Description
Verfahren zur Bestimmung der Anziehung von massen, insbesondere der Erdanziehung. Zur Bestimmung der Anziehung von Massen und .insbesondere der senkrechten Komponente der Erdanziehung benutzt man bekanntlich vorwiegend Instrumente, welche auf der Messung der Pendelschwingungen beruhen. Diese Größen werden gemäß vorliegender Erfindung nach einem neuen. Verfahren bestimmt. Zur Messung dient ein Massensystem, das als .ganzes oder in seinen Teilern eine Lageänderung erfährt, wenn die Newtonschen Kräfte, unter deren Wirkung es steht, sich ändern. Die Lageändemng ein dem System soll nun dadurch kompensiert bzw. das System in seine frühere Lage dadurch zurückversetzt werden., daß die Dichte des Mediums, in dem das System sich: befindet, und damit der Auftrieb, welchen es als ganzes oder in seinen Teilen erfährt, durch geeignete Maßnahmen verändert wird. Die Größe dieser Dichteverschiebung wird am besten mit Hilfe eines Druckmessers ermittelt und dient als Grundlage der Berechnung der Änderung, welche die Anziehungskräfte erfahren haben. Es hat sich: gezeigt, daß auf diese Weise eine sehr genaue Bestimmung der Anziehungskräfte möglich ist.Procedure for determining the attraction of masses, especially the Gravity. To determine the attraction of masses and, in particular, the vertical As is well known, the components of gravity are mainly used for instruments, which based on the measurement of the pendulum oscillations. These sizes will be given in accordance with the present Invention after a new one. Procedure determined. A mass system is used for measurement, that undergoes a change of position as a whole or in its divisors, if the Newtonian Forces under whose action it is change. The situation change in the system should now be compensated or the system is set back to its previous position that the density of the medium in which the system is: is, and thus the buoyancy which it experiences as a whole or in its parts, by suitable ones Measures is changed. The magnitude of this density shift is best with Determined with the help of a pressure gauge and serves as the basis for calculating the change, who have experienced the gravitational pull. It has been shown: that on this Way a very precise determination of the attractive forces is possible.
In der Abbildung ist eine Ausführungsform des Verfahrens dargestellt. Zwischen den Böcken E ist ein sehr dünner Quarzfaden horizontal ausgespannt. In der Mitte des Fadens bei O ist senkrecht zu ihm das horizontale Quarzfädchen B angekittet, an dessen Ende sich die Kugel C befindet. Von demselben Punkte O geht ein sehr leichtes Quarzfädchen senkrecht nach unten und spielt als Zeiger auf der Skala F. Die ganze Vorrichtung ist in einem luftdichten Gehäuse eingeschlossen. Bei M ist ein Manometer angebracht, welches in bekannter Weise gestattet, sehr feine Unterschiede des Luftdrukkes zu messen..One embodiment of the method is shown in the figure. Between A very thin quartz thread is stretched horizontally on the bucks E. In the middle of the thread at O the horizontal quartz thread B is cemented perpendicular to it, at the end of which the ball C is located. From the same point O there is a very easy one Quartz thread straight down and plays as a pointer on the scale F. The whole Device is enclosed in an airtight housing. At M there is a pressure gauge attached, which in a known manner allows very fine differences in air pressure to eat..
Bei Benutzung der Vorrichtung wird in der folgenden Weise verfahren: Wird infolge einer Erhöhung der senkrechten Komponente der Erdanziehung die Kugel C um ein :geringes heruntergezogen, so wird so lange Luft in den Apparat hineingepumpt, bis der Zeiger D wieder auf den ursprünglichen Punkt der Skala F einspielt. Durch Berechnungen auf Grund dieser Messung der Druckänderung lassen sich Kräfteänderungen von ro-" C G S-Einheiten mit Sicherheit quantitativ nachweisen.The procedure for using the device is as follows: Becomes the sphere as a result of an increase in the vertical component of gravity C is pulled down a little, air is pumped into the apparatus for as long as until the pointer D moves back to the original point on the F scale. By Force changes can be calculated on the basis of this measurement of the pressure change of ro- "C G S units with certainty quantitatively.
An Stelle der beispielsweise beschriebenen Vorrichtung sind noch andere Ausführungsformen des Verfahrens möglich. So kann man die Erdanziehung anstatt auif einen Torsionsfaden auch auri eine feine Spirale, einen elastischen Quarzfaden oder irgendein anderes elastisches Gebilde .einwirken lassen. Die Änderungen der Kraft dieser Einwirkung können auch in diesem Falle mittels der Dichteänderung des Mediums kompensiert und dadurch bestimmt werden..Instead of the device described by way of example, there are still others Embodiments of the method are possible. So one can use the gravity instead of auif a torsion thread also auri a fine spiral, an elastic quartz thread or allow any other elastic structure to act. The changes in force this effect can also in this case by means of the change in density of the medium compensated and thereby determined ..
