This French patent makes reference to the American priority date 1912-02-26.


Note on aeronautical linguistics: gives "aircraft refinements" and "Improvements to aircraft". Our data has actually shown "aéronef" used both in HTA and LTA contexts. This is an odd case. Patent GB-1913-4794, equal to this patent, actually uses "Airships", not so rare as equaling "aéronefs"; the vehicle is HTA, however, and English use of "Airship" in the context of HTA is rare.
