I found a curious piece of glassware in an old medical lab that was 
being shut down, and which I was scrounching through for equipment.

It is essentially a U-tube, with one upright column, closed at the
top, with descending graduations of 0.01, 0.02, 0.03 'grammes'.
The other tube bulges out at the base to form a bell, with an open
lip about an inch across at the top.  The whole thing looks quite like
a little glass saxophone.

Nobody at all can tell me exactly what it is or how it was used,
although I suspect its use is something that would make second-graders
giggle insanely.  To whit, my employer, Dr. Dwight Miller, has pro-
nounced it "A piss-cup!"

Thank you, Dwight.

The only clue is the word "ureometer" etched on the upright column.
It still doesn't tell me what it measures, or how that measurement is
done.  Can anyone elaborate?

Our university maintains an MSDS (material safety data sheet) database which is
accessible (at least from our local network).  I assume other universities
do as well.  If you can somehow find your way to MERIT (or MICHNET) you
can access it as MSDS (with MSDS as the login name, I believe).

From here, I can simply 'telnet merit' though I don't know how far that
connectivity goes.

Yes, all the known solvents for PET are very nasty indeed:

phenol
o-chlorophenol
dichloroacetic acid
trifluoroacetic acid
hexafluoroisopropanol
pentafluorophenol
methylene chloride/hexafluoroisopropanol
tetrachloroethane/phenol 1:1
and various combinations of other chlorinated alkanes with halophenols

Not a single solvent that can be safely used in your kitchen!

I have a goal driven question.  I am interested in building a flexible  
sheet that naturally reverts to rigidity and yet can be rolled up to be  
put away.  My idea is that a weak matrix structure could be devised that  
quickly supported the current shape of the enclosing film.  The matrix  
would need to give way under sudden shock or firm strain and naturally  
reform.  I have talked with one chemist (quantum chemistry) who suggested  
a carbon & non-metal structure using primarily valence bonds and perhaps  
some scattered dipole bonds for greated strength.  She suggested that an  
organic chemist would be the best place to start looking.  I myself am not  
a chemist --- I am trying to see if this is possible or if someone has  
already devised such a matrix.  The actual application would be in  
building mobile computational devices.

E-mail responses would be fine, but I will monitor this news group for a  
while as well.  Thanks in advance.

decomposition products were and no one ever seems to say how they
found this out.  I would like a reference or even a hint about

Cna anyone tell me exactly what nickel activators do? I'm looking for a
nickel activator that is alkaline to use with cyanide gold in a brush plating
operation. Most nickel activators I've tested are acidic and that's a no no
around cyanide.

If anyone knows of a alkaline nickel activator or a good looking non cyanide
gold solution, I would much appreciate hearing about it. Cyanide makes me
 nervous. One potassium aurocyanide solution I sent away for has a ph of 4.7.
How can a cyanide be suspended in an acid ????

Hot melt adhesives (glue guns) normally work pretty well although they might 
prove difficult to use in your application.  Polyester is also used in 
photographic film so you might want to stop by your local camera shop and see 
what kind of adhesives they have available for splicing film.

Absolutely correct, it's a great salt substitute. She surely doesn't need  
lab grade salt though. KCl is sold by the brand name Lite Salt in many  
grocery stores. The grocery store version also has Iodide for the benefit

     Some work on metals is definitely inorganic chemistry, some is
definitely physical, and a lot of it falls into the vast grey area in
between.

     That's right.  In fact, stereochemistry becomes vastly more
interesting once you leave the first row of the periodic table.  The
reason that stereochemistry is usually first learned in organic class is
probably simply that organic chemistry is usually studied before
inorganic.

I normally call it PET (PolyEthylene Terephthalate), but the letters below 
the recycle symbol say PETE for the same material.

All true.

Kodak is certainly a big player in the polyester market (they also use it for 
film), but so are DuPont and Hoechst-Celanese among others.  Kodak, DuPont, 
Himont, and my company (Amoco) are all major manufacturers of purified 
terephthalic acid, one of the raw materials that is used in making polyester.
