As usual, regarding Spanish material on Espacenet, we have noticed patterned errors of data entry. This patent shows "Priority date: 1922-03-29". Experience has taught us that this is likely the filing date, in Spain, not the the actual priority date.
Titular content suggest relation to Patent DE-1917-375592 or to Patent DE-1918-388537.
