Appeal No. 1998-1553
Application 08/595,965
end of the passage (see Figure 3), splitters 60 in the flow
passage for splitting the fuel discharged from the outlet, and
an enclosure extending around the outer tubular member and
having an air receiving inlet (see Figure 1). As tacitly
conceded by the examiner, this burner assembly does not meet
the limitations in claim 11 relating to the frustro-conical
vane supported on the outer tubular member for stabilizing the
flow of the air.
Henderson discloses a carbon black reactor having a feed
introduction zone 1, a combustion zone 2, a carbon black
formation zone 3, a make oil inlet conduit and outlet nozzle
6, 8, an air conduit 9, a fuel conduit 10, a choke 14, and a
cone 20 mounted on a support 26, these components being
arranged as shown in Figure 1. Reactants introduced into zone
1 flow into the base 24 of the cone and out through a
truncated opening 23. The cone increases the velocity of the
reaction mass flowing therethrough (see column 3, line 46,
through column 4, line 9) and contributes to the ability of
the reactor to produce carbon blacks having different
structures (see column 5, line 64, through column 6, line 29).
