[ARC5] System ID for 1939 patent

[Brooke Clarke]

Hi

Is there a system name for this RDF?

This patent shows a Radio Direction Finder installed in what appears to be a two seat biplane.  The patent application 
was in 1933 and it was granted in 1939.
The patent seems to cover all the parts of the system, not just one aspect.  There is no company assigned.
The inventor, Geoffery G. Kruesi, has other similar patents some for Bendix and Federal Signal.
Page one of the patent is here:

and clicking the image gives a larger image.  I'll try and attach the image below:

axioms:
1. The extent to which you can fix or improve something will be limited by how well you understand how it works.
2. Everybody, with no exceptions, holds false beliefs.
