Abstract: A composite oxidation catalyst for use in an exhaust system for treating an exhaust gas produced by a vehicular compression ignition internal combustion engine is disclosed. The composite oxidation catalyst comprises a honeycomb flow-through substrate monolith and two catalyst washcoat zones arranged axially in series on and along the substrate surface.

Abstract: Embodiments of the present invention provide a recessed mounting apparatus, a suspended ceiling and recessed mounting apparatus system, and a method of installing a recessed mounting apparatus. The recessed mounting apparatus includes a recessed mounting frame that forms a partially enclosed space with a lower perimeter defined by flanges configured to sit atop or otherwise connect with portions of a suspended ceiling frame. The recessed mounting apparatus includes or is attached to one or more attachment mechanisms from which equipment like temporary lighting, sound systems, and display projectors can be secured. To support the recessed mounting frame and attachment mechanism, one or more suspension support members are attached at a first end to the recessed mounting frame and at a second end to an overhead structural support.

Abstract: Doppler radar apparatus for use in a velocity measuring system for farm tractors and the like. The apparatus includes a dual mode conical horn having a flare angle substantially in excess of 12.5.degree., and a dielectric lens formed of a glass filled polymer. The doppler output signal provided by the RF transceiver associated with the dual mode horn is high pass filtered to remove low frequency signals therefrom. The horn is mounted in such a way that it is isolated from mechanical vibrations which would induce doppler signal frequencies in excess of the cutoff frequency of the high pass filter. Moreover, the horn assembly (which is aluminum) and a steel housing assembly are coupled together in such a way that thermal expansion and contraction will not loosen the friction fit between the two assemblies. The two assemblies are held together by a single, large diameter annular locking ring.
