          Appeal No. 95-4152                                                          
          Application 08/042,044                                                      

          represent the inventors' own work and, thus, do not constitute              
          prior art.                                                                  


          Grouping of claims                                                          
               Appellants state under the Grouping of Claims that "[t]he              
          presumption set forth in 37 C.F.R. 1.92(c)(5) [sic,                         
          1.192(c)(5)] is correct with regard to the rejected claims"                 
          (Br17).  Nevertheless, appellants proceed to argue all of the               
          claims in each ground of rejection individually.  Since the                 
          examiner has treated all the claims, we consider the claims                 
          individually.                                                               


          Claims 1 and 7 -- Hanson                                                    
               Initially, there are several matters of claim                          
          interpretation with respect to claim 1.  First, the preamble                
          limitation "for being worn by a person in a heated environment              
          where stratified heat is present which increases vertically,"               
          is considered a statement of environment or intended use for                
          the apparatus and not a structural limitation.  Second, the                 
          limitation "wherein upon said head-protective helmet being                  
          present in said stratified heat an envelope of reduced heat is              

                                        - 5 -
