The addition 22826 of Marius Latour PURPORTS to be an addition some "506633", PURPORTED as being filed 1915-11-11. At This Patent FR-1919-506633 had the Espacenet data-entered title "Improvements in electromagnetic wave signalling systems" which was taken from the addition 22826 of Marius Latour. We have been in contact with Espacenet. Though the two patents are not related, the entered titles, even as translations, were not viable, in either case. This has been corrected, in both cases. The non-relation between Latour's purported addition to some 506633 and the only FR506633 we have found is still unexplained. Now, the IPC classifications have been removed. CPC H03B7/10, in the case of this patent, reflects the state of affairs before the corrections on the part Espacenet.
Regarding Espacenet, we are dealing with a huge database, and THEY are dealing with a huge database, addressed by workers of variable diligence, varying francophone capacity, and, likely, profound pressure in the interests of non-antique patent matters of contemporary(to us) proprietary import.
This Patent FR-1919-506633 shows "Système rationnel de stabilisation et de manœuvre de l’équilibre transversal des aéroplanes et de leurs évolutions horizontales".
This Patent FR-1919-506633, on Google Patents, gives a sprawl of information, including ITALIAN usage of the number 506633. This is an odd case, with definitely at least some digital data juggling errors in modern databases, and the possibility of antique data entry error or inconsistency of protocols.
