Appeal No. 97-0690
Application No. 08/375,094
Like the examiner, we broadly view the applicator of Lockwood
as
a pulsating spraying device for applying a liquid material
(e.g., hot melt adhesive) to a work surface (19). See
particularly, column 1, lines 25-34, of Lockwood. The device
of Lockwood includes a housing (10) having an inlet (16) for a
liquid material under pressure, and a plurality of discharge
openings (28) for discharging the liquid material; an inlet
chamber (12) which communicates with the housing inlet; a
plurality of pulsating control chambers (23), each having an
inlet passageway and an outlet passageway as set forth in
appellant’s claim 1; and a plurality of “oscillating” members
(e.g., 32, 32a), one located in each of the pulsating control
chambers, “rapidly oscillated by the flow of liquid into the
respective pulsating control chamber via its inlet passageway,
to drive the liquid via its outlet passageway out of the
respective discharge opening in the form of pulses,” as set
forth in appellant’s claim 1 on appeal.
