Abstract: A power cable having a central ground conductor. Phase interweave power conductors are positioned about the central ground conductor. Individual phase interweave power conductors have the same diameter. The individual phase interweave power conductors have a cross sectional area which is optimized. Each of the individual phase interweave power conductors is configured to support 100% cross sectional usage to maximize power carrying capability. The power cable reduces the skin effect of the power cable and the proximity effect of the power cable.

Abstract: Exhaust purification system and methods for the reduction of emissions from an exhaust stream, including an upstream catalyst coupled with a passive NOx adsorber catalyst; means to contact the exhaust stream with ozone, to react NO in the exhaust stream with the ozone to produce NO2; and an SCR catalyst.

Abstract: An exhaust system for treating an exhaust gas produced by a diesel engine comprises: (a) an emissions control device (ECD) for oxidizing carbon monoxide (CO) and/or hydrocarbons (HCs), wherein the emissions control device comprises a platinum group metal (PGM) and a substrate, wherein the PGM is platinum, palladium or a combination thereof; (b) an injector for introducing an ammonia precursor into the exhaust gas, which is downstream of the ECD; (c) a first selective catalytic reduction (SCR) catalyst downstream of the injector, wherein the first SCR catalyst comprises a substrate and a first SCR composition, wherein the substrate is either a flow-through substrate or a filtering substrate; (d) a second SCR catalyst downstream of the first SCR catalyst, wherein the second SCR catalyst comprises a flow-through substrate and a second SCR composition; and wherein at least one of the ECD and the first SCR reduction catalyst has a filtering substrate.

Abstract: An electrical box suitable for safely and efficiently housing an electrical connection. The electrical box comprises a bottom and a plurality of adjacent side walls, each side wall being at least partially joined to the bottom and to each adjacent side wall to form an open box. Each side wall has a top edge wherein the top edges define an open box perimeter. A top is hingedly joined to one the top edges of one the side walls and is adapted to be moveable from an open position to a closed position. At least one the side walls comprises at least one notch, the notch comprising deformable plastic members that can be biased in an open position to define a conductor opening to receive at least one of the electrical conductors, the conductor opening being at least partially defined by the top when the top is in the closed position.
