Patent number: 7247359Abstract: A tubular casing for use with food products which includes knitted stockinette, longitudinal threads and circumferential spiral threads that are held to stockinette by stitches located along the length of the casing. Each thread comprises an elastic thread formed from an inextensible yarn spirally wrapped around the outside of a rubber thread. As thread is stretched, the rubber thread extends and the helix angle of the spirally wrapped yarn reduces to the point where the yarn approximates a straight line. The inextensible yarn resists further stretching beyond this point. This point is the elastic limit for thread and it can be adjusted by varying the helix angle during manufacture of the elastic thread. Threads therefore allow the casing to be filed to a predetermined maximum diameter and result in the filled casing having a constant diameter throughout its length.Type: GrantFiled: December 23, 1999Date of Patent: July 24, 2007Assignee: Ennio Pty LtdInventor: Gervasio Mercuri

Patent number: 6709429Abstract: An intravascular catheter having a shaft, at least a portion of which includes a braid reinforcement with a plurality of axial members disposed between the helical members that form the braid.

Publication number: 20030050007Abstract: A fabric air duct with main discharge openings includes additional, much smaller openings that help ventilate the surface of the duct. Ventilating the surface of the duct with a slight yet even amount of airflow helps inhibit the accumulation of condensate and dust on the surface of the duct.

Patent number: 6386237Abstract: The useful life of an abrasive material transport hose (10) can be maximized if the hose is repositioned at the first signs of internal wear. This is accomplished by disposing at least two wear sensing elements (17, 21), each at a specified distance from the inwardmost surface of the inner tube (12), and each monitoring a condition indicative of wear of the hose (10) at its specified distance from the inwardmost surface of the inner tube. When the innermost wear sensing element (17) implies wear, the hose can be repositioned to extend the useful life until the outermost wear sensing element (21) indicates wear requiring replacement of the hose.Type: GrantFiled: August 9, 2001Date of Patent: May 14, 2002Assignee: The Goodyear Tire & Rubber CompanyInventors: Ronald Marcel Chevalier, Andre Georges Cook, Thomas Goodsell Hutchins

Publication number: 20020033196Abstract: The present invention relates to a pressure-resistant hose and forming method thereof, which is capable of effectively spouting liquid or gas of high pressure even though the pressure-resistant hose is of a relatively small thickness, reducing the material cost of the pressure-resistant hose and improving the flexibility of the pressure-resistant hose. The Pressure-resistant hose comprises a first polyethylene mixture and one or more second hose layers. The first hose layer is formed by bonding together longitudinal ends of a first polyethylene mixture fabric coated with one or two watertight films at one or both surfaces of the first polyethylene mixture fabric. Each of said second hose layers if formed by bonding together longitudinal ends of a second polyethylene mixture fabric coated with one or two watertight films at one or both surfaces of the second polyethylene mixture fabric.Type: ApplicationFiled: October 5, 2001Publication date: March 21, 2002Inventor: In Seon Jeong

Patent number: 6349746Abstract: It is a question of an actuating means adapted to be activated by fluid power, which comprises a hose body (5) extending between two spaced head pieces (3 and 4) and whose interior space is able to be subjected to a fluid medium. A strand structure (6) fixed to both head pieces (3 and 4) and extending coaxially in relation to the hose body has two strand groups (18 and 19) in a crossover configuration with bendingly flexible strands (7) extending adjacent to one another with the same longitudinal alignment within a strand group. An intermediately placed yielding material (22) between the strand groups (18 and 19) serves to maintain the strand groups constantly at a distance apart.Type: GrantFiled: November 21, 2000Date of Patent: February 26, 2002Assignee: Festo AG & Co.Inventors: Dieter Bergemann, Bernd Lorenz, Axel Thallemer

Patent number: 6340510Abstract: Woven fabric sleeves are comprised of interwoven glass fiber yarns or similar mineral or ceramic fiber yarns, and hybrid yarns or wires utilized as fill yarns. The fill yarns preferably/consist essentially of glass or ceramic fibers with resiliently settable polymeric materials and/or resilient formable wires or combinations thereof. The wires or hybrid yarns are resiliently set to form resilient hoops yieldably imparting to the fabric side edges a tendency to move into adjacent or overlapping relationship. In one form of the method of making a sleeve, the hybrid fill yarns are resiliently set by placing the woven fabric in a folder, applying heat to cause the fill yarns to assume a set in the wrap around or folded condition and then cooling so that the product is resiliently maintained in the set condition. In an alternative method of making the product, the product is woven on a shuttle loom and one or more wires are used as fill yarns. The wires are fed from pretensioned spools.Type: GrantFiled: May 11, 1999Date of Patent: January 22, 2002Assignee: Federal-Mogul Systems Protection GroupInventors: Joseph P. Hess, Janice R. Maiden, Joan Bitwinski

Publication number: 20020003004Abstract: A developable structural part, such as a component, includes at least one layer made from a resin-impregnated fabric (prepreg) and at least one layer made from wound threads, yarns, rovings or ribbons. At least one constant thread tension, but preferably a thread tension increasing from layer to layer, is applied during winding of the threads, yarns, rovings or ribbons. An outer ply is always formed of wound threads, yarns, rovings or ribbons. A process for producing the structural parts, a thermal insulation cylinder, a protective tube, a heating element, a stay pipe, a hot-press die and a thermal insulation element are also provided. The developable component or structural part can be obtained due to a combination of the application of fabric prepreg layers and windings made from threads, yarns, rovings or ribbons.Type: ApplicationFiled: May 24, 2001Publication date: January 10, 2002Inventors: Werner Guckert, Siegfried Rauch

Patent number: 6230748Abstract: A flexible conduit includes a corrugated tubular metal bellows having a minimum inner diameter; cylindrical end fittings secured to the bellows; a metal hose disposed coaxially within the bellows and having a maximum outer diameter which is less than the minimum inner diameter of the bellows; and a free annular cylindrical space situated between the bellows and the metal hose. The cylindrical space has an outer diameter equaling the minimum inner diameter of the bellows and an inner diameter equaling the maximum outer diameter of the metal hose. The conduit further has a hollow cylindrical knit wire element positioned in the cylindrical space. The knit wire element radially fully occupies the cylindrical space without projecting radially therefrom.Type: GrantFiled: September 6, 2000Date of Patent: May 15, 2001Assignee: Witzenmann GmbH Metallschlauch-Fabrik PforzheimInventors: Tom Krawietz, Fabian Elsässer
