Patent US-1913-1147294

- Tech class CPC B64C23/005: Influencing air-flow over aircraft surfaces
- Inventor location: Beurrier is filing from Beurrier Thaims, near Cozes, département Charente-Inférieure, France, and Bigourdan is filing from Maisse, département Seine-et-Oise, France
- Witnesses of the inventor signatures are different; Bigourdan seems to have been in France, whereas Beurrier perhaps not based on the names of his witnesses.
- Bigourdan's name is confusing. It's usually Edouard Jean, but here it's Jean Edouard, and on other patents it says Edmond.
This patent is not explicitly a patent of addition, or supplemental patent, but it's got the title and diagrams of a French ancestor.
