The original title given here has been inferred from the francophone original of Patent FR-1911-438545, which is also the patent making specific reference to this Belgian filing date. The English title has been corroborated by the titles given in Patent HU-1911-64331 and Patent AT-1912-58647 as well as by the content and diagrams included within all the patents included within this family.
Belgian patent classification is a matter of extreme likelihood.

- Inventor location: Patent GB-1911-29319 has him located at 1, rue, de Metz, Perreux, Seine, France. Patent FR-1911-438545 locates him merely within the Seine “département”, a designation frequently used within our historic data, though now extinct, often signifying Paris. We have found a present-day Perreux, far from Paris. This is not crucial. The other patents within this family locate him in Paris. Patent GB-1911-29319 has him self-identifying as an engineer.
