ignitable material and the means for igniting the
ignitable material, and a cap 11 welded to said base,
said cap enclosing said ignitable material and
maintaining said ignitable material in position on said
base, and a bottom 13 of said cap 11 being releasable
from said base as a unitary body under the force of the
combustion products of said ignitable material to enable
movement of the bottom of said cap away from said base,
see lines 8-10 of col. 2. However, Evans et al do not
disclose a resistive wire within the ignitable material.
Refouvelet et al teach a resistive wire located in a body
of ignitable material to be an art recognized equivalent
means for igniting an ignitable material. Furthermore,
Refouvelet et al also teach a base for an initiator
comprising a metal header 5, an electrical terminal 8a
connected to the header, an electrical terminal 8b
extending through the header, an insulating means 15
surrounding the electrical terminal 8b and the resistive
wire 9 connected to the header and electrical terminal
8b. To employ the art recognized equivalent base and the
resistive wire of Refouvelet et al in the Evans et al
initiator would have been obvious to one having ordinary
skill in the art at the time the invention was made. To
substitute the art recognized equivalent initiator formed
by the combination of Evans et al and Refouvelet et al
for the initiator and projectile 22 of Mossi et al would
have been obvious to one having ordinary skill in the art
at the time the invention was made.
The appellants argue (brief, pp. 10-13) that the applied
prior art does not suggest the subject matter recited in claim
14. We agree.
