          Application No. 08/422,840                                                  


                            The anticipation rejections                               
               Turning first to the examiner's rejection of claims 1                  
          through 12 and 14 through 20 under 35 U.S.C. § 102(b) as being              
          anticipated by the Seliger patent, Seliger (Figure 2)                       
          discloses an apparatus for cranking the rotor of a turbo                    
          machine, the apparatus comprising a drive shaft (27) rotatably              
          mounted in a sleeve (24) and having a friction wheel (26) on                
          one end thereof for engagement with the rotor cranking surface              
          (23).  The sleeve and drive shaft are mounted in a housing                  
          (31) having an arresting means (22) at one end thereof for                  
          fixing the apparatus in an opening (24') of the compressor                  
          casing at an angle.  The apparatus is provided with a thrust                
          piece (34) biased by a coil spring against the sleeve (24).  A              
          nut (33) screwed over a tubular extension (32) is used to                   
          adjust the preload on the coil spring to thereby adjust the                 
          contact pressure of the friction wheel on the rotor surface.                
          A square-head pin-type extension (18) of the drive shaft                    
          extends through a handle (12') provided with a flange (17).  A              
          crank apparatus (Figure 1A) provided with a crank (41), a                   
          fitting (40) having a square-shaped socket adapted to                       
          accommodate the extension (18) and a casing (44) is secured to
