Gegenstand vorliegender Erfindung ist eine Einrichtung an Signalapparaten oder sogen, polarisirten Relais, welche die Wirksamkeit derselben erhöht und eine Rückwirkung auf den Signalstrom zur Folge hat, die als Rücksignal dienen kann.The subject of the present invention is a device on signaling devices or so-called, polarized relay, which increases its effectiveness and has a retroactive effect the signal stream, which can serve as a return signal.

Die Einrichtung ist auf der Zeichnung in Fig. ι schematisch dargestellt, während durch Fig. 2 bis 4 die Vorgänge innerhalb des Magneten und der Armatur veranschaulicht werden.The device is shown schematically in the drawing in Fig. Ι, while by FIGS. 2 to 4 illustrate the processes within the magnet and the armature.

Das Relais besteht aus einem permanenten Hufeisenmagneten A und den beiden seine Schenkel durchdringenden stabförmigen Armaturtheilen C und D aus weichem Eisen, welche in der Mitte zwischen den Schenkeln zusammenstofsen. Der eine dieser Armaturtheile C ist fest mit dem Magneten verbunden, während der andere D in der Richtung seiner Achse verschiebbar gelagert ist und durch eine Feder F in die punktirt gezeichnete Lage gebracht werden kann, in welcher er durch den Ansatz E* an einem von ihm getragenen Druck- und Signalknopf E gehalten wird, indem dieser Ansatz gegen einen Anschlag an dem das Ganze einschliefsenden Gehäuse B trifft.The relay consists of a permanent horseshoe magnet A and the two rod-shaped armature parts C and D made of soft iron which penetrate its legs and which come together in the middle between the legs. One of these armature parts C is firmly connected to the magnet, while the other D is mounted displaceably in the direction of its axis and can be brought into the dotted position by means of a spring F in which it is attached to one of it by the attachment E * carried push and signal button E is held by this approach against a stop on the housing B enclosing the whole.

Beide Armaturtheile, welche einen cylindrischen Steg zwischen den Magnetpolen bilden, werden von einer Drahtspule G umgeben, welche von dem Signalstrom so durchflossen wird, dafs derselbe die durch den permanenten Magneten A magnetisirten Armaturtheile C D entmagnetisirt, so dafs die Feder F zur Wirkung kommen und den Armaturtheil D in die punktirte Lage vorschnellen unr¹ hier unter Vermittelung von Contactfedern einen secundären Stromkreis schliefsen kann.Both armature parts, which form a cylindrical web between the magnetic poles, are surrounded by a wire coil G, through which the signal current flows in such a way that it demagnetizes the armature parts CD magnetized by the permanent magnet A , so that the spring F comes into effect and the Armature part D rushes into the dotted position and ¹ can close a secondary circuit here by means of contact springs.

Der besondere, von anderen Apparaten unterschiedliche Vorgang dabei ist folgender:The special process, different from other devices, is as follows:

Dadurch, dafs die beiden Armaturtheile aus weichem Eisen innerhalb der Drahtspule liegen, so dafs der bewegliche Theil auf seinem Wege diese nicht verläfst, ist es möglich, die Entfernung der Armaturtheile von einander gröfser und die Bewegung plötzlicher zu machen als bei anderen Apparaten. Durch diese plötzliche und schnelle Unterbrechung der magnetischen Kette und das plötzliche Herausziehen eines Theiles des weichen Eisenkerns aus der Drahtspule tritt eine starke Vergröfserung des magnetischen Widerstandes auf dem Wege durch die Drahtspule mit grofser Geschwindigkeit ein, was zur Folge hat, dafs der magnetische Strom, welcher der Differenz der magnetischen Kraft des Stahlmagneten und der Drahtspule entspricht, in einem ähnlichen Verhältnisse und in ähnlicher Weise abgeschwächt wird. Hierdurch wird in der Drahtspule ein kräftiger Inductionsstrom erzeugt, welcher einen Sprung des Signalstromes bewirkt, der an der Aufgabestation wahrgenommen werden kann und ein Zeichen dafür ist, dafs der Apparat functionirt hat.Because the two parts of the armature made of soft iron lie within the wire spool, so that the movable part does not pass this on its way, it is possible to increase the distance the fitting parts of each other larger and the movement more sudden than with other devices. Due to this sudden and rapid interruption of the magnetic Chain and the sudden withdrawal of part of the soft iron core from the wire spool a strong increase in magnetic resistance occurs along the way the wire coil with great speed, which has the consequence that the magnetic Current, which is the difference between the magnetic force of the steel magnet and the wire coil corresponds, is weakened in a similar ratio and in a similar manner. Through this a strong induction current is generated in the wire coil, which causes a jump of the signal current that can be perceived at the loading station and a The sign of this is that the apparatus has worked.

