Are you sure you want to run the More horseshit. Measurement systems are not "copyrighted" by anybody. 1) As I keep pointing out US Copyright law (Title 17, US Code) has a section on what it can apply to... this aint it. 2) US government publications (except for a few statutory exceptions) are not subject to copyright. Once again, See title 17 of the US code. 3) I don't see any evidence that anything being discussed in the message has anything whatsoever to do with the US government. > risk of being put in prison or worse (being forced to use the spool > method of tank level mesurement) > > Gus > > > > > > Put a spool and line on a stepper motor.
