.~ Having member which crosses the plane of another member (e.g., T or X cross section, etc.)
DEFINITION
Classification: 428/598
(under subclass 544) Subject matter wherein the material has a variation in thickness representable by an alphabetical
symbol having a crossbar more or less perpendicular to another stroke of the letter, e.g., E, F, H, I, K, T, X or Y.
