I just entered an abandoned air traffic control room, that have been abandoned since 1998 and I saw these stuff in it, Does you know what are they and the usage??
The first few pics It seems like a storage tank, like fuel tank The second pic looks like some engine, however it could well be some microwave magnetron or TWT tube parts of some assembly. The pics with text you can translate that on Google language tools, works very well (most of the time!) Then it is some video game Hope this properly answers your question Guru
I'd speculate that it was a backup power supply system with its fuel tank. The first picture is clearly a storage tank of some sort, with a simple contents indicator consisting of a float on the surface of the liquid, with an attached cord over a pulley dangling down to a weighted pointer in front of the scale to show how much was in the tank.
