Abstract
Abstract An apparatus for decontaminating exhaust gases, such as in motor vehicles, a rigid metallic housing, a catalyzer body of the monolithic type placed in the housing which serves simultaneously as the outer wall of an exhaust gas conduit, a pair of annular pockets or chambers formed at the end portions of the housing, a resilient and corrugated or accordion-like compensating device placed in the pockets and a shell or sleeve surrounding the catalyzer body and having conical flange end portions cooperating with the resilient and corrugated compensating device for supporting the catalyzer body and the shell within the housing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
An apparatus for decontaminating exhaust gases comprising a monolithic catalyst body suitable for removing toxic gases from an exhaust gas passage, including an elastic holder, resiliently suspending said monolithic catalyst body, comprising: a rigid metallic housing having an inlet opening and an outlet opening and forming the outer wall of said exhaust gas passage; resilient means operable to provide resilient pressure to a support means and being disposed within said housing near said openings; a sleeve circumferentially disposed about the monolithic catalyst body and disposed in said housing therewith and including means operable to restrain substantial axial movement of the body relative to the sleeve, and said support means operable to support said sleeve, being disposed near an end of said sleeve and being operably engaged with said resilient means, said support means and said sleeve having matching annular chamfers at adjacent ends thereof interengaging under the pressure of said resilient means whereby said support means supports and centers said sleeve.
Claim 2
Independent Claim
161 words
An apparatus for decontaminating exhaust gases comprising a monolithic catalyst body suitable for removing toxic gases from an exhaust gas passage, including an elastic holder, resiliently suspending said monolithic catalyst body, comprising: a rigid metallic housing having an inlet opening and an outlet opening and forming the outer wall of said exhaust gas passage; resilient means operable to provide resilient pressure to a support means and being disposed within said housing near said openings; a sleeve circumferentially disposed about the monolithic catalyst body and disposed in said housing therewith and including means operable to restrain substantial axial movement of the body relative to the sleeve, and said support means operable to support said sleeve, being disposed near an end of said sleeve and being operably engaged with said resilient means, said support means and said sleeve having matching annular chamfers at adjacent ends thereof interengaging under the pressure of said resilient means whereby said support means supports and centers said sleeve.
Claim 3
Dependent Claim
22 words
An apparatus as claimed in claim 1, further comprising a heat resistant sealing material between said sleeve and the monolithic catalyst body.
Claim 4
Dependent Claim
16 words
An apparatus as claimed in claim 2, wherein said heat resistant sealing material comprises ceramic wool.
Claim 5
Dependent Claim
49 words
An apparatus as claimed in claim 1, further comprising at least one slot defined in said sleeve and extending between the ends thereof whereby a radial pressure component that results from the interengagement of said matching annular chamfers, presses said sleeve onto the circumference of the monolithic catalyst body.
Claim 6
Dependent Claim
25 words
An apparatus as claimed in claim 4, further comprising strip means for covering each said slot to restrain the escape of gases from said sleeve.
Claim 7
Dependent Claim
30 words
An apparatus as claimed in claim 4, wherein said resilient means comprises a resilient corrugated device operable to form a substantially gas-tight seal between said support means and said housing.
Claim 8
Dependent Claim
30 words
An apparatus as claimed in claim 1, wherein said resilient means comprises a resilient corrugated device operable to form a substantially gas-tight seal between said support means and said housing.
Claim 9
Dependent Claim
16 words
An apparatus as claimed in claim 7, wherein said resilient means comprises a resilient corrugated wall.
Claim 10
Dependent Claim
25 words
An apparatus as claimed in claim 7, wherein said resilient means comprises a flexible corrugated wall and a compression spring disposed around said corrugated wall.
