Appl. No.:

6/938657

Inventors:

Daryl L. Myers - Lawrenceville GA

Assignee:

American Telephone and Telegraph Company - AT&T Technologies, Inc. - Berkeley Heights NJ

International Classification:

B65H 67056

US Classification:

242 18A

Abstract:

Methods of and apparatus are provided for winding strand such as optical ers on alternate spools and for storing and protecting from damage coiled end portions of the strand to be wound on the spools in which the coils are clamped laterally of the coils with forces applied parallel to the axis of the coils. The methods and apparatus of the invention may be used for urging portions of the strand being fed to the spools and associated strand storage and clamping devices against the peripheral surfaces thereof to aid in the transfer of the distribution of the strand from one spool to the other spool.

International Classification:

H01B 1314

US Classification:

156 51

Abstract:

A conductive element is covered with an insulating material which is cooled within a predetermined temperature range, and preferably near or at ambient, by moving the conductor first through a cooling trough and then in a plurality of convolutions about spaced grooveless rollers which comprise a capstan. The length of the cooling trough is such that the insulation is not deformed as it engages the capstan and the number of convolutions wrapped about the capstan which is subjected to a cooling medium are determined to insure that the temperature of the conductor exiting from the capstan is at or near ambient. Unlike conventional grooved capstans, the capability of the grooveless capstan to provide for a variable number of convolutions compensates for temperature differences caused by different conductor designs and/or manufacturing parameters such as line speed and thereby insures that coaxial capacitance measurements taken at the exit end of the capstan are made with the conductor temperature being substantially constant.

International Classification:

US Classification:

24211841

Abstract:

A spool (20) which is used in the taking up and the paying out of a relatively long length of optical fiber includes two flanges (24, 26) and a hub (22) with each flange being tapered. The spool includes a collector (30) which is formed adjacent to one of the two tapered flanges of the spool and which provides access to the initial or leading end portion of the length of optical fiber which is wound on the spool. A groove (32) of the collector communicates with the hub of the spool through each of the two diametrically opposed slots (28--28) in the adjacent tapered flange (24). This allows the optical fiber to be wound on one of two coaxially mounted spools and to be transferred to the other spool with the first few convolutions being received in the groove and then passed through one of the slots in the adjacent tapered flange onto the hub. In order to prevent losses in the optical fiber portion (44) which extends through one of the slots, each slot is sufficiently wide to avoid unduly sharp curvature of the optical fiber portion. The spool with outwardly sloped flanges provides for a stable winding pattern which prevent snags in pay out operations.

US Classification:

Abstract:

In taking up drawn lightguide fiber (31), the fiber is distributed on the hub of one of two coaxially mounted takeup spools 42-42 which are driven independently of each other at ends of indexable turrets (94-94) that also have spools mounted on their opposite ends. Following takeup on one of the spools, a distributor 201 effects a cutover to a collector groove of the adjacent spool until several convolutions of the fiber are secured within the collector groove to provide access to a leading end of the fiber on this spool for testing purposes. Then the distributor begins its traverse across the hub of the empty spool and the lightguide fiber which extends across the adjacent collector spools is severed to form an end portion on the spool now being filled, said end portion advantageously being accessible for testing. The full spool is caused to be moved out of its takeup position and another empty spool is moved into that position to be filled after takeup has been completed on the spool in the other takeup position.

International Classification:

US Classification:

425113

Abstract:

Flow conditions in an extrusion head in a cross head type extrusion apparatus for applying a concentric plastic insulating covering uniformly around a longitudinally advancing filamentary core advancing axially through a die concentrically disposed in an extrusion chamber in the head, are improved by providing channeled tooling within the chamber which bends and divides an initial stream of plastic material forced into the chamber into a plurality of equal streams which combine symmetrically around the core. With respect to certain channels, the ratio of the length of the channel to its effective cross-sectional diameter exceeds a predetermined critical number to achieve the development of steady state fluid flow therein. Additionally, whenever a stream of plastic material is divided subsequent to a bend before steady flow can develop therein, the division is made symmetrically with respect to the principal plane of the preceding bend to ensure identical pressure and velocity profiles in each of the divided streams.

International Classification:

US Classification:

219 1049R

Abstract:

An induction furnace (60) for reflowing a portion of an optical preform (12) in order to draw a lightguide fiber (11) therefrom includes a tubular susceptor (80) which is disposed centrally within a beaker (75) and a sleeve (82) which is disposed concentrically about the susceptor. The sleeve is spaced from the susceptor and is surrounded by insulating grain (83). A high frequency coil (84) is energized to couple its electromagnetic field to the susceptor to heat and reflow a portion of the preform. The movement of contaminating particles of the insulating grain into the interior of the susceptor is prevented substantially by annular, felt-like discs (91, 105) at the bottom and top of the beaker. The discs collect particulates which move downwardly and upwardly and because of their compliant engagement with the beaker and with the sleeve, they provide seals at those interfaces. The discs also are effective to prevent inadvertent lateral movement of the sleeve to maintain the concentricity of the sleeve and the susceptor.

International Classification:

C03B 37025

US Classification:

65 2

Abstract:

A system (20) for providing clean air to an apparatus (24) for drawing lightguide fiber (21) from a preform (22) includes a plenum (52) and ducts through which room air is pulled and filtered. The filtered air is flowed into each of a plurality of stacked enclosures (66, 67, and 68) each of which surrounds partially the drawing apparatus and portions of the preform and/or fiber. Also, the filtered air is directed transversely past the fiber and preform at a velocity which is sufficiently low to avoid undue flutter of the fiber. Filters are arranged in ascending magnitude of efficiency proceeding from an intake (41) for the room air to the vicinity of the preform and fiber. A delivery system which is associated with each drawing apparatus is considerably less expensive than a clean room and allows maintenance of any one system or its associated drawing apparatus without discontinuing the drawing operation of other systems in the same room.

Abstract:

A technique for dynamically transferring a lightguide fiber (10) from a full spool (18) to an empty spool (19) as both spools rotate at the same velocity and the input velocity of the fiber is constant. The lightguide fiber (10) is wound onto the rotating spool (18) in such a manner as to form a package of wound material having a conically tapered section (52) when full. The fiber (10) is then wound along the tapered section (52) as the velocity of the spools (18 and 19) are increased. When the fiber (10) is at the diameter of the tapered section (52) which is equal to the diameter of the empty spool, it is transferred to the empty spool without any substantial loss of fiber spooling control.
