Abstract: A self-supporting, pleated filter, and method of making the same. The method includes forming a plurality of pleats in a filter media that extend along a front face and a rear face. The pleats include a plurality of pleat tips and sloping side surfaces generally perpendicular to the direction of pleating. At least one planar reinforcing strip oriented in the direction of pleating is bonded to the pleat tips on the front face. At least one reinforcing member is positioned along the rear face of the filter media. The filter media is then cut to size. Frame members are applied for some applications. The reinforcing member may be a reinforcing strip oriented in the direction of pleating and bonded to the rear face of the filter media prior to the step of forming the plurality of pleats. A second planar reinforcing strip may optionally be bonded to the reinforcing strip pleat tips. The reinforcing member, the first reinforcing strip and the second reinforcing strip can be aligned to form a truss structure.

Abstract: A transparent optical film made of a polymeric material has a first smooth surface and a second structured surface for providing a simulated beveled appearance. The structured surface of the film is formed of a plurality of spaced parallel grooves, each groove being formed by a first facet which is substantially perpendicular to the first smooth surface and a second facet which makes an angle between 1 to 60 degrees with the first smooth surface. The film may be affixed to glass, the adhesive applied to the first smooth surface or the second structured surface, to simulate beveled glass. Further, a leaded glass appearance or beveled mirror appearance may be simulated by vapor coating the optical film.

Abstract: Known laminates can be used to apply graphics to glass panels to present an etched or sand-blasted appearance. Such graphics, which have been cut from a decorative polymeric film of a laminate, can be applied more easily, quickly, and with greater precision when the cover sheet of the laminate is a vented transparent polymeric sheet which bears a layer of vented removable pressure-sensitive adhesive that has been pressed against the graphics. Coextensive with each of the graphics is a layer of aggressive pressure-sensitive adhesive by which the graphics can be applied to a glass panel while wet with a detergent/alcohol/water solution that permits them to be repositioned by a user who can see the graphics through the vented transparent sheet. Positioning is enhanced when the vents are perforations arranged in an orderly pattern such as a rectangular grid.

Abstract: An appliqu e adapted to be adhered for decorative purposes to a planar surface on a layer of transparent material (e.g., of glass or plastic). The appliqu e comprises a layer of polymeric material which is transparent and free of visible inclusions. The front surface of that layer includes a planar central portion having a decorative surface texture (e.g., the surface texture of rippled glass, hammered glass, moss glass, Flemish glass, glue chip glass, or baroque glass), and beveled surface portions around that textured surface portion.

Abstract: Filtration material comprising a web comprising meltblown fibers and staple, electrically charged fibers randomly dispersed among the meltblown fibers. The filtration material can be formed in planar configurations and in configurations other than planar. Non-planar configurations can extend the useful working area for a given filter element's cross-section without requiring an additional corrugating or pleating process step. The filtration material exhibits high strength and low pressure drop.

Abstract: A twisted sewing thread comprising at least two strands made of ceramic fibers at least one of which strands is served with organic or inorganic fibers, the strands being individually twisted or two or more strands twisted together in one direction and then an assembly of the resulting twisted strands plied with other like or different twisted strands in the opposite direction to produce the ceramic fiber sewing thread.
