Abstract: Methods and apparatuses for roll coating are provided. The roll coating system (100) includes a coating roll (110) having a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14), the inner layer being softer than the outer layer. A substrate (3) is conveyed to the nip (12) between the coating roll and a back-up roll (120). A metered coating material is transferred from the coating roll to a patterned surface structure (40) of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

Abstract: A stretchable conductor includes a substrate with a first major surface, wherein the substrate is an elastomeric material. An elongate wire is on the first major surface of the substrate; the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Composite articles including a stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

Abstract: Methods and apparatuses for screen or stencil printing a pattern on a substrate are provided. The substrate (2) has its major surface in contact with a first major surface (112) of a stencil shell (111) having apertures (116). A coating material is disposed onto the second major surface (114) of the stencil shell (111) to flow through the apertures (116) to contact the substrate (2), where the coating material is at least partially cured. The substrate (2) is separated (C) from the first major surface (112) of the stencil shell (111) after the curing (142) and a pattern (42) of the at-least-partially-cured coating material is formed on the substrate (2).

Abstract: An abrasive article comprises a porous substrate having openings extending through the porous substrate between first and second opposed major surfaces. An abrasive coating is disposed on only a portion of a first major surface of the porous substrate. The abrasive coating comprises a functional layer disposed on only a portion of a first major surface of the porous substrate, a make layer disposed on at least a portion of the functional layer opposite the porous substrate, and abrasive particles. The functional layer and the make layer independently comprise chemically crosslinked binders. The functional layer fully occludes a first portion the openings and does not fully occlude a second portion of the openings, which permits passage of abraded swarf through the abrasive article. Methods of making the abrasive article are also disclosed.

Abstract: Diagnostic devices for quantitative or qualitative analysis of a sample fluid including an analyte include at least two portions made from a hydrophilic material. The planar portions are stacked on each other and each occupy a different and substantially parallel plane to form a three-dimensional structure. At least one of the planar portions includes a hydrophobic region formed by applying a low surface energy material that extends through a thickness of the substrate portion from a first major surface to a second major surface thereof. The hydrophilic regions in the overlying substantially parallel substrate portions can be aligned with each other such that a fluid is passively transported between adjacent hydrophilic regions to provide a sample flow path between adjacent substrate portions.

Abstract: A diagnostic device includes a sensor stack with multiple panels of a porous material disposed in planes parallel to one another and in face-to-face contact with each other. At least a portion of the panels of the porous material include hydrophobic regions and hydrophilic regions configured to provide a sample flow path for migration of a fluid sample through the sensor stack from one panel to another in the hydrophilic regions. A wicking layer is on a major surface of the sensor stack.
