              Appeal No. 1999-0547                                                                 Page 6                 
              Application No. 08/615,790                                                                                  


              vertically, that is, such that the hopper walls do not intercept such a portion of the weight of            
              the ingredients as to allow generation of the undesired perturbations by the auger.  In this                
              regard, from our perspective not only is guidance provided in the specification for defining                
              “substantially vertically,” but McLeod represents the prior art over which the appellant                    
              believes his invention to be an improvement, in that it is clear from Figure 6 that the extent              
              of the variation of the elongated tubular hoppers from the vertical results in the weight of the            
              ingredients flowing therethrough being applied against the sloping walls of the hopper                      
              rather than against the auger.  This is precisely what the appellant wishes not to do, and                  
              provides the basis for our conclusion that elongated hoppers 134 and 136 of McLeod do                       
              not extend “substantially vertically upward.”                                                               
                     Since all of the recited structure is not disclosed by McLeod expressly or under the                 
              principles of inherency, the reference is not anticipatory and we will not sustain the                      
              rejection of independent claim 1 or, it follows, of claims 2-4, 6, 7, 9 and 10, which depend                
              therefrom.  We reach the same conclusion, for the same reasons, with regard to                              
              independent claim 11 and dependent claims 12-15 and 17.
