Cf. Patent GB-1909-20886 and Patent FR-1909-410545. Austria, like Great Britain and unlike France, classified this patent under aeronautics. Following the national office, again, the IPC has this patent classified under aeronautics, though in a different subcategory. As von Mach had three related British filings, but (based on what we have found so far) just this one in Austria, there may be some conceptual overlap and imperfection of one-to-one mapping in the overall family.
Nine years elapsed between submission and granting.
The title may be helpful in finding the German originals which we know were filed (though not necessarily granted).
