Appeal No. 1998-3018
Application 08/457,328
THE INVENTION
The invention relates to the field of papermaking, and
more particularly to “a stock feed system for a multi-layer
headbox and a method in the operation of a multi-layer
headbox” (specification, page 1). Claim 1 is illustrative and
reads as follows:2
1. A combination of a multi-layer headbox including
inlet headers situated vertically one above another and a
stock feed system for feeding stock to the inlet headers of
the multi-layer headbox, the stock feed system comprising
a single fresh stock tank for retaining stock,
a branching member,
a first flow line having first and second opposed ends,
said first end of said first flow line being connected to said
single fresh stock tank and said second end of said first flow
line being connected to said branching member, a single flow
of fresh stock being passed through said first flow line from
said single fresh stock tank to said branching member and
being divided in said branching member into a plurality of
stock flows without storing said single flow of fresh stock
between said single fresh stock tank and said branching
member,
at least second and third flow lines each having first
2The phrase “said single flow of fresh stock” in claims
11 and 17 lacks a proper antecedent basis, an informality
which is deserving of correction in the event of further
prosecution before the examiner.
