Appeal No. 96-2099
Application 08/128,976
path of a selected collapsed carton in order to divert it into a
desired stacking channel (e.g., CH1L or CH1R). In Anschutz eggs,
after being weighed, are intermittently conveyed or indexed by
means of a chain conveyor 14 having pockets 46 (which hold the
eggs) through six discharge areas. At the desired discharge
area, an air nozzle 98 directs air across the top portion of a
stationary egg in such a manner so as to lift the egg out of its
pocket and transfer it across a short inclined crossover ramp 104
to a small rod-type conveyor 105 (see, generally, column 7; Figs.
15, 17 and 18). In our view, the examiner has impermissibly
relied on the appellant’s own teachings for motivation for
singling out the air nozzle from the disparate teachings of
Anschutz and incorporating it into the collapsed carton sorting
arrangement of Teegarden.
We also observe that, as illustrated in Fig. 7 of Teegarden,
the vertically oriented deflecting gates (such as DG1L and DG1R)
in conjunction with vertically oriented guides (such as 631 and
631) also function to keep the collapsed cartons in a vertical
orientation as they are being conveyed past the various sorting
channels. On the other hand, if air nozzles as taught by
Anschutz were substituted for the deflecting gates of Teegarden
