The present invention relates to a liquid, thermoplastic acrylic gel cap composition that can impart UV resistance, higher impact, and aesthetic effects to a composite material. Additionally, the post processing of the material when combined with a thermoplastic composite can allow for thermoformability, weldability and recyclability, unlike seen with traditional thermoset based gel coats.

A system for pressing one or more stacks of one or more laminae (22), the system comprising: a tool including top (14b) and bottom plates (14a) configured to be disposed on opposing sides of each of one or more stacks (22) of one or more laminae, each of the plates (14a, 14b) having: a center region that overlies or underlies the stack(s) (22) when the stack(s) are disposed between the plates (14a, 14b); and tabs (174) that extend outwardly from edges of the center region and are configured to be coupled to a conveyor or one or more grippers for moving the plate; and a resilient layer (90) configured to be disposed between the top plate and the stack(s) (22) or the bottom plate (14a) and the stack(s) (22); wherein the resilient layer (90) is sized to be disposable between the plates such that, for each of the plates (14a, 14b): the resilient layer (90) overlies or underlies at least 90% of the center region; one or more portions of the resilient layer (90) neither overlie nor underlie the plate; and at least a portion of each of the tabs neither overlies nor underlies the resilient layer ((14a, 14b)). Also claimed is a method for producing laminates by pressing.

The mounting portion, having a helical length, for removably attaching the blade segment. The vane portion extending from the mounting portion along the helical length thereof. The vane portion having a front surface that is not parallel to a back surface from the mounting portion to a tip of the blade segment, along the helical length.

A process for the production of a coated rubber item, comprising: (i) provision of a semifinished product having the main shape of the rubber item, where the semifinished product is composed of a rubber composition comprising at least one rubber and at least one crosslinking agent; (ii) coating of the semifinished product with a solvent-free coating composition comprising at least one monomer amenable to free-radical polymerization, (iii) crosslinking of the rubber composition and polymerization of the coating composition, to give a coated rubber item;
wherein the boiling point of the at least one monomer amenable to free-radical polymerization is ≥150° C. and the crosslinking of the rubber composition takes place at the same time as the polymerization of the coating composition.

In a preferred embodiment, a composite panel with a smooth outer surface, ready for painting with or without addition of primer, may be created by constructing a panel layup assembly upon a mold, the panel layup assembly including a composite panel having a core and a resin formulation, and a release film between the mold and the composite panel, where a smooth release surface of the release film is in contact with the composite panel upon construction; initiating curing of the composite panel at a first temperature within a lowermost ten percent of a curing temperature range of the resin formulation; continuing curing of the composite panel at a second temperature above the lowermost ten percent of the curing temperature range; and completing curing of the composite panel at a third temperature below the second temperature.

Provided is a method of manufacturing a sensor. The sensor has a casing having an opening portion, a clamp having a recessed part on its outer periphery and having one end inserted into the opening portion, and a sealing ring attached to the recessed part and disposed between the casing and the clamp. The method includes using a first divided mold to form a first component of the clamp, the first component including a main body portion and a first part located at one end side of the main body portion and forming a part of the recessed part. The first divided mold is divided so that a dividing surface intersects the main body portion and separates in an axial direction of the main body portion.

An imprint apparatus forms a pattern of an imprint material in a shot area of the substrate using the mold, and includes a heating mechanism that changes a shape of the substrate by irradiating the shot area of the substrate with light, wherein the heating mechanism includes a plurality of optical modulators that forms an illuminance distribution in the shot area of the substrate, and light beams from the plurality of optical modulators illuminate mutually different areas of the shot area.

According to one embodiment, a template for imprint patterning processes comprises a template substrate having a first surface and a pedestal on the first surface of the template substrate, the pedestal having a second surface spaced from the first surface in a first direction perpendicular to the first surface. A pattern is disposed on the second surface. The pedestal has a sidewall between the first surface and the second surface that is at an angle of less than 90° to the second surface.

Some embodiments of the invention provide methods that can create large area complex patterns for nanoimprint molds without or with very litter of the use of the charged beam or photon beam direct-writing of nanostructures. Some embodiments of the invention use (i) Fourier nanoimprint patterning (FNP), (ii) edge-guided nanopatterning (EGN), and (iii) nanostructure self-perfection, and their combinations.

A method of forming a container (1) and a container (1) formed thereby. A preform (2), having a generally cylindrical body (60, 8) extending between a closed end (12) and an open mouth, is placed within a mold (20, 22) having surfaces corresponding in shape to the desired container (1). An incompressible medium, which is the end product that remains in the molded container (1), is injected under pressure into the preform (2). Under the influence of the incompressible medium, the preform (2) is expanded into contact with the surfaces defining the cavity, simultaneously forming and filling the container (1). During expanding of the preform (2), portions of the plastic material are forced into a series of recesses (72) defined in the cavity surface (82, 85). With the incompressible medium contained therein, the container (1) is removed from the mold (20, 22) and including a series of raised dots corresponding to the series of recesses (72) defined in the cavity surface (82, 85).
