Patent Number Title Of Patent Date Issued
5922141 Method for non-contact fiber cleaning July 13, 1999
A method of cleaning fiber of dust and particulate matter thereon includes the steps of directing the fiber passage having an entrance end and an exit end; protecting the fiber from abrasion at the entrance end and the exit end; passing the fiber through a vacuum chamber in the fiber pas
5634236 Non-contact fiber cleaning and tensioning device June 3, 1997
A noncontact fiber cleaning and tensioning device for cleaning optical fibers of dust and other particulate matter collected thereon. The noncontact fiber cleaning and tensioning device includes a housing formed from a cleaning and an exhaust section and includes a fiber passage formed
5558287 Apparatus and method to prevent flailing damage to a strand wound on a spool September 24, 1996
An apparatus and method for reducing or preventing damage to a strand wound at relatively high speed on a machine-rotated spool, caused by flailing of a loose end of the strand includes capture brushes arranged at intervals in proximity to the machine. The capture brushes are aligned to
5277730 Methods of recoating spliced lengths of optical fibers January 11, 1994
Spliced end portions (30--30) of two optical fibers are recoated in a manner which results in the cross section of the spliced length of fiber transverse to a longitudinal axis thereof being substantially constant. This is accomplished without compromising the adhesion of a curable r
5261023 Stable package of elongated optical fiber strand material November 9, 1993
An optical fiber package of this invention applies a friction enhancing material to the smooth surface of a bobbin or mandrel onto which the optical fiber is wound. The friction enhancing material adheres the initial layer of fiber to the smooth surface of the bobbin, thereby elimina
5257339 Package of optical fiber suitable for high speed payout October 26, 1993
An optical fiber package (15) includes a support surface such as a hub of a bobbin (17) for convolutions of a length of optical fiber. The optical fiber includes a light transmitting portion such as a core and a cladding with inner and outer layers of coating material disposed thereabout
5205890 Method for providing stable package of elongated optical fiber with bonded convolutions April 27, 1993
An optical fiber package (52) includes a length of optical fiber (22) wound in a plurality of convolutions on a bobbin (50). In order to maintain the convolutions in a precision wound package and to prevent snags during payout, it is necessary that each convolution of optical fiber be ad
5033389 System for guiding a vehicle from a rest position to a target July 23, 1991
An optical fiber package (52) includes a length of optical fiber (22) wound in a plurality of convolutions on a bobbin (50). In order to maintain the convolutions in a precision wound package and to prevent snags during payout, it is necessary that each convolution of optical fiber be ad
4976596 Apparatus for recoating spliced lengths of optical fibers December 11, 1990
Spliced end portions (30--30) of two optical fibers are recoated in a manner which results in the cross section of the spliced length of fiber transverse to a longitudinal axis thereof being substantially constant. This is accomplished without compromising the adhesion of a curable r
4950049 Stable package of elongated optical fiber strand material August 21, 1990
An optical fiber package (52) includes a length of optical fiber (22) wound in a plurality of convolutions on a bobbin (50). In order to maintain the convolutions in a precision wound package and to prevent snags during payout, it is necessary that each convolution of optical fiber be ad
4865411 Recoated spliced lengths of optical fibers September 12, 1989
Spliced end portions (30-30) of two optical fibers are recoated in a manner hich results in the cross section of the spliced length of fiber transverse to a longitudinal axis thereof being substantially constant. This is accomplished without compromising the adhesion of a curable recoatin
4510348 Non-shielded, fire-resistant plenum cable April 9, 1985
A relatively small pair size cable (20) comprising at least one insulated conductor (22) is provided with a flame retardant, smoke suppressive non-metallic sheath system (30). The sheath system has a relatively low thermal conductivity and provides a predetermined delay prior to the
4319940 Methods of making cable having superior resistance to flame spread and smoke evolution March 16, 1982
A method of making a cable (20) specially suited for use in building plenums because of its low flame spread and smoke evolution includes enclosing a multiconductor core (22) in a sheath comprising an inorganic, cellular core wrap (31), a corrugated metallic barrier (40) and dual lay
4284842 Cable having superior resistance to flame spread and smoke evolution August 18, 1981
A cable (20) specially suited for use in building plenums because of its low flame spread and smoke evolution includes a multiconductor core (22) which is enclosed in a sheath comprising an inorganic, cellular core wrap (31), a corrugated metallic barrier (40) and dual layers (51) and (5
