Filed:

Jun 24, 2004

Appl. No.:

10/876242

Inventors:

Wallace J. Poole - Michigan Center MI, US
James R. Abbott - Jackson MI, US
Gabriel A. Kuschel - Stockbridge MI, US

Assignee:

Tenneco Automotive Operating Company Inc. - Lake Forest IL

International Classification:

F28D 7/02
F01N 7/08

US Classification:

165163, 165135, 181248

Abstract:

A combined muffler and heat exchanger apparatus is provided. The apparatus includes a housing defining a heat transfer chamber and an acoustic attenuation chamber separated by a partition. A flow regulator and a fluid transport member are disposed within the heat transfer chamber. The flow regulator is adapted to regulate the flow of a first fluid, such as a heat source, between an input end of the housing and the partition. The fluid transport member is adapted to contain the flow of a second fluid. An acoustic regulator is disposed in the acoustic attenuation chamber and extends longitudinally from the partition to an output end of the housing. The acoustic regulator is a metal tube including a plurality of apertures adapted to attenuate exhaust stream acoustics associated with an automotive vehicle power source.

Appl. No.:

7/751876

Inventors:

James R. Abbott - Jackson MI
Benny J. Snider - Brooklyn MI

Assignee:

Tennessee Gas Pipeline Company - Lincolnshire IL

International Classification:

F01N 108

US Classification:

181265

Abstract:

A muffler of the type used to attenuate exhaust gas noise in exhaust systems of automobiles, trucks, or the like, particularly characterized by a gas flow conduit which is axially slotted and laterally flattened to form a closure and a pair of openings axially inward of the closure, wherein the end walls of the shell are pressed into engagement with the conduit ends to close the conduit and support the conduit.

Inventors:

James R. Abbott - Jackson MI

Assignee:

Tennessee Gas Pipeline Company - Lincolnsire IL

International Classification:

B23P 1500
F01N 328

US Classification:

29890

Abstract:

A method of assembling a catalytic converter by inserting a catalyst substrate and surrounding support mat through the open end and into the central portion of an oval sheet metal tube, after which the reduced section and longitudinal ribs are formed in the central portion of the tube to compress the mat and securely engage the substrate, and the ends of the tube are pinched together to form sealed end closures with gas flow passages therein.

Appl. No.:

7/483399

Inventors:

James R. Abbott - Jackson MI

Assignee:

Tennessee Gas Pipeline Company - Lincolnshire IL

International Classification:

F01N 310

US Classification:

422171

Abstract:

A catalytic converter of the automotive type comprising a reduced central oval section that compresses a support mat around a catalyst substrate, the reduced central section comprising radially inwardly biased ribs that are parallel to the longitudinal axis of the converter. The converter can be made by inserting a catalyst substrate and surrounding support mat through the open end and into the central portion of an oval sheet metal tube, after which the reduced section and longitudinal ribs are formed in the central portion of the tube to compress the mat and securely engage the substrate, and the ends of the tube are pinched together to form sealed end closures with gas flow passages therein.

Appl. No.:

7/724387

Inventors:

James R. Abbott - Jackson MI

Assignee:

Tennessee Gas Pipeline Company - Lincolnshire IL

International Classification:

B21D 5300

US Classification:

29890

Abstract:

A catalytic converter with a one piece housing is made by inserting catalyst elements into opposite open ends of a sheet metal tube until their support mats abut against preformed annular ribs after which annular ribs are formed in the tube to engage the other ends of the support mats and the ends of the tube are pinched together to form sealed end closures with gas flow passages in them.
