This French patent makes no outright priority date reference, and-though its diagrams clearly though inexactly reflect association with both Patent DE-1907-240268, and with Patent DE-1907-240976, which is its addition within the German system. It is clear, in any case, that this French patent streams in the patent family ultimately traced to Patent DE-1907-240268.
