No, I don't. But if you want it I will translate, my Russian is good
enough. And I have a Russian colleague temporary working with me.

Hi Marcin,
Thank you fo rthe Russian data, I had not seen the first page nor the
last page before.
Did you do any translation of those pages?

I use google plus several years of my primary education. I was taught
Russian in the school. Hardly remember anything now. I am attaching
pages I have (in Russian but with a poor OCR).
Thanks for the info on coupling. I will start playing with regular
dekatrons to get filling about it.
