Publication number: 20040144057Abstract: A framing system for buildings that includes a plurality of studs and track mounted together to form a unique framing system. Each stud defines a longitudinally extending body, opposing foldable end flaps, and opposing flanges that extend outwardly from the body. Each of the opposing flanges also includes a second flange that extends outwardly from the opposing flanges at approximately an angle of ninety degrees. Mounted to the plurality of studs is the plurality of track. Each of the plurality of track defines a longitudinally extending track body and opposing track flanges extending outwardly from the track body.Type: ApplicationFiled: October 10, 2003Publication date: July 29, 2004Applicant: Allied Tube & Conduit CorporationInventors: Michael Alan Meek, David Donald Plueard

Patent number: 6197394Abstract: A tube product and improvement in the production of coating tubing, as most preferred, includes hot dip galvanize zinc coating of tubing, and before solidification of the zinc coating, clear coating of the tubing with organic polymer coating. The heat of the hot dip cures the clear coating, and the clear coating preserves a consistency and reflectivity of the zinc previously unseen in finished products. In additional preferred embodiments, organic polymer coatings are applied to zinc coated and uncoated tubing, and the organic polymer coatings are applied by electrostatic powder coating.Type: GrantFiled: June 7, 1995Date of Patent: March 6, 2001Assignee: Allied Tube & Conduit CorporationInventors: Edward E.

Patent number: 5855674Abstract: A method and apparatus for continuous galvanizing of a linear element wherein controlled flow of molten zinc onto the linear element is effected through one or more nozzles, whereby galvanizing may be accomplished without immersion of the linear element in molten zinc. In a preferred embodiment, the apparatus of the invention comprises an annular nozzle having a central opening through which the linear element is axially advanced. The nozzle is configured to provide a converging, generally frustoconical curtain of molten zinc flowing continuously onto the exterior surface of the linear element.Type: GrantFiled: February 29, 1996Date of Patent: January 5, 1999Assignee: Allied Tube & Conduit CorporationInventors: Kalyan K.

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: 5718027Abstract: An improvement is accomplished in apparatus for the continuous production of tubing from tubing stock, and like, elongated, closed structures from appropriate stocks. The apparatus includes welding means for continuously welding the tubing stock to form the tubing, with the welding occurring at a welding station. Downstream of the welding station are stations for the further processing of the tubing after welding, which generate conditions adverse to interior coatings. In apparatus as described, the improvement comprises several inventive features. A spray head provides for spraying of coating, and fits within the tubing. An elongated, flexible lance locates the spraying means downstream of the processing stations which generate adverse interior coating conditions, by introduction of the spray head into the tubing interior upstream of the welding station, and after introduction, movement of the spray head into the desired downstream position.Type: GrantFiled: September 23, 1996Date of Patent: February 17, 1998Assignee: Allied Tube & Conduit CorporationInventor: Bruce E. Laumann

Patent number: 5614265Abstract: A method and apparatus for applying a coating to a continuous length of tubing. A coating chamber having entry and exit ports substantially encloses a portion of the tubing while permitting the tubing to pass continuously therethrough. Airflow into the coating chamber through the exit port strips excess coating material from the tubing surface. Air is withdrawn from the coating chamber by vacuum pumps through one or more separation chambers which separate entrained particles or droplets of coating material from the air. The coating chamber is preferably disposed at a distance from the separation chamber(s). The vacuum line connecting the coating chamber with the separation chamber(s) is preferably flexible or breakable. The separation chambers are preferably capable of being operated in series or in parallel. Adjustable masks are preferably provided at the entry and exit ports of the coating chamber. A seal is preferably provided at the entry port.Type: GrantFiled: February 14, 1995Date of Patent: March 25, 1997Assignee: Allied Tube & Conduit CorporationInventors: Manzoor A. Chaudhry, Jeffrey L.
