Verfahren zur Herstellung magnetisierbarer Materialien von gleichzeitiger iqeringer elektrischer Leitfähigkeit für elektrische und magnetische Apparate?" \Process for the production of magnetizable materials by simultaneous iqeringer electrical conductivity for electrical and magnetic apparatus? "\

Zusatz zum Patente 226347 vom 7. Januar 1909.Addendum to patent 226347 of January 7, 1909.

Patentiert im Deutschen Reiche vom 12. Mai 1909 ab. Längste Dauer: 6.Januar 1924.Patented in the German Empire on May 12, 1909. Longest duration: January 6, 1924.

Es hat sich gezeigt, daß die Permeabilität der nach dem Patent 226347 hergestellten Stücke sich noch erhöhen läßt, wenn man den gepulverten Ferriten vor der Pressung noch feinst gepulvertes Eisen oder Ferrum reductum zusetzt. Die Menge desselben kann bis 90 Prozent des Gesamtgewichts betragen. Durch das Oxyd wird hier die Stromleitung vollständig unterbrochen, während der magnetische Schluß aufrecht erhalten bleibt.It has been found that the permeability of those prepared in accordance with patent 226347 Pieces can be increased if you remove the powdered ferrites before pressing finely powdered iron or Ferrum reductum is added. The amount of the same can up to 90 percent of the total weight. The power line is created here through the oxide completely interrupted while the magnetic circuit is maintained.
