METHODS FOR MANUFACTURING BULKED CONTINUOUS FILAMENT
A method of manufacturing bulked continuous carpet filament, in various embodiments, comprises: (A) providing an expanded surface area extruder; (B) providing a spinning machine having an inlet that is operatively coupled to an expanded surface area extruder outlet; (C) using a pressure regulation system to reduce the pressure within the expanded surface area extruder; (D) passing a plurality of flakes comprising recycled PET through the expanded surface area extruder to at least partially melt the plurality of flakes to form a polymer melt; and (E) substantially immediately after passing the plurality of flakes through the expanded surface area extruder, using the spinning machine to form the polymer melt into bulked continuous carpet filament. In some embodiments, the method may include passing the plurality of flakes comprising recycled PET through a PET crystallizer prior to extrusion.
Reinforced coreless tube extrusion systems and methods
Methods of coating a base tube are disclosed. Various methods include passing a hollow base tube into a coating die while maintaining a chamber pressure outside the hollow base tube that is lower than a pressure within an inner lumen of the hollow base tube. Such methods can include extruding coating material onto the hollow base tube to form a coated hollow tube by delivering coating material into the coating die. Vacuum may be formed within the coating die proximate a point of impingement where the coating material is applied to the hollow base tube.

Seals and method for making same
Extruded seals including a sealing portion with a honeycomb profile and method for making extruded seals with honeycomb profiles. An extrusion tool is provided with a first and second plate connected together. The first plate has a plurality of pins, which are vented to form a honeycomb profile. The second plate has a profiled opening receiving the plurality of pins and forming the overall shape of the part, including the outermost surfaces of the part. The pins serve as mandrels for extruded molten material to flow around. Varying the pin configuration and dimensions changes the honeycomb profile. The honeycomb structure is provided in the sealing portion of the extrusion. The honeycomb profile is formed by itself, co-extruded with a rigid or semi-rigid structural member, or applied to the rigid or semi-rigid structural member after the structural member is formed.
Formation of three dimentional objects including magnetic material
Implementations described herein are directed to forming objects including one or more layers of a polymeric material that include a magnetic material. The objects can be produced by forming one or more first layers that include a first polymeric material. The one or more first layers can be free of a magnetic material. Additionally, the object can be produced by forming one or more second layers that include a second polymeric material having a magnetic material. For example, the one or more second layers can include a polymeric material embedded with magnetic particles. The one or more first layers and the one or more second layers can be formed by extruding the first polymeric material and the second polymeric material onto a substrate according to a pattern. A magnetizing device can be used to magnetize the magnetic material included in the one or more second layers.
ABUSE-PROOFED DOSAGE FORM
The invention relates to a dosage form that is thermoformed without discoloration and is safeguarded from abuse, comprising at least one synthetic or natural polymer having a breaking strength of at least 500 N in addition to one or more active substances that could be subject to abuse. The invention also relates to a corresponding method for producing said dosage form.

BIOMEDICAL PATCHES WITH ALIGNED FIBERS
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.
