          Appeal No. 94-3000                                                          
          Application 07/914,654                                                      


          section 112(6)").  According to pages 5, 6, 7 and 10 of the                 
          specification, the lifting means is described as follows:                   





               The invention further relates to an arrangement                        
               for carrying out the method mentioned in the opening                   
               paragraph, this arrangement being provided with a                      
               lifting member for lifting the substrates above the                    
               liquid and with means for gripping the dry                             
               substrates above the liquid.                                           
               ... On the lower side of the substrates, which                         
               in the known arrangement are taken from the liquid,                    
               a drop of liquid sticks.  In order to avoid this,                      
               the arrangement according to the invention is                          
               provided with a knife-shaped member, which supports                    
               the substrates when lifted from the liquid at those                    
               parts of the substrates which are the last to leave                    
               the liquid.  The drops then flow away via the knife-                   
               shaped member.                                                         
               ... Further, the arrangement comprises a                               
               lifting member 15, which can be moved upwardly by                      
               means of shafts 16, passing through the bottom 10 of                   
               the bath 2 and which are driven by driving means not                   
               shown.  Thus, the substrates 1 can be slipped or                       
               moved upwardly from the cassette 4 into the                            
               auxiliary cassette 11.                                                 
               ... According to the invention, this knife-                            
               shaped member 19 forms parts of the lifting member                     
               15 and the substrates are lifted from the liquid by                    
               the knife-shaped member 19.  The knife-shaped member                   
               19 is made, for example, of quartz glass and has an                    
               apical angle of less than 100 .  When the substrateso                                         
               are lifted from the liquid 3, the whole quantity of                    
               liquid now flows away from the substrate via this                      
               knife-shaped member 19.                                                
                                          12
