.~ Macroscopically anomalous interface between layers
DEFINITION
Classification: 428/609
(under subclass 544) Subject matter comprising a plurality of layers or material having an interface between layers which is (1) nonplanar and noncylindrical, and (2) apparent to the naked eye.
(1) Note. Both contiguous layers or other components must conform to the irregularity.

138+, for a sheet or web containing at least one apertured component and one imperforate component.
171+, for a nonmetallic* sheet or web which varies in thickness, and which has a component conforming to the contours of a nonplanar surface.
567, for a stock-material* made by impregnating a metal into a consolidated metal powder composition having an interconnected void structure. 588, for a workpiece which may have an irregular interface between parallel nonfastened components.
612, for similar subject matter where the irregularity is merely a defined roughness or wave-form not apparent to the naked eye.
614, for a metallic* stock-material* having a component complete embedded within another component.
