A structured sheet cross flow media is formed with a first corrugated sheet having corrugations defining flutes angled in a first direction, a second corrugated sheet defining flutes angled in a second direction, and an interstitial planar sheet disposed between the first and second corrugated sheets. The interstitial planar sheet traps the flow of fluid or gas, such as air, entering one end of the media block within opposing flutes until the end of the interstitial sheet is reached, whereupon the fluid or gas can disperse between the intersecting flutes of the first and second sheets to provide a controlled dispersal of the fluid or gas. In one embodiment, the interstitial sheet terminates at an intermediate height in the media block to define the width of dispersion of air bubbles entering at a single source point.
A drift eliminator is formed from alternating curved spacers and corrugated spacer members to define tube-like passageways for the flow of air through an evaporative cooling apparatus. The formation of the corrugated blade member with beveled side walls places the back walls of the channels in a different plane than the front walls, with the lower edge of the front walls of the channels being positioned in a common plane along with the lower edge of the blade members. The angled side walls impede the formation of a film of water across the inlet opening into the channel, which requires an increase in horsepower for the fan to push air through the drift eliminator. Mechanical fastening devices molded into the respective members connects the corrugated spacer members and the blade members. A method of forming the corrugated spacer members to provide the angled side walls is also provided.
A spacer panel is incorporated into building walls to drain accumulated moisture from the wall structure. The spacer panel is formed with spacer members that project on opposing sides of a central planar web member. Each spacer member is formed independently and has a planar portion extending around the spacer member to provide a location for the insertion of apertures to allow moisture to pass from one side of the panel to the other. Each spacer member includes a planar surface that facilitates an application of adhesive for attachment of a barrier member thereto. The spacer members can be oriented in a herringbone pattern alternating on opposing sides of the central web member. The spacer members can be formed as a circular projection extending on one side of the central web with a truncated conical member projecting to the opposing side of the central web from the circular projection.

A nitrate recycle pump recycles about 75% of the effluent from the aerobic chamber back into the anoxic chamber to provide a nitrate source for the digestion of the BOD within the influent wastewater.
A baffle vent incorporates an integral drift blocker portion that is connected to the main body portion of the baffle vent by a generally planar transition portion to allow the drift blocker portion to move relative to the main body portion. The main body portion is formed with transversely extending stiffening ribs, while the drift blocker portion is formed with longitudinally extending stiffening ribs with the transition portion being devoid of stiffening ribs to maintain flexibility in the transition portion. The baffle vent structure can be formed in large sheets that span several roof rafters with multiple integral drift blocker portions formed to be positioned between the roof rafters. A deck baffle panel is also provided in a configuration similar to the main body portion to be installed beneath attic flooring in manufactured housing to allow an air flow to remove moisture from beneath the attic flooring.

A main body portion has a longitudinal axis and is positioned generally on a main body place. A spacer extends from the main body portion and a tail portion is hingedly mounted to the main body portion. The main body portion and tail portion include first and second side edges and a baffle width is defined between the first and second side edges. At least one line of weakness extends generally parallel to the longitudinal axis for modifying the baffle width to adapt to the rafter spacing.
An insulation block is utilized with a corresponding baffle vent having a transverse width that will span several roof rafters, as is provided for use with manufactured housing. The insulation block includes uniformly spaced vertical ribs that extend from one edge of the insulation block to the opposing edge thereof to stiffen the insulation block which is formed of vacuum molded polyvinyl chloride film. After the baffle panel is placed on top of the roof rafters, which is before the roof sheeting is applied, the insulation block is attached to the wall top plate with the top edge of the insulation block placed into engagement with the baffle vent. The top edge of the insulation block is configured to mate with the undulating configuration of the corresponding baffle vent, fitting between transversely extending stiffening ribs on the baffle vent, to prevent insulation from entering the soffit area.

The perforating wheels engage with the two backstop wheels through the two spaced apart openings. The endless feed belt has an upper portion and a lower portion. The lower portion of the endless feed belt is positioned above the support table. The protrusions on the lower portion of the endless feed belt engage with side stiffeners of the vent baffle sheet to move the sheet through the perforating wheels.
A vent baffle assembly provides air ventilation in a cathedral ceiling having rafter beams and roof sheathing. The vent baffle assembly includes a first vent sheet and a second vent sheet. The first vent sheet has first and second ends, first and second longitudinal ribs and a first lateral stiffener extending generally perpendicularly to the ribs. The second vent sheet includes third and fourth ends, third and fourth longitudinal ribs, and a second lateral stiffener extending perpendicularly to the ribs. The first vent sheet is positioned between adjacent rafters with the ribs oriented parallel to the rafters. The second vent sheet overlaps the first vent sheet with respective ribs interengaged to limit lateral movement of the first vent sheet relative to the second vent sheet. The first lateral stiffener engages the second lateral stiffener to limit longitudinal movement of the first vent sheet relative to the second vent sheet.
A water drain tank or channel module includes a structure having a top platen and a bottom platen, a plurality of generally vertical support members for supporting at least the top platen, the support members being retained in sockets on at least one of the bottom platen and the top platen, and optional side walls each including a water-permeable lattice member that is adapted to support an impermeable membrane or water-permeable geotextile material that is able of controlling the flow of drain water at least out of the module and restricting sediment from entering the module. An assembly of such modules to form a drain tank, channel or storage reservoir is also disclosed.
