APPEALED SUBJECT MATTER
Claims 1, 9 and 13 are representative of the subject matter
on appeal and read as follows:
1. A stream switching system, comprising:
a stream switching housing having at least one common stream
channel portion with a plurality of input ports and at least one
output port;
tubing connected at least one of said output ports,
said tubing at least in part being a pre-heat coil suitable
to heat a fluid sample traveling through said coil and to act as
a flow restrictor for flow restriction of said fluid sample, the
extent of said flow restriction sufficient to restrict said
sample flow to about 50-70 cc/min.
9. A stream switching system, comprising:
a stream switching housing having a common stream channel
portion with a plurality of actuatable input port and at least
one actuatable output port, each of said ports being actuatable
between an open position permitting the flow of fluid through the
port, and a closed position not permitting the flow of fluid
through the port;
a plurality of fluid flow actuation switches associated with
said actuatable ports, said fluid flow actuation switches
controlling the placement of said actuatable ports between said
open and closed positions, said fluid flow actuation switches
requiring an outside impulse to place said actuatable ports in
said open position.
13. A stream switching system, comprising:
a sample point location;
