摘要： A polymerizing fluid polymer (thermoplastic, elastomer, thermoset polymer, thermoplastic elastomer, thermoplastic vulcanizate) with an optional filler (such as magnetizable ferrite powder or carbon nanotubes) is extruded or pultruded into shaped polymer (optionally multilayer shaped polymer) so that all portions of the shaped polymer conform within a desired state of polymerization (in a multilayer coating, that the quality-related performance characteristics of shaped polymer are consistent within any coating layer). At least one (tear-drop shaped) flow diverter is described for diverting flow within an extrusion (pultrusion) die so that fluid polymer moving through a short residence time portion of the die will have a more substantial residence time (than would be the case if the diverter were not used) with commensurately greater thermal, pressure, and shear stress history so that the desired conformance respective to polymerization states for all portions in the shaped polymer is achieved.

摘要： A polymer extrusion crosshead assembly for forming a spirally-striped extrusion. The assembly includes conventional components for admitting, turning, and accelerating primary molten polymer toward a novel rotating die sub-assembly. A body element includes an axial counterbore for receiving a manifold supply block in communication with a source of secondary striping polymer. A wear plate is attached to the manifold block. The die sub-assembly includes a striping die having an annular passage for conveying the primary polymer to form an extruded tube or a core material coating. The die is loaded against the wear plate by a Belleville washer. The die includes one or more striping nozzles in communication with the manifold block for injecting secondary striping polymer into the annular stream of primary polymer flowing through the die, creating a longitudinal stripe of striping polymer. Rotating the die while extruding both polymers yields a helically striped (spiral) extrusion.

摘要： An extruder apparatus and method for producing an extruded tubing having varying inner dimensions without changing the outer dimensions. The tubing is forced from the die face of an extrusion head having an extruder die and an internal mandrel determining the outer and inner dimensions, respectively, of the extruded tubing. The outer dimensions of the mandrel varied by the user to change the inner dimensions of the extruded tubing. A pressure is maintained in the extruded tubing to prevent its collapse and that pressure is changed based upon the change of the external dimensions of the mandrel and the wall thickness of the tubing. In one embodiment, the mandrel is comprised of a core and a plurality of telescoping sleeves. Each sleeve is movable between a retracted position where the sleeve is displaced away from the die face and an extended position where sleeve is at the die face. There may be multiple mandrels in the case of multi-lumen catheters.

摘要： A crosshead die for a plastic optical fiber fabrication system is provided. The crosshead die includes a body, an insert, mounting flanges on the upstream and downstream end for securing the crosshead die to adjacent equipment or another crosshead dies, an axial port for receiving a mixed molten material that makes up the core, and a radial port for receiving a mixed molten material that makes up the outer layering material to be co-extruded over the core. The die insert includes a material distribution channel system that provides substantially the same linear distance for the mixed molten material to travel prior to the co-extrusion. If multiple die inserts are utilized, the crosshead die is able to co-extrude multiple layers over the core. If the crosshead dies are serially assembled, additional concentric layers of material can be co-extruded atop the layered plastic optical fiber extruded from the upstream crosshead die.

An upper inner die member immediately above the lower inner die member has a substantially horizontal lower surface engaged with the substantially horizontal upper surface of the lower inner die member, the substantially horizontal lower surface having a second groove extending from the upper end of the first feed passage to the longitudinal axis and forming a second fed passage with the first groove. The upper inner die member has a third feed passage extending substantially vertically upwardly from the lower substantially horizontal surface thereof at the longitudinal axis and in communication with the second feed passage. At least one fourth feed passage in the upper inner die member extends from an upper end of the third feed passage to the helical passages between the upper and lower inner die members.

摘要： Method and apparatus for manufacturing a composite insulator which includes an FRP core rod covered by a sheath and provided with a plurality of sheds which are made of an electrically insulating polymeric material. The sheds are set on a support member arranged on a downstream side of an extruder. The extruder is fed with a core rod and extrudes a polymeric material to form a sheath on the core rod. The core rod with the sheath is moved toward the downstream side through an opening in the support member. The sheds are sequentially moved along the support member toward the downstream side and transferred onto predetermined locations on the sheath that have passed through the opening and have reached the downstream side. An assembly is thus formed which includes the core rod, sheath formed on the core rod, and sheds transferred onto the sheath. The assembly is then heated to vulcanize the sheath and adhere it to the core rod and the sheds.

摘要： A guiding catheter or angiographic catheter and method of manufacture for use in cardiovascular interventions which incorporates an annealed low-flexibility proximal zone wherein a transition zone separates the proximal zone and a high-flexibility distal zone. The catheter is subjected to a slicking operation to improve the smoothness of the high flexibility distal zone in order to better traverse the aortic arch shape while reducing excess energy storage. The proximal zone is annealed to provide a high level of stiffness for optimal support and pushability. A mid-region zone transitions the high stiffness of the proximal zone to the higher flexibility of the distal zone to eliminate buckling and kinking.

摘要： A method of making an enclosed, hollow insulating spacer for spacing apart panes of a multiple pane unit. The method includes steps of forming metal into first and second leg members for a spacer, preheating the first and second leg members of the spacer near the melting point of one of a synthetic resin material and a composite synthetic resin material, feeding the preheated first and second leg members of the spacer into a crosshead extruder together with one of the resin materials to embed by crosshead extrusion only a portion of each of the first and second leg members into the material, to affix the embedded portion of each of the leg members to the material and to form from the material a first bridge member that extends between the leg members and spans across one end of each of the leg members, and providing a second bridge member that connects the opposite ends of the leg members. Thereby defined is an enclosed channel portion of an insulating spacer, which has a hollow interior, by a configuration of the first bridge member, the first and second leg members and the second bridge member.
