    • A high pressure sealing arrangement of the type in which a rotor sealing ring end face defines a gas pressure with a stator sealing ring end face has a functional gap between a cylindrical portion of the seal housing and the stator sealing ring bridged by an O-ring of reduced hardness. The polar or geometric moment of inertia of the stator sealing ring is sufficiently large that the gap width of the functional annular gap between the shaft-side cylindrical part of the sealing ring in the operational state and under the operational differential pressure corresponds to the structurally predetermined gap width of the mounting ring gap between the cylindrical part of the sealing housing and the stator sealing ring in all operational states and is less than 0.4 mm and preferably less than 0.3 mm. The sealing O-ring additionally serve as a compensation or centering ring and, for this purpose, has a material hardness which is greater than the extrusion threshold of this material through the gap and for the given gap width at the predetermined operating pressure differential and is less than a hardness of 90 Shore A according to German Industrial Standard DIN 53505 preferably the hardness of the O-ring is less than 80 Shore A under this standard. In other words according to the invention the parts are related and dimensioned that the orientations of the sealing end faces of the rotor sealing ring and the stator sealing ring do not change in operation and preferably are always parallel.

    • A turbocompressor shaft seal, especially for a high-pressure turbocompressor, has each of its gas-side and atmosphere-side slide rings biased toward a rotor ring of the shaft and associated with blocking-liquid compartments which are interconnected by an annular passage aroung the rotor ring. The compartments are connected in a closed circulation path with a circulating pump and a cooler and leakage liquid is returned by a feed pump to the liquid circulation with the aid of a pressure transformer biased on one side by the gas pressure to be sealed and an adjustable spring force and, on the other side, by the pressure of the blocking liquid. The surface area ratio K between the area of the atmosphere-side slide ring biased by the blocking liquid pressure toward the rotor ring and the sealing area of the atmosphere-side slide ring is substantially 0.45 to 0.60, the thermal conductivity of the slide rings and rotor rings is greater than 250,000 N/mm.sup.2 and the thermal conductivities thereof are greater than 70 W/mk.

    • An apparatus for slitting a web moving along a path in a transport direction has a support transversely shiftable relative to the web adjacent the path, a drive shaft extending transversely of the direction adjacent the path and substantially nonmovable transversely of the path, and a drive gear on the support rotationally coupled gear to the drive shaft and shiftable along the shaft. A mount shiftable toward and away from the shaft on the support carries at least one driven gear and a driven blade fixed to and rotatable with the driven gear. Another blade is juxtaposed with the driven blade and flanks the path therewith. An actuator can shift the mount between a cutting position with the blades closely juxtaposed and the driven gear meshing with the drive gear and a retracted position with the blades separated and the driven gear out of mesh with the drive gear.

    • A core chuck for a web-winding machine has a drive shaft extending along an axis and having an outer periphery of polygonal shape seen axially and a hub having a central hole with a polygonal shape substantially complementary to the shaft and fittable with limited clearance over the shaft. A plurality of outwardly directed faces on the hub engage respective jaws and are angled such that relative rotation between the hub and the jaws radially displaces the jaws. A retaining screw extending along an axis of rotation of the shaft through the hub has a threaded shank seatable in the shaft and a head engageable axially in one direction with the hub. A cover disk axially fixed on the hub is formed on the axis with a hole of smaller diameter than the head of the screw. The screw head is captured axially between the disk and the hub.
