(This is a fifteen year patent. Within the "Montant des droits" field of the catalogue in which this patent was found, this is designated as "634.92", a quite prevalent and purely legal designation not exclusive to aero material. This is an invention, per se, as opposed to the Belgian "perfectionnement" or the "importation".)
