Abstract: A system by which external users, such as subscribers and service providers, can update their service data is disclosed. The system permits users to update their service data in a secure and controlled manner on a self-service basis in an intelligent network or other telecommunications network. An access system separate from the actual telecommunications services managing network elements is implemented in the invention, the access system providing the customers and service providers with an open interface to these network elements through a public data network. The access system controls access to the actual network elements by, for example, authenticating the party requesting access, checking whether the requesting party is associated with the data he/she desires to manipulate, and/or checking to which processing operations the requesting party is entitled. The users can thus access their own service data in the network elements managing the data in a manner controlled by the access system.

Abstract: Liquid gas is discharged from the supply channel (61) in the fixed object (5), into an annular groove (62) formed in a contact surface (45) between fixed (5) and rotating (4) objects. It is forced on, into a channel (63, 64.1, 64.2) in the rotating object, making its way to the part to be cooled (15). Once there, it picks up heat of vaporization and is led away in gaseous form. Independent claim is also included for a corresponding equipment carrying out the process Preferred Features: In the region (65) surrounding the part to be cooled, a larger cross sectional area (2AE) is available for liquefied gas flow. This area exceeds the sum (AK641 + AK642) of cross sectional areas in the supply channels (63, 64.1, 64.2). Thus the liquefied gas can absorb heat, evaporate and expand in this area. The cross sectional area available to gas flow between fixed object and cooled part is constant or reduced, to avoid expanding the liquefied gas; the area may in fact be reduced, to compress it. Liquefied gas is directed towards the rotation axis (a), into the annular groove. The gas is carbon dioxide.

Abstract: Reactive Dye compound having formula (I), wherein D is a chromophore group; L is a linking moiety; Q is a quaternized nitrogen derivative; X and Y are independently selected from chlorine, bromine fluorine or hydrogen; A is selected from halogen, preferably chlorine or fluorine; provided that at least one of X and Y is fluorine; and the salts and esters thereof. The reactive dye compounds of the invention exhibit high Exhaustion Values, high Fixation Values, particularly on cellulosic substrates such as cotton, and show significant improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, increasing the dye-substrate covalent bonding, increasing the ability to dye substrates at room temperature, decreasing the amount of dye that is removed during the post dyeing "soaping off process" and therefore simplifying the post dyeing "soaping off process" traditionally associated with dyeing cotton with fibre reactive dyes and reduction of staining of adjacent white fabrics. In addition, the compounds prepared above provide more intense dyeings and require less levels of salt for dyeing cotton substrates.
