Abstract: A fan nacelle for an aircraft gas turbine engine. The nacelle includes an aft nacelle portion including a radially outer surface and a radially inner surface, the radially outer and inner surfaces defining an internal cavity therebetween. The nacelle further includes an aft nacelle segment translatable along a translation vector having an axial component, wherein the aft nacelle segment is configured to translate between a forward deployed position in which the nacelle defines a first primary fan nozzle exit area (A1) and a clean position in which the nacelle defines a second primary fan nozzle exit area (A2) less than the first primary fan nozzle exit area A1, wherein in the forward deployed position, the aft nacelle segment is at least partly located within the internal cavity.

Abstract: A turbofan engine includes an outer fixed structure, the downstream terminal end of which terminates in a terminal plane substantially normal to the longitudinal axis of the engine. The radius R of the internal surface of the outer fixed structure in the terminal plane is a function R(?) of azimuthal position ? such that the radius has a constant value R0 within a first azimuthal interval of 180°, a value greater than R0 at any azimuthal position within a second and fourth azimuthal intervals and a value less than R0 at any azimuthal position within a third azimuthal interval, the azimuthal intervals forming a total interval of 360° and the fourth interval being contiguous with the first. The engine may be mounted closer to the airframe of an aircraft than a turbofan engine having an outer fixed structure which is axisymmetric in its downstream terminal plane.

Abstract: A turbofan engine comprises a nacelle and an engine core having a core cowling. The internal surface of the nacelle and the external surface of the core cowling define a bypass duct having an exhaust end defining a bypass duct exit plane generally normal to the longitudinal axis of the engine. The core cowling extends aft of the bypass duct exit plane and has an annular or partly-annular exit ventilation nozzle located aft of a first longitudinal position and fore of a second longitudinal position, the first and second longitudinal positions being respectively fore of and either aft of or coincident with the bypass duct exit plane, the core cowling otherwise being free of exit ventilation nozzles fore of the second longitudinal position. The engine has a lower specific fuel consumption than an equivalent engine having an exit ventilation nozzle in a conventional position aft of the second longitudinal position.

Abstract: A gas turbine engine includes a core engine having a working gas annulus which ends in a core exhaust nozzle for exit of hot gas from the core engine. The engine further includes a bypass duct which ends in a bypass exhaust nozzle for exit of bypass air from the bypass duct, the bypass exhaust nozzle being forward of the core exhaust nozzle, and the bypass duct having an inner wall which forms a surrounding cowl of the core engine and ends at the bypass exhaust nozzle. The engine further includes a core cowl after-body which provides a frustoconical air-washed surface continuing unbroken, on a longitudinal section through the engine, the line of the bypass duct inner wall downstream of the bypass exhaust nozzle. The air-washed surface of the core cowl after-body has plural axially-spaced circumferentially extending corrugations which locally disturb the flow of air over the surface.

Abstract: A system and method can support a communication in a computing environment. A dependency injection (DI) based event system can be used to support the communication between a topic publisher and a topic subscriber in the computing environment. The system can use a topic service to distribute one or more messages from the topic publisher to the topic subscriber. Furthermore, the event system can provide a service provider interface (SPI) between the topic publisher and the topic subscriber. The event system delegates to the SPI one or more decisions on how the producer and the consumer are related in the computing environment, such as allowing a user, e.g. a system designer/assembler, to choose a quality of service (QoS) for supporting communication between the topic publisher and the topic subscriber.

Abstract: The Flexible Message Header (FMH) is a typed modular message structure comprising one or more Typed Container Modules (TCM)—stateful message modules with a compact header (Typed Container Header, TCH), a user definable payload (Typed Container Body, TCB), and a set of payload-specific callback to handle the lifecycle of the module at the different state such as creation, preparation, manipulation, resizing, transferring, and deletion. A single message comprises a small header with various numbers of TCMs. The integrity of the entire message is not affected by dynamically modifying, adding or removing TCM from the message. Major message content change can be achieved by either adding a TCM or swapping the TCM with different TCM. Minor message content change can be achieved by either modifying or expanding the TCM directly within the message. New features can be supported by adding new TCM and new code to process the new TCM.

Abstract: A method, and apparatus for transferring a fluid to a sterile field includes the use of a sterile enclosure (58, 68) housing a syringe (40). The enclosure (58, 68) is made in two parts, and allows the syringe (40) to be operated while it is in the enclosure. When it is desired to pass the fluids to the sterile field, the enclosure is separated into at least two parts to allow the syringe to be removed. This removal of the syringe is done such that the user in the non-sterile field does not touch the syringe. Thus, the syringe, and fluid therein are easily transferred to the sterile field.

As disclosed herein the invention applies the operation of public key technology to transactional server security. Embodiments of the invention utilize a combination of message-based encryption and message-based digital signing, to ensure the security and authenticity of a message or message buffer sent from one party or process to another. Intermediate recipients may also inspect the message. The system described ensures the reliable authentication, confidentiality, integrity, and non-repudiation, of communicated messages.

Abstract: The invention provides a system and a method which utilizes a combination of message-based encryption and message-based digital signing to ensure the security and authenticity of a message or message buffer sent from one party or process to another in a transaction processing system. In one embodiment the invention includes a method comprising the steps of: creating an encryption envelope by encrypting a message buffer, signing the encrypted contents of said message buffer with a digital signature, sending said encryption envelope from the sender process to the recipient process, receiving the encryption envelope at the recipient process, decrypting said encryption envelope to retrieve said message, and verifying the identity of the sender process by retrieving the digital signature from the encryption envelope. The invention allows intermediate recipients to inspect the message, and provides for reliable authentication, confidentiality, integrity, and non-repudiation, of communicated messages.

Abstract: A centrifuge is capable of holding a sample container in selected orientations, either during or after centrifugation, to drain supernatants between two or more chambers of the container. The draining may be gravity or centrifugal draining. This allows an automated process to subject a sample to a first physical or chemical treatment to produce a first supernatant, the first supernatant to be subjected to a second physical or chemical treatment, and a second supernatant to be separated from a desired component.
