Patent FR-1909-394427
(Interestingly, the device of stability and control is specifically applicable applicable within the marine field, submarine most particularly, as well as specifically to the fields of aviation and aeronautics. It nevertheless has the French "VI.4. Aérostation" designation, our FR 6.4.)
("Vasdényey", incidentally, is otherwise a Hungarian family name. This "Didier de Vasdényey" may or may not have some connection to Vasdényey Géza or Vasdényey Dezső of Patent HU-1901-28033. Here are the VASDÉNYEY inventor search results via Espacenet. Didier de Vasdényey and Victor de Vasdényey, as such, were productive in a few fields, some aero. The likelihood of a pair of brothers, filing jointly, like that in the case of the Hungarian patent above, with the timing taken into account, is suggestive perhaps of a Hungarian brotherly team moving to France. Patent FR-1903-329610 is of note, in terms of Didier de Vasdényey working in collaboration with Victor de Vasdényey.)
