Just to prove I've been working on your behalf, here is a shot of the entire pump setup with UF membrane. The red tubing with black plastic and stainelss fittings near my right hand is the high temperature, high pressure tubing for input at 60 PSI and 40 deg C. The red tubing in the background there is the failed experiment using a poly propylene tubing bridge which failed during the experiment.
You can see the plate and frame UF membrane in my left hand, and you see the entire pump setup in the middle of the picture.
This represents one frame in nearly 2 hours of taping for part #2 of the DVD which is devoted to advanced techniques.
It is taped in HDTV and hopefully will justify the work that went into it!
The UF filter looks like what I used to use for ion scrubbing our eluent in a ion chromatograph. It had sodium carbonate coming in one side and sulfuric acid in the other, and as the liquids went past each other, the H+ from the acid would cross over the membrane and the Na+ would come over and get flushed out with the acid solution as it left the membrane cartridge.
Well, DVD II took longer to edit than I thought due to the schedule of the videographer, and the difficulty of intercutting some of the scenes. In any event, when completed, we found an error in two titles so that they read incorrectly when run. So, Monday we have to re-edit the titles and then finally burn the disk.
As it stands now, DVD I consists of 4 parts with an introduction, making an Azo type emulsion and coating it, making an ISO 40 emulsion, and testing the coatings. The running time is about 1.5 hours and occupies about 4 G. DVD II consists of 2 parts including UF washing and pumped making. The latter part is so complex, I did not actually make an emulsion, I did everything in the light doing a "water run" as we often did at EK with complex makes so that we had a dress rehearsal so to speak. I wanted everything to be crystal clear and that required taping in the light. The running time of the second DVD is about 1 hour and occupies about 3G.
So, almost there. I thought you might like a summary and an update. I've included a photo from the pumped making segment in which I am using dual pump heads. It was the last segment to be completed.
Well, DVD 2 was finshed at about 11:30 last night. I burned a second copy today and backed up the files. Now, it is back to the book and the lab to upgrade formulas and take some detailed stills of some of the lab practices and setups described in the DVD.
It depends on the book more than anything else. Of course, workshop students can get along well with the DVD without the book, just by using class notes so I might consider a "special" for students. Look for an e-mail if that is workable.
Hi Ron,
would you have any problems with me purchasing a copy and using for educational purposes with the students at the Tertiary institution I work at. Would you need an extra payment to cover copyright? Please let me know if you have concerns about this and how we could iron them out.
Thanks in advance
Mike Wynd
