Reason for "positive" in the name
[edit]Does anyone know for certain why this concept uses "positive" in its name?
If so please add tat info to the article.
There's also "positive" in:
- "positive displacement pump" (synonym for Moineau pump) and
- "positive control" (in the context of factory automation lines as mentioned here at 1m10s).
It seems likely that these use "positive" in their names for the same reason.
