A combined stent / graft structure for repair of a body tube in a living body. The structure includes a textile graft adapted to enhance fluid integrity of the body tube and a stent expandable between a first position permitting easy insertion of the stent into the body tube and a second position wherein the stent presses securely against the inside surface of the body tube. The stent includes a first elongate wire-shaped stent member with both a stent member global axis and a stent member local axis, and is integrally secured to the graft by at least one graft yarn of which the graft is formed. Substantial portions of the first stent member global axis form a non-orthogonal angle with the graft main portion axis when projected into a plane containing the graft main portion axis. A woven textile is also part of the invention as is a method of manufacturing such a woven textile, which can be used to produce stent / graft structures according to the invention.

A floating liner for a container of welding wire which floating liner includes a tube having two ends and a passageway extending between the two ends. The floating liner is unsupported between the top of the container and the retaining ring. The floating liner is designed to provide structural support to the wire and added stiffness or rigidity to the wire to inhibit buckling of the wire, knot formation in the wire that can form between the retaining ring and the top of the container. The floating liner has a weight profile that causes one end of the tube to at least partially float above the top surface of a layer of welding wire or retaining ring in the container as the welding wire is paid out of the container.

A dispenser adapted to dispense sheet material is provided and includes a housing including a platform configured to support a sheet material thereon. The platform includes a slot, and an adjustable orifice configured to alter a size of the slot is provided as well. The housing is formed to include an exit port which is spaced-apart from the platform. When sheet material is disposed in the dispenser, it flows on a generally serpentine path from the platform and through the exit port.

At least one of two flexible leaf springs that form a thread gap is controlled by a linearly moveable element of a linear motor or drive. Multi-thread brakes are formed by assembling a plurality of such brakes on a common support whereby a single stator may cooperate with a plurality of linearly moveable armatures forming a corresponding plurality of thread brakes or each thread brake may have its own stator and its own armature arranged in a row either linearly or along a curved support, whereby a compact structure is achieved.

A control unit for yarn-braking devices in weft feeders for looms, in which the yarn unwinding from the feeder is pressed between a drum and a braking member connected to two linear actuators controlled by position and provided with position sensors. A position control loop receives a position signal from the sensor and compares it with a reference variable in a subtracter for obtaining a position error. A position compensator receives the position error and outputs a reference current entering a current control loop connected to generate a voltage that supplies the actuator. The compensator incorporates a control transfer function that is variable as a function of an elastic constant of a mass-spring equivalent system, where the mass is the mass of the parts in motion between the braking member and the actuators, and the elastic constant matches with the elastic constant of the elastic elements.

A center-pull dispenser for dispensing paper towels from a continuous roll, wherein each individual towel is separated from an adjoining towel by a plurality of perforations. The dispenser comprises a housing having a housing back and a detachable front cover hingedly connected thereto at the lower periphery of said housing back and front cover for opening and closing the housing, a paper support tray removably connected to a lower portion of the housing back, the tray having a centrally located dispensing nozzle and at least one locking element for releasably locking at least one first hinge element on the lower periphery of the front cover to at least one second hinge element on the lower periphery of the housing back, an opening in the lower periphery of said housing through which the towels are dispensed, and a wall-mounting member for removably mounting the housing back to a wall. In one embodiment, the paper support tray comprises locking arms for releasably locking first hinge elements on the lower periphery of said front cover against second hinge elements on the lower periphery of said housing back. In another embodiment, the dispenser comprises a locking member for releasably locking the front cover to the housing back and the housing back to the wall-mounting member.
