Appeal No. 2005-1262
Application No. 09/864,809
THE INVENTION
The invention relates to “a molding system, and more
particularly to a valve assembly which suppresses an initial
surge of a fluid material component from a feed assembly”
(specification, page 1). Representative claims 1 and 17 read as
follows:
1. A valve assembly for a mix head assembly of a molding
system comprising:
a mix head comprising an inlet to a mixer section and an
outlet from said mixer section;
an input port to a passage;
a plurality of sequentially activatable valves communicating
with said passage to selectively suppress a flow of fluid through
said passage; and
an output port from said passage to said mix head.
17. A molding system comprising:
a mix head comprising an inlet to a mixer section and an
outlet from said mixer section;
an input port to a passage, said input port communicating
with a feed assembly;
a plurality of sequentially activatable valves each defining
a longitudinal axis, each of said plurality of sequentially
activatable valves include an opening transverse to the
longitudinal axis and alignable with said passage to selectively
suppress a flow of fluid through said passage;
a bias adjacent each of said plurality of sequentially
activatable valves to bias said valve toward an open position;
