Can you help?

Call me a total retard if you wish but does anyone know what type of ride Ripsaw (Alton Towers)is? or Rameses Revenge (Chessington)for that matter or who makes it. I realise not many of the Americans will know what I am talking about but surely there is someone out there who can tell me, I don't know why I want to know, curiousity I guess.

DAMN YOU ROMANIA!

I'm pretty sure they are like the Gravitron on RCT. As for the company could it be Huss of Germany? I know a few companies build them. I think the Hang Time at Dorney Park is made by Huss. Correct me if i'm wrong.
