A method of manufacturing a flow field plate includes mixing graphite and resin materials to provide a mixture. The mixture is formed into a continuous flow field plate, for example, by ram extrusion or one or more press belts. The continuous flow field plate is separated into discrete flow field plates. Flow field channels are provided in one of the continuous flow field plate and the discrete flow field plates.

Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary additive manufacturing method may include forming a part using additive manufacturing. The method may also include bringing the part to a first temperature, measuring the part along at least three axes at the first temperature, bringing the part to a second temperature, different than the first temperature, and measuring the part along the at least three axes at the second temperature. The method may further include comparing the size of the part at the first and second temperatures to calculate a coefficient of thermal expansion, generating a tool path that compensates for the coefficient of thermal expansion, bringing the part to the first temperature, and trimming the part while the part is at the first temperature using the tool path.

Methods for manufacturing topsheets for absorbent articles are disclosed. The methods may include: providing a cycling forming belt that includes an air-permeable substrate and an ordered arrangement of airflow blocking structures thereon; directing air flow with entrained fibers and/or filaments to a working location through which the belt cycles; drawing the air flow through airflow permeable regions of the belt as they cycle through the working location, and thereby drawing the fibers/filaments to the belt such that they accumulate thereon to form a batt having an arrangement of built-up regions and attenuated regions corresponding with the arrangement of blocking structures, wherein the structures are arranged in individualized single-topsheet configurations that repeat along the machine direction, each configuration being adapted to form a section of web material for a topsheet and to impart a desired formation thereto including channel portions, hinge portions and/or pattern(s) of discrete low bulk portions.

What is presented is a unit cell comprising a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry arranged to have a coincident central vertex. The cubic cell geometry comprises three orthogonal cell faces that intersect at its central vertex. The tetrahedral cell geometry comprises an arrangement of eight tetrahedral cells that share its central vertex such that each tetrahedral cell shares three coincident edges with three other tetrahedral cells in a cubically symmetric arrangement. The tetrahedral cell geometry is combined with the cubic cell geometry such that all vertices of the tetrahedral cell geometry are coincident with the vertices of the cubic cell geometry.

Methods of making a male touch fastener product, by shearing distal portions of loops extending from a side of a flexible fabric, leaving fibers extending from the side of the flexible fabric in place of the sheared loops, the fibers extending to respective free distal ends, while leaving other loops extending from the side of the fabric intact, and then heating the distal ends with energy supplied by a linear energy source, such that resin of the distal ends flows to form enlarged heads on the extending fibers, while leaving at least some of the other loops intact. A male touch fastener product has a flexible fabric base with a broad side, and fibers extending from the broad side of the base. The fibers form both loops of fibers, each loop extending from the base at two spaced-apart points, and fiber segments extending from the base to respective distal fiber ends spaced from the base. Each distal fiber end forms an enlarged head of fiber resin for snagging other fibers.

A consumable material for use in an extrusion-based digital manufacturing system, the consumable material comprising a length and a cross-sectional profile of at least a portion of the length that is axially asymmetric. The cross-sectional profile is configured to provide a response time with a non-cylindrical liquefier of the extrusion-based digital manufacturing system that is faster than a response time achievable with a cylindrical filament in a cylindrical liquefier for a same thermally limited, maximum volumetric flow rate.

A method of manufacturing an imprint master template including forming a cutting line guide at an edge of a first fine pattern unit having an upper surface on which a fine pattern is formed; cutting a wafer substrate by a cleaving process along the cutting line guide so that a cutting surface is formed, the cutting surface having a preliminary second surface where the cutting line guide was formed and a first surface which is formed by the cleaving process; polishing the preliminary second surface to form a second surface which is inclined at a predetermined angle with respect to the first surface; and bonding the first fine pattern unit and the second fine pattern unit to each other with the first surface of the first fine pattern unit facing the first surface of the second fine pattern unit.

An edible orally disintegrating tablet dosage form containing an unpalatable acidic active pharmaceutical ingredient, particularly ketoprofen, and an ion exchange resin as a primary taste masking agent, along with an optional alkaline agent and further optionally containing one or more secondary taste masking agents is provided. The edible orally disintegrating tablet dosage matrix is formed from at least one water soluble or miscible polymer(s). The optional secondary taste masking ingredients include one or more of flavoring agent(s), sweetener(s), cooling sensation agent(s), and taste receptor blocker(s). The inventive dosages minimize or completely mask the bitterness, burning sensation and throat irritation associated with many acidic active pharmaceutical ingredients. Methods for preparing the inventive edible oral film strip dosage forms are disclosed, as well as their method of administration.

An encapsulation cover for an electronic package includes a cover body having a frontal wall provided with at least one optical element allowing light to pass through. The optical element is inserted into the encapsulation cover by overmolding into a through-passage of the frontal wall. A front face of the optical element is set back with respect to a front face of the frontal wall. The process for fabricating the encapsulation cover includes forming a stack of a sacrificial spacer on top of an optical element, with the stack placed into a cavity of a mold.

A method for fabricating a multi-color cellulose acetate spectacle frame, which includes: baking a multi-color cellulose acetate sheet so that it is soften; pressing so as to enable the second, third, and fourth color layers of the multi-color cellulose acetate sheet to move a distance greater than the thickness of a surface color layer of the multi-color cellulose acetate sheet; grinding off or shaving off a surface layer of the excessively moved portion so that the color of a middle layer is highlighted; baking the multi-color cellulose acetate sheet again so that it is soften; pressing so that the color of the middle layer is highlighted to the surface of the spectacle frame. According to the method for fabricating the multi-color cellulose acetate spectacle frame, the working processes are saved, and the qualification rate of product is improved.
