Belgian perfectionnement RdBdI making reference to this patent

(The content fits quite well so as to designate this as Austrian 61611. We are currently fleshing out his other patents found via Espacenet, seeking among other things references to this Austrian parent patent. Being that we have found a very few typographical errors within RdBdI, relative to other data whether internal or external to the RdBdI, and given the wealth of virtually identical material filed by Sparmann in the other national offices, it seems overwhelmingly likely indeed that the RdBdI entry included here should refer to a patent filed in 5 September 1909.)

(Also, this patent, designated according to its year of granting, is the parent of a Belgian patent, dated according to the same criteria, at 1910. This has to do with a four-year delay between filing and granting, in the Austrian office, with Sparmann's reference made within the Belgian filing being based upon filing date. This patent seems also to be the unmentioned parent of at least one bloc within the other Sparmann patents we have on hand, all virtually identical and having to do with gyroscopically controlled stability.)
