This original makes reference to a likely German priority date 1916-04-29. In the case of German patents, the date given on the German original is typically one day after the actual filing date, as used internationally. In comportment with this, and in terms of content, we have a match with Patent DE-1916-332540, "Patentirt im Deutschen Reiche vom" 1916-04-30.

- “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.
