Abstract: An emission abatement assembly includes one or more DPNR devices for removing both NOX and particulate soot from the exhaust gas of an internal combustion engine. Reformate gas from a fuel reformer is used to selectively regenerate the DPNR device or devices. A method of operating an emission abatement assembly is also disclosed.

Abstract: An emission abatement system comprises a plurality of NOX traps positioned in a parallel flow arrangement, a desulfurization agent supplier for supplying a desulfurization agent, a valve arrangement for directing flow of the desulfurization agent and internal combustion engine exhaust gas between the NOX traps, and a controller. The controller is used to control operation of the desulfurization agent supplier and the valve arrangement to desulfurize the NOX traps. An associated method is disclosed.

Abstract: A catnip-filled toy (10) for cats which may be caused to roll, spin around, wobble, and slide when manipulated by the paw of a cat. The device (10) has a central hub (12) which is convex in shape. Extending horizontally from the central hub (12) are two hollow reservoirs (14) which may be filled with catnip (24). The central hub (12) and catnip reservoirs (14) are circular in shape when seen in side elevation from an end view, so as to allow the device to roll freely upon any smooth surface. The catnip reservoirs (14) have openings (20) through which the catnip (24) may be filled, emptied, and refilled and have a plurality of small holes (22) through which the scent of the catnip (24) inside may emanate outside. The catnip reservoirs (14) are attached by screwing together and may be detached by unscrewing. An alternative embodiment may include yarn (232), feathers, or other soft material extending from and attached to the outer ends of the catnip reservoirs (14).