Aufserdem wird der Stahlmagnet durch den Umstand, dafs die Armatur die Schenkel des Magneten durchdringt und nicht wie bei bekannten Co.nstructionen an den äufseren Polenden liegt bezw. vorbeibewegt wird, infolge der Wirkung des Signalstromes nicht nur nicht geschwächt, sondern sogar verstärkt, und zwar in folgender Weise: Der magnetische Strom, welcher den permanenten Magneten durchfliefst, wird zwar durch den Signalstrom, welcher dieIn addition, the steel magnet is made by the fact that the armature is the legs of the Magnet penetrates and not at the outer pole ends, as is the case with known co-constructions lies resp. is moved past, due to the effect of the signal current not only not weakened, but even strengthened, in the following way: The magnetic current, which flows through the permanent magnet is caused by the signal current which the

Claims

Wire coil flowed through, in the middle part D of the magnet, d. H. in the part that lies between the armature parts, weakened resp. canceled by generating an oppositely directed magnetic current in this part by the signal current. In contrast, in the pole ends of the magnet, i. H. in the parts of the same which protrude beyond the armature, the magnetic current generated by the signal current is rectified; H. the magnetic force of the pole ends is increased. FIGS. 2 to 4 are intended to illustrate this. There is only magnet A with its armature, namely the fixed C and the movable one, penetrating the south pole of the magnet, without the wire coil. The arrows indicate the direction of the magnetic current BEZW. the position of the lines of force. Fig. 2 shows the apparatus before the signal current acts, so the arrows indicate the magnetic current which is generated by the magnet alone. The main part of the magnetic current moves through the part of the magnet located between the parts of the armature, which in the following is to be understood as A alone, and through the armature; a smaller part passes through the pole ends NS and the free space between them, like this the solid arrows are indicated. Fig. 3 shows the apparatus at the moment at which a current passes the coil, and the dotted arrows represent the magnetic current which is generated by the wire coil, that is, by the signal current. This current is directed in the opposite direction in the armature C D, and since it is now evenly distributed, one part goes through A of the magnet, another part through the pole ends N S and the free space between them. The former part of the current is directed in the opposite direction to permanent magnetism, while the latter has the same direction as it, i.e. H. the magnetism of the pole ends is amplified by the signal current. Finally, FIG. 4 illustrates the effect which the permanent magnetism of the pole ends exerts on the magnet after the signal current in the wire coil has ceased. The strong magnetism of the pole ends N S produces a magnetic current in the part A of the magnet which is in the same direction as the permanent magnetism. It is clear from this that the magnetism of the pole ends strengthens the magnetism of the magnet, which has been weakened by the signal current. If, therefore, the signal current is interrupted, the increased magnetism of the pole ends actually strengthens the magnet. The opposite of what happens in similar apparatus occurs, in that, with prolonged use, the one active part, namely the permanent magnet, does not become weaker, i.e. unusable, but more powerful, i.e. remains usable. Paτenτ claims:

1. Polarized callsign, which can also be used for relay purposes, of the type in which the effect of a powerful steel magnet on the valve, which is under the action of a spring, is canceled, when a current flows through a wire coil surrounding the latter, characterized in that, that the wire coil lies between the legs of the steel magnet and the armature that forms the core for it made of soft iron penetrating the legs of the magnet and in the middle between the magnetic legs, of which only one part is movable.

2. Device according to claim 1, characterized in that that the opening for the armature is so far back from the pole ends of the magnet that through the Effect of the current flowing through the wire spool strengthens the magnetism of the pole ends and thus a weakening of the whole magnet is prevented.
