Appeal No. 1997-0793 Application 08/107,633 separator is separated in the dust separator into a combustible gas stream, which passes through cooler 22, and a hot particulate stream (18). Step e: At least a part of the hot particulate stream from the dust separator is applied to the carbonization chamber by way of superheating chamber 24 and pipe 4 (col. 3, lines 16-20; figure 1).4 Appellant argues that Roetheli does not indicate what the combined stream is used for and that, therefore, the disclosure of a combined stream has nothing to do with the claimed subject matter (brief, page 8). This argument is not well taken because the relevant question is whether the applied prior art would have fairly suggested, to one of ordinary skill in the art, appellant’s recited combining and separating steps. As discussed above, these steps would have been fairly suggested to such a person by the applied prior art. Appellant further 4Appellant’s claim 1 does not require that the hot particulates are fed directly to the reactor or that the hot particulates which enter the reactor are in a stream which has the same composition as that which exits the separator. -7-7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
