Appeal No. 1997-1734 Application No. 08/215,259 cylinder 100, a pump 102, a regulator 104, an extraction section 106, a nozzle 108, a pressure transducer 112, a flow transducer 118, and a control loop 116 (figure 1; column 7, lines 17-39). In another embodiment, Frank teaches the use of a heat exchanger 204 and preheater 211 to control the temperature of the fluid upstream of the extraction chamber (figure 3; column 8, lines 40-50 and 61-63). According to Frank, the extraction chamber is preferably actuated between two positions and that this actuation permits the chamber to be automated (column 8, line 66 to column 9, line 1). Frank further teaches that an “apparatus for automatically creating the high pressure seals necessary between chamber 210 and the vessel containing the sample” can be included (column 9, lines 1-4). Frank states that the vessel containing the sample is a “thimble,” which is preferably “a common vessel in an automated bench, permitting the same vessel to serve as a sample transport vessel, as part of a filtering apparatus” (column 9, lines 18-21). Also, Frank teaches that, in a preferred embodiment, the apparatus additionally comprises a queue which can collect multiple fractions in sample 10Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
