Abstract: Apparatus for treating filamentary products, such as yarn, includes advancing the yarn in a groove, which has orifices opening in the bottom thereof, and which communicate with a channel through which a fluid is expelled. The channel lies in the wall of a cylindrical static body and is tangent to the inner wall of said body. The fluid supports the strand so that the yarn does not touch the groove. In addition, the fluid treats the yarn and helps to advance the yarn.

Abstract: Apparatus for applying preparation agents onto a large filament bundle passing through substantially vertically, comprising an applicator head with a slit for applying the preparation agent and at least one guide edge for guiding the filament bundle. A supply duct supplies the preparation agent to the slit. The applicator head consists of at least two opposite surfaces forming the slit and the guide edge, which surfaces are provided at least in the slit with a roughness assisting the distribution of the agent in the slit.

Abstract: The production of organic fibers with inorganic cores is set forth. Inorganic, such as glass, fibers are attenuated from a bushing and then covered individually or in small groups with organic sheaths. With individual fibers, rows or orifices in a bottom of the bushing are staggered so as to equally space the filaments. The applicator for applying the organic sheaths has one groove for each of the individual fibers for applying the organic material and for maintaining the fibers separated therebelow. The applicator can be mounted in a manner such that it can be retracted from an operating position in engagement with the filaments when the bushing operation is stopped, raised to a position near the bushing bottom, and moved into engagement with the fibers again to automatically place one fiber in each groove when the bushing is restarted. The applicator is then moved down to the operating position again when the bushing is back in normal operation.

Abstract: A high-strength parallel yarn rope comprises a series of multi-filament rope yarns which are bounded together in parallel relation along their lengths by a binder distributed only on the surfaces of the yarns to form a flexible rope core. The core is surrounded by a braided jacket, and a flexible layer of water-impervious material adhesively and mechanically bonds the core to the jacket.A method is also disclosed for manufacturing the rope.

Abstract: A web dispenser wherein an elongated coated web is dispensed from a container by manually pulling the same through a closely confined rotatable ball closure whereby the coating is metered.

Abstract: A very-fine microcircuit interconnecting wire is passed through a central ifice in a capillary bonding head of a thermo-compression device which is used for pressing the balled end, or the body, of the microcircuit interconnecting wire to the metallized pads of a hybrid circuit chip. A pair of capillary tubes are moveably attached to the capillary bonding head in such a way that they can be positioned with their orifices opposing each other on opposite sides of the very fine wire just below the central orifice of the capillary bonding head. An insulating adhesive or enamel is passed through the capillary tubes to blend around the wire and form an insulating layer as the capillary bonding head is moved from one bonding point to the next.

Abstract: A coating material applicator is provided which applies a coating material to fibers, more specifically filaments, in a uniform manner. The applicator, which has no moving parts, directs the coating material in a tortuous path from a supply inlet to a filament-coating bar which applies the coating material to the filaments passing thereby. The tortuous path preferably has at least one inverted U-shaped portion which helps separate air trapped in the coating material. The applicator preferably has at least three chambers with the coating material passing down through the first chamber, up through the second, and down through the third from which it exits to the coating bar. Fibrous material can be located in the first chamber, and also in the second, if desired, to help separate and collect the air from the coating material. A vent also can be located in the first chamber and in the second, too, particularly if that chamber also has fibrous material therein, to vent the air periodically.

Abstract: Application of a graphite film to at least the first roll contacted by a metal strip to which a coating metal has been applied. The roll may be scraped clean and the graphite film applied immediately after scraping. The graphite film may be applied by wiping the roll with a solid graphite block or by wiping the roll with a graphite colloidal suspension in a suitable carrier. In the latter event, the roll temperature must be high enough to vaporize the carrier so that strip contamination is avoided. The graphite film prevents adherence of coating metal particles to the roll surface whereby damage to the coated surface on the metal strip is prevented.

Abstract: A yarn in the form of a supply package in which the yarn is wound on a bobbin is continuously washed with an aqueous washing liquid by standing the yarn supply package upright in means for receiving the yarn package and an aqueous washing liquid, and continuously drawing off the yarn upward from the package while bringing the aqueous washing liquid into contact with the outer surface of the package. The contact of the outer surface of the package with the washing liquid is effected by immersing the package in the washing liquid bath or by flowing the washing liquid down over the outer surface of the package.

Abstract: The invention relates to a machine for cooling metal wire. This machine comprises a cooling tube, an injection device for the cooling fluid and a bypass device for the cooling fluid. The injection device comprises an oblique annular slot fed under high pressure and injectors fed under low pressure. The bypass device comprises an open elbow extending the tube and a second elbow of an opposite curvature terminating in a direction normal in relation to that of the wire. The invention is applied to the cooling of a metal wire, with or without hardening.

Abstract: This is an apparatus for continuously applying a reinforced insulated coating to a conductor. The apparatus includes a die which provides means of directing a first coating, a reinforced fabric and a second coating to the conductor continuously in the proper sequence.

Abstract: A method and apparatus for galvanizing an elongated conductive metal element by drawing it through a bath of molten zinc in a conductive pan. Corrosion of the pan is prevented by electrically isolating the element from the pan, except through the zinc, eliminating circulating currents between the element and the pan wall. Quality of the coating, and particularly the uniformity of the thickness of the zinc deposited on the element, is improved by stabilizing the electrical potential in the element and thus the current flowing longitudinally through it. Where multiple elements are drawn in parallel through the bath for simultaneous galvanizing, circulating currents between them are minimized by electrically short circuiting the elements at the incoming and exit ends of the bath.

Abstract: A process for controlling the amount of polymer applied to a lace in which a powdered heat is applied to melt the polymer and the composite is passed through a die to consolidate the product and remove excess polymer, the control being effected by detecting the amount of excess molten polymer and automatically adjusting the polymer input. The process is also suitable for controlling the amount of polymer applied in a process for coating a lace.
