the problems with the wc tdc's still exist. below is a blow-by-blow summary of all that we've tried..
keep in mind that all angles below are very approximate as there is no angular graduation on the wc gas valve:
date/time observation attempted fix result
------------------------ ------------------------ ------------------------ ------------------------
10/20/04 "bad" wc tdc turned wc gas left wc spectra
spectra in right flow rate from 4 still fine; no
sector to 5 liters/min change in "bad"
right wc spectra
10/21/04 still "bad" wc tdc shut off gas flow right sector
spectra in right entirely to left problem goes
sector sector; all gas away, but can't
then flows into take two-sector
right sector data like this
10/22/04 still "bad" wc tdc install movable right sector
spectra in right valve to allow problem not
sector us to choose fixed
the fraction of
gas going to
each sector;
valve initially
set so as to
form a 70 deg
angle with
mezzanine
10/23/04, 09:00 still "bad" wc tdc move valve so right sector
spectra in right as to form a 90 problem goes
sector deg angle with away, but can't
mezzanine; gas take two-sector
thus only goes data like this
to right sector
10/23/04, 17:00 still "bad" wc tdc move valve so right sector
spectra in right as to form about problem nearly
sector a 85 deg angle all gone, but
or so with left sector now
mezzanine starts to look
bad
10/23/04, 22:00 "bad" wc tdc move valve so right sector still
spectra in left as to form a 80 looks pretty
sector deg angle or so good, but left
with mezzanine sector shows
no change
10/24/04, 02:30 "bad" wc tdc move valve so right sector still
spectra in left as to form a 75 looks pretty
sector deg angle or so good, but left
with mezzanine sector shows
no change
10/24/04, 07:00 "bad" wc tdc move valve so ???
spectra in left as to form a 70
sector deg angle or so
with mezzanine
