paragraph."). Accordingly, the rejection of claims 3,
6, and 7 is reversed.
Indefiniteness
Claim 1
The Examiner states that "rearward (R) and radially
outward (A) directional components" of a "cone element" in
claim 1 is unclear, because a cone is not a vector (EA5).
We consider the limitation to be clear by itself and
especially when viewed together with the drawing. The
limitation defines the orientation of the cone.
The rejection of claim 1 is reversed.
Claim 3
The Examiner states that the term "semi-circular
cross-section" and the language "completely filled with
solid material" in claim 3 is indefinite (EA5).
We find nothing indefinite about the language. The
"band means" refers to the volume of material 40 lying
outside the cylinder 41, not the whole cross section shown
in figure 2A. The band is solid as shown in figure 2A.
