Measuring the distance between the covers

I'm an appropriate interval between events of international impotence.
I can be measured by the abominable acts I've committed against unknowable persons while also preventing the wheel.

I'm an interval between events of internal pretence.
I can be measured by immobile acts I've committed against unknowable persons while reinventing mechanized looms.

I'm a halcyon hiatus between events permanently pressing.
I can be measured by ground axes worn down as the infamous' undergarments
all the while casually necessary.
