How would one get a copy of SAE920234?

I see, so those R values you mentioned were internal Nernst cell
resistances at diff. Temps, NOT heater resistances. Yeah, that's a whole
nother story. It makes more sense now. Those would be internal R's of
the Nernst cell 'battery' at diff. temps.

OK, gotcha. No problem, I was just fishing for clarification.

eXcellent! Nuthin like hearing it from the electro-chemical types, to
stimulate some thot. I'd sure like to understand this oxygen ion pump
gizmo a tad better.

Nah, he's truly a sphincter, methinks, BUT knowing more may provoke him
to disclose more, just to prove he knows more than I do! Vee haf vays of
dealing vis his kind! Hee hee.

Thanks for more info. I jus luv a mystery.
