Appeal No. 95-0916 Application 07/803,530 appellants’ specification makes it clear that the baffle enclosure is a tube 100 having apertures 110 which directs the flow of gas to a particular location and in a particular direction, and is something in addition to the various screens (see, e.g., pages 6 and 7). We can think of no circumstances under which the artisan, consistent with the appellants’ specification, would consider the filter layers 44, 52, 54, 50 and 56 of Goetz and the filter layers 11 and 13’ of Jorgensen to be “baffle enclosures” as the examiner contends. In Goetz there is nothing which can be fairly considered to be a baffle enclosure and in Jorgensen the member 12’ is the baffle enclosure. Turning to the proposed combination of references, we observe that Goetz and Jorgensen are directed to two different types of gas generators. That is, the gas generator of Goetz is designed for “cylindrical radial flow” (column 1, line 42) of gas through all the screens, including screen 48 which the examiner considers to be a cooling screen. On the other hand, the gas generator of Jorgensen is designed for circumferential flow of gas 6Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
