DEFINITION

Classification: 209/699

Sorting items according to susceptibility to deform (e.g., malleability, hardness, compressibility, etc.), rupture, or vibrate:

(under subclass 606) Methods and apparatus wherein items are separated according to their susceptibilities to deform, rupture, or vibrate.
