A multi-laminar electrospun nanofiber scaffold for use in repairing a defect in a tissue substrate is provided. The scaffold includes a first layer formed by a first plurality of electrospun polymeric fibers, and a second layer formed by a second plurality of electrospun polymeric fibers. The second layer is combined with the first layer. A first portion of the scaffold includes a higher density of fibers than a second portion of the scaffold, and the first portion has a higher tensile strength than the second portion. The scaffold is configured to degrade via hydrolysis after at least one of a predetermined time or an environmental condition. The scaffold is configured to be applied to the tissue substrate containing the defect, and is sufficiently flexible to facilitate application of the scaffold to uneven surfaces of the tissue substrate, and to enable movement of the scaffold by the tissue substrate.

Disclosed are an entrained polymer or an entrained polymer composition, and a method for forming and adhering an entrained polymer structure to a substrate using the entrained polymer or an entrained polymer composition. The method includes providing a substrate configured to receive application of a molten entrained polymer. A particulate entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least abase polymer and a particulate active agent. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer.

A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.

A plastic preform includes a hollow body portion including a closed base portion and a lower portion and a lower portion extending upwardly from the closed bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening positioned at a top of the neck portion, threads positioned below the dispensing opening, a tamper-evident formation having a lower surface and positioned directly below the threads, and a support flange having an upper surface and a lower surface and positioned below the tamper-evident formation. In an embodiment, the plastic preform is formed of a material comprising polyethylene terephthalate (PET), and a vertical distance from the lower surface of the tamper-evident formation to the lower surface of the support flange is from 0.125 to 0.150 inches. Containers and methods for molding preforms and making containers are also disclosed.

A pelletizing apparatus includes a filter device connected with a melt feed, a granulator downstream of the filter device, particularly an underwater granulator, a water treatment device, and a control means for controlling the filter device, underwater granulator, and water treatment device and adapted to provide at least one control parameter. The apparatus includes at least one machine-readable and -writable identification means for storing and providing an item of component-specific information and being associated with a component in the flow path of the melt or the process water, and a reading device communicating with the control means to receive the component-specific information from the identification means, and a writing device to write the identification means with the component-specific information, the control means to adapt the control parameter based on the component-specific information to provide the component-specific information, and, based on the component-specific information, to execute a diagnostic process.

This disclosure relates to air-assisted spinnerets and spinneret arrays for electrospinning. In some embodiments, the air-assisted spinnerets and spinneret arrays are incorporated in electrospinning systems and/or electrospinning machines. Methods of making and using the same are also described herein.

Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.

Provided are a liquid crystal polymer film including a liquid crystal polymer, in which a melting point is 315° C. or higher and a number-average molecular weight is 13,000 or more and 150,000 or less; a flexible copper-clad laminated board; and a manufacturing method of a liquid crystal polymer film.

A washing machine includes a casing, a tub, a drum, a circulation pump, an annular gasket connecting between openings of the casing and the tub and including circulation nozzles configured to supply water into the drum, and a conduit fixed to the gasket and guiding water to the circulation nozzles. The conduit includes an inlet port configured to receive water from the pump, a transport pipe configured to guide water from the inlet port to the circulation nozzles, and a supply ports configured to supply water to the circulation nozzles. A method for manufacturing a conduit includes positioning supply ports in a cavity defined at a first mold, forming a parison having a hollow opening by extruding a raw material, positioning the parison in the cavity, combining the first mold and a second mold, and injecting gas into the hollow opening of the parison.
