After a couple of minutes' thought, the only examples I can come up with are "other than" and "different than" (I wouldn't personally use the latter -- I'd normally say "different from" -- but I think it's more common in American English).
"I don't know any languages other than English."
"Why should he be any different than the rest of us?"
... a further thought ... apparently "rather" is by derivation a comparative form of "ready", but in modern English it doesn't seem to have quite the same nature as the ordinary comparatives ("more", "better", "easier" etc.), so perhaps uses with "rather" might count.
