 aber gegen den Meridian bedingen und demnach für die Zwecke eines Kompasses unschädlich bleiben. 



   Man könnte nun meinen, dass die Reibung bei Schwankungen des ganzen Apparates, also auch des Ringes   R   mit der Blattfeder B um die Richtung Z-Z, wie sie bei Schlinger- und Stampfbewegungen eines Schiffes auftreten, die Kreiselachse ebenfalls gegen die
Horizontale in Schwankungen versetzen könnte und dass diese Elevation ihrerseits zu Bewegungen aus dem Meridian heraus Veranlassung geben könnte. Dies wäre auch der
Fall, solange die   Schwingungsdauer   des Kreiselkompasses kleiner oder von derselben   Grossenanordnung   wie die des Schiffes ist. Indessen muss der Kreiselkompass schon aus anderen Gründen eine Schwingungsdauer von über einer Stunde haben, während die
Schwingungsdauer   der Schiffsbewegnng   nur 10 bis 15 Sekunden ist.

   Bei diesem Verhältnis von mehr als 200 zu 1 kann nach der Theorie der erzwungenen Schwingungen der schwankende Ring R selbst bei ziemlich starker Reibung den   Kreisel K nicht   in merkliche
Schwankungen versetzen, so dass die vermeintlich Störung bei der Langsamkeit der Kreisel- schwingungen nicht auftreten kann.

 but against the meridian and therefore remain harmless for the purposes of a compass.



   One could now think that the friction with fluctuations of the whole apparatus, i.e. also of the ring R with the leaf spring B around the direction Z-Z, as it occurs with rolling and pitching movements of a ship, also against the gyro axis
Horizontal could cause fluctuations and that this elevation could in turn give rise to movements out of the meridian. This would also be the
This is the case as long as the period of oscillation of the gyro compass is less than or of the same size as that of the ship. However, for other reasons, the gyrocompass must have an oscillation period of over an hour, while the
The period of oscillation of the ship's movement is only 10 to 15 seconds.

   With this ratio of more than 200 to 1, according to the theory of forced vibrations, the fluctuating ring R cannot noticeably affect the top K even with fairly strong friction
Shift fluctuations so that the supposed disturbance cannot occur due to the slowness of the gyroscopic vibrations.

PATENT. ANSPRUCH ; Kreiselkompass mit kardanischer Aufhängung, dadurch gekennzeichnet, dass zur Er- zietung einer starken Dämpfung der Schwingungen Anordnungen derart getrolfef bind, daB die Elevationen einer erheblichen mechanischen Reibung entgegen stattfinden, während die Schwingungen aus dem Meridian heraus möglichst reibungslos bleiben. EMI2.4 PATENT. CLAIM ; Gyro compass with cardanic suspension, characterized in that, in order to achieve a strong damping of the vibrations, arrangements are trolfef in such a way that the elevations take place against considerable mechanical friction, while the Vibrations out of the meridian stay as smooth as possible.
