Patent number: 10662895Abstract: 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.Type: GrantFiled: May 12, 2017Date of Patent: May 26, 2020Assignee: ROLLS -ROYCE PLCInventor: John R Wells

Patent number: 10063508Abstract: 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.Type: GrantFiled: March 11, 2015Date of Patent: August 28, 2018Assignee: ORACLE INTERNATIONAL CORPORATIONInventor: John R.

Patent number: 8018946Abstract: 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.Type: GrantFiled: July 22, 2005Date of Patent: September 13, 2011Assignee: Oracle International CorporationInventors: Shean-Guang Chang, John R.

Patent number: 7754494Abstract: 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.Type: GrantFiled: March 11, 1999Date of Patent: July 13, 2010Assignee: Harvest Technologies CorporationInventors: Wesley H Verkaart, John R. Wells, Lin A. Jakary, legal representative, Lou Blasetti, Steven M. Gann

Patent number: 7363495Abstract: 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.Type: GrantFiled: February 21, 2002Date of Patent: April 22, 2008Assignee: BEA Systems, Inc.Inventors: Sandra V.

Patent number: 5916085Abstract: A patient rotator (50) for assisting a patient having limited motion capabilities in lying down on a bed (500) and getting up to the side (502) and method of use are disclosed. The rotator has a frame (52) with a person support member (66) rotatably mounted on the frame at an axis (68) coplanar with the top (504) of the bed and perpendicular to the side. The patient uses a controller (94) to rotate himself on the person support member between vertical and horizontal orientations as desired while he remains on his side.Type: GrantFiled: November 12, 1996Date of Patent: June 29, 1999Inventor: John R.

Patent number: 5895346Abstract: 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.Type: GrantFiled: October 6, 1997Date of Patent: April 20, 1999Inventors: John R.

Patent number: 5282982Abstract: A blood washing device is employed for recovering shed blood or other sources of blood and preparing packed red cells therefrom. The device employs a gravity sedimentation procedure but achieves a shortened washing period by using an aggregating reagent for aggregating or agglomerating the red cells so as to increase their sedimentation velocity during the gravity sedimentation. The wash period is further shortened by employing a vessel with a flat shallow configuration for shortening the sedimentation path length of the aggregated red cells. A non-turbulant removal of the resultant broad shallow layer of sedimented red cells is achieved by carefully tilting the vessel after the sedimentation step so as to induce the sedimented red cells to slide or shift into a funnel configuration within the vessel. After the red cells have shifted into a funnel configuration, they are allowed to stand in that configuration so as undergo further concentration.Type: GrantFiled: July 12, 1991Date of Patent: February 1, 1994Inventor: John R. Wells

Patent number: 5264042Abstract: An apparatus for washing pellets of magnetic particles magnetically bound to the bottom of a test tube employs a liquid handling probe having an aspiration channel with a forked inlet for positioning the probe onto the periapical region of the test tube for optimizing both the aspiration and expression of liquids. While contacting the periapical region of the test tube, the forked inlet may aspirate liquid adjacent to the pellet without contacting the magnetic particles. Furthermore, the contact between the forked inlet and the periapical region of the test tube, serves to position the outlet of the liquid channel directly over the pellet for dislodging and resuspending the magnetically bound pellet with a forceful stream of wash liquid.Type: GrantFiled: April 22, 1992Date of Patent: November 23, 1993Inventors: John R. Wells, Jack R. Uren, Jr.

Patent number: 5195657Abstract: Leakage from the manifold of a manifold type multi-channel dispenser, aspirator, or washer may be diminished by employing siphon shaped pipettes and backsipping liquid from the long leg of such siphon shaped pipettes after each use of the device. The siphon shaped pipettes may be attached to the top-most part of the manifold so as to facilitate the purging of bubbles therefrom.Type: GrantFiled: April 30, 1990Date of Patent: March 23, 1993Assignee: Source Scientific SystemsInventor: John R.
