- Aaron Cobet helped translate: It's for air not water. It's a basic structure onto which other things are to be attached. It's made of celluloid, which is very light and elastic and can withstand wind pressure. It has four blades, which seem to be flat but then apparently change form in the air. (that last bit is not stated but he infers it)
- might be the shortest patent text ever example
- There is a Berghaus with a bunch of publications in Zeitschr. Luftschr. Maybe the same person as this inventor.
- Inventor location: Essen Ruhr-West (presumably same as the modern city of Essen)
