And I can guarantee that Kodak does not use anything remotely resembling this equipment for making or coating.
It works, but is considered to be antique equimpent which is fully functional.
The post by Ian shows some modern equivalents of this type of equipment, which is still not in any way like Kodak methodology.
Excellent photos and description Jim! Thanks for posting these. Fascinating stuff!
That is very interesting about de-bubbling using ultrasonics. I guess this technique might also be used on a small scale. I have heard of a vacuum (low pressure) being used to de-bubble viscous liquids but not ultrasonics.
Kodak uses a mixture of filtration, vacuum and ultrasonics.
Each lab had a small ultrasonic setup to debubble coating melts prior to use.
