Abstract: The present invention is directed to extrusion dies for making extruded synthetic wood and methods relating thereto. The dies include adapter dies, transition dies, stranding dies, and molding dies. The adapter dies include a channel with a restricted cross-sectional area. The stranding dies include a plurality of non-uniform channels that differ in length, cross-sectional area, cross-sectional shape, or combinations thereof.

Particular configurations of dies upstream of the molding die allow for higher compression ratios in the molding die than previously feasible. Each of the dies described herein may be used individually with standard dies known in the art. Alternatively, the dies may be used in combination to form integrated units. The dies described herein allow for making stronger, more consistent synthetic wood at greater output rates than previously possible.

Abstract: A mold for imprinting a patterned region by imprint lithography is provided with a peripheral groove around the patterned region. The groove is connected, as by channels through the mold, to a switchable source for gas removal to prevent bubbles and for the application of pressurized gas to separate the mold and substrate. In use, the mold is disposed adjacent the moldable surface and gas is withdrawn from the patterned region through the groove as the mold is pressed toward and into the moldable surface. At or near the end of the imprinting, the process is switched from removal of gas to the application of pressurized gas. The pressurized gas passes through the groove and separates or facilitates separation of the mold and the moldable surface.

Each of the plural electrodes includes a current collector, and an electrode layer, formed on the current collector, which contains an active material. The configuration of the electrode layer (for example, the amount of the active material) varies according to the position in the electrode layer such that a current density in a first region of the electrode, where heat radiation performance is lower than the heat radiation performance in a second region of the electrode, is lower than the current density in the second region of the electrode.

Abstract: A method for forming temporary protective coatings and bondable surfaces is disclosed. In the method, a soluble layer is disposed on a material surface, such as the interior surfaces of cell walls of a web material. The soluble material is then removed or leached from the web material to form and expose a roughly textured, bondable surface for bonding with another material, such as AVCOAT insulation. Use of the soluble layer, therefore, enhances the bondability of any surface that requires good adhesion, such as where the surface is difficult to reach for conventional surface preparation techniques.
