part of the length of the force line field. It is also sufficient a straight or other than U-shaped bent piece of sheet metal from the Field of the cable receives its polarity.
