- “Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én (or án)”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know which legally constitutes the patent’s being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.
- the Szellemi Tulajdon Nemzeti Hivatala database in anglophone setting, choosing the Patent option, among the Advanced search on the left of the page, and using patent classification “V/h” as the keyword

- Inventor location: Berlin-Siemensstadt, Germany
(Note: The Hungarian entered data says "Rapülőgépfark", which is "Rap machine tail". I took the liberty of "Repülőgépfark", which is "Aircraft tail". Actually, upon further examination, the original itself says "Röpülőgépfark". The "Rapülőgép" is possibly a typographical error, though it is not rare. The "Repülőgép" versus "Röpülőgép" differential between Hungarian entered data and Hungarian displayed originals happen quite frequently indeed, and may reflect changes in usage relative to "flying machine" and "aircraft" and "airplane".)
