Extruded seals including a sealing portion with a honeycomb profile and method for making extruded seals with honeycomb profiles. An extrusion tool is provided with a first and second plate connected together. The first plate has a plurality of pins, which are vented to form a honeycomb profile. The second plate has a profiled opening receiving the plurality of pins and forming the overall shape of the part, including the outermost surfaces of the part. The pins serve as mandrels for extruded molten material to flow around. Varying the pin configuration and dimensions changes the honeycomb profile. The honeycomb structure is provided in the sealing portion of the extrusion. The honeycomb profile is formed by itself, co-extruded with a rigid or semi-rigid structural member, or applied to the rigid or semi-rigid structural member after the structural member is formed.

An additive manufacturing device for manufacturing a mould. The additive manufacturing device includes a container for providing at least one mould material, a build platform having a build surface for holding and/or supporting at least one mould being or having been manufactured by an additive manufacturing process, a source for providing energy to selectively activate and subsequently solidify the at least one mould material in or from the container to enable additive manufacturing of the mould, and an electronic controller adapted to selectively control the source to manufacture the mould as a one-piece sacrificial mould according to a predetermined design producing a one-piece additively manufactured mould.

Systems and methods are provided for divergent laminates. A method comprises providing a layup tool having a first upper face and a second upper face that rise to intersect each other at a ridge line, the layup tool further having a protrusion on top of a portion of the ridge line, and laying up a laminate onto the upper faces and the protrusion. The method also comprises placing a cure tool on top of the layup tool, the cure tool having a lower face that is dimensioned to mate with the upper faces along a portion of the ridge line that is not covered by the protrusion, thereby leaving a divergent flange of the laminate on top of the protrusion exposed, and sweeping the divergent flange of the laminate upward from the layup tool onto a vertical side the cure tool.

A method for designing a mould (120) for casting a semi-finished ophthalmic lens blank, wherein the surface of the mould (120) is designed so that the surface of the mould fits a predetermined closed curve, wherein the predetermined closed curve is representative of the geometry of a gasket (160) to be used in association with the mould (10). A method for assembling a mould assembly (100) and a method for casting a semi-finished ophthalmic lens blank, and a computer program product including software code portions for performing steps of these methods are also described.

A method for forming a high temperature field joint between two insulated pipe sections, and an insulated conduit having a low temperature field joint. The conduit comprises a steel pipe with a corrosion protection coating and a pipe insulation layer comprising a polymer composition having thermal conductivity of less than about 0.40 W/mk, and/or heat resistance to continuous operating temperatures from about 150° C. to above about 205° C. After a circumferential weld joint is formed between the two pipes, a first field joint insulation layer is applied over the joint area, the first field joint insulation layer comprises a polymer composition having heat resistance to continuous operating temperatures from about 150° C. to above about 205° C.

A template for imprint lithography can include a body. The body can include a base surface and have a recession extending from the base surface lying along a base plane, the recession including a main portion having a tapered sidewall. In a particular embodiment, the recession includes an intermediate portion having an intermediate sidewall. The intermediate sidewall is rounded or at least part of the intermediate sidewall lies at a different angle as compared to an average tapered angle of the main portion. In another aspect, a method of fabricating a semiconductor device can include forming a patterned resist layer having a tapered sidewall over a substrate having device layers; patterning the device layers using the patterned resist layer; and etching portions of at least some of device layers to expose lateral portions of the at least some device layers. The template is well suited for forming 3D memory arrays.
