Ancient German equivalent

Further to Andy Berks' response to Brian Rossman's query, the typical
priority claim back before 1962 or so, when the French first started
showing priority application numbers, DID cite the date, but not the
application number. In our shop circa 1960 a bright young lady with a high
school education compiled serviceable concordance data based on these dates
and the similarities between two abstracts, or an abstract and a chief
claim; when she couldn't handle an occasional item she'd ask one of the
professional info scientists.
But if I read the title of this German patent correctly it's a mechanical
medical device, some sort of blood sampler. If it were a chemical patent
there would be some reasonable hope; mechanical, forget it! Incidentally,
there are some (very) limited concordance data from this period available
in the old British CA, if you're lucky enough to still have your copy
(someone chucked ours without asking), and the old IDC concordance data
have some VERY useful info on organic chemistry going back into the '50s.
But not on mechanical devices.
