Filed:

Mar 21, 2005

Appl. No.:

11/085715

Inventors:

Robert J. Schellin - New Glarus WI, US

Assignee:

Fleetguard, Inc. - Nashville TN

International Classification:

F01N 3/02

US Classification:

60309, 60312, 181233, 181269

Abstract:

An exhaust water trap assembly has separated and spaced exhaust tubes, and a dome cap blocking entry of water to protect an upstream catalytic converter or soot filter. A first tube extends axially upwardly into a housing, and a second tube is spaced vertically thereabove. The dome cap on the top end of the first tube blocks exhaust flow axially upwardly therepast and blocks entry of water axially downwardly therepast.

US Classification:

422225, 422168, 422171, 60272, 60274, 60282, 60286, 60295

Abstract:

A reductant decomposition reactor for use in exhaust systems is provided that includes a middle tube portion formed with a reductant injector mount, an inlet tube, an outlet tube and a mixer. The inlet tube is formed at a first end of the middle tube portion and the outlet tube is formed at a second end of the middle tube portion and both are configured to create a sealed connection to different portions of the exhaust system. The mixer fits between the middle tube portion and the outlet tube and is configured to decompose the reductant in an exhaust stream. The injector mount comprises a tube like section that connects at a first end to the middle tube portion and at a second end to an injector port of the injector mount, and is configured to reduce recirculation flow patterns in the reactor, create a high velocity flow at an inner surface of the injector mount and thereby reduce the formation of reductant deposits.

International Classification:

F16L 23/00

US Classification:

285363, 285364

Abstract:

According to one embodiment, a flange joint for joining a first pipe to a second pipe includes an adapter coupled to the first pipe. The adapter includes a convex surface. The flange joint also includes a gasket with a first concave surface and a second convex surface. The first concave surface of the gasket is matingly engageable with the convex surface of the adapter. The second convex surface is matingly engageable with the second pipe. The gasket is supported on the first pipe. The flange joint further includes a clamp that includes a concave surface that is matingly engageable with the second pipe to secure the gasket to the adapter.

International Classification:

G08G 1/00
G06Q 20/06
G06Q 30/02
G06Q 20/08

Abstract:

This invention relates to systems and methods that provide compensation for participants in a cooperative driving or autonomous driving platoon based on their role within said platoon. Certain roles in these types of platoons provide a natural benefit. Other roles in the same platoon provide either less of a benefit, zero benefit or a burden. It is unlikely that a participating vehicle would willingly choose a role with a lesser benefit or burden; thereby significantly reducing the probability that a platoon could form. The system and methods within this invention overcome that economic disincentive; thereby removing an obstacle to cooperative driving or autonomous platoons.
