Abstract: The present invention relates to a monochromator device. The monochromator device includes a first radiofrequency cavity positioned to receive an output beam from an electron source. A second radiofrequency cavity is positioned to receive the output beam from the first radiofrequency cavity. The first radiofrequency cavity and the second radiofrequency cavity are configured to, in combination, in combination, correct one or more energy deviations in time and space of the output beam.

Abstract: A tubular element (1) adapted for use downhole in drilling and oil & gas prospecting comprises a metallic mandrel (6) adapted to be connected (2,3) within a string of elongate elements, with a GRP(GFK) composite material (7) upon an outer surface of the mandrel in which a plurality of ceramic particles are partially embedded to present exposed contact surfaces in the formed composite material. The surface can be ribbed (4) with flow channels (5) therebetween. Suitable particles are of zirconium oxide, silicon nitride, cubic boron nitride, and mixtures of two or more thereof, whereby improvements in weight/strength ratio, fatigue endurance, increased torsional properties, with reduction of wear on the casing are obtained when such composite tubulars of the invention are used as drill pipe or work string sub-assembly elements.

Abstract: A telecommunications service node includes a multi-level architecture comprising an operating system layer interfaced using a compile time linked interface to a service framework layer, and a service application layer interfaced using an object oriented, run time linked interface to the service framework layer. Run time linking of the service applications supports the introduction or modification of service applications during run time execution of the service node. Each service application inherits from the same base class, and is defined by certain criteria which need to be met in order to execute the service. A trader maintains a reference to each available service application. When a certain service needs to be performed, a set of criteria for that certain service are evaluated by the trader, and a particular one of the service applications within the service layer defined to meet the criteria set is selected. The selected service application is then invoked to support the certain service.

Abstract: An automatic activation of a roamer mobile station is implemented in a visited network home location register. Responsive to a registration attempt by the roamer mobile station a default subscriber profile is defined, and a temporary subscriber (directory) number is assigned. Arrangements are also made to insure subscriber payment for any network provided wireless telephone services. Following activation of the roamer mobile station, the default subscriber profile is downloaded for use in providing service. A timer is also started and thereafter monitored for expiration. If the timer expires before the occurrence of a wireless telephone service traffic event involving the roamer mobile station, automatic deactivation of the roamer in the home location register is implemented. In this regard, the default subscriber profile is deleted and the temporary subscriber (directory) number is returned. The billing account for any network provided wireless telephone services is also closed.
