Appeal No. 1998-0873
Application 08/301,279
moving the nozzle with respect to the lamp envelope (FR2;
EA4). However, Mossel does not teach spraying the inside of
a tube with one or more "U" shaped bends. The Examiner
finds that Young discloses (at col. 5, lines 67-68) that
there should be a uniform coating of phosphor material
(FR2-3; EA4). The Examiner finds (FR3; EA5) that Muta
teaches an apparatus "to ensure a complete coating in a
simple manner not only for straight pipes but for bent and
curved pipes as well" (Muta, col. 2, lines 13-15). The
Examiner essentially concludes that it would have been
obvious to provide a uniform phosphor coating on a tube with
one or more "U" bends in view of Young and to modify the
tube spraying apparatus of Mossel in view of the teachings
of Muta (FR3-4; EA5).
Appellant argues (Br3):
The references do not teach how to phosphor coat
the inside of [the] lamp tube after it is bent into a
nonlinear shape. Moreover, it does not even suggest
the feasability [sic] of modifying their approach to
accomplish phosphor coating after the tube is bent.
The Applicant believes that the sewer painting
teachings of Muta do not suggest the modification or
combination of the references to arrive at the claimed
invention.
