Really nice to see this instant film production line at work, also the comparison with some of the Kodak equipment and the photos in Robert Shanebrook's book "Making Kodak film" (http://www.makingkodakfilm.com/), as you can clearly see some superficial similarities in the coating operations at work.

Added the video to the APUG video section:

Why do the examples of PX look so crap?

You would have to ask someone at TIP that question!

Thanks Marco. I should have thought of that.

Thanks Marco. I should have thought of that.

The APUG Video section seems to be a bit a "forgotten" section on APUG. Strange, since I remember Sean setting it up upon request by APUG members... For some inexplicable reason, even though I was never one of those requesting it, I became top contributor, with only a handful of others posting links. :confused:

I would have expected much more participation. Anyway, the number of views on the videos is quite good, although not sky rocketing like on YouTube where the originals are.

Maybe people think they need to upload the videos to APUG, which isn't the case, it is just a bunch of links to videos elsewhere. Really easy to add a link to an existing video elsewhere, just copy the browser HTTP adress.

Very interesting. Thanks, Ron and Marco.

Looking at this video carefully, I realize that the Kodak version of the slide hopper is subtly different than the one shown. I guess that is to be expected.

...the Kodak version of the slide hopper is subtly different than the one shown.

Just curious, did/does Kodak own patents on the slide hopper?

Yes they did. I don't have the patent # here, but I've posted it here someplace. The inventor was Russell. I have some diagrams and the patent reference in my book.

I don't believe that the curtain coater was patented or disclosed. I think it was a manufacturing secret. At least I never saw a patent on it, nor was I allowed to see one in operation. My work only used it one time IIRC. Of course, I used the slide coater quite frequently, sometimes every other week.

Hah. after I put this up, I remembered that one example in a patent of mine used the curtain coater and probably referenced a patent if there was one. I'll have to look that up!
