I cant remember where I got them from, but I got 4 7" or 8" disks for about $25 a few years back..

Patrick at Oxycheq used to have some, but all sold out now.

Dear Dr mike
Do you know how the kit got water into it? Was it your error or the Boris? Kevin's membrane is like a plastic type of material. Is porex like that?

Just my two cents.
I know the membrane is very expensive but.... what where paying for is all the testing the kit went through to get the CE approval. Kevin is a sharp guy and a engineer. I would spend the money and buy his membrane. I think he tested a bunch of different membranes for WOB and effectiveness, but I don't now that for a fact.
Cheers Frankie

Thats what it was on the ut-240 (and what I used)
a big differance from £300.00 sterling

Joe the UT 240 project was over 10 years ago now a dim distant memory few will recall. Surely even allowing for inflation a more relevant example would be Peters Prism for best current use of a published test of a fitted membrane while keeping within WOB. Iain

Frankie: While we wait for a photograph. As for cost I understood the DTI North East Gateshead grant gave £77,000.00 ($135,000.00 USD) towards the cost of development and testing for the product.

As for the membrane I have doubts that it was fitted to the unit submitted for the CE test therefore the claims of WOB with it are misleading. I would further add that if a bunch of test have been done then a print out of a dry and wet test result should be obtained just to see the differences in WOBV.

but at least it wasn't a total failure... We still see remnants of that project even in current rebreathers, like the counterlungs on the PRISM

Its a shame there were so many problems with the elctronics, the basic envelope was quite well done...

By now someone should have posted a jpeg of this elusive membrane what's up? still developing the film? It had the makings of an interesting and helpful discussion.

Joe I really don’t want to get off topic here with the UT240 (moderator willing) as it has nothing to do with the post save the fact that the only possible link being that the electronics were contracted to the then pretty brilliant Ace Profile, Pro planner now ceased trading owed by Kevin Gurr.

As for the remnants in current rebreathers? its me that’s the remnant.

Re the counterlung comment and thanks to full QA traceable archive system with cheap camera included I enclose some of the early bag prototypes from the UT 240 days. In the words of the film industry any resemblance to characters living etc etc. Now back in the archive with it all, move along.

I for one still await the photos of the Boris membrane the test results and if it was ever submitted for the CE test approval with the membrane fitted.
However you have the right to remain silent and if you dont have a camera or dont appoint one then one will be provided for you. You have the right to remain silent but every thing you say will ...and may .. Iain Middlebrook.

Its always nice bringing back history when you can.. especially since the old eventually gets recycled as a neat new addition...
