Abstract: An in-line separator is provided for separating fluid phases of different density from a fluid stream. The in-line separator comprises a conduit having an inlet section (2) for receiving the fluid stream, an outlet section (12) for separately transporting the fluid phases, and a swirl section (4) for inducing a swirling motion to the fluid stream as the stream flows from the inlet section (2) to the outlet section (12), the swirl section having an interior space (19a). At least a portion of said interior space forms a passageway (19a) for passage of tools from the inlet section (2) to the outlet section (12).

Abstract: A new method is disclosed, for upgrading the software in a real-time distributed software system comprising several processes running in parallell. The method involves a preparatory procedure in which the new software is installed. Then, the software is activated, the components ordered to save configuration data and transaction data in a database, whereupon the components are stopped. When the preparatory procedure is completed, a restart procedure is invoked. This involves selecting start level (full upgrade involving all components, or a partial upgrade concerning just one or a few components). The modules concerned are started from the new software version. On each start level a number of start phases are defined. These are sequential steps performed during the restart operation. Each module subscribes to a number of these phases. Some of the phases are defined as synchronisation points, here called service levels, which all modules have to arrive at before the process is allowed to commence.

Abstract: A method and system (i) for improving the handing over of a connection from one SGSN (I) to another, i.e. when an MS (Mobile Station) moves from one SGSN service area to another, (ii) for not interrupting the packet transmission and possible layer 3 procedures, and (iii) for optimizing the network utilization without adding complexity to SGSN. Upon an inter SGSN routing area update, the old SGSN (I) is given the role as a temporary anchor, whereas the other (new) SGSN (II) is temporarily working as a serving SGSN.

Abstract: The invention relates to a process control in telecommunication systems, in particular GPRS. The invention is a system and a method for implementing several independent state machines in the same process. It describes how to organise the state machines in a tree, how they access their data and how to offer them some generic support, such as informing them of a common event.
