Abstract
Abstract An oxidative catalytic converter comprising a shell, partitions within said shell which divide the interior into a plurality of sections which contain a catalyst material, an inlet to said shell, a valve located in said inlet which selectively admits gases passing through the converter to portions of the catalyst material in accordance with the gas flow rate or volume and/or temperature and an outlet from said shell for withdrawing gases therefrom.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
21 words
A cAtalytic converter in accordance with claim 1 wherein said diverting means comprises a valve disposed in said inlet conduit means.
Claim 2
Dependent Claim
50 words
A catalytic converter in accordance with claim 1 wherein said inlet conduit means comprises: an inlet plenum chamber in communication with the upstream ends of said catalyst beds; an inlet conduit connected to said inlet plenum chamber; and said diverting means comprises a valve disposed in said inlet plenum chamber.
Claim 3
Dependent Claim
179 words
A catalytic converter according to claim 1 wherein: said tubular shell is elongated and is generally rectangular in shape; said partition means comprises a perforate upstream end partition extending transversely across said shell, a perforate downstream end partition extending transversely across said shell and spaced apart from said upstream end partition, and a plurality of spaced apart imperforate partitions extending longitudinally of said shell between said end partitions to form said plurality of said catalyst containing sections; said inlet conduit means comprises an inlet plenum chamber connected to the upstream end of said shell and in communication with the upstream ends of said catalyst containing sections, and an inlet conduit connected to the upstream end of said inlet plenum chamber; said diverting means comprises a valve disposed in said inlet plenum chamber; and said second outlet exhaust gas conduit means comprises an outlet plenum chamber connected to the downstream end of said shell and in communication with the downstream ends of said catalyst containing sections, and an outlet conduit connected to the downstream end of said outlet plenum chamber.
Claim 4
Dependent Claim
37 words
A catalytic converter according to claim 4 wherein said valve is provided with a biasing means which normally biases said valve to a position to admit said exhaust gases to only one of said catalyst containing sections.
Claim 5
Dependent Claim
46 words
A catalytic converter according to claim 5 wherein: said catalyst longitudinally extending containing sections are stacked vertically within said shell; said biasing means comprises weight means which normally holds said valve in a position to admit exhaust gases to the lowermost of said catalyst containing sections.
