The invention provides an appartus for adjusting the thickness of a resin film exiting an extrusion lip of a blown film extruder, the apparatus comprising: a gear motor configured to provide a rotational movement in any one of two directions; an actuation unit connected with a first side to the gear motor and with a second side to the extrusion lip, wherein the actuation unit is configured to convert the rotational movement of the gear motor into an axial movement, and wherein the actuation unit is further configured to adjust a local width of the extrusion lip by the axial movement for adjusting the thickness of the resin film exiting the extrusion lip of the blown film extruder.

The present disclosure relates to an extrusion nozzle apparatus and a method for extruding a thermoelectric material using the extrusion nozzle apparatus. An extrusion nozzle apparatus according to one embodiment of the present disclosure comprises: an inlet introducing material; an outlet discharging the input material; and a discharge pipe formed in a multi-stage shape including a plurality of stages, wherein the input material is pressurized inside the discharge pipe and moves in a first direction from the inlet toward the outlet. The cross-sectional area of the plurality of stages in a direction perpendicular to the first direction progressively decreases from the inlet to the outlet. Accordingly, the thermoelectric performance of a thermoelectric material may be improved, and production cost and production time may be reduced.

Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

High Specific Mechanical Energy extruder screw assemblies (14, 88, 98) and complete extruders (10, 86, 96) are provided, which include wide-flight intermediate screw sections (104) having axial flight widths greater than the flight widths of the inlet and outlet screw sections (102, 106) on opposite sides of the intermediate sections (104). The intermediate sections (104) provide increased friction and shear serving to enhance the SMEs imparted to comestible food materials during processing thereof.

The invention relates to multilayer structures made of at least one thermoplastic material and having at least one metal layer. The invention further relates to multilayer products encompassing at least three layers comprising a substrate layer made of a substrate comprising specific copolycarbonates and at least one inorganic filler, a metal layer and one or more further layers. The invention further relates to the process for producing the said multilayer structures.

Disclosed herein is a die assembly comprising a first attachment block having a passage, an inlet port and an exit port; where the passage is operative to transport a molten material from the inlet port to the outlet port; a die; and a conduit; where the conduit comprises a passage that is operative to transport the molten material from the first attachment block to an entry port of the die; where the die comprises a first outer tube; and an extrusion pin that comprises a post and fins; where the extrusion pin is located in the first outer tube using the fins and where the post extends from the fins in a direction away from the entry port of the die; and where the post comprises one or more passages; where at least of these passages open to the atmosphere to provide for pressure equalization; and a travelling template; the template being operative to contact an extrudate that emanates from the die and to transfer a texture to a surface of the extrudate by virtue of pressure applied by a guide tube to the extrudate via the travelling template.

A ram extrusion apparatus including a die having several thermal zones, a hopper for introducing a granular polymer resin to the die, and a ram for moving the granular polymer resin through the thermal zones of the die and out from an outlet end thereof at a temperature above the crystalline melt temperature of the polymer resin. The hopper may be designed to deliver the polymer resin into a resin inlet of the die in a plurality of specifically metered amounts which may vary across a width of the resin inlet end of the die. The apparatus may further include one or more finishing tables positioned after the outlet end of the die for receiving and moving the extruded resin away from the outlet end of the die so that there is no backpressure on the extruded resin, and which provide compression force and even cooling to the extruded resin.
