Abstract: A constraint arrangement for a stent-graft loaded onto a delivery device. The stent-graft has a graft body defining an elongate lumen and a positionable region. At least one apposition release wire releasably secures the graft body to the guide wire cannula along a length of the guide wire cannula. A suture is sewn circumferentially through and around the graft body, such that a plurality of internal suture portions are formed. A constraint loop is formed from a first of the internal suture portions. A plurality of reducing loops are formed from others of the internal suture portions. At least one apposition release wire passes through the constraint loop and each of the plurality of reducing loops, and upon retraction of the apposition release wire releases the constraint loop and each of the reducing loops and, thereby allowing the stent-graft to expand and to release from the guide wire cannula.

Abstract: A web and sheet sluice adjustable to different material thicknesses for sheets of paper or the like, which are fed to a processing or treating unit. The sluice has a passage gap between a friction roller, which rotates continuously during the working operation, and an axially parallel braking roller, which is radially adjustable in relation to the friction roller. An electric switching element sends a control signal for an electric circuit during the adjustment of the passage gap to the thickness of a sample located in the passage gap. The braking roller is rotatably mounted on the cylindrical eccentric of an eccentric shaft, which can be driven by a first electric motor drive and can optionally be adjusted to both directions of rotation, and with the friction roller stationarily stopped, it can be driven by a second electric motor drive at a speed of rotation that is substantially higher than the velocity of adjustment of the braking roller via a driving gear which can be moved out of its normal position.

Abstract: The paper folding machine is provided with a roller pair (T1,T2) which forms an intake zone (E) and determines the velocity of feed of the material to be folded, and with at least one pair of folding rollers (W1,W2,W3), which forms a folding zone (F1) and is parallel to the former pair of rollers. A stopless feed limiting device, which determines the actual folding length and can be actuated individually for each folding operation by a microprocessor and/or an electronic control circuit as a function of a feed measuring unit, is arranged in a material feed path (4) which extends past the folding zone (F1,F2).
