"Date and number of convention priority 1917-03-15" ; this is likely a reference to either a German or an Austrian parent patent. We are seeking clarification relative to the Budapest-based Siemens és Halske Részvénytársaság and relative to Siemens-Schuckert Werke GmbH. Espacenet results are broad and extensive, internationally and otherwise, with the chance of certain patent references going from one corporate designation to another, or possibly to an individual inventor who may or may not have other demonstrative connection to one of these corporate incarnations.

- “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.
- the Szellemi Tulajdon Nemzeti Hivatala database in anglophone setting, choosing the Patent option, among the Advanced search on the left of the page, and using patent classification “V/h” as the keyword
