[visionlist] Robert Musil and the Color Wheel

[Macleod, Donald]

BTW the inventor of that interesting and useful contraption was the Austrian writer Robert Musil (who studied engineering first, then rejected academia to write important novels):

The inner workings of “Musil'scher Farbkreisel” are described in the catalog of Spindler &Hoyer, online at

Sandro,

Figures 7, 8, 12, and 13 show an episcotister, I believe.  It is a color wheel that allows you to change the proportion of 2 colors (say white and black) while the disk is spinning at high speed. Can’t touch German machines!

Hello,

Here some indications:
Figures 12-13 : Farbenkreisel zur beliebigen Verstellun der Sektore, während der Rotation (Couloured disc on which the size of the sectors may be varied during rotation) may be E. Zimmermann, I do not see details on the photos but it is an handvariator.
Figure 6 : Graphische chronometer nach Jaquet (Jaquet's graphic chronometer)
Figure 7 : Einfacher Farbvariator (simple colour motor variator)
Figures 4 and 5 : Tourenzähler (Speed indicator)
Figure 9 : Deprez signal type (but I am not sure)
The other instruments are unknown to me. But photos do not indicate details.
I have not in my possesion the Heinrich Diel catalogue. I think you can find informations into this old catalogue.
Best wishes,

Serge

Hello everyone!

At the faculty we are doing exhibition of old psychological apparatus for which we need to find out their names and functions. We found many of them, but some of them are still unknown to us. If someone has any information for any of them, I would be very grateful if you shared it with me.
