There is more than 20 years that I study and research the gravity. For all these years I accomplished several experiences, in which it submitted magnets and/or electro-magnets in high rotations, to the most several interactions. In 1996 I became aware of the experience of Tampere in Finland, accomplished by Russian Ing. Podkletnov, that observed a gravitational anomaly provoked mysteriously above a superconductor disk in rotation. See the site: Podkletnov's basic article (1995) http://www.gravity-society.org/msu.htm This effect was never very understood, nor either there was some reasonable explanation for him. In the report of the experience (Conclusion), a vibration is described, an oscillation or a bad swinging of the disk, that didn't leave the disk naturally in the horizontal. It was here that I found a relationship among my experiences of the past. See the web page: http://www.geocities.com/rolfguthmann/Patent/patent.html I would like to have the friends' opinion, on this patent or perhaps until finding, through this road, some institution that can accomplish the patent-experience and consequently to prove my theory about the gravity.
