  • 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: 11083347
    Abstract: A reversible toilet paper roll holder. The reversible toilet paper roll holder has a base with an arm extending through the base. The arm is rotatably secured to a locking notch that enables a user to lock the device in a pair of orientations. A horizontal support is connected to a distal end of the arm, and a pair of lateral supports are each connected to the horizontal support. In one embodiment, a pair of lateral supports can secure a toilet paper roll therebetween, while in other embodiments, the pair of lateral supports can secure a compressible rod therebetween. The compressible rod can be threaded through a central bore of a roll of toilet paper. The orientation of the arm can be rotated to reverse the direction at which toilet paper is dispensed by rotating the toilet paper roll without removing the toilet paper roll from the device.

  • Patent number: 10677874
    Abstract: A system and method is provided to acquire images of a subject having received a tissue soluble hyperpolarized gas into the airways. The method includes performing a pulse sequence including (i) for each effective repetition time (TReff), acquiring at least one gas-phase dataset and at least one dissolved-phase dataset, wherein a gas-phase echo time (TEGas) of the at least one gas-phase dataset and a dissolved-phase echo time (TEDissolved) of the at least one dissolved-phase dataset are selected to isolate gas-phase contamination of the dissolved-phase dataset from dissolved-phase components in the dissolved-phase dataset.

  • Patent number: 6926928
    Abstract: A gas turbine component, such as a turbine disk or a turbine seal element, is protected by depositing an oxide coating on the gas turbine component. The deposition is performed by a vapor deposition process such as metal-organic chemical vapor deposition (MOCVD) to a coating thickness of from about 0.2 to about 50 micrometers, preferably from about 0.5 to about 3 micrometers. The deposited oxide may be an oxide of aluminum, silicon, tantalum, titanium, and chromium.

  • Patent number: 6616978
    Abstract: A substrate is protected by a multilayer protective coating having an oxide layer, and a phosphate/organic binder layer initially overlying the oxide layer. The multilayer protective coating is cured by first degassing the multilayer protective coating in a pre-cure degassing temperature range of from about 250° F. to about 500° F. for a time of at least about 30 minutes. The multilayer protective coating is thereafter heated to a curing temperature range of from about 1200° F. to about 1400° F. for a time of at least about 30 minutes.

  • Patent number: 6256809
    Abstract: There is disclosed a waste prevention system which avoids the discharge, inadvertent or otherwise, of laboratory waste, into a public sewage system and subsequently into the natural environment. The system employs, in combination, a laboratory sink having cooperatively connect thereto a carboy for collecting pollutants. The carboy is provided with elements to permit removal of samples of materials delivered thereto from the sink for testing of the same to determine the presence of pollutants. In the event no pollutants are present, the carboy may simply be opened and any wash or rinse water from the sink can be delivered into a public sewage system and then to the environment.
