  • Publication number: 20110130553
    Abstract: Novel synthesis routes for preparation of thiodigalactosides and intermediates are presented. The method includes the use of a 3-azido-galactosyl thiouronium salt derivative, which is activated to the corresponding thiol in situ, which in turn is directly reacted with a 3-azido-galactosyl bromide resulting in the 3,3?-di-azido-thio-di-galactoside before the thiol has a chance to reduce the azido 10 group. Hence, in situ formation of the 3-azido-galactosyl thiol from the thiouronium salt is essential in the synthesis procedure, because any other method that generate the thiol separately results in extensive unwanted azide reduction.

  • Patent number: 7949479
    Abstract: A rotating machine, has a rotary component, which includes a memory device for storing data relating to the past use of the component. The data are associated with rotational speed and ambient temperature, which are detected by detectors either on or off the rotary component. The stored data may be the raw temperature and speed data as sampled over time, which are then used to derive values of low-cycle fatigue and creep damage. These fatigue and creep values are, in turn, correlated with the load profiles of the component to arrive at a value of elapsed lifespan for the component. Alternatively, the stored data may be the fatigue and creep values and/or, preferably, values of elapsed and remaining lifespan of the component. In a second embodiment the detectors are located on the machine casing along with an evaluation unit.

  • Publication number: 20110090872
    Abstract: A method where a first type location area of a mobile node is registered to a first mobility management node. A second type location area is determined based on a location of the mobile node. A second type location area of the mobile node is registered to a second mobility management node of a second system. A request to perform user plane bearer establishment through the second system is received. Thereupon, radio measurements associated with at least two candidate cells are obtained from the mobile node. Candidate cells are searched to find at least one cell associated with the second type location area. A cell is selected among the at least one cell, which is indicated to the selected cell to the mobile node. A handover request is provided to the mobile node.

  • Publication number: 20110045416
    Abstract: A method for compressing gaseous fuel is disclosed. The method includes, ingesting gaseous fuel into a chamber, ingesting air into the chamber and mixing the gaseous fuel with the air, igniting and partially combusting the resulting mixture of gaseous fuel and air in a confined space such that a predominant fraction of the gaseous fuel is not combusted, causing an increased temperature and therefore an increased pressure of the fraction of the gaseous fuel which is not combusted, and discharging the resulting compressed gaseous fuel. Moreover, a compressor is provided including a casing, a rotor with at least three vanes, an inlet for gaseous fuel, an outlet for gaseous fuel, an air inlet and an igniter. The rotor is placed in the casing such that at least three variable-volume chambers part-bounded by the vanes are formed during a rotor revolution.
