This disclosure provides a method for filling printing ink in an electrowetting display substrate and a method for producing the electrowetting display panel. The electrowetting display substrate comprises a first substrate. The first substrate has pixel grids formed by pixel walls. The method for filling printing ink in an electrowetting display substrate comprises steps of: filling a mixture of an oil-containing printing ink and a solvent into the pixel grids, wherein the solvent has a boiling temperature lower than that of the oil, and the printing ink is soluble in the solvent; and vaporizing the solvent at a temperature that is lower than the boiling temperature of the oil and higher than or equal to the boiling temperature of the solvent. The method may adjust the filling height of the printing ink effectively, and allow the filling heights of the printing ink in all pixel grids to be substantially the same, so as to enhance the display effect of the electrowetting display panel.

Some embodiments of the present disclosure relate to an apparatus including an additively manufactured node. The apparatus includes an additively manufactured interconnect co-printed with the node. The interconnect is configured to connect the node to a component.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.

A connection includes: a first profile having a first end, the first profile including a first polymeric material comprising a thermoset material; and a second profile having a second end, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end.

A method of manufacturing a composite part having a curved or radiused corner to avoid wrinkling or bridging of outer-most composite plies during consolidation and cure, including laying up composite material on male or female tooling to form two flanges extending at a first angle relative each other and a curved or radiused corner extending between the two flanges. Then the method may include changing an orientation of one or both of the flanges of the composite material, such that the two flanges extend at a second included angle relative each other. The second included angle is smaller than the first angle. The method may also include a step of consolidating the composite material before, after, or during the step of changing the orientation of the composite material to the second angle, as well as a step of curing the composite material oriented at the second angle.

A method and apparatus are disclosed. A method of printing onto a base includes providing a yarn from a material source disposed in a printing system. The yarn is an elongated continuous piece including a tagging segment and a reel segment. The reel segment is disposed proximate the material source. The tagging segment extends from a nozzle of the printing system. The method further includes attaching the tagging segment to the base and moving the nozzle away from the tagging segment after the attaching the tagging segment to the base. The nozzle is moved by an actuating system of the printing system. The moving the nozzle along the base increases a tension between the tagging segment and the material source. The tension in the yarn pulls the reel segment from the material source.

A cylindrical shrink label is provided with a heat-shrinkable label base material; and a joint formed by cylindrically forming the label base material so that the edges thereof overlap, and then solvent welding the inner surface of the outside edge, which is positioned on the outside of the cylinder, and the outer surface of the inside edge, which is positioned on the inside of the cylinder. A resin layer, which is soluble in a hot alkaline aqueous solution, is formed on the abovementioned inner surface and/or the abovementioned outer surface, which form the joint.

A repair apparatus is configured to repair a hole in a curved wall portion of a material guide. The repair apparatus includes a patch body that can conform to the shape of the curved wall portion and a retainer that non-destructively holds the patch body in place on the wall portion over the hole. In certain embodiments, the retainers are magnets or straps. The patch body can be flexible so that it can be adjusted to conform to the shape of curved wall portions of various sizes and curvatures. The patch body can include a wear-resistant inner surface. In some embodiments, the patch body includes an outer shell and a wear-resistant inner liner connected to the shell. The liner can have one side that is unattached to the shell.

The present disclosure provides a chemical container and a method for manufacturing the same. The chemical container comprises a head portion having a top wall and a head sidewall extending from an edge of the top wall, as well as a body portion jointed with the head portion and defining a chamber together with the head portion. The top wall has a mouth structure configured for one or more pipelines to pass through and connect with the chamber. The manufacturing method is simple and of low cost, and the resulted chemical container is able to withstand a greater internal pressure and is configured to collect any leaking liquid chemicals.

An apparatus for attaching a label to a moving cable, the apparatus comprising: a roller for pressing a label against the moving cable, wherein the label has a first attaching edge and a second attaching edge and wherein the roller comprises: a first roller for pressing the label against the moving cable, wherein the label is pressed against the moving cable with the first attaching edge and the second attaching edge of the label on opposites sides of the moving cable; a first roll down roller for folding the second edge of the label against the moving cable; and a second roll down roller for folding the first edge of the label against the moving cable.
