Description

Geradführung für 1VIeßschreiber. Es sind Einrichtungen bekannt, die dazu dienen, die kreisförmige Bewegung des beweglichen Organs von Meßgeräten im eine geradlinige zu verwandeln, damit die Aufzeichnung mittels rechtwinkliger Koordinaten möglich ist. Diese Einrichtungen benutzen mechanische Hilfsmittel in Form von Lenkermechanismen oder zwangläufigen mechanischen Führungen. Gemeinsam ist allen der Nachteil, daß das bewegliche Organ die mechanische Arbeit leisten muß, die zur überwindung der Reibung an den Führungsstellen erforderlich ist. Das Meßwerk muß daher .kräftiger- ausgeführt werden, als es zur- Artteige oder zur Aufzeichnung der Vorgänge allein nötig wäre, damit Reibungsfehler vernifeden werden.Straight guide for 1VIeß recorder. There are facilities known that serve to control the circular movement of the movable organ of measuring instruments in the to transform a rectilinear one, thus recording by means of rectangular coordinates is possible. These devices use mechanical aids in the form of link mechanisms or compulsory mechanical guides. They all have the disadvantage that the movable organ must do the mechanical work necessary to overcome the Friction at the guide points is required. The measuring mechanism must therefore .vigorously carried out than it is for the nature or for the record the processes alone would be necessary so that friction errors are negated.

Es_" sind .ferner Zinlichtungen zur Erzengong -geradliniger : l#4@ördinaten bekannt, bei denen:..aäs....ggpier .über eine scharfe Kante geführti- rhrd@- oder- der messerschneideartig ausgebildete Zeiger durch einen scharfkantig geformten Fallbügel intermittierend an 'das Papier gedrückt wird. Die ersterwähnte Einrichtung zeigt den Nachteil aller Registriereinrichtungen, die mit einer Deformierung des Papiers arbeiten. Das Papier ist bekanntlich sehr stark den Einflüssen der Temperatur und Feuchtigkeit unterworfen, und die Bewegungseinrichtung gerät leicht in Unordnung, wenn sich das Papier nicht wenigstens in einer Richtung frei ausdehnen und die erwähnten Einflüsse ausgleichen kann. Dies ist aber bei den erwähnten Instrumenten nicht der Fall.. Im übrigen ist bei den bekannten Einrichtungen ein Fallbügel notwendig, der nicht unbedingt zuverlässig arbeitet und jedenfalls eine Verwicklung darstellt.Es_ "are, furthermore, pinnacles to the ore gong - more straightforward: l # 4 @ ördinaten known, where: .. aäs .... ggpier. guided over a sharp edge- rhrd @ - or- the knife-edged pointer through a sharp-edged drop bracket is pressed intermittently on the paper. The first mentioned device shows the disadvantage of all registration devices with a deformation of the paper work. The paper is known to be very strong the influences of temperature and Subject to moisture, and the movement equipment is easily disordered, if the paper does not expand freely in at least one direction and those mentioned Can compensate for influences. But this is not the case with the instruments mentioned Case .. In addition, a drop bracket is necessary in the known devices, the does not necessarily work reliably and is in any case an entanglement.

Beim Erfindungsgegenstand sind diese übelstände dadurch beseitigt, daß die Geradführung nicht durch mechanische Hilfsmittel, sondern durch einen Magneten oder Elektromagneten mit linearer Polfläche erreicht wird.In the subject of the invention, these deficiencies are eliminated by that the straight line is not by mechanical means, but by a magnet or electromagnet with a linear pole face is achieved.

In der Zeichnung ist der Grundgedanke der Erfindung dargestellt, und zwar zeigt: Abb. i ein mit ihr ausgerüstetes Meßinstrument in der Vorderansicht bei abgenommenem Papierstreifen, Abb. z im Schnitt, Abb. ? in der Draufsicht mit teilweisem Schnitt.In the drawing, the basic idea of the invention is shown, and although it shows: Fig. i a front view of a measuring instrument equipped with it with the paper strip removed, Fig. z in section, Fig.? in the top view with partial cut.

Es bedeutet a das bewegliche Organ des Meßwerkes, b den Zeiger, der an iseinem, Ende einen unten zugespitzten Stift aus magnetischem Material (Eisen) c trägt. Die Spitze dieses Stiftes schwingt dicht über der Schreib--Räche d, über die der Papierstreifen e in bekannter Weise geführt wird. Unterhalb der Schreibfläche befindet sich ein Elektromagnet oder Magnet,/ mit schmalem Polansatz g, der über die ganze Breite des Schreibtisches hinwegreicht. Bei Erregung dieses Elektromagneten wird der am Zeiger hängende Stift c aus seiner Ruhelage abgelenkt und stellt sich so ein, daß die Spitze bei Bewegung des Zeigers über dem Papier eine gerade Linie beschreibt. Die Art der Schreibeinrichtung selbst kann hierbei beliebig gewählt werden.It means a the movable organ of the measuring mechanism, b the pointer, the at one end there is a pointed pin made of magnetic material (iron) c wears. The tip of this pen swings just above the writing surface d, over which the paper strip e is guided in a known manner. Below the writing surface there is an electromagnet or magnet, / with a narrow pole attachment g, which is above extends the full width of the desk. When this electromagnet is excited the pin c hanging on the pointer is deflected from its rest position and turns so that the tip is in a straight line when you move the pointer over the paper describes. The type of writing device itself can be chosen as desired will.

Die Aufzeichnungen können so erfolgen, daß der Zeiger entweder in bekannter Weise von Zeit zu Zeit durch einen Fallbügel niedergedrückt wird, oder es kann hierzu der Elektromagnet selbst benutzt werden, indem er genügend kräftig durch Stromstöße erregt wird. Wie häufig diese Stromstöße einander folgen müssen, hängt von der gewünschten Art der Aufzeichnung ab. Bei der Registrierung langsam verlaufender Vorgänge genügt es, in Abständen von einigen Sekunden Stromstöße in den Elektromagneten zu geben. Es kann aber auch beispielsweise der Elektromagnet durch Wechselstrom gespeist werden, wodurch die Impulse außerordentlich schnell aufeinander folgen und eine fast ununterbrochene Kurve aufgezeichnet wird.The recordings can be made with the pointer either in is known to be depressed from time to time by a drop bracket, or the electromagnet itself can be used for this purpose by making it sufficiently powerful is excited by power surges. How often these electric surges have to follow one another, depends on the type of recording you want. Slow to register In the course of processes, it is sufficient to apply power surges at intervals of a few seconds to give the electromagnet. But it can also, for example, the electromagnet fed by alternating current, which makes the pulses extremely fast successive and an almost uninterrupted curve is recorded.
