Patent HU-1910-62713

This inventor shows up fairly extensively on Espacenet, but largely in terms of smokeless gunpowder, and other things associated with explosives. We may find more on him. The aerodynamics featured within these diagrams are of great intrigue.

• “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.
