Patent DE-1910-04-04 August Wendtland

This patent has many descendants but appears not to have been granted in Germany. Repeated searches of espacenet and DPMA do not find it. In the text of the French version, much of the emphasis is on compressed air being directed under the wings. Propulsion seems to be the main subject of the Danish one. So it may be that these patents are not actually a family; it's a best guess for right now.
