Abstract: Certain example embodiments described herein relate to techniques for test automations in emergent systems. More particularly, certain example embodiments provide a mechanism for dynamic recognition of combinations of services/components, monitoring of their real-time usage, and automatic generation and running of tests for the combinations at appropriate times (e.g. when part of a combination is updated). The tests for individual (and, if available, combinations of) services are associated with the services using a registry. A taxonomy or ontology can be used to denote the semantics of the services, providing an array of options for assessing how and when to run tests and actions. It also is possible to detect similar combinations of services automatically.

Abstract: A turbomachine includes a housing and a shaft mounted rotatably relative to the housing about a rotary axis, an element with a through opening through which the shaft protrudes, a first ring element and a second ring element. The first ring element is arranged with its inner surface on the shaft and the element is fixed by the first ring element at a predetermined position on the shaft. The second ring element is arranged with its inner surface lying on the outer surface of the first ring element, which outer surface tapers conically from a first axial end to a second axially opposite axial end. The inner surface of the second ring element tapers conically in a complementary way to the outer surface of the first ring element. An axial movement of the second ring element relative to the first ring element compresses the first ring element against the shaft.

Abstract: The steam turbine has an exhaust-steam casing that can be adapted to various combinations of an inlet casing, connected upstream of the exhaust-steam casing, and a condenser especially simply while maintaining favorable flow properties of the exhaust steam. To this end, the outer jacket of the exhaust-steam casing has a first jacket part in the shape of a cylindrical jacket, which is connected via a stiffening ring to a second jacket part in the shape of a conical jacket. A guide element in the shape of a conical jacket is arranged on the stiffening ring in order to direct the exhaust-steam flow inside the outer jacket.

Abstract: The steam turbine has an exhaust steam housing and a turbine rotor mounted in an end bearing. The turbine installation is intended to have a high stability with respect to movements of the exhaust steam housing, with a particularly high rigidity of the end bearing. For this purpose, the end bearing is held by a support guided through the exhaust steam housing and supported on a foundation block. In a steam turbine installation having a steam turbine of this type, a condenser assigned to the steam turbine is detachably but rigidly connected to the exhaust steam housing.

Abstract: A roll, particularly a back-up roll, for rolling flat material is composed of a rotating roll shell and a unit arranged within the roll shell for influencing the bending stiffness of the roll shell. The unit for influencing the bending stiffness of the roll shell is a friction bearing in the form of a body of rotation. The body of rotation can be adjusted by rotating the body. The body of rotation is shaped in such a way that the load application surface thereof corresponding to the zone of the roll shell to which load is applied is part of the circumferential surface of a rotation-symmetrical body and the edge of this circumferential surface is shaped in such a way that along the circumference of the body of rotation the width and/or position of the load application surface vary.

Abstract: The charting method consists in realising a recordings acquisition, constituting on the basis of the recorded seismic traces, a 3D seismic block (X, Y, T) sampled in elementary cells (C.sub.ijk), such that each elementary cell contains a sample (k) of a central seismic trace (TR.sub.ij), calculating for each elementary cell (C.sub.ijk) of the seismic block, the energy thereof, and fixing an energy threshold beyond which the presence Tk of anomaly zones is considered probable, selecting cells of the block which have energy equal or superior to the said threshold, coding the selected cells, such that all the cells belonging to a same contiguously selected cell set have the same code and the selected cells belonging to distinct contiguously selected cell sets have different codes, and effecting an XY projection of the coded cell block.

Abstract: A rolling mill drive with gear-type joint spindles arranged between driveable rolls and the gear units of the driveable rolls and equipped with a device for circulatory or pressure lubrication of the gear units. Each spindle has a grooved oil supply ring connectable to an oil supply, wherein oil can be supplied through a central duct of the spindle shaft to the gear-type joints, and with a stationary housing surrounding the spindle shaft at a distance and serving for the oil discharge, and with an oil delivery pump connectable on the pressure side to the oil supply rings and interacting with an oil cooler. Each gear-type joint spindle is surrounded by a pipe at a radial distance so as to form an annular oil return duct. The pipe is open at the end facing the gear unit and protrudes into the oil collection housing provided at this location for effecting oil discharge.

Abstract: An x-ray tube has an anode and a cathode arrangement mounted at a distance from the anode and having an electron emitter, the cathode arrangement containing structure for focusing the electron beam that emanates from the electron emitter during operation of the x-ray tube and which is incident on the anode in a focal spot, the focus of the electron beam being located between the electron emitter and the focal spot.

Abstract: An x-ray tube has an anode and an electron emitter from which an electron beam emanates, the electron beam impinging the incident surface of the anode in a focal spot from which a useful x-ray beam emanates. At least in the region of its electron-emitting surface, the electron emitter is formed of an electron-emitting material that has a lower electron affinity than tungsten (a low-temperature emitter). Further, an apertured diaphragm at anode potential is arranged between the electron emitter and the anode and through which the electron beam passes. As electron-emitting material, the electron emitter contains lanthanum hexaboride (LaB.sub.6) or an alloy of the systems iridium/cerium (Ir/Ce) or iridium/lanthanum (Ir/La) systems.

Abstract: A device for axial displacement for a roll in a rolling stand. The roll is mounted in a chock which is guided in a roll housing. The chock is adjustably guided in the rolling stand. The roll is axially displaced by a hydraulic piston-cylinder assemblies acting on the rolling stand and connected to the support member of the roll bearing. The roll bearing is axially slidingly guided in the chock. The chock has a guide for a sliding carriage which is provided with a coupling device for the roll neck. The hydraulic piston-cylinder assemblies are articulated to this sliding carriage.

Abstract: The flame resistance of a bituminized roof sheet consisting of a reinforced fleece, a metal foil and bitumen is improved substantially by applying a metal foil to one face. A rupture of the metal foil in the case of stress due to elongation is prevented by wrinkling it. The elongation reserve thus obtained is in the range of from 2 to 35%.

Abstract: A reinforced plastic belt loop is made by positioning endless shrinkable reinforcement strands circumferentially around a core and shrinking the strands on the core so that the strands become tensioned. Then a hardenable casting plastic is cast in a mold surrounding the core and strands and hardened so that it holds the strands permanently under tension. This forms the belt loop with pretensioned reinforcements.

Abstract: Spunlaid products are provided especially for the manufacture of substrates for polyvinyl chloride coated structured floor coverings. These products consist of crimpfree polyester filaments which are laid down and bonded. Bonding is carried out first by needling at 80 to 300 stitches/cm.sup.2 to a stitch depth of 11 to 20 mm. After needling, impregnation is carried out using a binder liquor consisting of an aqueous dispersion of a copolymer containingfrom 47 to 59 weight % of styrenefrom 33 to 45 weight % of butadienefrom 3 to 4 weight % of acrylic acidfrom 3 to 4 weight % of acrylic acid amideand small amounts of emulsifiers. The binder liquor may also contain the said copolymer and, in addition, from 0.5 to 2 weight % (relative to the copolymer) of a melamine/formaldehyde precondensate etherified with methanol which was prepared using at least one acidic catalyst.
