Zusatz zum Patent 241053 vom 20. Januar 1910.Addendum to patent 241053 from January 20 , 1910.
Patentiert im Deutschen Reiche vom 31. Mai 1911 ab. Längste Dauer: 19. Januar 1925.Patented in the German Empire on May 31, 1911. Longest duration: January 19, 1925.
Die im nachstehenden beschriebene Einrichtung stellt eine weitere Möglichkeit dar, bei dem bekannten Fernzeigersystem mit mehrphasig gewickelten und untereinander durch Fernleitungen verbundenen, von Wechselstrom erregten Gebern und Empfängern nach Patent 241053 eindeutige Angaben zu erreichen. Bei dem dort beschriebenen Übertragungssystem handelt es sich darum, den einzelnen Übertragungsspannungen eine gleichgerichtete, von der Geberstellung unabhängige Zusatzspannung im positiven oder negativen Sinn überzulagern, so daß ein' Vorzeichenwechsel der Einzelspannungen nicht mehr eintritt, und so der dem Einfluß des resultierenden Wechselfeldes ausgesetzte, bewegliche Einstellkörper nur ein Feldminimum vorfindet.The setup described below is another option for the well-known remote pointer system with multi-phase wound and through each other Transmitters and receivers connected to long-distance lines, excited by alternating current, according to patent 241053 to achieve clear information. With the transmission system described there it is a matter of providing the individual transmission voltages with a rectified, Additional voltage independent of the encoder position in a positive or negative sense superimposed so that a change in sign of the individual voltages no longer occurs, and so the movable adjusting body exposed to the influence of the resulting alternating field only finds a field minimum.
Es ist nun nicht erforderlich, sich zur Herstellung eines solchen Stromsystems der bisher bekanriten Geberformen zu bedienen, bei denen in einem bewickelten Eisenring die Übertragungsspannungen durch einen drehbaren, mit Wechselstrom erregten Magneten erzeugt werden; es gelingt dies vielmehr auch mittels anderer Geberformen, die für manche Zwecke große Vorzüge haben dürften.It is now not necessary to establish such a power system as previously bekanriten encoder forms to use, in which the transmission voltages in a wound iron ring generated by a rotatable, alternating current excited magnet; rather, this also works by means of other forms of donor, which should have great advantages for some purposes.
Bei der neuen Einrichtung sind nur zwei Ubertragungsleitungen erforderlich, vorausgesetzt, daß auch an der Empfängerstelle das Wechselstromnetz vorhanden ist. Der Geber besteht aus drei unterteilten Drosselspulen, deren Teilpunkte je zu einem der drei dazugehörigen Kontaktkreise geführt sind. Diese Kontaktkreise sind in der aus der Figur ersichtlichen Weise mittels ihrer Stromabmehmer in Reihe geschaltet. Der Anfangspunkt des ersten Kontaktkreises und der Stromabnehmer des dritten Kontaktkreises sind mit dem Netz verbunden. Von den Stromabnehmern des ersten und zweiten Kontaktkreises gehen zwei Ubertragungsleitungen ab. Die drei Stromabnehmer sind isoliert miteinander gekuppelt.With the new facility, only two transmission lines are required, provided that that the AC power supply is also available at the receiving point. The encoder consists of three subdivided choke coils, whose sub-points are each led to one of the three associated contact circles. These Contact circles are in the manner shown in the figure by means of their current collectors connected in series. The starting point of the first contact circuit and the pantograph of the third contact circuit are connected to the network. From the pantographs of the first and second contact circle go from two transmission lines. The three pantographs are coupled to one another in isolation.
Der Empfänger besteht z. B, aus einem Eisenring mit fortlaufender Ringwicklung, die an einer Stelle aufgeschnitten und hier mit dem Netz verbunden ist. Zwei um je 120° von dieser Stelle verschobene Punkte der Wicklung sind mit den Ubertragungsleitungen verbunden.The recipient consists e.g. B, from an iron ring with continuous ring winding, the cut open at one point and connected to the network here. Two at 120 ° each Points of the winding that are shifted from this point are connected to the transmission lines tied together.
Die Figur zeigt ohne weiteres, daß bei der skizzierten Stellung des Gebers im Empfänger auf der Seite α ein Feldminimum besteht, und es ist leicht einzusehen, daß bei einer Drehung der Kontaktarme des Gebers ein Wandern des Feldminimums im Empfänger eintritt.The figure clearly shows that in the sketched position of the transmitter in the receiver there is a field minimum on the α side, and it is easy to see that when the contact arms of the transmitter are rotated, the field minimum moves in the receiver.
