"Date and number of convention priority 1917-01-19" ; this may be a reference to either a German or an Austrian parent patent. Siemens & Halske, as such, yield extensive Spanish results on Espacenet, oddly. The priority patent mentioned above may have been filed under another Siemens corporate designation. This Siemens & Halske A.-G., based in Berlin-Siemensstadt and Vienna is to be somewhat disambiguated from Siemens és Halske Részvénytársaság, based in Budapest, found in Patent HU-1900-21140.
The “A.-G.” in this “Siemens & Halske A.-G.” is of the “Aktiengesellshaft” variety, as shown on the original document of this patent. See company types.

- “Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én (or án)”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know which legally constitutes the patent’s being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.
