The improved mold assembly for cultured marble molding is provided. The mold assembly can comprise a male mold portion and a female mold portion. The assembly can further comprise a molding tool. The molding tool can have a side wall having an upper curved s and a lower curved portion. The molding tool can be constructed from a flexible and/or soft material. The lower curved portion of the molding tool can be coated with a gel coat having a first color. The molding tool can facilitate molding of a countertop having a recessed bowl portion having a color different from a counter portion of the countertop.

A mold for a wire grid polarizer includes a hard mold and a soft mold, in which the hard mold includes a main body, an oxidization layer provided on the main body, and a SAM layer provided on the oxidization layer and including an additive, the soft mold includes a substrate, and a protrusions and depressions portion including a polymerized releasing agent, and a region that is hydrophobic in the polymerized releasing agent is arranged on a surface of the protrusions and depressions portion.

A carbon filter is disclosed. Such a carbon filter includes a carbon-based core having a central cavity, a layer of a polymer-based filter material surrounding the carbon-based core, and at least one end cap fixedly attached to the carbon-based core.

An automotive assembly comprises a sheet molding composite (SMC) element comprising an SMC sheet body shaped into a generally smooth functional section and at least one generally planar bonding section. The bonding section comprises a textured surface impressed as a result of molding the SMC sheet body in a compression molding tool having a corresponding textured pattern. The textured surface has a predetermined surface roughness for increasing the effective surface area of the bonding section relative to a non-textured surface. The predetermined surface roughness is in a range from 0.25 R.sub.a (m) to 8.5 R.sub.a (m). A second element has a secondary bonding surface adjoining the bonding section of the SMC element. An adhesive joins the secondary bonding surface to the bonding section without requiring any pre-treatment of the bonding section.

A method of producing a cellular structure via an additive manufacturing technique includes the steps of: providing a feedstock material to an additive manufacturing printer device; dispensing the feedstock material from the printer device; and controlling the dispensing of the feedstock material to form at least one layer of the cellular structure according to a first predetermined gradient. In some aspects, the cellular structure comprises an array of cells surrounded, respectively, by walls, and arranged to create a non-uniform relative density and/or cell geometry across a width and/or a height of the cellular structure. An article of manufacture produced by such methods includes a cellular structure configured to produce a controlled collapse with selectable dynamic stiffness characteristics by altering the distribution and geometry of cells within the cellular structure, while being able to maintain a substantially similar static stiffness characteristic.

Sound-attenuating mufflers and muffler inserts, and systems and uses of such mufflers and muffler inserts. Continuous fiberglass roving is fed to a pneumatic jet head which fluffs the roving and presents the fluffed roving to a delivery wand at the exit end of the jet head. The delivery wand is moved along a predetermined three-dimensional path such that the wand delivery tip travels along a predetermined three-dimensional path inside a mold while-depositing fluffed fiberglass strands into the mold along the predetermined path. A terminal end portion of a liquid resin conduit is mounted to the fiberglass-dispensing wand, as part of the delivery tip, and drip-feeds liquid resin onto the fiberglass as the fiberglass is being deposited in the mold. The undulating, up and down movement of the delivery tip produces a wave-like undulating pattern in the appearance of the rovings in the resulting molded product.

Problem To suppress the distribution of adsorption materials and binders between a heat-transfer member and a heat-transfer member from being disproportioned.

SOLUTION TO PROBLEM There is provided a method for preparinq an adsorption device in which activated carbons are held in an area of accommodating a plurality of heat-transfer members 34 arranged by intervals with each other in a main body part 31. The method includes a filling step (step 102) for filling a slurry filler 45, in which porous particles 41 and binder resins 42 are dispersed in a solvent 46, into the area , to fill the filler 45 into at least a clearance S between the heat-transfer member 34 and the heat-transfer member 34, an evaporating step (step 103) for heating the main body part 31 in which the filler 45 is filled in the area in a first-temperature range to evaporate the solvent 46, and a hardening step (step 104) for heating the main body part 31 in which the solvent 46 is evaporated in the evaporating step (step 103) in a second temperature range higher than the first temperature range to harden the binder resins 42.

Material processing systems are disclosed. Some systems include methods of eliminating or reducing defects in elongate workpieces that can undergo large deformations during processing. Some systems include apparatus configured to facilitate such large deformations while maintaining internal stresses (e.g., tensile stresses) below a threshold stress. Some disclosed systems pertain to powder extrusion techniques. Continuous and batch processing systems are disclosed.

A turbine component patch delivery system can include a compressed gas source fluidly connected to a delivery line comprising a dispensing end. The turbine component patch delivery system can further include one or more turbine component patch carriers that can be projected out of the dispensing end of the delivery line by the compressed gas source, wherein each of the one or more turbine component patch carriers comprise a turbine component patch material housed within a breakaway shell.
