Russian IC info needed

[Neon_WA]

I just purchased these 1970s Russian ICs 2IR302B (2ИР302Б)

I purchased them due to their unusual package design.
The only reference I could find prior to end of auction was in a 1977 Russian paper on measuring containment liquids in nuclear reactors

here is an excerpt from page 9 (poorly translated)

Quote:

Transfer time from - stavlyaet10 not. Shift register is made ​​of single-ended scheme for chips 2IR302B

The person that provide the best further info will get one free for their time
