An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

Disclosed herein is an injection molding method for making optical thermoplastic lenses using 3D-printed functional wafers. The wafer and base lens are made of different materials having dissimilar glass transition temperatures.

Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.

A reinforced composite assembly includes a first sheet made of carbon fiber and having a first perimeter, a second sheet made of a non-carbon fiber material and having a second perimeter, wherein the second sheet is disposed atop the first sheet within the first perimeter, and a metallic plate having a third perimeter, wherein the metallic plate is disposed atop the second sheet within the second perimeter. The metallic plate has a plurality of holes formed therein about a perimeter of the metallic plate and defining a plurality of respective bridge portions between each of the holes and an adjacent outer edge of the metallic plate, and/or a plurality of extensions extending outward from a main portion of the metallic plate. A first arrangement of thread stitching secures each of the bridge portions and extensions to the second sheet or to the first and second sheets.

A solid nano- or micro-structured thermoplastic foil including a nano- or micro-structured surface area is produced by providing an extrusion casting roller for an industrial polymer extrusion casting process using a thermoplastic material, applying a nano- or micro-structured surface on the extrusion casting roller, maintaining a temperature of the casting roller below a solidification temperature of the thermoplastic material while the casting roller and the counter roller are rotating, and continuously applying a melt of the thermoplastic material between a counter roller and the casting roller while the casting roller and the counter roller are rotating. A rotational velocity of the casting roller may be 10 meters/minute. The melt of the thermoplastic material is moved between the casting roller and the counter roller while the rollers are rolling, and the melt of the thermoplastic material is solidified upon contact with the casting roller to form the thermoplastic foil.

A fiber optic cable includes a cable core of core elements and a protective sheath surrounding the core elements, an armor surrounding the cable core, the armor comprising a single overlap portion when the fiber optic cable is viewed in cross-section, and a jacket surrounding the armor, the jacket having at least two longitudinal discontinuities extruded therein. A method of accessing the cable core without the use of ripcords includes removing a portion of the armor in an access section by pulling the armor away from the cable core so that an overlap portion separates around the cable core as it is being pulled past the cable core. A protective sheath protects the core elements as the armor is being pulled around the cable core.

Packages used to deliver items or other payloads via a drone may be customized and 3D printed to house the payload. The package may be customized to minimize the size and/or weight needed to house the payload. The customized packages may include one or more attachment mechanisms adapted to engage with or otherwise be coupled to the drone for delivery. Multiple individual customized packages can be secured together into a composite package for delivery by drone. The customized package may be designed to be aerodynamic given the shape of the payload and the flight characteristics of the drone. The drone itself may be the package, with the payload housed within a portion of the drone. The package and/or a portion of the drone (e.g., fuselage, wing, body, frame, etc.) may be printed at least partially in, on, or around an item or package to be transported by the drone.

The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.

A method for manufacturing an integrated hull by using 3D structure type fiber clothes and 3D vacuum infusion process includes: sequentially stacking at least one first fiber cloth, at least one core material and at least one second fiber cloth on a mold; deploying structural materials on the second fiber cloth; stacking the third fiber clothes to cover the structure materials and a part of the second fiber cloth, whereby the first fiber cloth, the core material, the second fiber cloth and the third fiber clothes are formed to a lamination; determining a pipe arrangement of vacuum pipes and first and second resin pipes; deploying a vacuum bag on the lamination and covering the first and second resin pipes and the vacuum pipe; executing the 3D vacuum infusion process; curing the resin; and executing a mold release process to complete an integrated hull.

An injection mold including a gate and a cavity, where a weld portion is formed inside the cavity by injecting molten resin containing reinforcing fibers from the gate into the cavity, the injection mold has a resin reservoir open to the cavity, and in a first cross section along an opening end surface 110S of the resin reservoir 110 to the cavity, a distance CLD between a width center line CL11 of the resin reservoir and a width center line of the cavity, which is measured along a perpendicular line n12 of the width center line CL12 of the cavity, changes at least in part along the width center line of the cavity.
