Patent ID: 7861832

Claim:
A product comprising: a first component portion comprising a first material and having a flange protruding away from a body of the first component portion, terminating at a free end, and being tapered in height toward the free end, the flange having a plurality of ribs located on a surface of the flange and spaced apart from one another on the surface, each of the plurality of ribs taper in height toward the free end and taper in thickness toward the free end; and a second component portion comprising a second material different than the first material, the second component portion having a portion cast-in-place over at least part of the flange and over the plurality of ribs to form an interconnection between the first and second component portions so that relative movement between the first and second component portions is substantially prevented; wherein thermal expansion and contraction of the first and second component portions at the interconnection during use of the product is accommodated by the flange and the plurality of ribs.
