               The invention pertains to a pressure relief system for a               
          control system which houses electrical components.                          


               Independent claim 1 is reproduced as follows:                          
               1.   A pressure relief system comprising a control system              
          which includes a housing, a housing chamber located in said                 
          housing, and electrical equipment located in said housing                   
          chamber, and a valve system having a pressure relief device,                
          wherein said housing chamber is connected via a connecting                  
          device to said pressure relief device.                                      

               The examiner relies on the following reference:                        
          Ruchser et al. (Ruchser)           4,345,620                Aug.

               Additionally, the examiner relies on admitted prior art                
          [APA], related to an admission regarding gas dryers at page 5,              
          lines 15-24 of the specification.                                           


               Claims 1 through 4 stand rejected under 35 U.S.C. 102(b)               
          as anticipated by Ruchser.  Claims 5 through 12 stand rejected              
          under 35 U.S.C. 103 as unpatentable over Ruchser in view of                 
          APA.
