          Appeal No. 1997-1549                                                        
          Application No. 08/208,143                                                  

          mouthwash and tissues, or can be used to treat odors in                     
          household areas (page 5, lines 55-58). Gloffre teaches that                 
          the molecular sieves can be in shaped forms, i.e., monoliths,               
          but does not discuss how the shaped forms are made (page 5,                 
          lines 53-55).                                                               
               Hakansson discloses a method for making a cellular body                
          for adsorption of preferably organic substances in                          
          purification plants (abstract).  The cellular body is made by               
          binding layers, preferably layers of inorganic artificial                   
          fibers such as glass fibers, by impregnating the layers with a              
          sludge made of hydrophobic zeolite and an inorganic binder,                 
          and heating the impregnated body at a temperature at which                  
          sintering of the constituents begins to occur (page 2, lines                
          1-8 and 26-29; page 3, lines 1-6).  The zeolite can be a                    
          dealuminized zeolite, and the inorganic binder includes clay                
          (page 3, lines 16-19).  When the clay is a kaolin-type clay of              
          an alkaline nature or alkaline additives are used with the                  
          clay, “the pH value should be as high as possible without the               
          hydrophobic properties of the zeolite being negatively                      
          affected” (page 3, lines 20-23).  The impregnated cellular                  
          body “is fired at a temperature causing sintering together of
