Appeal No. 2004-1137 Application No. 09/734506 Kelvin, we note that Longsworth clearly indicates (col. 3, lines 43-53) that subsequent to supplying the liquid nitrogen, the combined effects of the cooling steps used therein achieves "a working temperature of less than 73º K. inside the Dewar, in less than 15 minuets." From this, we conclude that the mean or average temperature within the Dewar (50) just prior to sampling will be a working temperature of about 73º K. or slightly less and that the liquid nitrogen bath surrounding the submerged sample storage bottle (10) will likewise be at or near 73º Kelvin. Moreover, even if the temperature of the liquid nitrogen bath (51) is somewhat higher than the approximately 73º K. working temperature within Dewar (50), since the sample storage bottle (10) is entirely submerged in the liquid nitrogen, whatever temperature the liquid nitrogen bath is at will be the storage temperature of the sample within the storage bottle (10). Thus, the liquid cryogen (51) in Longsworth's sampler defines a "first cooling volume" that is "operable to cool the fluid sample to the storage temperature," exactly as set forth in appellant's claim 1 on appeal. In the reply brief filed October 17, 2003 (Paper No. 29), appellant has raised a second line of argument with regard to 1010Page: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: November 3, 2007
