Hi!: Nice concept, but Norton, in their experiences with the Sachs engines, attempted changing compression ratio of engine by screwing a plate in the rotor's surface. As it could have been expected, these plates detached and run away, leading the test people from Norton calling it: 'Rotary Grenades'.

Thanks, regards, + Salut

It is a Pats made in the US based on the Norton geometry like a lot of others.
