摘要:
A stormwater treatment system includes water treatment media that defines a helical flow path within a conduit. The water treatment media may include a plurality of helical water treatment media components that are constructed and arranged to seal against an inside surface of the conduit. The individual helical water treatment media components may be installed in situ within the conduit when the conduit is positioned within a chamber having an access opening, and periodically removed and replaced by passing the components to the access opening. The components further may have a flexible frame, which allows the water treatment media to dynamically adjust to swelling of the filtration media and other forces that may occur during use. The performance of the system may be adjusted by adjusting the helical pitch of the helical water treatment media components.

A surface of a photovoltaic cell is coated with a solution that includes barium titanate to reduce reflection of sunlight that is incident on the surface. The solution may include a base of polydimethylsiloxane and carbon nanotubes. The process may be used in the fabrication of new photovoltaic cell assemblies, or to retrofit existing assemblies in situ.

摘要:
A hot fill type plastic container includes a bottom portion and a main body having a vacuum uptake portion that is bounded by upper and lower horizontal grooves. The vacuum uptake portion has four side panel portions, and each of the side panel portions has at least one vertical groove defined therein. The vertical grooves are substantially centered with respect to the side panel portions. No surface features other than the vertical grooves are included on the side panel portions. The main body further includes upper and lower round portions that are respectively positioned above and below the vacuum uptake portion.

A blow molded plastic container includes a main body portion that has a substantially rectangular shape when viewed in transverse cross-section. A plurality of side panels are defined on the main body portion. At least one of the side panels has a longitudinally oriented concave scoop that extends continuously from an upper portion of the side panel to a lower portion of the side panel. The side panel further includes a first pair of longitudinally oriented concave ribs that are positioned adjacent to an upper portion of the scoop and a second pair of longitudinally oriented concave ribs that are positioned adjacent to a lower portion of the scoop.
