Talk:Positive locking device

Reason for "positive" in the name
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: It seems likely that these use "positive" in their names for the same reason.
 * "positive displacement pump" (synonym for Moineau pump) and
 * "positive control" (in the context of factory automation lines as mentioned here at 1m10s).
