"Date and number of convention priority 1916-04-18" ; this likely refers to one of Jakob Haw's several German propeller patent filings. At first glance, this priority date doesn't match up, but this will be sorted out. The priority date informantion is consistent from the original document and the entered data.
This is a near match relative to Patent DE-1916-332539, though the dates are off. The design specs are also close, but not identical. We are dealing with very precise matters of specialized design in the case of this inventor.

- “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.
