Yes, this patent is for a linear version, what one might term an
'inchworm'. The results are consistent with my own calculations. The
Lorrey Drive, which is a rotary model in several versions, isn't quite
so fabled. I do have a pair of prototypes of the hydraulic version
built to operate side by side (cancelling out each others torque). I
have not, as yet, been financially fluid enough to pay for a test program.
