Application No. 09/996,842
that this recitation is inherent in the combination of
references because mounting a fan above the tubular radiation
units of De’Longhi would inherently influence the temperature of
the diathermal fluid contained therein. The examiner states,
that therefore, such a fan mounting would inherently enhance
thermal convection of the fluid. Answer, pages 4-5.
Appellant’s position regarding the rejection is set forth
on pages 4 through 7 of the brief. Appellant argues that the
modification suggested by the examiner would destroy the utility
of De’Longhi’s invention. Appellant argues that moving the
thermoventilation unit 6 from the bottom of the apparatus of
De’Longhi, to the top of the apparatus of De’Lonhgi, would cause
the unit to no longer be rotated so as to direct heated air
substantially parallel and adjacent to the floor of the room.
Appellant argues that, instead, heated air would be directed
parallel to the floor, but at a height several feet above the
floor. Brief, page 6. We are not convinced by this argument
for several reasons. As pointed out by the examiner, Woolley
specifically teaches to project air downwardly over the heat
transferring surfaces of the radiator and discharge air at a
predetermined point near the floor of the room to positively
heat a maximum volume of room air and to more uniformly
distribute heat throughout the room. Hence, one of ordinary
skill in the art would adjust the fan to project air downwardly
over the heat transferring surfaces of the radiator to heat a
maximum volume of air and to provide uniform distribution of
