Description

Verfahren zur Verstärkung der Drehwaagenausschläge durch Resonanz. Bei der gleichförmig gedrehten Drehwaage wird das obere Ende des Torsionsdrahtes einer Gravitationswaage ununterbrochen gleichförmig gedreht und die Bewegung des Gehänges in bezug auf das Gehäuse beobachtet.Method for amplifying the swing balance deflections by means of resonance. In the uniformly rotated rotary balance, the upper end of the torsion wire becomes a gravitational balance continuously and uniformly rotated and the movement of the Hanger observed with respect to the housing.

Bereits Eötvös hat eine Anordnung angegeben, bei- welcher Gravitationsausschläge durch Resonanz verstärkt werden. Wulf hat insbesondere Gravitationsausschläge einer Drehwaage durch Resonanz für Demonstrationszwecke vergrößert. Bei beiden Anordnungen wird die ablenkende Masse im Rhythmus der Schwingungen des verwendeten Pendels umgelegt.Eötvös has already given an arrangement with which gravitational deflections be reinforced by resonance. In particular, Wulf has gravitational swings Rotary balance enlarged by resonance for demonstration purposes. With both arrangements the deflecting mass is shifted in the rhythm of the oscillations of the pendulum used.

Gegenüber diesen Verfahren wird in demjenigen nach der Erfindung die Schwingungszeit des Gehänges auf die Umdrehungszeit der gleichmäßig gedrehten Waage abgestimmt, das heißt es wird, da die Masse im Raume fest ist, die Stellung der Waage im Raume in bestimmtem Rhythmus geändert. Abstimmung ist dann erreicht, wenn auf die Drehungszeit von der maximalen Voreilung bis zur maximalen Nacheilung des Gehänges eine halbe, drei halbe, fünf halbe usw. Torsionsschwingungen des Gehänges kommen, denn dann addieren sich Gravitationswirkung und Torsionsschwingung, weil sie in gleicher Richtung wirken. Die Dämpfung der Torsionsschwingung muß naturgemäß so gestaltet werden, daß sie den Vorteil der Verstärkung durch Resonanz nicht vernichtet. Durch diesen Vorgang entsteht eine außerordentliche Vergrößerung des Gravitationsausschlages.Compared to this method is in the one according to the invention Oscillation time of the hanger based on the rotation time of the evenly rotated scale coordinated, that is, since the mass is fixed in space, the position of the The scales in the room changed in a certain rhythm. Voting is achieved when on the rotation time from the maximum lead to the maximum lag of the Hanger half, three half, five half, etc. Torsional oscillations of the hanger come, because then gravitational effect and torsional vibration add up, because they work in the same direction. The damping of the torsional vibration must be natural be designed so that they do not destroy the benefit of amplification by resonance. This process results in an extraordinary increase in the gravitational deflection.
