Appeal No. 2004-1666 Page 3
Application No. 09/586,912
In reaching our decision in this appeal, we have given careful consideration to
the appellants’ specification and claims, to the applied prior art, and to the respective
positions articulated by the appellants and the examiner. As a consequence of our
review, we make the determinations which follow.
The appellants’ invention deals with the problem of insect infestation in pad
mounted electrical transformers and the like, wherein the insects gain entry to the
housing through the opening provided for conduits. As manifested in independent claim
1, the invention comprises, inter alia, a flexible foam sealing material which expands in
its unset state and is flexible in its final set state and an insecticide dispersed in the
flexible foam sealing material for killing insects attempting to enter the housing, wherein
the set foam substantially seals around the conduits extending through the opening into
the housing as well as around the perimeter of the opening. The housing is selected
from the group consisting of secondary pedestal boxes of street lights, secondary
distribution pedestal boxes, telecommunications junction cabinets and pedestals, and
electrical distribution pad mounted switches and circuit breakers. The insecticide is
selected from the group consisting of acephate, carbaryl, pyrenone, aldicarb and
azonphos-methyl.
