Abstract: Methods and apparatus, including computer program products, are provided for data replication. In one aspect, there is provided a computer-implemented method. The method may include providing an initial load of a data item from a source system to a target system, wherein the data item is associated with a trigger maintained at the source system; recording a change in a log, when a change to the data item at the source system causes the trigger to prompt the recording; extracting the change from the log to enable at least a confirmation of a consistency of the change; and providing the extracted change to a replication server configured to write the change to the target system.

Abstract: A transmission has a lubricant pump which is arranged in the interior of a transmission housing and which includes a rotor rotationally fixedly connected to a transmission shaft in a pump housing, with the pump housing being rotationally fixedly connected to the transmission housing and being sealed with respect to a cylindrical sealing surface of the transmission housing, and with the lubricant pump pumping into a pressure chamber which surrounds the transmission shaft and which is sealed with respect to the transmission shaft. To achieve a good seal and centration of the pump housing, the pump housing is sealed by means of a resilient ring with respect to the cylindrical sealing surface of the transmission housing, with the ring being received by an outer peripheral groove of the pump housing with radial clearance so that the pump housing can adjust itself in the radial direction.

Abstract: The invention relates to a gearbox comprising a shift fork (4) that is displaced by an actuator using a shaft (2), whereby a rotational displacement of said shaft is translated into a displacement of the shift fork. To achieve an accurate displacement with minimum installation space, the gate (14) is configured on a sleeve (13) that is connected to the shift fork unit (4) in a rotationally fixed manner, said sleeve acting on the shift fork unit (4) in the direction of the displacement by means of a spring (24) and the shaft (2) runs through the sleeve (13), said shaft comprising a finger (11) that protrudes radially and co-operates with the gate. The shift fork unit (4) forms a housing (8) that surrounds the sleeve (13) and the spring accumulator (24) and that comprises bearing surfaces (34), by means of which the shift fork unit (4) is guided on the shaft (2) in the direction of the displacement.

Abstract: The invention relates to a multiplate wet clutch with a rotatable clutch hub which is rotationally fixedly connected to a plurality of inner plates which can be placed in frictional engagement with outer plates of an associated clutch cage, wherein the multiplate wet clutch has at least one fluid inlet opening which permits a fluid flow out of a fluid supply space to the plates. Arranged in the fluid flow path between the fluid inlet opening and the plates is at least one particle retention device.

Abstract: The invention relates to an open-loop control process for the motional guidance of conveyed material (32) in a conveying device (30) and to a corresponding conveying device (30). The conveying device (30) has a movable means (36) for realizing the conveyance and a first motion detector (42) for measuring a first actual position value (x1act) for the movable means (36) and a second motion detector (40) for measuring a second actual position value (x2act) for the conveyed material (32).

Abstract: The device is arranged in the form of a complete assembly group on two plates (1,2) screwed together by spacer bolts (18). Guide slots (1a,1b,2a,2b) of similar arrangement and design serve for positively guiding a reciprocable carriage (9,10). The carriage (9,10) comprises a guide member (9) with guide rollers (12,13,33,34) which are supported on ball bearings, bars (3,4) being hinged to the guide member which at their other ends are hinged to drivers (5,6). The drivers (5) are secured to toothed belts (7,8) guided and driven by gear wheels (16,30) mounted on the plates. A carrier (10) is mounted on the guide member (9) so as to be shiftable, liftable and tiltable and supports a pivotally mounted suction plate (11,22). The guide slots are arranged in a position inclined towards the cassette (27) to be unloaded while the toothed belts (7,8) are arranged in an angular position opening in this direction.

Abstract: For separating sulfur from a sulfur-lye suspension, the suspension is fed into a flooded separation tank, a temperature above the melting temperature of sulfur is maintained in the separation tank, and liquid sulfur and lye are withdrawn from the separation tank. To reduce the formation of sodium thiosulfate, the area of the interfacial separation layer between liquid sulfur and lye is maintained as small as possible in separation tank (15) by providing that the liquid sulfur be fed into a relatively small diameter vertical separation pipe (4), in which the separation layer (6) between liquid sulfur and lye is established, and the liquid sulfur is drained out through separation pipe (4).

Abstract: For the separation of sulfur from a sulfur/alkaline solution suspension, the suspension is heated to a temperature above the melting temperature of the sulfur and is introduced under pressure into a separating tank 1, containing a separating chamber 8, alkaline solution chamber, and sulfur chamber 12. From the separating tank, settled liquid sulfur is continuously withdrawn, on the one hand, via conduit 16 and alkaline solution is continuously withdrawn, on the other hand, via conduit 9. In order to provide a system having little susceptibility to trouble, the separating chamber and alkaline solution chamber are operated in the flooded mode, thereby avoiding the necessity for a steam blanket therein.

Abstract: Methanol is prepared by catalytic conversion of a synthesis gas mixture, containing hydrogen, carbon monoxide, carbon dioxide and/or water, at from 200.degree. to 320.degree. C. and under from 30 to 300 bar in adiabatic and/or isothermal reactions in the presence of a catalyst containing copper and zinc, by a process in which the fresh catalyst is reduced with a hydrogen-containing gas before the start-up of the process, and then the synthesis is started under conventional conditions and is continued until the formation of methanol in the reaction zone has declined substantially, after which the reaction is interrupted and the catalyst is regenerated.

Abstract: In the scrubbing and simultaneous oxidation of hydrogen sulfide with an aqueous alkaline scrubbing solution containing five-valent vanadium as the oxidizing agent, the sulfide being converted into higher oxidation states with simultaneous reduction of the five-valent vanadium to four-valent vanadium, the scrubbing solution subsequently being regenerated for reuse in a downstream oxidizer by treatment with an oxygen-containing gas for the reoxidation of the four-valent vanadium, to avoid losses of vanadium when the pH in the scrubbing solution is below 9.5, using the vanadium in a ration which exceeds the stoichiometric ratio for the oxidation of the hydrogen sulfide.

Abstract: In a process wherein hydrogen sulphide is removed from a gaseous mixture by scrubbing with an aqueous alkaline scrubbing solution containing an oxidizing agent, which process ordinarily results in a buildup of S.sub.2 O.sub.3.sup.-- ion, in order to reduce the rate of formation of S.sub.2 O.sub.3.sup.-- ions, the pH of the alkaline scrubbing solution is maintained at below 9 preferably at 8.0-8.5, with CO.sub.2 being preferably employed as the pH adjusting reagent.

Abstract: In the simultaneous scrubbing and oxidation of H.sub.2 S with a vanadate-containing aqueous alkaline scrubbing agent, so as to prevent precipitation of vanadium values, the concentration of CO.sub.3 -- ions in the scrubbing agent is adjusted, preferably to a minimum content of CO.sub.3.sup.-- ions of 12.5 g/l of scrubbing agent. The scrubbing agent is regenerated conventionally by treatment with an oxygen-containing gas in an oxidizer.
