  • Patent number: 8140582
    Abstract: A method, system and computer program product for identifying one or more niche services to combine into a common service, wherein the niche service is a part of a service oriented architecture (SOA). The extensible markup language (XML) schema of the one or more niche services is aggregated into a combined XML schema, wherein the combined XML schema is the XML schema of the common service. A web services description language (WSDL) of the one or more niche services are aggregated to establish a combined WSDL, wherein the combined WSDL is the WSDL of the common service. The common service is generated from the combined XML schema and the combined WSDL. The combined WSDL, utilized to identify the combined service, comprises a service provider URL, one or more service operations, and combined XML schema. The combined XML schema is associated with a common service request and a common service response. When the XML schema of the niche service is not equal with the combined XML schema, mediation is invoked.

  • Publication number: 20090172395
    Abstract: A system, method, and computer program product for transmitting message traffic encapsulating a MQ network having a plurality of MQ clients coupled to a MQ queue via at least one MQ queue manager and at least one MQ proxy server coupled to the plurality of MQ clients. The at least one MQ proxy server retrieves a message from a first MQ client coupled thereto, evaluates the message content and forwards the message to the MQ queue via a designated MQ queue manager. If the destination MQ client is served by a second MQ proxy server the originating MQ proxy server notifies the second MQ proxy server coupled to the second MQ client. The second MQ proxy server retrieves the message from the MQ queue thru the designated MQ queue manager, evaluates the message content and forwards the message to the second MQ client.

  • Patent number: 4755400
    Abstract: An electrophotographic fuser roll includes a hard external surface having low surface energy and high abrasion resistance. This surface is formed by sequentially coating a metal roll with two layers of a polymeric material. The polymeric material is not cured until after the second layer is applied. Once the material is cured, it is subjected to a polishing step that also generates heats. In this way, the roll's surface is both polished and heat treated.

  • Patent number: 4438917
    Abstract: A device for feeding sheets from a supply station aligning the sheets in an X, Y and .theta. coordinates and then gating the sheet into a work station such as the transfer station of a copier. The device includes a pair of independently servo-controlled motors disposed on opposite sides of the sheet. Each motor drives a nip roller which transports the copy sheet. Sensors are disposed to generate signals representative of sheet position in the X, Y and .theta. coordinates. A controller uses the signals to adjust the angular velocity of the motor so that the sheet is squared and is gated onto the work station. The sensors and controller are utilized to measure different parameters associated with the sheet.

  • Patent number: 4424963
    Abstract: A compact single bin finisher adaptable to form collated sets of copy sheets outputted from a copier/duplicator. The finisher includes an output tray adapted to support the collated sets and to support copy sheets during accumulation of a set. A set accumulation module having an accumulation platform is disposed in a plane which is displaced both horizontally and vertically from the output tray. A transport device carries sheets into the accumulation module. A predetermined number of sheets form a set which may be stapled and is ejected onto the output tray.
