Appeal No. 1997-3267 Application 08/324,386 and 6 stand or fall together, that claims 8 and 10 stand or fall together, that claims 9 and 11 stand or fall together and that claims 5 and 7 each stand or fall alone. We will first address the rejection of claims 4 through 6 under 35 U.S.C. § 112, first paragraph. The examiner objects to the specification as originally filed for failing to provide a basis for “the mixture of liquid and solid materials [being] added into the filter box at a pressure higher than atmospheric” (answer, page 3). As a result of the objection, the examiner rejects claims 4 through 6 under 35 U.S.C. § 112, first paragraph, which claims include the limitation of supplying a mixture of liquid and solid materials at higher than atmospheric pressure into the pressure chamber on an upper side of said filter belt. The appellant’s argument, in response, is that one of ordinary skill in the art would understand from the specification that the mixture for separation is maintained under relatively higher pressure both when supplied to the pressure chamber and within the pressure chamber itself. The fact that there may be other methods of supplying the mixturePage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
