- “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 nearly 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 Hungarian form of the inventor's name is "Báró Pfeiffer Kálmán". We will treat this as "Baron Kálmán Pfeiffer", in keeping with our protocol of "semi-Westernization", that is, putting the given name before the family name, while keeping the Hungarian accent marks and spelling. This inventor was possibly a Hungarian living in Austria.
