This and Patent FR-1902-320837 are clearly related, with the Hungarian diagrams being slightly more elaborate. Patent FR-1900-304673, on which we have limited data, may be a closer match to this earlier Hungarian filing. In any case, Kohn seems to have work on a series of patents, non-identical, though clearly quite closely related, with Patent FR-1900-304673 being the first filed, and being treated as the parent patent.

- “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: Pozsega (Hungarian Wikipedia links directly to Požega, Croatia, on English Wikipedia, with Požega, Serbia offered then as a further link.) It is likely that we are dealing with the Croatian possibility, with the city being located within the Kingdom of Croatia-Slavonia, and therefore well under Hungarian administrative suzerainty.
- Inventor occupation: “Privatier”, a well-heeled bourgeois, or at least “private person” (Magánzó), semantically patchy relative to any noble implications of Gentleman
