Hello
So here, our anteriority study was based on the patents filed before those of St-Hilaire. Thanks to the website
http://ep.espacenet.com/advancedSearch?locale
Much information has been found on one of St-Hilaire's patents. mainly the number US6899075B2. Because when you file a patent, if there is an anticipation, it will appear on the patent ...
Strange thing (...) this patent in question is not really available anymore, it's a
for another which replaces it in which is cited bcp less anteriority.
But I have a screen copy of what to see:
look at "references cited" ...
Regarding the early days of the concept, someone told us that the first patent filed dates back to the end of the 19eme century, but that is in fact a solution that would not work in reality. But we had not found any information about it.
With regard to patents concerning a deformable rotor system, here is a chronology:
1963 Pierre Magnenet, a Frenchman (No. FR1376285A, to search
again here if you want it
1965 Andrew Novak (US3196854A1)
1967 - 1977 Alfred Jordan, German files various patents (in the disorder CH440832A5, DE1295569B1, DE1451764A1, DE1551118A1, FR2374512A1, US3295505A1, US3369529A1, US4181481A1)
1976 Martin Artajo Jose Ignacio a Spanish (CA999241A, also look at the other patents which he deposited, it is interesting and which reminds me of the one of St-Hilaire concerning the Quasiturbine with "trolleys")
In 1980, Jean-Pierre Ambert is applying for a patent application (FR2493397A1) which, it seems to me (tell me if I'm wrong?) Did not succeed because it has been presented previous anteriorities.
in 1986. , patent publication of an Italian, Contiero (WO8600370A1)
And then come from St-Hilaire,
