Patent FR-1903-335422

Apparently related to railways or ground structures, not to aero, but classified in B64C at some point.
- Tech class CPC F16K35/00: Means to prevent accidental or unauthorised actuation; CPC B64C11/343: Blade pitch-changing mechanisms mechanical automatic actuated by the centrifugal force or the aerodynamic drag acting on the blades
- Inventor location: Russie; Prilukskaya 2, St. Petersburg, Russia ; Engineer according to the analogous, GB patent
- These two are apparently the same invention, filed elsewhere: https://patents.google.com/patent/CH30104A and https://patents.google.com/patent/GB190318762A. The British one is lengthy, with 7 pages and 13 claims, and, skimming it, although it refers to atmospherics and air pressure, it doesn't refer to anything of aero craft.
- Unless a new reason appears, I'm marking it as NOT related to aircraft.
