PATE, Administrative Patent Judge.
FINAL DECISION UNDER 37 CFR § 1.658
This is a final decision in Interference No.
103,322. The subject matter at issue is a baffle plate for
installation in the aggregate veil zone of an asphalt mixing
drum. The baffle plate interrupts the aggregate veil or
curtain permitting a tunnel of unimpeded gases to reach the
gaseous effluent end of the drum. This enables the operator
to raise the temperature of the exhaust gases to prevent
condensation in the baghouse.
The count of the interference reads as follows:
Count 1
Apparatus for modifying a veil of falling materials
generated in a drying and heating region of a substantially
horizontally disposed elongate drum of a drying and mixing
apparatus, within which drum the drying and heating is
effected by a stream of hot gases flowing longitudinally of
the drum and traversing the length of the veil of falling
materials, the apparatus for modifying the veil comprising:
at least one baffle plate supported within the
drying and heating region of said drum for extending at least
partially through the veil of falling materials; and
a support for supporting said at least one baffle
plate for pivotal movement about an axis disposed
