Schaufelrad is the type of propulsion (" Lifting rotor ") , and Ernst Zenzem (or Zeuzem?) is the designer .
These pages are from Modern Mechanix 2/1931. The name of the craft is
Rotor Airship.

As for the name of the designer one can be relatively sure that it is Zeuzem, for in Popular Mechanics 1/1931 there is another spindle plane by Zeuzem, where the name is clearly visible on a model shown in the article (
Rotor-Zeusem). I assume that an editor might bungle up the name in copy, but the designer may be able to correctly spell his own name when he applies it to a drawing of his doing.

As for the names of these more exotic types of rotorcraft, here is an endless mix-up.
The types w/ cylindric barrel- or drum-like „wings“ are often labelled paddle-wheels, where in fact they are spindle planes or Walzenflügel (German for barrel- or drum-wing).
Paddle wheels (Paddel- or Schaufelrad) are those like – in the olden days – the Gray Goose (

https://helikopterhysteriezwo.blogspot.com/2017/06/choppers-helos-330-cyclogyro-modell-der.html).
Where the spindle planes (or drum-wings) work after the Magnus- or Coanda-effect, the paddle wheels operate after the principle of the Voith-Schneider-Rotor.
Adding to the confusion is the term cyclogyro, which basically both these types are labelled throughout. What I gathered from all these old magazine reads is that those early designers threw fancy words like helicoplane or cyclogyro or paddle-wheel at their contraptions, to name them, not to acurately describe a physical principle or a clearly defined type of craft.
Also I now realize that Jemiba has deconstructed most of this already further up this thread.
