Publication number: 20120255272Abstract: To protect the end of a cable composed of a set of tendons individually held in an anchorage system, the device comprises a skirt extending from the front of the anchorage system and placed around the set of tendons, and several sleeves. The tendons have respective end portions which extend beyond the front of the anchorage system and which are individually received in the sleeves, said sleeves being sealed off beyond the end portions of the tendons. A connection between the skirt and the sleeves encloses a chamber delimited by the front of the anchorage system, the skirt, and the sleeves, the connection comprising an active stuffing box kind of system. The volume of this chamber is filled in with a filling product.Type: ApplicationFiled: April 5, 2012Publication date: October 11, 2012Applicant: Soletanche FreyssinetInventors: Stephane JOYE, Yannick LE GOFF

Patent number: 6182434Abstract: The process is carried out on a spinning system that has a driven spindle (13) and a balloon limiter (14) concentric with it, driven in the same direction as the spindle (13) an provided with an inner work surface (44). For the purpose of reaching the high operating speed, the yarn (P) entrained by the work surface (44) and running toward the tube (23) on the spindle (13) is first always given by the centrifugal process the shape of a rotating, open loop (48), from which the yarn (P) is subsequently drawn off and coiled directly onto the tube (23). In this connection, this rotating, open loop (48) can be radially delimited by a rotating or stationary limit ring (28).Type: GrantFiled: August 28, 1998Date of Patent: February 6, 2001Assignee: Vyzkumny Ustav Bavlnarsky A.S.Inventors: Václav Kubový, Petr Bla{haeck over (z)}ek, Stanislav Dídek

Patent number: 5590515Abstract: In a spinning apparatus including a rotatable spindle carrying a package for receiving a yarn from a yarn guide which is arranged in axial alignment with the spindle, a tubular element surrounds the package and the spindle and is floatingly supported by magnetic bearings and a second yarn guide is arranged so to be rotatable within the tubular element and receives the yarn for guiding it onto the package with a winding speed corresponding to the rotational speed difference between the spindle and the tubular element and sensors are arranged adjacent the tubular element for sensing any axial deviation of the tubular element from its desired position which axial deviation is taken as a measure for the yarn tension forces.Type: GrantFiled: December 19, 1995Date of Patent: January 7, 1997Assignee: Forschungszenlrum Julich GmbHInventor: Karl Boden

Patent number: 4959953Abstract: A funnel for delivering yarn for building a package on a spindle of a spinning machine has an entry channel for the passage of yarn therethrough into the interior of the funnel and an exit opening for the passage of yarn therethrough from the interior to the exterior of the funnel, the interior of the funnel having a lateral extent sufficient to allow the formation of a yarn balloon of controlled extent during building of the package on the spindle. The funnel can contain a guide portion projecting interiorly of the funnel at a spacing from the entry channel and a neck portion in which the entry channel is formed.Type: GrantFiled: November 30, 1988Date of Patent: October 2, 1990Assignee: Zinser Textilmaschinen GmbHInventor: Stefan Krawietz

Patent number: 4953350Abstract: A yarn feeding funnel for a textile spinning machine having an upper shaft portion and a body portion. A yarn inlet opening in the upper shaft portion is radially offset from the axis of rotation of the yarn feeding funnel and facilitates the formation of a yarn balloon of controlled extent between the yarn inlet opening and a yarn guiding eye which is coaxial with the funnel rotation axis. A plurality of alternative yarn inlet openings, each at a predetermined, different radial spacing from the funnel rotation axis, may be provided to vary the characteristics, such as the diameter, of the yarn balloon formed between the yarn inlet opening and the yarn guiding eye.Type: GrantFiled: April 19, 1989Date of Patent: September 4, 1990Assignee: Zinser Textilmaschinen GmbHInventors: Gunter Schulz, Frieder Probst, Hermann Guttler

Patent number: 4951456Abstract: The cap of a cap spinning device comprises a thread introduction attachment in the top or upper region of the cap. In this thread introduction attachment there is arranged an inlet passage which is upwardly directed at an inclination and provided for the thread coming from the drafting arrangement via a thread eye, so that a balloon is formed between the thread eye and the top or upper side of the cap.Type: GrantFiled: January 19, 1989Date of Patent: August 28, 1990Assignee: Rieter Machine Works Ltd.Inventors: Angelo Lucca, Andre Lattion
