Hi Christina,

Probably you already know this resource about photographic French patents before 1920 where you may do plenty of advanced researches :
    http://brevetsphotographiques.fr/index.htm


When you type caséine (not caseine) in it you may find several interesting results :
    http://brevetsphotographiques.fr/findexformulairematieres.asp?matiere=cas%E9ine

but there’s no track of a patent #  151.014...

And, as Kees wrote to you, 
http://www.camera-obscura.org/
is also a very valuable site : when you launch a research with  “caséine”, you get 11 published results

Bonne chance,
alternative cheers from France,
jean
