  • Patent number: 12270336
    Abstract: A fan drive gear system for a turbine engine includes a sun gear that is configured to be driven by an engine shaft that is rotatable about an axis, a plurality of intermediate gears that are intermeshed with the sun gear, a ring gear assembly that is engaged with the plurality of intermediate gears, the ring gear is configured for attachment to a static structure, a carrier that supports rotation of the plurality of intermediate gears, the carrier configured for rotation about the axis, at least one baffle that is attached to the carrier that is configured to impart a momentum on expelled lubricant, a fixed gutter that is disposed radially outside the at least one baffle and is configured to receive lubricant that is exhausted from the at least one baffle, and a fan shaft that is rotatable about the axis and configured to be driven by the carrier.

  • Publication number: 20230357266
    Abstract: Provided herein are compounds, compositions, systems, and methods for photoactivatable labeling, which can be actuated within biological systems. In particular, compounds disclosed herein include vinyl-extended-aryl azide moieties that undergo photoactivation to generate reactive intermediates, which can form covalent linkages with biomolecules. The photoactivation can be conducted by a variety of mechanisms including ultraviolet (UV) irradiation, visible light irradiation, or energy transfer (e.g., from a photocatalyst). The compounds also include functional moieties that provide useful functionalities, for example detection of biomolecules, such as fluorophores, capture elements (e.g., biotin), or reactive moieties (e.g., click handles) and bifunctional moieties comprising a bioactive compound and a detection/capture element.
