Patentiert im Deutschen Reiche vom 4. September 1907 ab.Patented in the German Empire on September 4, 1907.

Schickt man durch einen Leiter einen elek-. trischen Strom, so erwärmt sich dieser Leiter. Die Temperatur, welche er dabei annimmt, hängt ab von der Stromstärke, von dem Verhältnis zwischen Oberfläche und Querschnitt des Leiters und von der Umgebung. Hüllt man den Leiter ein, so wird seine Temperatur im allgemeinen höher sein, als wenn er frei ausstrahlen kann. Es genügt auch schon, denIf you send an elec- tric. tric current, this conductor heats up. The temperature it assumes depends on the strength of the current and the ratio between the surface and cross-section of the conductor and the environment. One wraps If the conductor enters, its temperature will generally be higher than if it were radiating freely can. It is enough that

B. über den Leiter eine Glimmerscheibe, so wird hierdurch schon eine bedeutende Temperatursteigerung erzielt.ίο partially hindering the ladder's appearance, to achieve a temperature change of the same. If you hold z. B. on the head of a mica washer, this is how a significant increase in temperature has already been achieved.

In der vorliegenden Erfindung wird diese Erscheinung dazu benutzt, sehr feine Bewegungen, die nur durch geringe Energie hervorgebracht werden, auf beliebige Entfernung zu übertragen.In the present invention, this phenomenon is used to make very fine movements, which can only be produced by a small amount of energy, to any distance transfer.

Die Drehachse des Systems, dessen Bewegung übertragen werden soll, wird zu diesem Zweck mit einer dünnen Glimmerscheibe G verbunden (s. Figur), die die Bewegung mitmacht. Diese Glimmerscheibe schwebt über einem durch Strom erwärmten Leiter a, b und erhält passende Ausschnitte A1A1, die so gestaltet sind, daß bei der Drehung der Scheibe der Draht a, b nach und nach freigelegt wird, so daß seine Ausstrahlung nach oben nicht mehr behindert ist. Hierdurch ändert sich die Temperatur des Drahtes und damit auch sein elektrischer Widerstand, welche Widerstandsänderung in bekannter Weise auf ein Galvanometer übertragen wird.For this purpose, the axis of rotation of the system, the movement of which is to be transmitted, is connected to a thin mica disk G (see figure), which follows the movement. This mica disk hovers over a conductor a, b heated by current and receives matching cutouts A 1 A 1 , which are designed so that as the disk is rotated, the wire a, b is gradually exposed so that it does not radiate upwards is more disabled. This changes the temperature of the wire and thus also its electrical resistance, which change in resistance is transmitted in a known manner to a galvanometer.

Anwendungen dieses Verfahrens bieten sich bei dem Problem der Kompaßübertragung, ferner bei solchen Bewegungen, die Kontakte hervorbringen sollen, wo aber entweder die Energie der Bewegung so gering ist, daß direkt eine Kontaktvorrichtung nicht in Bewegung gesetzt werden kann, oder die Bewegung durch die Kontaktgebung nicht beeinflußt werden soll. ' .This method can be used for the problem of compass transmission, also in those movements that are supposed to produce contacts, but where either the Energy of movement is so low that directly a contact device does not move can be set, or the movement cannot be influenced by the contact target. '.

Auch wenn feine Bewegungen graphisch aufgezeichnet werden sollen, dürfte dieses Verfahren von Vorteil sein, denn die Energie des Übertragungssystems läßt sich durch passende Wahl des Leiterquerschnittes oder seiner Oberfläche und der im Leiter herrschenden Stromstärke beliebig steigern.This method should also be used if fine movements are to be recorded graphically be advantageous, because the energy of the transmission system can be reduced by suitable Choice of the conductor cross-section or its surface and the current strength in the conductor increase at will.

Auch in der drahtlosen Telegraphic, wo die Empfindlichkeit der bisherigen Relais meist nicht ausreicht, dürfte dieses Verfahren mit Vorteil verwendet werden können. Man kann nämlich zu diesem Zweck das Spiegelgalvanometer benutzen, um indirekt Kontakt herzustellen, wenn z. B. die oben erwähnte Glimmerscheibe einen Spalt erhält, der bei der geringsten Bewegung des drehbaren Systems in seiner ganzen Länge über den Metallfaden a, b tritt; dann wird durch diese geringe Bewegung eine große Widerstandsänderung erzielt, welche durch eine passend angebrachte Blasvorrichtung noch erhöht werden kann, und welche in bekannter Weise auf ein gewöhnliches Relais übertragen wird. Eine weitere Steigerung der Übertragungsenergie läßt sich dadurch erzielen, daß zwei Drähte verwendet werden, die nebeneinanderliegende Zweige einer Whe.atstonesehen Brücke bilden, und von denen der erste vor der Bewegung der Glimmerscheibe, derThis method can also be used to advantage in wireless telegraphics, where the sensitivity of the previous relays is mostly insufficient. You can use the mirror galvanometer for this purpose to make indirect contact when z. B. the above-mentioned mica disk receives a gap which occurs at the slightest movement of the rotatable system in its entire length over the metal thread a, b ; then a large change in resistance is achieved by this slight movement, which can be increased by a suitably attached blowing device and which is transmitted in a known manner to an ordinary relay. A further increase in the transmission energy can be achieved by using two wires which form adjacent branches of a Whe.atstonesehen bridge, the first of which before the movement of the mica disk, the
