Abstract: An apparatus for winding a flexible web continuously moving in a longitudinal travel direction as rolls onto sleeves has a winding station for holding a sleeve and rotating it about an axis for winding the web onto the sleeve. Upstream of the winding station at a changeover station a fresh sleeve is held adjacent the continuously moving web. A shell juxtaposed with the fresh sleeve in the changeover station forms therewith a gap. A cross-cutter for the web is provided adjacent an end of the gap and can form on the web a trailing end and a leading end so that the trailing end travels to the winding station for winding on the sleeve therein. Air is drawn air into the end of the gap to aspirate the leading end into the gap. This leading end is electrostatically adhered to the fresh sleeve in the changeover station.

Abstract: An escalator handrail drive arrangement includes a drive belt (26) mounted within a drive housing (35). Pressure rollers (30) are mounted in pairs and pivotally attached to the drive housing. The pressure rollers bias a handrail (22) against the drive belt. The pressure roller arrangements are mounted at each axial end. A spring (44) biases the pressure roller arrangements against the handrail, with the spring being centered along the axial length of the pressure rollers. This spring is preferably mounted within the drive housing such that no additional space is required outwardly of the drive and roller arrangement to accommodate the spring.

Abstract: A tubular heat exchanger includes a substantially cylindrical sheathing tube having a center piece and two end pieces of a length which is shorter than a length of the center piece. Two perforated bases are respectively received in the end pieces and sized to occupy a cross section thereof, and two end caps are respectively secured to axial ends of the end pieces. Extending in substantial parallel relationship inside the sheathing tube between the perforated bases are a plurality of internal tubes to thereby define a first fluid space between an inner surface of the sheathing tube and outer surfaces of the internal tubes, and a separate second fluid space bounded by inner surfaces of the internal tubes and the end caps on the end pieces. A lateral connection pipe is secured to each end piece and fluidly communicates with the first fluid space in a region adjacent to the perforated bases for supply and drainage, respectively, of a first fluid flowing through the first fluid space.

Abstract: The invention relates to a method for the diagnosis and risk stratification of a tumor or cancer of the gastrointestinal tract, particularly colon tumor or colon cancer, wherein a determination is made on at least one patient using the novel soluble cadherin 17 biomarker—a proteolytic cleavage product of cadherin 17 having SEQ ID No. 1 or SEQ ID No. 2—or partial peptides and fragments thereof.

Abstract: An electrical voltage supply device for machines processing printing material includes at least one drive motor for the transport of printing material and at least one further electrical consumer. A control unit is provided which, when the supply voltage drops below a minimum acceptable supply voltage of the machine processing printing material, switches of electrical consumers which are not required for the transport of printing material and supplies the drive motor for the transport of printing material from energy stored in the moving masses of the machine processing printing material.

Abstract: A winding device for winding a continuously arriving material web onto a reel, including a contact roller by which the material web can be guided and transferred to the reel in contact with the surface of the contact roller. The contact roller has a support tube and fibers, which protrude from the outside of the support tube and form the surface of the contact roller. The fibers extend essentially perpendicular to a longitudinal axis of the contact roller so that first ends of the fibers are affixed to the support tube and their other free ends define a surface of the contact roller.
