Conventional explanations for observations of anomalous behaviour of mechanical systems during solar eclipses are critically reviewed. These observations include the work of Allais with paraconical pendula, those of Saxl and Allen with a torsion pendulum and measurements with gravimeters. Attempts of replications of these experiments and recent gravimeter results are discussed and unpublished data by Latham and by Saxl et al. is presented. Some of the data are summarized and re-analyzed… Expand

Observations of Correlated Behavior of Two Light Torsion Balances and a Paraconical Pendulum in Separate Locations during the Solar Eclipse of January 26th, 2009
On January 26th, 2009, simultaneous observations of the reactions of two very light torsion balances (Kiev, Ukraine) and a paraconical pendulum (Suceava, Romania, 440 km away) were performed during aExpand
Solar Eclipses and the Surface Properties of Water
During four solar eclipse events (two annular, one total and one partial) a correlation was observed between a change in water surface tension and the magnitude of the optical coverage. During oneExpand
Link between Allais Effect and General Relativity’s Residual Arc during Solar Eclipse
The purpose of this article is to establish a relation between two gravitational anomalies, one that has attracted part of the scientific community, the Allais effect that occurs during solarExpand
Precise Underground Observations of the Partial Solar Eclipse of 1 June 2011 Using a Foucault Pendulum and a Very Light Torsion Balance
Simultaneous observations of the solar eclipse on 06/01/2011 were carried out using a Foucault pendulum and a torsion balance. The instruments were installed in a salt mine, where the interferenceExpand
The Allais Effect and an Unsuspected Law of Gravity
Anomalies in measurements made with pendulums and torsion balances have led to a suggestion of the reconsideration of the laws of gravitation. This paper discusses the anomalies and postulates thatExpand
The Shielding of Gravitation: An Old Unresolved Puzzle
In the memory of Marussi and its memorable pendulums, made for the observations of Earth tides but used for the unexpected observations of the free modes of the Earth and the also unplanned attemptExpand
An Experimental Gravimetric Result for the Revival of Corpuscular Theory
Abstract Gravity measurements made in the Montreal area during the solar eclipse of 10 May 1994 show a weakening in the soli-lunar attraction at the time of the occulta-tion. This gravitationalExpand
Gravitational Weakening of Seismic Origin as a Driving Mechanism of Some Astronomical Anomalies
The anomalous increase of the astronomical unit, the mysterious secular increase of the lunar eccentricity and the flyby anomaly are important issues of modern astronomy. This study aims to determineExpand
Solar Eclipse Anomalies and Wave Refraction
There is some inconclusive evidence that measurement devices sensitive to local gravitation exhibit anomalous behaviour during solar eclipses. We investigate if these findings can be incorporatedExpand

Allais gravity and pendulum effects during solar eclipses explained
Gravitational and other anomalies seen repeatedly in connection with solar eclipses have led to speculation about a possible gravitational shielding effect as the cause. Here we show that an unusualExpand
New measurements with a torsion pendulum during the solar eclipse
During the solar eclipse of 11 July 1991 in Mexico the period of a torsion pendulum was measured in order to reexamine possible anomalies observed in previous experiments of this kind. In ourExpand
Interpretation of the tidal residuals during the 11 July 1991 total solar eclipse
Abstract. Observations of gravity and atmospheric pressure variations during the total solar eclipse of 11 July 1991 in Mexico City are presented. An LCR-G402 gravimeter equipped with a feedbackExpand
Anomalous gravity data during the 1997 total solar eclipse do not support the hypothesis of gravitational shielding
We present arguments that rule out the recent suggestion by Wang et al. that their observations of anomalous gravity data during the 1997 total solar eclipse in China could be evidence for shieldingExpand
Observation of 1990 solar eclipse by a torsion pendulum.
TLDR
During the solar eclipse of 22 July 1990 in the city of Bielomorsk of the U.S.R., the torsion pendulum experiment of Saxl and Allen was repeated and the relative change in the pendulum's period associated with the eclipse was found to be less than 5.2 times 10 sup minus 5 (90% confidence). Expand
Gravity Anomaly During the Mohe Total Solar Eclipse and New Constraint on Gravitational Shielding Parameter
By using a high-precision LaCoste-Romberg gravimeter, continuous and precise measurements were carried out during the March 9, 1997 total solar eclipse in Mohe region in Northeast China. The gravityExpand
Did the solar eclipse of August 11, 1999, show a geomagnetic effect?
The solar eclipse of August 11, 1999, presented good conditions for the study of associated geophysical effects. Ionospheric measurements clearly show a decrease of electron density due to theExpand

The present article is the concluding article in a series discussing the results of the author's experiments with paraconic pendulums during solar eclipses from 1990 to 1994. During an eclipse, it isExpand
Possible evidence from laboratory measurements for a latitude and longitude dependence of G
Stability arguments suggest that the Kaluza-Klein (KK) internal scalar field, $\Phi$, should be coupled to some external fields. An external bulk real scalar field, $\psi$, minimally coupled toExpand
An Experiment Concerning Gravitational Shielding
