Patent number: 5776251Abstract: In a duplex type coating apparatus, a left-right pair of dies and are disposed on opposite sides of a carrying path of a web, the dies and are each made up of an upper member and a lower member, a tip part of the lower member projects further toward the carrying path than a tip part of the upper member, and coating liquid discharge passages are inclined in the direction of the carrying path of the web. As a result, because the same amount of coating liquid is discharged from each of the dies and coated onto each side of the web, it is possible to carry out coating at the same coating thickness and in the same position on both sides of the web.Type: GrantFiled: September 30, 1996Date of Patent: July 7, 1998Assignee: Hirano Tecseed Co., Ltd.Inventors: Nobuaki Irie, Takao Ishida, Akiyoshi Hashimoto, Yasutomi Yoshimura

Patent number: 5772765Abstract: The flat workpieces (W) are conveyed in the vertical position on a horizontal transport path through at least one processing cell (BZ) that contains a processing bath, vertical slots (S) for the passage of the workpieces (W) being provided in the end walls of the processing cell (BZ). Bars or rods which are arranged in pairs in the processing bath, such that they are loose in the vertical direction, are assigned in pairs to the slots (S) as seals (D) and are pressed by the liquid pressure against one another or against the workpiece (W) respectively passing through, and against the assigned end wall of the processing cell (BZ). Seals (D) having a circuilar cylindrical cross section rotate while the workpieces (W) are passing through. The seals (D) are preferably arranged in end chambers (SK) which are fitted at the ends to the processing cells.Type: GrantFiled: November 12, 1996Date of Patent: June 30, 1998Assignee: Siemens S.A.Inventor: Daniel Hosten

Patent number: 5763003Abstract: A method and apparatus for covering a ribbon of optical fibers with a resin. The resin is polymerizable under the effect of UV radiation and forms a protective covering surrounding and holding the fibers. The method includes a pre-polymerization step during which the coated fibers advance through a UV irradiating chamber having a pre-polymerization ultraviolet radiation power of less than one fourth of the total power required to polymerize the resin, which is just sufficient to initiation polymerization. This step is followed by a polymerization finishing step during which the pre-polymerized ribbon is subjected to UV radiation of higher power than the radiation produced during the pre-polymerization step, which completes the polymerization process.Type: GrantFiled: September 29, 1995Date of Patent: June 9, 1998Assignee: Alcatel CableInventors: Jean-Pierre Bonicel, David Keller, Christopher Mc Nutt

Patent number: 5744194Abstract: A process for coating at least one optical waveguide with a filling compound has at least two successive filling stages separated by a wiping device of reduced cross section. In the region of the wiping device, a proportion of the filling compound which is thus wiped off is led past the wiping device by a bypass and is fed once more to coat the optical waveguide in the second filling stage.Type: GrantFiled: June 21, 1996Date of Patent: April 28, 1998Assignee: Siemens AktiengesellschaftInventors: Thomas Muller, Frank Renner, Wilfried Reissenweber, Reiner Schneider

Patent number: 5736001Abstract: A combination drywall joint compound hopper and drywall tape dispenser is disclosed having an open topped basin affixed atop said a flat stabilized base. The basin is for storing drywall joint compound, and a tape holder is mounted adjacent to and aligned with the basin. A first pinch roller extending laterally across the top of the basin, and a second pinch roller extends laterally across and within the basin aligned in a parallel manner with said first pinch roller across and near the open top of the basin such as to form a separation gap between the outermost edges of the pinch rollers of approximately 1/8 inch, for allowing for passage of a section of drywall tape between said two pinch rollers while as the same time acting as a scraper to govern the amount of joint compound which adheres to the surface of the drywall tape.Type: GrantFiled: April 10, 1996Date of Patent: April 7, 1998Inventor: Jeffrey C. Samuelson

Patent number: 5736199Abstract: A system of gating orifices for continuous pressure infiltration processes eliminates blow-out of the pressurized molten metal matrix material and friction damage to the infiltrated preform. The system includes three or more orifices along a vertical path of an upwardly moving preform which passes from vacuum or atmospheric pressure into a pressurized infiltrating bath of molten metal, then into a pressurized atmosphere in which the matrix fully solidifies, and from there to an atmospheric environment. The entering orifice, at the bottom of the pressurized bath, is elongated in the direction of the preform movement to provide a temperature gradient from above the matrix material melting temperature at the bath to below the solidification temperature farthest from the bath. The resulting liquid-mushy-solid sequence of the matrix material forms a solidification seal to prevent blow out of the pressurized molten metal.Type: GrantFiled: December 5, 1996Date of Patent: April 7, 1998Assignee: Northeastern UniversityInventor: Joseph T. Blucher

Patent number: 5733607Abstract: A method and apparatus for coating and curing fiberglass sleeving with an ultraviolet light curable acrylic includes the steps of singeing the fiberglass sleeve at a singeing station and thereafter, cooling the sleeve. The fiberglass sleeve is then coated with an ultraviolet light curable acrylic resin. Thereafter, the coated fiberglass sleeve is cured by passing it through a curing station wherein the sleeve is subjected to ultraviolet light radiation about its entire circumference. The process is speed adjustable and further, the intensity of the light emitted from the ultraviolet light source may be varied so that the system is tuned to cure fiberglass sleeves of any diameter up to approximately 1.00 inch.Type: GrantFiled: January 28, 1997Date of Patent: March 31, 1998Inventors: Rufus M. Mangum, Elliott S. Faircloth, Tony Maurice Moore

Patent number: 5718765Abstract: This continuous galvanizing method and apparatus passes a linear element to be galvanized, e.g., wire, rod, or tube, through a surrounding, relatively short length of conduit which is attached as a cross-tee to the end of a delivery pipe rising from a centrifugal pump submerged in a vat of molten zinc, and continuously flooded with liquid zinc to coat the linear element. The zinc flowing from the open ends of the conduit, and falling as excess from the element being coated, drops back into the vat for recirculation. The vat is covered to provide a substantially closed operating space above the pool of molten zinc to enable the coating to take place in an inert atmosphere.Type: GrantFiled: February 29, 1996Date of Patent: February 17, 1998Assignee: Allied Tube & Conduit CorporationInventors: Carl H. Unger, Kalyan K. Maitra

Patent number: 5709910Abstract: A system for applying textile treatment compositions to textile materials. A conduit member is provided which includes a passageway having a first end, a second end, and a medial portion with a constricted (narrowed) region. The passageway may include at least one baffle having an opening therethrough. A yarn strand is then moved through the passageway. A textile treatment composition (a sizing agent or dye) dissolved in a carrier medium (a supercritical fluid or liquified gas) is thereafter introduced into the constricted region, preferably at an acute angle relative to the passageway. The carrier medium expands inside the passageway which causes delivery of the treatment composition to the yarn. The treated yarn then passes through the baffle (if used) which facilitates drying of the yarn. During this process, a carrier gas can be introduced into the passageway to ensure the production of a smooth, dry product.Type: GrantFiled: November 6, 1995Date of Patent: January 20, 1998Assignee: Lockheed Idaho Technologies CompanyInventors: Mark D. Argyle, William Alan Propp
