Minimum volume oven for producing uniform pyrolytic oxide coatings on capacitor anodes

Abstract

A pyrolysis oven provides uniform pyrolytic coatings on capacitor anodes. An oven chamber contains cross-flow blowers situated to provide uniform laminar flow of oven atmosphere over the objects to be treated. The top and side walls of the chamber meet in an inverted V such that when the blower operate, a vortex is created in the inverted V in the chamber.

1 - 14 . (Canceled)  
   
   
       15 . A process of producing uniform, laminar oven atmosphere flow over objects to be treated in a pyrolysis oven, said pyrolysis oven comprising a chamber formed by a top, a bottom, an entrance wall, an exit wall, a first side wall and a second side wall, wherein the top and at least the first side wall meet in a first inverted V shape, wherein the oven further comprises at least one cross-flow blower situated at the bottom of the chamber adjacent the first side wall, wherein the process comprises forming a first flow of oven atmosphere from the cross-flow blower up the first side wall of the chamber, the first flow of oven atmosphere creating a first vortex in the first inverted V, the first vortex forcing the first flow of oven atmosphere over the objects to be treated.  
   
   
       16 . The process of  claim 15  wherein the top and the first side wall meet in a first inverted V shape and the top and the second side wall meet in a second inverted V shape, wherein the chamber comprises first and second cross-flow blowers, the first cross-flow blower located in the bottom of the chamber adjacent the first side wall and the second cross-flow blower located in the bottom of the chamber adjacent the second side wall, wherein the process comprises forming a first flow of oven atmosphere from the first cross-flow blower up the first side wall of the chamber, said first flow of oven atmosphere creating a first vortex in the inverted V, said first vortex forcing the first flow of oven atmosphere over the objects to be treated, and the process further comprises forming a second flow of oven atmosphere from the second cross-flow blower up the second side wall of the chamber, the second flow of oven atmosphere creating a second vortex in the inverted V, the second vortex forcing the second flow of oven atmosphere over the objects to be treated.  
   
   
       17 . The process of  claim 15  further comprising heating the first flow of oven atmosphere.  
   
   
       18 . The process of  claim 16  further comprising heating the first flow of oven atmosphere and second flow of oven atmosphere.  
   
   
       19 . The process of  claim 15  wherein the objects are continuously moved through the oven chamber.  
   
   
       20 . The process of  claim 16  wherein the objects are continuously moved through the oven chamber.  
   
   
       21 . The process of  claim 15  further comprising adding a gas to the oven chamber.  
   
   
       22 . The process of  claim 16  further comprising adding a gas to the oven chamber
