Well, if I read your question right....
Huss would make the standard Top Spin (Ripsaw at Alton , Ramses at CWoA, Twister at SF New England and Great Adventure to name a few)
As far as "3D" (I'd say independent arm)
Zamperla has the Windshear - Flip-N-Out owned by Reithoffer Shows
Moser has the Loop on Top - Superman II at Prater
Moser also has a mini LoT called Maverick - Twister at Rye Playland (now removed)
Vekoma has the Super Flip - Wipeout at Dreamworld
I'm kind of a big flatride loser, if you showed me a photo I'd be able to tell you who made it :X
(Like how most people have a coaster count... I've started this horrifying "All ride" count -
