Abstract:
An apparatus and method for breaching and venting sealed inner containers disposed within a drum, where the drum is evacuated to created a pressure differential resulting in expansion and rupture of the inner containers. The temperature may also be reduced to below freezing in the drum to reduce the elasticity of the inner containers, and the drum may also be pressurized to implode and rupture the inner containers.

Abstract:
A liquid containment device for capturing and retaining any liquid falling into the device, such as from a leak, spill or run-off of another liquid container, where the device is designed to fit between the parallel rails of a railroad track with a railroad car positioned above, comprising a generally rectilinear pan or tray and gasket members sealing the space between the pan and the rails. Multiple pans may be connected in line through connector fittings in their end walls, or drain conduits may be connected to the fittings for removal of the liquid from the pan. Apertured grating members and absorbent mats may be placed within the pans. The pans may be used in conjunction with lateral pans positioned on the outside of the rails.
Abstract:
A drainfield funnel having a substantially horizontal drain surface sloping towards an opening, a substantially vertical rim around the perimeter of the drain surface and a tube extending down from the opening. The slope of the drain surface is less than 10 degrees. Preferably, the drain surface is uneven, having ridges and channels aligned with the opening. Additionally, a relatively horizontal lip extends from the top of the rim towards the interior of the device. In another embodiment, an annular shoulder connects the opening to the tube.
Abstract:
A modular liquid dam comprising a plurality of individual elongated members or segments that can be assembled in an end-to-end relationship to form a temporary liquid retainer or diverter on a substrate surface. The dam members are provided with one or more longitudinal bores or passages that reduce the amount of material in each member, thereby reducing manufacturing costs. The bore members are open on at least one end of the dam member such that a stiffener rod or rods of varying rigidity greater than the rigidity of the dam members may be inserted into the dam members to increase and vary the rigidity of the dam member as desired.
Abstract:
Fabrics that have been treated to create superhydrophobic, oleophobic and/or ice-phobic performance are manufactured or assembled in specific conforming shapes so they can be positioned on or pulled over and around certain objects for the purpose of making those objects superhydrophobic, oleophobic and/or ice-phobic so they are self-cleaning, water proof, ice-resistant, oil-resistant, corrosion barriers, etc.
Abstract:
A modular liquid dam comprising a plurality of individual elongated members or segments that can be assembled in an end-to-end relationship to form a temporary retainer or diverter on a substrate surface. The dam members are provided with a magnetic connection system having a magnet disposed within or exposed on the end of at least one adjacent dam member, the other adjacent dam member having a second magnet or metal member disposed within or exposed on its end, such that when the two dam members are abutted, the magnetic connection system maintains the dam members in abutting relationship. Structural mating members providing a mechanical or frictional fit may also be provided in the ends of the dam members to further enhance the connection in conjunction with the magnetic connection mechanism.
Abstract:
A storm water catch basin filter having a sampling port such that a real-time sample can be taken of water flowing through the filter without the need to remove the filter, the sampling port being an opening preferably covered by a removable closure member or a self-sealing valve.
