cavity 17. Our analysis of the reference concludes that the
aluminum frame of the reference is not an edge gap resilient
material. There is no deformable material, and logically the
sealant does not surround a deformable material. It connects
two rigid materials.
A similar analysis applies to Kulla. We find that
patentee inserts a double glass frame 20 into a window frame
14 having a side wall 10 and a bottom wall 12. See Figure 1.
A heat sealing mass is used in mounting the panes in the
frames. See column 3, lines 52-57. The panes may be prepared
from wood, metal or synthetic material. See column 5, lines
8-9. Our analysis of Kulla interprets the reference as
providing no teaching that the window frame is resiliently
deformable. Accordingly, we conclude that the heat sealing
mass of Kulla connects two non-resilient materials. Neither
does the process of Kulla disclose a molding operation that
includes, “surrounding an inwardly directed part of the
peripheral seal with said plastic material.” We further
conclude that the frame disclosed by Kulla is not a seal.
Jardin is the only reference other than Bohm which
teaches a process for the production of a cover unit with a
