摘要:
An insulating flow block having a plurality of bores extending therethrough to permit the flow of molten fiberizable material through the block, a bushing assembly having a bushing block with one or more bores extending through a peripheral region thereof to divert a portion of a supply of molten fiberizable material from a central region of the bushing block to the peripheral region of the bushing block, and a bushing positioned in general registry with the bore of the peripheral region of the bushing block to facilitate the flow of molten fiberizable material to a peripheral region of the bushing is disclosed.
摘要:
A bushing including a tip plate having an orifice region including orifices to permit flow of a molten fiberizable material therethrough; a reservoir for supplying molten fiberizable material to the orifices; and a substantially planar perforated plate positioned within the reservoir generally parallel to and substantially coextensive with the orifice region of the tip plate, the perforated plate including a central region and a peripheral region surrounding the central region, each of the central region and the peripheral region of the perforated plate having a plurality of openings to permit flow of molten fiberizable material therethrough, wherein average head loss of molten material flowing through the central region of the perforated plate is greater than average head loss of molten material flowing through the peripheral region of the perforated plate.
摘要:
Cable arrangements include a length of springy cable looped in a figure 8 arrangement with an intermediate cross-over section between respective first and second looped sections of the cable. The figure 8 arrangement enables withdrawal of the cable from the arrangement with no more than a single twist of the cable to limit accumulated net linear twist of the cable while linearly extending the cable. The first and second looped sections may be positioned overlapping each other to provide a substantially toroidal shaped cable arrangement. An optical device may be provided on one or both of the ends of the length of cable. The springy cable may be a fiber optic cable, such as flat drop cable. Cable products, enclosures and methods of forming a cable arrangement are also provided.
