Appeal No. 95-4615
Application No. 08/158,853
With respect to claim 1 through 19, the examiner states
that the Hawke reference discloses "all aspect of the [claimed
features] except [sic, for] the instantly recited... keyways
[and keys]..." According to page 7 of the specification, the
terms "keyways" and "keys" recited in claims 1 and 7 are
defined as follows:
As Figure 4 shows, the lower edges of the
panels are formed with beveled surfaces 50 to
facilitate installation. When adjacent side
panels are placed in position, the complementary
channels 46 and passages 48 become aligned and
form a keyway 44 accessible from the upper
surface of the panels. Castable refractory,
preferably KRICON 30 XR or KRIFORM 30 XR low
water vibrating castable, is placed into the
passages, flows into the channels, fills the
channels and passages, dries, cures and hardens,
thereby providing a structural connection among
the side panels, referred to hereafter as keys
45.
To remedy the deficiencies of the Hawke reference, the
examiner relies on the Beckman reference. Beckman discloses
using a shear link (keyways and keys) between "concrete units,
such as slabs, panels, etc...," to "add additional shear
strength and reduce the shear stress supported by the cement
grout in the joint" between adjacent concrete units. See
column 1, lines 40-50 together with columns 3 and 4. The
