Abstract: There is provided in a standard ceiling system, having suspension rails or elements a movable air delivery diffuser resting on the suspension elements and a filter panel inserted into and retained between the suspension elements and the air delivery diffuser. The filter panel has a filter frame and an attached filter designed to be inserted into and retained on the suspension elements of the suspension ceiling. The filter frame has an inner face and an outer face with a filter media retained in the filter frame. The outer edges of the filter media are located and retained adjacent the filter frame inner face. The filter frame outer face has a flexible perimeter flange projecting outwardly from an uppermost portion of the filter frame outer face. This flexible perimeter flange can bend inwardly so as to be substantially flush with said frame outer face and can then flex back outward to engage the suspension elements.

Abstract: There is provided a process for forming profiled elastic laminates suitable for forming profiled elastic ear portions. The process comprises the steps of providing a continuous length of at least one elastic web material having a first width and a continuous length of a first extensible nonelastic web having a second width. The extensible web is extensible in at least the width dimension. The at least one elastic web material and the first extensible nonelastic web are joined to form a first laminate. The first laminate is cut into at least two adjacent continuous lengths of at least two nested profiled laminates. The nested profiled laminates each have at least one profiled edge. Adjacent profiled edges of adjacent profiled laminates are substantial negatives of each other. The adjacent profiled laminates are then physically separated from each other.

Abstract: There is provided an oil absorbing wipe material suitable for wiping a users' skin or hair and a method for their manufacture. The wipes comprise at least an oil absorbing porous film-like substrate of a thermoplastic material. Generally, the wipe changes transparency or color (a change in L* of about 10 or more) when loaded with oil to provide an oil absorption indication functionality. The wipe is formed by (a) providing a porous film-like substrate of a thermoplastic material capable of absorbing facial or body oils and changing transparency or color, and (b) coating the porous substrate with oil, either continuously or in regions, wherein the oil coating is not sufficient to change the transparency or color of the substrate such that it loses its oil absorption indication functionality. This oil coating being of a nature such that the coated porous substrate has an increased oil absorption indicating functionality.

Abstract: Tool rolls and methods of using the tool rolls to manufacture articles with one or more structured surfaces are disclosed. The tool rolls include an outer surface that, when used in connection with materials of the proper viscosity or formability, can form a structured surface on an article. Because the tools are manufactured in roll-form, they can be advantageously used in continuous manufacturing processes. Alternatively, discrete articles may be processed using the tool rolls. The tool rolls are constructed of a cylindrical base roll and are wrapped with one or more continuous wires in a modified undulating helical pattern. The modified helical pattern results in the distance between the first wire and a reference plane transverse to the longitudinal axis of the base roll sequentially increasing and decreasing at least once when moving in one direction about a circumference of the base roll.

Abstract: The invention comprises a flexible adsorbent-loaded filter formed from a flexible support web and attached adsorbent particles. The adsorbent-loaded filter has open filter cells which are defined by the support web and the attached adsorbent particles and are random in size and orientation through the length and depth of the filter. The support web is formed of substantially nonlinear filaments that randomly intersect. The adsorbent particles largest average cross sectional dimension is smaller than the average diameter of the pores of the support web. When the flexible adsorbent loaded filter is flexed about a radius of curvature 20 mm, the percent increase in pressure drop is less than 100 percent when measured at a face velocity of 0.25 m/s.

Abstract: A filtration system for filtering particulates from air. A plurality of point ionization sources are positioned in the proximity of the periphery of an air flow channel and being oriented to generate ions in the proximity of the air flow channel in a direction generally upstream from each respective one of the plurality of point ionization sources. A particulate collection surface is positioned within the air flow channel in a downstream direction from the plurality of point ionization sources. The particulate collection surface is electrostatically charged in an opposite direction with respect to ground than the electrical charge of the ions. An ion trap is positioned within the air flow channel between the plurality of ionization sources and the particulate collection surface. The ion trap is relatively electrically neutral as compared with the particulate collection surface and the ions.

Abstract: A filtration media array is provided having at least one contoured polymeric film layer having surface structures. The film layers may be configured as a stack that has the contoured film layer defining a plurality of ordered inlet openings through a face of the stack and corresponding air pathways, thereby forming an open, porous volume. The air pathways may be defined by a plurality of flow channels formed by the contours of the structured contoured film layers.

Abstract: A filter product includes a filtration media combined with a multi-component frame assembly that can effectively support the filtration media in place proximal to its edges and in accordance with its desired orientation and wherein the assembly can be selectively taken apart to provide access to the filtration media by way of a releasable lock connection. Preferably, a snap-fit releasable locking system is incorporated within the frame design. The present invention is particularly applicable to filtration media comprising pleated filtration media. Such support features include rack-like media engagement elements, which elements are advantageously provided so as to preferably engage the filtration media proximal to its side and end edges from above and below to preferably compress and ensure an effective seal and support connection between the frame and the filtration media.

Abstract: The present invention provides an adhesive closure tape tab (10,50) form of an elastic laminate (15) of an elastic film (16) having on at least a first major side an expandable fibrous layer (17) of non-woven thermoplastic polymer fibers. On the second major side of the plastic film are attached, a first (30) and a second (20) non-elastic adhesive tape. Each adhesive tape is formed of a fibrous layer (21) of non-woven thermoplastic polymer fibers having on one major surface an adhesive layer (22). The first (30) and second (20) non-elastic adhesive tape are attached opposite to each other to the second major side of the elastic laminate (15) by an adhesive layer (22) and extending beyond the elastic laminate (15).

Abstract: There is provided an improved tab member for a closure system comprising a tab portion and a slot member. The slot member includes a slit or a loop, with the slot located between an inboard portion and an outboard portion. The tab portion has a tab member having a length, an inner edge, an outer edge and at least one lip portion. The tab member outer edge is passed through the slot of the slot member to engage the fastening device. Once passed through the slot, at least one lip portion of the tab member overlaps or catches the outboard portion of the slot member to prevent the tab member from disengaging from the slot member. The slot member outward portion is retained between the lip portion(s) and the underlying generally flexible tab carrier substrate.
