Patent number: 5298105Abstract: An optical fiber stripper is formed with an interior cylindrical elongate passage for housing a fiber length and for containing stripper fluid. To assure ample room for expansion of the fiber coating during stripping, the passage has a greater volume than that of the coated fiber after the coating expands from contact with the fluid. The passage has a fluid inlet at its interior end for introducing stripping fluid. A relatively sharp shoulder disposed at the interior end of the passage and formed by a short cylindrical neck section coaxial with the passage has a diameter only marginally greater than the diameter of the coated fiber. Once the coating in the passage is softened by the stripper fluid, the fiber is withdrawn allowing the shoulder to cleanly strip away the coating. Advantageously, the stripper is made from graphite, so that any incidental contact with the fiber during the draw-stripping operation has no deleterious effect on the fiber surface.Type: GrantFiled: May 1, 1992Date of Patent: March 29, 1994Assignee: AT&T Bell LaboratoriesInventor: Carl S.

Patent number: 4774906Abstract: A continuously and synchronously operated plastics coating device for elongated bamboo poles or the like consists of a plastics feeding unit having a plastics injection unit planted in a perpendicular relationship to a molding member. Plastic is injected thereout in a film state through a round fissure so to coat a continuously forward-moving bamboo pole with a film of plastics. The pole is fed through one end of the assembly and moves into the film of plastics so that a continuous coating process is effected thereby.Type: GrantFiled: January 6, 1987Date of Patent: October 4, 1988Inventor: Fuh-Shyong Lu

Patent number: 4774904Abstract: Horizontal slider for the fabrication of semiconductor devices employs a succession of reservoirs and wells for successive applications of material in the growing of multiple layer semiconductor devices. The apparatus is composed of three assemblies each of which is fabricated of graphite to avoid contamination of the semiconductor material. The apparatus is operated within a furnace wherein the temperature is varied between a relatively high temperature for providing saturated solutions, to a lower temperature during which epitaxial growth can occur, and ambient temperature for completion of a fabrication procedure. One of the assemblies contains a set of wells, a second assembly contains reservoirs and slides horizontally upon the assembly of wells for alternately communicating reservoirs with wells and terminating such communication for a filling of the wells with requisite melts.Type: GrantFiled: September 29, 1986Date of Patent: October 4, 1988Inventor: Jamie Knapp

Patent number: 4671385Abstract: A device for being attached to the distal end of a cable assembly including a tube and an inner cable extending coaxially through the tube. The device includes a body located adjacent the distal end of the tube for receiving the distal end of the inner cable, includes structure for attaching the distal end of the inner cable to the body, includes a seal located between the body and the distal end of the tube for sealing the body to the distal end of the tube when the distal end of the inner cable is attached to the body and force is applied to the inner cable to pull the body against the distal end of the tube, and includes a grease fitting attached to the body for allowing grease to be forced therethrough into the interior of the tube to lubricate the inner cable when the body is sealed relative to the distal end of the tube.Type: GrantFiled: December 6, 1985Date of Patent: June 9, 1987Inventor: Calvin C. Travis

Patent number: 4624817Abstract: Disclosed is a coating die which has a dilatable orifice, the orifice being dilatable due to the use of a flexible, resilient portion of the die. The die is individually cast and is "strung-up" in the casting process. The preferred use for the die is in the coating of textile filaments, especially small diameter filaments that are slubby.Type: GrantFiled: May 18, 1984Date of Patent: November 25, 1986Assignee: Badische CorporationInventors: James A. Gusack, Thomas E. Smith

Patent number: 4622242Abstract: A variable-temperature pressure coating system for optical fibres, particularly for uv-curable primary coatings, includes a gas cylinder (8) for pressurizing a tank (1) of coating material, and a heat exchanger (15) controlling the temperature and thus the viscosity of the coating material supplied to a die chamber (19) through which an optical fibre (18) is passed following drawing. The temperature of the die chamber may also be controlled by the same circuit as the heat exchanger. A valve (14) serves to control flow to the die and to enable priming of the tube (13) by filling with coating material (and removal of air bubbles) prior to supply thereof to the die chamber (19). The system is designed for ease of operator handling together with production of high quality coatings at high speed.Type: GrantFiled: May 23, 1985Date of Patent: November 11, 1986Assignee: Standard Telephones and Cables Public Limited CompanyInventor: Malcolm D. Mackay

Patent number: 4608941Abstract: Apparatus for soldering printed circuit panels includes a roll configuration to convey the panels horizontally across a container carrying molten solder. The printed circuit panels are immersed in molten solder when they pass through the roll configuration. At least one air knife located at the output side of the roll configuration serves to level the molten solder on the panels as they exit from the rolls.Type: GrantFiled: January 10, 1985Date of Patent: September 2, 1986Assignee: Teledyne Electro-MechanismsInventor: Gilbert V. Morris

Patent number: H1350Abstract: The invention relates to coating devices and methods for application of sant to ammunition. Provided is a mechanically simple and effective way of weatherproofing or coating high volumes of small caliber sabot ammunition or similar items. The coating device typically consists of a container device, which is chamber of sufficient size and volume to hold sealant, covered by an integral lid comprising a frame holding a diaphram, sealant and means for applying the sealant. The frame and the diaphram are provided with aligning holes. The holes are sized to permit the object to be coated to penetrate through the frame, and deformably penetrate through the diaphram into the chamber and contacting the sealant and means of application. The means to apply the sealant may be a sealant dip, a series of spray jets to spray the sealant, a felt stamp pad, a fluidized bed, various combinations of these or any other type of application means to uniformly coat the object.Type: GrantFiled: October 28, 1992Date of Patent: September 6, 1994Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Anthony T.
