Abstract: A compound honeycomb body comprising a first honeycomb section having a volume V1 and a second honeycomb section fluidly connected to the first honeycomb having a volume V2 is provided. The first honeycomb section comprises a low mass high porosity porous ceramic substrate. The second honeycomb section comprises a standard porous ceramic substrate. Wherein V1/V2 comprises a ratio in a range from about 50/50 to about 10/90.

Abstract: A low cost, plastic, one-piece paint tray, which is optionally disposable or reusable, is thermoformed or molded and has a roller platform hinged at one of its ends to a base for pivotal movement relative to the base between use and non-use positions wherein, in a use position, the roller platform is disposed within the base and releasably attached as by snap fastener means to the base and wherein, in a non-use position, the roller platform is disposed exteriorly of the base for ease of cleaning, storage and shipment, the base being configured to support the roller platform at an inclined angle relative to the base in the use position and to provide communicating chambers under the roller platform when the platform is in a use position to increase the paint holding capacity of the paint tray.

Abstract: Diesel engine exhaust filtration systems, and ceramic honeycomb wall flow exhaust filters for such systems, wherein the filters comprise axially centralized filter sections having a higher heat capacity and/or a higher gas flow resistance than peripheral filter sections disposed radially outwardly thereof, the filters thereby exhibiting increased resistance to thermal damage from filter regeneration over-heating.
