  • Patent number: 11970974
    Abstract: A gas turbine engine and engine mount structure includes a core engine including a compressor section, a combustor section and a turbine section mounted within a core engine housing. The fan, the compressor section and the turbine section rotate about an axis of rotation. An outer nacelle surrounds the fan, and is spaced from the core engine housing to define a bypass duct. The fan delivers air into the bypass duct and into the core engine housing. The nacelle is formed with camber so as to be curved in a first plane away from the axis of rotation in a first lateral direction. An engine mount structure extends from the nacelle at an angle that is non-parallel and non-perpendicular to the first plane, and has a component in a lateral direction that is opposed to the first lateral direction. An aircraft is also disclosed.

  • Patent number: 11713734
    Abstract: A multi-function fuel delivery system and method of providing fuel delivery is provided that addresses space-related and cost related challenges as well as other challenges by combining a noise attenuating function, a hydrogen heating function, and a fuel supply rail capable of supplying hydrogen to multiple injectors within a single volume where a heat-transfer core utilizes an existing available internal volume of an attenuating volume or a fuel rail of a hydrogen supply manifold. A hydrogen fuel manifold, a hydrogen heat exchanger, and a fuel rail are housed in a single chamber such that a hydrogen fuel heating/cooling function, a hydrogen fuel noise/vibration attenuating function, providing the heat to the heat-transfer core, and providing the noise-attenuated H2 are performed in the single chamber.

  • Patent number: 11577655
    Abstract: A flexible shelf guard for securing items or products in a shelf of a recreational vehicle is disclosed. The shelf guard is designed with a first section and a second section. The first section and the second section are molded to a middle section using a two-shot molding process, thereby producing the shelf guard. The shelf guard is securely and removably affixed to a top portion of the shelf by inwardly folding both end portions of the first section and the second section. The shelf guard comprises a holder and a drainer. The holder is molded to a front portion of the middle section of the shelf guard using any molding process. The drainer is configured to drain fluid/water within the shelf, thereby preventing the growth of molds and microorganisms by maintaining a dry environment within the shelf.

  • Publication number: 20200088284
    Abstract: A gear assembly rotates about a pin in an actuator. The gear assembly includes a gear. The gear includes a gear body including a first polymer surrounding and extending radially away from a rotational axis. The gear body has an internal surface that defines a bore along and about the rotational axis. The gear further includes a plurality of teeth extending from the gear body. The gear assembly further includes a bushing including a second polymer, different than the first polymer. The bushing is disposed within the bore. One of the bushing and the gear body is overmolded to the other one of the bushing and the gear body along the internal surface. The bushing has a bearing surface defining a hole along and about the rotational axis for rotatably engaging the bearing surface with the pin in the hole.

  • Publication number: 20160009749
    Abstract: The present invention provides methods to treat mixtures containing natural rebaudioside A (Reb A), rebaudioside B (Reb B), and rebaudioside D (Reb D), synthetic counterparts of these, and/or derivatives of the natural or synthetic embodiments obtain one or more of these glycosides in more pure form. In many embodiments, the invention can be used to process glycoside mixtures obtained at least in part from natural sources such as the Stevia plant. This allows, for instance, the recovery of a product including Reb A material in more pure form relative to Reb B material or Reb D material. As an alternative or in addition to recovery of the purified Reb A material, a product including Reb B material and/or Reb D material in more pure form relative to Reb A material can be obtained.

  • Publication number: 20070105190
    Abstract: A process for hydrolyzing products with enzymatic activity remaining in peptone solutions after mucosa hydrolysis is provided along with a process for preserving mucosa tissue. Broadly, the processes are carried out by hydrolyzing mucosa tissue according to conventional heparin manufacturing processes wherein an excess quantity of proteolytic enzymes is used. The resulting peptone solution is then contacted with proteins or protein-containing materials in order to hydrolyze the proteins. In another embodiment, mucosa tissue is preserved by mixing it with a preserving agent selected from the group consisting of hydrogen peroxide and phosphoric acid. The product preserved by hydrogen peroxide is low in ash, stable for at least a week, and has a reduced odor.

  • Publication number: 20050154288
    Abstract: A method and apparatus for retrieving, accessing, and storing medical data relating to a patient during a medical procedure. The invention provides a single interface to many disparate forms of medical data, which is accessible over a local area network; wide area network, direct connection, or combinations thereof. In one embodiment, an operating room control system for use during a medical procedure on a patient includes an input device, a display device, and a controller that is coupled to the input device and the display device. The controller receives one or more user inputs, transmits a command to a server located outside of the operating room to retrieve medical data, receives the medical data from the server, and displays the medical data on the display device. Medical data can be captured by the controller using, for example, a camera and a video/image capture board, keyboard, and microphone during surgery or examination of the patient.
