Appeal No. 1996-3292
Application 07/991,467
capable of providing an adhesive and insulation layer, and we find no indication that there is a lack of
enablement of the composition as claimed.
Accordingly, rejection (1) will not be sustained.
Rejection (2)
The primary reference, Daume, discloses an inhibitor coating for solid propellant charges
comprising an insulating layer containing a binder and a filler, and a protective and adhesion layer. As
noted by the examiner, the binder of the insulating layer may be a polyether and a hardener (curing
agent) (col. 4, lines 1 to 4). Various materials are disclosed as possible fillers; Daume states that it is
known to use inorganic substances such as quartz (silica) (col. 3, lines 24 to 26), but that cooling
agents, particularly aluminum hydroxide, are more suitable than the inert fillers (col. 3, lines 48 to 65).
Appellants argue, first, that, "[u]nlike the claimed invention, the insulating layer disclosed in
Daume does not function as an adhesive or an insulator" (reply brief, page 6).
We do not agree because, first, it is not evident why an "insulating layer" would not be an "insulation
layer" as called for by the appealed claims. Secondly, although Daume also uses an adhesive layer, it is
disclosed at col. 4, line 6 et seq., that measures a and b should be undertaken with respect to the binder
of the insulating layer so that there will still be "satisfactory adhesion" (col. 4, lines 10 and 11). It
therefore appears that Daume's insulating layer has adhesive properties.
