Perhaps you could split the ends from the means. Ie, name something by material, shape, and effects (and not necessarily in that order). Examples:
- spherical rubber CPS
- cylindrical rubber CPS
- diaphragm rubber CPS
- metal spring CPS
- [regulated] air CPS
- metal spring dropoff piston
- air dropoff piston
- air dropoff cannon
- air dropoff separate PC
- air dropoff reservoir PC
materials - rubber, compressed air, metal
effects - CPS, with dropoff (which could be further split into those that obey Hooke's Law and those that obey Boyle's Law, ie elastic and air pressure systems).
Still, Ben's approach is a bit more conservative and common-sensical. Maybe there's no need to add terminology (especially acronyms) unless the old terminology is wrong, as it was with CVF.
Wow, typed this up two days ago, but Comcast was being weird.
