However, it is an open-book test to obtain a license. Not very difficult to
pass. <g>

The R12 "drop-in" replacements have numerous pitfalls like th one you
mention. Try and put R134a into an R12 system in you car, and it will all
leak out through the hoses, since the new stuff is a smaller molecule.
Also, the oils used to lube the comressor for R12 are distructively
incompatatble with the oil required for R134a.
This is part of why I am ditching my old vintage cars for a new, leased
Saturn. No headaches and cold AC! I'm also interested in an electric car
called the Sparrow.
But, unless they have come up with a compact flourescent light bulb that
fits in old fixtures and recessed ceiling lights, I can't use them. I like
the color of halogen lights anyway.
OM content - I shot a roll of Tmax 400 using yellow and green filters (not
at the same time). Mostly I like shooting in the early morning, and I like
sculpture and architecture as subjects. My wife did a "geese" project
today. I went along and shot some "royal gold" ("royal treatment"??) 400.
What with the increased UV penetration from all that R12 leaking out of old
cars driven by poor people which R12 regulations were adamantly resisted by
the military industrial complex, I used a UV/haze #1 filter (passes 400V
I believe) instead of the usual UV/slylight. I use Tiffen filters. I may
try the #2 UV/haze sometime. Do UV filters improve/alter/maim B&W film???
Be seeing you.
