Patent NL-1913-2447

We've uncovered an Espacenet error here. Our linking protocol works, as does that of the Netherlands Patent Office register, in this case, but the patent title, as entered on Espacenet, along with the IPC and CPC classification, belongs to another patent. The original document is proper to this patent.
Reference is made herein to a German patent filed 1912-11-04. Note here on the Dutch patent the lag between filing and granting dates. This is a case perhaps very neatly explicable by way of factors around World War I.
