- Sáiz (1995), p.119, discusses this patent.
- Inference: We can extract both filing and grant dates from the info in espacenet's biblio page. The date at the top of the espacenet biblio page is the grant date. The date buried in the "priority number" is the filing date. This guess matches certain intuitions: Priority is a concept associated with filing date (at least, after 1883) and therefore espacenet is keeping that information in sorted order.)
18720116
- Originally solicited for 15 years, but expired due to incompletion and non-payment of fees. [Why a grant date listed here previously? Denial date?]
- Inventor location (all three): Huesca, Aragon, Spain
