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

                           The metering apparatus 201, 203, and 205 are each automatically controlled by                            
                   control system 250 which preferably includes a microprocessor (specification, p. 19, lines                       
                   8-11).                                                                                                           
                           The appellants define “program control” as meaning that the equipment used to                            
                   provide the plurality of lubricating oil compositions is automated and controlled by a                           
                   microprocessor or other computer control device (specification, p. 5, lines 4-7).                                
                           Kolosov discloses systems and methods for screening a library of material                                
                   samples for a rheological property such as viscosity (abstract).                                                 
                           Kolosov discloses that the invention may be used to screen or test flowable                              
                   materials such as lubricants (p. 4, para. 42).                                                                   
                           The invention disclosed in Kolosov has particular utility in connection with the                         
                   screening of a number of different material forms including oils (p. 4, para. 43).                               
                           The Kolosov invention can be used to analyze the resulting properties of a                               
                   particular flowable sample material or the relative or comparative effects that an additive                      
                   has upon a particular flowable sample material, e.g., the effective of a detergent, a flow                       
                   modifier, or the like (p. 4, para. 43).                                                                          
                           An additive is defined as any substance incorporated into a base material, usually                       
                   in low concentrations, to perform a specific function, e.g., antioxidants, stabilizers,                          
                   preservatives, dispersing agents, viscosity-index improvers, etc.  The Condensed

                           According to the invention of Kolosov, a plurality of samples may be employed.                           
                   For example, four samples may be employed, one control sample and three varied
