Appeal No. 1996-1813
Application No. 08/117,453
calibration for the octane property. (Specification page 9,
lines 17-27).
Representative claims 1, 8, 9 and 11 are reproduced
below:
1. A system for the determination of at least one
property of liquid hydrocarbon mixtures by spectral
absorption comprising in combination:
A. a multivariate spectrophotometer operably
connected to measure said property;
B. at least two sources of reference liquid
hydrocarbons having different known values of
said property, said sources communicating with;
C. prototype injection means for automatically
sequentially injecting a plurality of said
reference liquid hydrocarbon mixtures into said
multivariate spectrophotometer for calibration
of said system over a range of said property.
8. A system according to claim 1 wherein the system is
substantially enclosed in hermetic cabinets having
cabinet purging means and said spectrophotometer
comprises a near infrared spectrophotometer.
9. A system according to claim 1 additionally
comprising in combination the following elements in
fluid communication.
A. Sample supply means (20); upstream of the
following which are connected in series
B. Sample filter means (70); and
C. Sample temperature controller means (96); and
D. Degassing means (110); all upstream of
