The alarm bell shown in the photo of the back plate is not the correct bell. The clock is well made, and like the Sonora chime clocks, is an interesting adaptation of the 89 movement.Torsion Pendulum Timepieces Kundo Kieninger & Obergfell Model 54 400 day clock circa 1954. This clock is...

acting somewhat as a pendulum, when the beam is coming to rest. The object to be weighed is placed on one pan, and standard weights are added to the other until the balance of the beam is established again. The unknown weight can then be determined by adding up the standard weights in...
It shows also the extent of swing of the beam on one side or the other, acting somewhat as a pendulum, when the beam is coming to rest. The object to be weighed is placed on one pan, and standard weights are added to the other until the balance of the beam is established again. ...
Emile et al.109 used a torsion pendulum to demonstrate the transfer of OAM carried by an electromagnetic wave, which was generated by a pair of turnstile antennas, to a suspended copper ring in the microwave region. A negative torque (NOT) occurs due to AM conservation when the AM of the...

Many high-precision Eötvös-type experiments have been performed, from the pendulum experiments of Newton, Bessel, and Potter to the classic torsion-balance measurements of Eötvös [100], Dicke [94], Braginsky [43], and their collaborators. In the modern torsion-balance experiments, two ...

As stated above, the validity of this assertion was first established by Galileo. The Hungarian R. von Eötvös, using a torsion balance, confirmed the principle of equivalence to an accuracy of 10”8. The American physicist R. Dicke and co-workers improved the accuracy to 10–10, and ...
