Re: Article Posted (RE: Sury & Misonne)
From the posted text: "The paper is sent out unsensit ized" This would mean that the paper was commercially available since the patent date, if not before. I would ask Judy when was edited the #18 in 1924, because the application date in Belgium was May 30th 1923, but the first published patent filed in Espacenet is the French one (granted September 13, published November 18). Curiously, the former French patent (FR460426 of 1913) was filed in Espacenet but not indicized (that is: without title, inventor name and date), and I have been able to find it only after having read the posted article. Philippe, perhaps you have the Belgian patent. May you tell us when it was granted? Alberto
