Abstract: A pumping system including a safety disconnect switch. The pumping system includes a variable frequency drive, an electrical submersible pump, and a motor connected to the electrical submersible pump. The pumping system also includes a safety disconnect switch disposed downstream from the variable frequency drive and upstream from the electrical submersible pump to prevent electric power generated by the motor from traveling upstream from the safety disconnect switch in the pumping system. A method of preventing electric power from flowing upstream from a safety disconnect switch in a pumping system includes the step of opening a circuit in the safety disconnect switch to prevent electric power from a motor attached to an electrical submersible pump from flowing upstream from the safety disconnect switch to other components of the pumping system.

Abstract: A ball safety netting system for use between a field and spectators and above an access/egress gate includes, for example, a main netting defining an opening over an access/egress gate, a gate netting positionable over the opening of the main netting, and wherein the gate netting is disposable in a first position operable to cover the opening in said main netting above the access/egress gate, and disposable in a second position operable to uncover the opening above the access/egress gate.

Abstract: An outdoor wall padding apparatus attachable to a vertical structure includes an upper padding section, and a lower drainage section disposed below the upper padding section. The outdoor wall padding apparatus is attachable to the vertical structure with the lower drainage section positionable adjacent to the ground and operable to allow water to pass into and out of the lower drainage section.

Abstract: An aftertreatment system may include an exhaust pipe and a mixing pipe. The exhaust pipe receives exhaust gas from an engine. The mixing pipe is disposed in the exhaust pipe and may include a tubular portion and a plurality of blades extending from a longitudinal end of the tubular portion. The tubular portion may include a plurality of openings extending through inner and outer diametrical surfaces of the tubular portion. The tubular portion and the plurality of blades may define an integrally formed unitary body.

Abstract: An aftertreatment system may include an exhaust pipe and a mixing pipe. The exhaust pipe may receive exhaust gas from an engine and may include a first portion defining a first longitudinal axis and a second portion defining a second longitudinal axis that is angled relative to the first axis. The mixing pipe may be disposed in the exhaust pipe and may include a tubular portion and a collar extending radially outward from the tubular portion. The tubular portion may include a plurality of openings and a plurality of deflectors. The plurality of openings may extend through inner and outer diametrical surfaces of the tubular portion. Each of the plurality of deflectors may be disposed adjacent a corresponding one of the plurality of openings.

Abstract: An exhaust treatment system may include gas, reductant and water conduits, a nozzle and a pump. The gas conduit may be in fluid communication with a source of compressed gas and may include a first valve controlling a flow of compressed gas through the gas conduit. The water conduit may be in fluid communication with a water source and may include a second valve controlling a flow of water through the water conduit. The nozzle may be in fluid communication with the gas, reductant and water conduits. The pump may be disposed between the nozzle and the second valve and may be in fluid communication with the reductant and water conduits. The pump may be operable in a first pumping direction to pump reductant from the reductant source to the nozzle and in a second pumping direction to pump reductant away from the nozzle and toward the reductant source.

Abstract: Methods and systems for assessing risks associated with a project. The method includes building a tier 1 library and a tier 2 library. The tier 2 library includes project templates specific to a service/product offering or project type. Building the tier 1 and tier 2 libraries includes identifying project activities associated with a project. The building also includes identifying at least one potential failure associated with each of the project activities, associating project activities that are determined to be generic to all projects with the tier 1 library, and associating project activities that are determined not to be generic to all projects with each of the project templates in the tier 2 library. The method also includes generating a project file from the tier 1 and tier 2 libraries, and calculating a baseline risk score for each of the project activities in the project file.

Abstract: A convex shaped apparatus transversed with a flat base at the bottom, sized and shaped to be fixedly attached to the base of a standard container. The apparatus may either be hollow (with the top open) to act together with the standard container to hold the contents or separately fixedly attached to the bottom of the standard container. The weight of the apparatus is sufficient to lower the center of gravity of the combined apparatus and standard container no matter whether the container is full, partially full or empty. The convex shaped surface of the apparatus, above the flat base of the apparatus, insures that the container is unstable when left unattended. In the event that the container fills with liquid such as rain water, it wall tip on its side if a curious child investigates and tries to get in the container. The tipping container allows the liquid to spill out rendering the container harmnless to a child and prevents the drowning of the child.
