Provided are an apparatus and methods for dispensing a composition, the apparatus includes a barrel () having an inlet () and an outlet (), a screw () received in the barrel, and a drive mechanism operatively coupled to a shank end () of the screw to rotate the screw. The screw is hollow and includes both interior and exterior surfaces, the interior surfaces defining a cavity () adjacent to the outlet, and wherein the screw further includes a plurality of apertures () through which the cavity and exterior surfaces communicate with each other. The apertures are located along a perforated portion () 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 () having a raised flight section () and one or more lowered flight sections (), where the apertures are at least partially located on the lowered flight section.

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.

An article for dissipating accumulated static charges from a substantially insulated surface. The article includes a single layer elongate conductor, having opposing ends, and at least one fastener located to join the opposing ends together to provide a continuous conductive loop in contact with the substantially insulated surface. The fastener further provides electrical connection to a ground cord for removal of accumulated static charge from the substantially insulated surface. A fastener may be either electrically conductive or electrically insulating provided it facilitates contact between the elongate conductor and a conductive portion of a ground cord.
