    摘要： Provided are an apparatus and methods for dispensing a composition, the apparatus includes a barrel (120) having an inlet (128) and an outlet (129), a screw (122) received in the barrel, and a drive mechanism operatively coupled to a shank end (134) of the screw to rotate the screw. The screw is hollow and includes both interior and exterior surfaces, the interior surfaces defining a cavity (142) adjacent to the outlet, and wherein the screw further includes a plurality of apertures (140) through which the cavity and exterior surfaces communicate with each other. The apertures are located along a perforated portion (146) of the cavity, where the perforated portion can have a transverse dimension that increases with distance from the shank end. The apertures can also provide a hole area, relative to the exterior surface of the screw, that increases with distance from the shank end. The screw can also include a helical flight (132) having a raised flight section (150) and one or more lowered flight sections (152), where the apertures are at least partially located on the lowered flight section.

    摘要： Polymeric multilayer film having first and second generally opposed major surfaces, and comprising first, second, and third layers, an array of blind openings between the first and second major surfaces, and an average thickness, wherein the first, second, and third layers each have a first average thickness excluding any thickness said first, second, and third layers having in any of the blind openings, wherein the first and second layers extend into the first average thickness of the third layer, wherein each of the first, second, and third layers each have a second average thickness (including a thickness of zero) in the blind holes, wherein the second average thickness of the first and third layers are each greater than zero, and wherein the ratio of the first average thickness of the second layer to the second average thickness of the second layer is at least 2.1; and method of making the same. Embodiments of polymeric multilayer film described herein are useful, for example, for acoustic absorption.

    摘要： A curved display includes a display panel having a curved major surface and a light control film disposed proximate the display panel. The curved major surface is curved about a first axis, and a central portion of the curved major surface has a surface normal along a second axis substantially orthogonal to the first axis. The light control film includes a major surface having a substantially same shape as the curved major surface and includes a plurality of alternating optically transmissive and optically absorptive regions. In a cross-section orthogonal to the first axis, a transmissive region and adjacent absorptive regions define a central ray transmission direction through the optically transmissive region such that a light ray emitted by the display panel and transmitted through the optically transmissive region along the transmission direction is refracted upon exiting the curved display into a direction substantially parallel to the second axis.

    摘要： Coextruded polymeric layer having first and second opposed major surfaces, the coextruded polymeric layer comprising foam and the coextruded polymeric layer comprising features extending from or into the first major surface by at least 100 micrometers, the first major surface comprising a first material having a first percent elongation at break, the second major surface comprising a second material having a second percent elongation at break, wherein the first percent elongation at break is greater than 100 percent of the second percent elongation at break. Coextended polymeric layers described herein are useful, for example, in vibration damping applications (e.g., a vibration damping laminate comprising a kinetic spacer comprising the coextruded polymeric layers).

    摘要： A condensation management apparatus comprises a first microstructured film arranged to condense water vapor on a substantially vertical surface of a component. The first film comprises channels disposed on first and second major surfaces of the first film and dimensioned to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the first film. The longitudinal axis of the first film is tilted at a tilt angle of at least 4 degrees with respect to an axis normal to a direction of gravity. Openings in the channels are disposed at one or both end edges of the first film. The openings provide condensate release locations of the first film. A second film is disposed over a portion of the first film. The second film attaches the first film to the substantially vertical surface of the component.
