Appeal 2006-2776
Application 09/970,279
Appellants’ claimed invention is directed to a reaction system
including a reaction chamber with a plurality of reactant inlets arranged to
combine reactants from different sources within the chamber such that the
combined reactants are directed along a path. A light beam source is
arranged for directing the beam at the combined reactants along the path.
The disclosed reaction system is said to be useful for forming nanoscale
phosphorescent particles, such as zinc oxide nanoparticles, via laser
pyrolysis (Specification 2, 3, and 7). Claims 21, 25, 27, 32, and 35 are
illustrative and reproduced below:
21. A reaction system comprising:
a reaction chamber;
a reactant delivery apparatus comprising a plurality of reactant inlets
into the reaction chamber, wherein the plurality of
reactant inlets are configured to combine within the
reaction chamber different reactants from separate
reactant sources along a combined reactant stream, such
that the combined reactants are directed along a reactant
path; and
a light source that is configured to direct a light beam at the combined
reactants along the
reactant path.
25. The reaction system of claim 21 wherein the reactant delivery
apparatus comprises two aerosol delivery apparatuses oriented to combine
two aerosol reactants along the reactant path within the reaction chamber.
27. The reaction system of claim 21 further comprising a shielding gas
port oriented to direct a shielding gas to limit the spread of the combined
reactants along the reactant path.
