Abstract: An apparatus for an aircraft includes an electric machine and a gas turbine. The gas turbine includes a compressor, a turbine unit having a high-pressure turbine and a low-pressure turbine, and a combustion chamber. The compressor is connected via a high-pressure shaft to the high-pressure turbine, and the low-pressure turbine is connected via a low-pressure shaft directly to an output shaft of the electric machine. The high-pressure shaft and the low-pressure shaft are rotatable in different directions. The electric machine is operable as a generator and may be operated as a motor to start the gas turbine. The output shaft is connected via a gear box unit and a free-wheel to the high-pressure shaft. The free-wheel separates the connection between the output shaft of the electric machine and the high-pressure shaft in the presence of a torque flow from the high-pressure shaft in a direction of the output shaft.

Abstract: A controller controls a balancer circuit, and is configured to: determine a difference value between a first DC link voltage value across a first DC link of a power converter and a second DC link voltage value across a second DC link of the power converter; determine a phase-angle and a magnitude of the difference value for an integer harmonic of a predetermined grid frequency; and provide a switching signal for switching between the first DC link and the second DC link based on the phase-angle and the magnitude. The controller is also configured to control a mid-point current at a mid-point terminal of the power converter in terms of magnitude and direction based on the switching signal.

Abstract: Collection device for connecting a drilling tool, such as a bit, to the end of a drilling column, in which the connection device comprises a first element, with a first end, intended to be connected to the end of the drilling column, and a second element, with a second end, intended to be connected to the drilling tool, in which the second element is fixed to the first element so as to allow a translational movement in a longitudinal direction in order to make it possible to change the distance between the first end and this second end, characterized in that the connection device comprises a “pusher” structure for transmitting a thrust force from this first element towards the second element, comprising a set of “Belleville” washers making it possible to ensure that said thrust force, from the first element toward the second element, is substantially constant in any position of the second element with respect to the first element.

Abstract: Two-centre rotary boring bit for boring wells, comprising, on the one hand, a pilot tool (1) comprising a body of revolution with an axial core (3) and radial blades (4) bearing cutting elements (5) and, on the other hand, an enlarging tool (2) fitted behind the pilot tool and laterally offset therefrom, the pilot tool having, on its front face, a central region (11) that has no cutting elements in order to allow the creation of a core sample (12), said central region being in communication with a cavity (13) situated between two blades (4) of the pilot tool (1) and serving to remove the core sample toward the periphery of the boring bit.

Abstract: A reinforcing net for use in a reinforcing layer is formed by spacing two parallel spreader yarns under tension and wrapping weft yarns around the two spreader yarns. The reinforcing net can either be affixed to an adhesive coated substrate or coated with adhesive at the intersections of the yarns to bond the net together. The net may be affixed to a plurality of substrates to form a laminate. The net, a ribbon of net with one substrate, and the laminate, may be used in making and reinforcing spirally wound products such as ducts, duct insulation and the like. A number of warp yarns can be included in the reinforcing net to increase its strength. The method of manufacturing the reinforcing net includes the steps of creating tension in the spreader yarns, providing a least one spool for supplying weft yarn, longitudinally advancing the spreader yarns, rotating the spool around the advancing spreader yarns and applying adhesive to the intersections of the yarns.

Abstract: A method for extending the capabilities of an arbitrary web server operating in a client-server environment (e.g., the Internet). When a client makes a request to the web server, the request may include an address for a code module needed to service the request. If the code module is not available at the web server, the web server uses the address to request the code module from another location. The code module is then served to the web server and installed. The web server then responds to the original client request using the installed code module. In an alternative embodiment, the code module is uploaded to the target server from the client.

Abstract: A method and apparatus in a data processing system for generating suggested content for a site. A request is received for content for the site from a client, wherein the content is requested content. The requested content is sent to the client. The requested content includes information used to track user movement within the site. Suggested content is generated using the information in response to the client requesting the suggested content.

Abstract: The present invention protects images via a server-based policy that results in the selective distribution of one of multiple versions of an original image. The policy includes a set of one or more rules that each include given criteria. When a request for a web page is received, a given rule in the set is evaluated against client-specific data (e.g., such as client IP address, the identity of the referring page, or the like) obtained from the client request. If a condition of the rule is satisfied against the client-specific data, a given restriction is imposed on the image distribution.

Abstract: A method for reuse of image data in a distributed computer network is operative at a web server in response to a request from a client browser for a web page. At the web server, a determination is made regarding whether the web page includes a given object reference. If so, a template defining a composite image is retrieved. The template identifies at least one image object to be retrieved from another location, typically from a host remote to the web server. Once the image object is retrieved, a given transform is applied to the image object to generate a transformed image object. The given transform, for example, is selected from a group of transforms such as: scaling, mirroring, cutting, cropping, inverting, flipping, reversing, rotating, color shifting, and combinations of the above. Thereafter, the transformed image object is mapped into the composite image according to the template. After the composite image is created, it is served within the web page originally requested by the client.

Abstract: A method, system, and computer program product for providing services to a customer is provided. In one embodiment, a customer is provided with a user interface that allows that customer to input a set of desired services and a level of service for each of one or more services. From the set of selected services, a service level agreement and a billing profile for a billing program are constructed. As the selected services are provided, data is sent to the billing program so that the customer may be billed for the services that have been provided. The services provided to the customer are monitored to determine whether the level of service selected by the customer is being met and if the level of service is not being met, an adjustment to the customer's bill is made prior to billing the customer.

Abstract: A system, method, and computer-usable medium for customizing and displaying a network file distributes customization tasks between a client and a server. A client sends a request for a network file, such as a Web page, to a server. The request may include information regarding the client machine type, browser, and customization options (i.e. preferences). Customization options may include personal (i.e. user) options and group (i.e. department, corporate, etc.) options. These options, along with the client machine type and browser, are used by the server to determine how to customize the requested network file. The server obtains the requested network file, and a server-side customization program customizes the file. The server-side customization program may also analyze the network file, and may embed return customization information in the customized network file. The client receives the customized network file, including the return customization information, from the server.
