Patent FR-1908-395756

Describes three main elements:
1. A joint différential for the symmetrical attachment of aeroplanes, allowing them some free movement in opposite directions in response to the air, with the goal of stability.
2. Propeller whose angle can be adjusted along the vertical axis.
3. Repliage ("refolding") of the wings, meaning some kind of adjustment of their alignment alongside the body of the airplane.
Refers to Patent FR-1907-375606, which deals with airplane framework.
(Patent GB-1909-7209 derives from this one, and covers the symmetrical wing mounting but not the propeller or the repilage. It receives a more general CPC/IPC classification.)
