                   Appeal No. 2007-0495                                                                                             
                   Application No. 10/699,510                                                                                       

                           Tubular line 111 is a conduit for communicating the base oil B to nozzle portion                         
                   113, and tubular line 121 is a conduit for communicating additive A to nozzle portion 123                        
                   (specification, p. 16, lines 2-3 and 6-8; Figure 1).                                                             
                           Nozzles 113 and 123 are preferably in close proximity so that base oil B and                             
                   additive A can be simultaneously dispensed in a test reservoir, or in the alternative, base                      
                   oil B and additive A can be sequentially added to the test reservoir (specification, p. 16,                      
                   lines 12-14).                                                                                                    
                           Metering pumps 112 and 122 determine the amount of base oil and additive                                 
                   dispensed.  The metering pumps can be computer controlled (specification, p. 16, lines                           
                   4-5 and 8-9).                                                                                                    
                           The base oil B and additive A are preferably combined in the reservoirs by                               
                   mixing, for example by agitation, static mixing, individual stirring of the contents of the                      
                   reservoirs (mechanical or magnetic stirring) or by bubbling the reservoir with a gas, e.g.,                      
                   nitrogen (specification, p. 18, lines 12-15).                                                                    
                           Optionally, base oil B and additive A can be combined prior to dispensing into the                       
                   reservoirs.  For example, a single dispensing nozzle having a mixing chamber can be                              
                   used, wherein base oil B and additive A are metered into the mixing chamber and then                             
                   dispensed through the nozzle into the reservoir (specification, p. 18, lines 16-19; Figure                       
                   2).                                                                                                              
                           As illustrated in Figure 2, conduits 202, 204, and 206 convey a quantity of base                         
                   oil B, a first additive A-1, and a second additive A-2, respectively, through metering                           
                   apparatus 201, 203, and 205, respectively (specification, p. 19, lines 2-5).                                     



                                                                 5
