Regarding Espacenet, this is an odd case of a British patent in which the simple patent number, not inclusive of any year, is searchable and workable between our protocols and those of Espacenet.

This patent was not accepted by the British office, for whatever reason.

Reference is made to a French predecessor, filed 1916-06-13, that is, to Patent FR-1916-493411.
