It’s the Garret turbine. There could well be more but they haven’t come to my attention.

Not sure which engines you mean with your question about direction of rotation. The Model A in a Pietenpol rotates the same direction as any other A, but I don't know about other aircraft engines. The answer would be found in the earliest years of powered flight, I'm sure.
