brackets 13 and tie rods 13c (see Figure 3) or by guide screen
panels 14 and tie rods 16 (see Figure 4).
Given their alternating flat and undulating panel
construction, Adrian’s heating sheet bundles 12 fail to meet
the limitations in claim 1 requiring (1) a plurality of
profiled sheets mounted so as to be placed against each other,
and (2) pairs of profiled sheets on opposite sides of the
bundle wherein one of the paired profiled sheets is undulated
and the other is corrugated with the rolling depth of the
undulated sheet being greater than the rolling depth of the
corrugated sheet. The examiner’s reliance on Hubble to cure
these deficiencies is not well founded.
Hubble discloses a rotary heat exchange regenerator
having a spirally wound heat transfer disk or matrix.
Hubble’s disk is designed to avoid failures caused by commonly
occurring temperature differentials between the colder outer
rim of the disk and the hotter inner region. As explained in
column 1 of the reference, conventional disks comprise
alternating flat and corrugated metal strips which are
spirally wound and brazed together. “Although the corrugated
strip can give, the flat strip between the layers of
