Abstract: An electrical cable assembly, comprising a first electrical circuit further comprising a first plurality of insulated conductors longitudinally disposed to one another, wherein the first plurality of insulated conductors are cabled together in a bundle. The electrical cable assembly further comprises a second electrical circuit longitudinally disposed to the first electrical circuit, the second electrical circuit comprising a second plurality of insulated conductors longitudinally disposed to one another and cabled together in a bundle and a nonmetallic jacket surrounding the second plurality of insulated conductors and wherein the nonmetallic jacket isolating the first electrical circuit from the second electrical circuit. The electrical cable assembly further comprises a flexible interlocking metallic armor encasing the first and second electrical circuits.

Abstract: One or more systems are described for filtering waste water, and related methods. A system is described that includes at least one effluent feed line configured to receive an effluent liquid to be filtered and extending into a respective filter body, a particulate medium or bed disposed and retained in filter body by retention means for retaining the particulate medium or bed at or adjacent to a top portion of the filter body. A method is described that includes feeding effluent through an effluent feed line into a lower portion of a filter body in which is disposed a particulate medium or bed, retaining the particulate medium or bed in filter body while overflowing filtered output from the filter body through an outlet of the filter body, and initiating a media wash cycle.

Abstract: A method includes receiving a request to store an extensible markup language (XML) document in a repository. The XML document includes a plurality of markup elements. The method includes extracting a plurality of nodes from the XML document. Each node corresponds to a respective one of the plurality of markup elements, and the plurality of nodes are stored in a same memory block. The method further includes determining a set of memory requirements for each node. Each set of memory requirements includes a first memory space required to store a respective node, a second memory space required to store a set of direct child nodes of the respective node, and a third memory space required to store all descendant nodes of the respective node. The method includes storing each node in respective records in the repository based on each corresponding set of memory requirements for each node.
