  • Patent number: 10618008
    Abstract: A separation membrane for selectively separating (e.g., pervaporating) a first fluid (e.g., a first liquid) from a mixture comprising the first fluid (e.g., first liquid) and a second fluid (e.g., second liquid), wherein the separation membrane includes a polymeric ionomer that has a highly fluorinated backbone and recurring pendant groups according to the following formula (Formula I): —O—Rf—[—SO2—N?(Z+)—SO2—R—]m—[SO2]n-Q wherein: Rf is a perfluorinated organic linking group; R is an organic linking group; Z+ is H+, a monovalent cation, or a multivalent cation; Q is H, F, —NH2, —NH2, —O?Y+, or —CxF2x+1; Y+ is H+, a monovalent cation, or a multivalent cation; x=1 to 4; m=0 to 6; and n=0 or 1; with the proviso that at least one of morn must be non-zero.

  • Patent number: 9470127
    Abstract: A structure comprising at least one inorganic layer comprising inorganic materials suitable for use in a pollution control device. A friction-inducing material is disposed on at least one side of the inorganic layer. The deposited friction-inducing material defines a higher friction area exhibiting a static coefficient of friction higher than that of the inorganic materials. A lower friction layer is disposed so as to cover at least a portion of the higher friction area and define an exposed surface area of the structure. The exposed surface area exhibits a lower static coefficient of friction than that of the higher friction area. The lower friction layer no longer covers a substantial portion of the higher friction area, after the pollution control device is assembled.

  • Patent number: 9238981
    Abstract: A mounting mat (16) comprising at least one inorganic layer (18) comprising inorganic materials suitable for mounting a pollution control element in a pollution control device. A friction-inducing material (20) is disposed on at least one side of the inorganic layer (18). The deposited friction-inducing material (20) defines a higher friction area exhibiting a static coefficient of friction higher than that of the inorganic materials. A lower friction layer (20) is disposed so as to cover at least a portion of the higher friction area and define an exposed surface area of the mounting mat (16). The exposed surface area exhibits a lower static coefficient of friction than that of the higher friction area. The lower friction layer (20) no longer covers a substantial portion of the higher friction area, after the mounting mat (16) mounts a pollution control element (14) in a pollution control device (10).

  • Patent number: 7972670
    Abstract: A structured paper release liner (10) for use with an article (44) backed with a pressure sensitive adhesive, an adhesive-backed article assembly (42) and methods of making each are disclosed. The liner (10) comprises a piece of paper (14) having a release side free of a structural support layer, a back side, and a structured release surface (48) having a pattern formed into the paper (14) on the release side. A release material is on the structured release surface of the paper. The pattern formed in the paper (14) is designed so as to form fluid egress channels in a bonding surface of the pressure sensitive adhesive (46). The fluid egress channels define a structured bonding surface (48) having exit pathways for fluid to bleed out from behind the article when the structured bonding surface (48) is adhered to or otherwise disposed on a substrate.

  • Patent number: 6524681
    Abstract: A friction material for a friction facing member useful for transmitting torque includes a backing having a front surface and a rear surface. A plurality of precisely shaped friction composites defining patterned friction coating are attached to the front surface of the backing. The precisely shaped friction composites include a plurality of friction particles dispersed in a binder. In one embodiment, the friction material has an elastic modulus of about 107 dynes/cm2 or less.
