Servo operated mixing bottle, Rotated 180 degrees back and forth. This is one of four speeds.
The mixer is for tin plating solution, needing a lot of agitation, too much by hand.
The servo position is fed from a lookup table, sinusoidal. The servo distorts that somewhat but you may be able to detect the change.
Recorded with a Phillips Voice Tracer and then tidied and amplified in Audacity.
