    摘要: A filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face of the filtration media pack to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered fluid flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered fluid flowing out of the second portion of the plurality of flutes so that fluid passing into one of the first face and the second face of the media pack and out the other of the first face and the second face of the media pack passes through media to provide filtration of the fluid. The filtration media pack can be provided with increased filtration media compared with commonly used z-media packs. Techniques for increasing the amount of filtration media available for filtration include increasing the flute density, reducing masking, adjusting flute width height ratio, increasing flute density, adjusting flute shape, and reducing plug length. Techniques for increasing performance while reducing initial pressure drop are also provided. A filter element containing the filtration media pack is provided, and the filter element includes a seal member extending around a periphery of the filtration media pack. A method for manufacturing a filtration media pack and a method for using a filtration media pack are provided.

    摘要: An air filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face of the filtration media pack to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered air flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered air from flowing out of the second portion of the plurality of flutes so that air passing into one of the first face and the second face of the media pack and out the other of the first face and the second face of the media pack passes through media to provide filtration of the air. The fluted sheet includes repeating internal peaks facing toward the facing sheet and repeating external peaks facing away from the facing sheet. In addition, the fluted sheet can include at least one ridge extending along at least 50% of the flute length between an internal peak and an adjacent external peak. Additional characterizations of an air filtration media pack, air filtration media, and methods of making and using are provided.

    摘要: A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles includes a composite bed system having a plurality of elevations and comprising a first layer beneath a second layer. The first layer includes a deformable material configured to collapse when subjected to vehicle loads, and the second layer includes a pedestrian cover surface over the deformable material that conceals the deformable material. The pedestrian cover surface is configured to support pedestrian traffic over the deformable material without permanently collapsing the deformable material and to collapse along with the first layer when subjected to vehicle loads. A structure beyond the bed system is provided to resist the impact of a vehicle that has traversed the bed system.

    摘要: In a film wrapping machine for wrapping packages in stretchable film, a monitoring system is provided to generate a signal each time film is drawn into the machine. If no film is drawn into the machine indicating that the film source has expired, broken or otherwise become disengaged from the film feeding apparatus for the wrapping machine, the machine is stopped. The film draw into the machine is monitored by an electrical switch which is coupled to a tensioning roller, the motion of which is adjusted to activate the switch each time even at least a minimum length of film is drawn into the machine.
