Patent BE-1914-219246.263844

This is a brevet of the "invention", variety, as these things were phrased within Belgian administrative culture. It has been found via its brevet of the "perfectionnement" variety, within the Belgian system, that is, Patent BE-1914-219246.263844. The two brevets belges apparently have analogous filings in France, and we are looking into this. There may be another "perfectionnement" within the Belgian side of this complex, being that the French parent brevet has two additions within the French system.


Note: This L.-M. Le Dantec is likely an individual who, with a few name variations, factors into various publications.
