Indeed, Philips washers did this too, like my Philips H-axis toploader. Unfortunately you can't see it with that machine, but you sure can hear it.
What I love about the spin in the third video is the motor that works as an electric break after the spin has ended. I have never seen that on any other washer. I have a Braun juice-extractor that has this same system too, but never even thought about it could be used on a washer. I just love this feature, I watched that fragment over and over again!!
BTW, this is a washer that does real boil washes, 100*C, 212*F.
I think this is a bolt down machine that might not be bolted down very well, but I'm not sure about it. Most early Constructa's were bolt down machines, I remember that when the neighbours got a new Constructa and the old bolt down was removed they redid the floor of the mudroom where the washer was located.
This machine has indeed one cycle, with a timer on the left. On the other side of the machine is the dial for the temperature. These early machines didn't have a permanent press cycle or a delicate cycle. The machine in the videos is from around 1956.
Here's a picture of it.
