Description

Einrichtung zur Erzeugung von Thermo-Induktionsströmen. Die Erfindung bezieht sich auf eine Einrichtung zur Erzeugung von Thermo-Induktionsströmen nach Patent 384398 und betrifft die Ausgestaltung des Schirmes, durch dessen abwechselnde Erwärmung und Abkühlung die Magnetfelddichte zwischen den Polen von Induktionsmaschinen geändert wird. In der Hauptpatentschrift besteht der Schirm aus einer vollen Blechplatte, deren magnetische Durchlässigkeit durch Wärmewirkung geändert wird. Da :es zur Erzielung von Induktionswirkungen erforderlich ist, überhaupt nur die Magnetfelddichte zwischen den Polen der induzierenden und der-induzierten Magneten zu ändern, so genügt als Schirm auch ein perforiertes Blech oder ein Drahtnetz oder Drahtgitter zur Bildung des magnetischen Nebenschlusses bei dem induzierenden Magneten. Die magnetischen Kraftlinien drängen sich dann an den Stellen größerer magnetischer Leitfähigkeit zusammen und bilden einen nahezu vollkommen magnetischen Schluß. Wird der perforierte Schirm, das Drahtnetz oder Drahtgitter erwärmt, so wird die magnetische Leitfähigkeit vermindert und die Kraftlinien verlaufen nach den Polen des induzierten Elektromagneten, um bei Abkühlung des Schirmes sofort wieder in diesem zu verlaufen. Vor einem vollen Schirm aber hat ein perforierter oder ein Drahtschirm bzw. ein Drahtgitter den Vorteil, den thermischen Einwirkungen rascher folgen zu können, so daß schon. mit einem geringen Wärmeaufwande die gewünschten Wirkungen zu erzielen sind.Device for generating thermal induction currents. The invention relates to a device for generating thermal induction currents according to Patent 384398 and relates to the design of the screen, through its alternating Heating and cooling the magnetic field density between the poles of induction machines will be changed. In the main patent specification, the screen consists of a full sheet metal plate, whose magnetic permeability is changed by the action of heat. There: it to achieve of induction effects is required, only the magnetic field density between To change the poles of the inducing and the -induced magnets is sufficient as Screen also a perforated sheet metal or a wire mesh or wire mesh for formation of the magnetic shunt in the inducing magnet. The magnetic Lines of force then crowd at the points of greater magnetic conductivity together and form an almost completely magnetic circuit. Will the perforated Shield, the wire mesh or wire mesh heats up, so becomes the magnetic conductivity diminished and the lines of force run to the poles of the induced electromagnet, in order to run again immediately when the screen cools down. Before a full However, a perforated screen or a wire screen or a wire mesh has the advantage of to be able to follow the thermal effects more quickly, so that already. with a minor Expenditure of heat to achieve the desired effects.

Ausführungsbeispiele sind in den Abbildungen angedeutet.Exemplary embodiments are indicated in the figures.

Abb. i zeigt in schematischer Darstellung die allgemeine Anordnung einer Einrichtung zur Erzeugung von Thermo-Induktionsströmen, und die Abb.2 und 3 erläutern Bauweisen des Schirmes.Fig. I shows the general arrangement in a schematic representation a device for generating thermal induction currents, and Fig.2 and 3 explain the construction of the screen.

In Abb. i sind I und II zwei Magnete. Vor jedem Magneten befindet sich ein Weicheisenschirm a und b, die die Kraftlinien jedes Magneten kurzschließen und in. denen Temperaturunterschiede in beliebiger Weise hervorgerufen werden.In Fig. I, I and II are two magnets. Located in front of each magnet a soft iron screen a and b, which short-circuit the lines of force of each magnet and in which temperature differences are caused in any way.

Nach Abb. 2 besteht der Weicheisenschirm aus einem durchlochten Blech, nach Abb.3 aus einem Drahtgewebe.According to Fig. 2, the soft iron screen consists of a perforated sheet metal, according to Fig.3 made of a wire mesh.
