         Application No. 10/120,708                                                 

              (b) a helical purifier tube assembly which is disposed in             
         the interior of the vessel, wherein the maximum outer diameter of          
         the helical purifier tube assembly is larger than the inside               
         diameter of the cylindrical neck, wherein the tube has a first             
         end and a second end, and wherein the first end is in fluid flow           
         communication with the interior of the vessel;                             
              (c) one or more materials disposed inside the helical                 
         purifier tube assembly, which materials are capable of                     
         selectively removing impurities from the fluid; and                        
              (d) a valve comprising a body, an inlet, and an outlet,               
         wherein the valve body can be sealably connected to and                    
         disconnected from the cylindrical neck and wherein the second end          
         of the helical purifier tube assembly is connected to the inlet            
         of the valve, whereby the fluid in the interior of the vessel can          
         be withdrawn through the helical purifier tube assembly and                
         delivered through the outlet of the valve to the exterior of the           
         vessel.                                                                    
              The examiner relies upon the following references as                  
         evidence of obviousness:                                                   
         Horner et al.                 1,821,549              Sep. 1, 1931          
         (Horner)                                                                   
         Visceglia et al.              4,133,762              Jan. 9, 1979          
         (Visceglia)                                                                
              Appellants' claimed invention is directed to a fluid storage          
         and purification system comprising a cylindrical vessel and a              
         helical purifier tube assembly that is disposed in the interior            
         of the vessel.  Materials, such as absorbent and adsorbent                 
         materials, are disposed inside the helical purifier tube assembly          
         to effect removal of impurities from the fluid.                            
              Appealed claims 1-3 and 9-11 stand rejected under 35 U.S.C.           
         § 103(a) as being unpatentable over Horner in view of Visceglia.           
                                        -2-
