We have a filing date and author match with the Lilenthal museum entry; however the title is a bit different and we perhaps shouldn't rule out the possible existence of another patent filed by this author on the same day.

See also Havel, 1910, L'hélice commandée par deux moteurs and Publication B2p0620e08, 1910, Embrayage automatique du moteur auxiliaire sur les aéroplanes clearly relating to this technology.
