Both the Hungraian entered data and that displayed on the original document make reference to a priority date 1909-05-07. It is therefore offsping of Patent GB-1909-12556, to which its diagrams are identical well. It features among other things the propellers, or “vortex lifters” as Dring calls them in the initial British filing.

- “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.
