Hello to all AND IN PARTICULAR TO JOACHIM,
I would like to complete the history I am writing about DISTLER (for the French CFE association) by (i) a little paragraph concerning the DISTLER Industrial Property and (2i) the showing of some 0 accessories, if they exist, as for example rail stations, traffic signals, tracks devices.
Point (i) :
The firm has filed and obtained between 1924 and 1963 numerous patents and utility models (Gebrauchmuster) amounting to about fifty titles. I am mostly looking for the official documents filed in connection with the three-phase asynchronous AC system used (in principle) in the 1950 years by DISTLER to supply the locomotives of the types 121, 0B0 and 2B2. Such documents would have to exist because DISTLER wrote himself, on the interior side of the box of trains : "DEUTSCHE PATENTE - GM - INTER(national) PAT(ent) PEND(ing)".
Problem : I have asked a lot of data still available to me (I am an old European Patent & Trademark Attorney), but, at the time being, I have found no document describing and covering the DISTLER three-phase brushless flat motor wherein the stator has three windings and the rotor is a simple iron core. It may arrive that the searched patent(s) was(were) filed in the name of an other inventor ? I have also not found the patent(s) protecting the evolution of the first flat motor consisting of a cylindrical motor containing a permanent magnet which is also cylindrical and central and an armature without iron ?
What do you think of this situation ? Do you know a more detailed description of the three-phase DISTLER motors ?
Point (2i) :
I thank you in advance for the photo you may have and for your permission to take them again in my history.
Continuing best regards,
Maurice
