Résumé, that is, summary, of this certificate of addition:
“The principle points of this addition consist in the extension of the use of half-masked wheels on the wings of airplanes or other surfaces displacing themselves in fluids, such that these wheels would be full or composed of elements, that they would be rigid or elastic, permeable or not, etc. in the interests of diminishing the resistance of surfaces in progression or in augmenting their mechanical effect.”
