Here we have a “Krocker Rezső” of “Teplitz (CS)”. This is fairly definitely the Rudolf Krocker we have elsewhere working with LTA.
Patent DE-1899-123884 has the earliest filing date withing a patent family which is being put together here, and is therefore being treated as the parent patent.
“Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know the 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.

- Inventor location: “Teplitz (CS)” (This is an odd national designation coming from the Hungarian database in that it is neither per se contemporary, to us, nor nationally proper to the time. I think we are dealing with “Bohemia” here, and making use therefore of AH.)
