This is a case likely of Austrian publication of a French patent being delayed by wartime hostility. (The titular year date of the Austrian patent, within the Espacenet system, is based in this case on the year of publication.) After the fact, it is treated as an Austrian patent being valid, from 1916-07-15. Reference to Patent FR-1912-447782 is made via French priority date 1912-08-06, as shown on this patent's original document.
