  • Patent number: 12055286
    Abstract: A light fixture mount including a base, a housing, a sled, and a latch rotatably coupled to the housing. The base defines an opening extending through the base. The housing is positioned on the base and defines a compartment, wherein an access opening is provided in the housing for access to the compartment. The sled is configured to be positioned at least partially within the compartment and includes a sled base configured to support a component for a light engine and a faceplate configured to cover the access opening of the housing. The latch is configured to rotate between a locked configuration and an unlocked configuration, wherein the latch engages and secures the sled to the housing.

  • Patent number: 12055284
    Abstract: An optical assembly includes a retention ring configured to couple an optic and a trim. The optic can receive light from a light source and include an optic coupler. The trim can surround the optic and direct the light away from the light source. The trim can include a trim coupler. The retention ring can tool-lessly couple with the optic and the trim. The retention ring can include an optic retention element configured to tool-lessly couple with the optic coupler to couple the optic to the retention ring; and a trim retention element spaced radially outwardly from the optic retention element. The trim retention element can tool-lessly couple with the trim coupler to couple the trim to the retention ring radially outwardly from the optic.

  • Patent number: 10829181
    Abstract: A multihull sailing vessel includes at least two buoyant hulls extending along their longitudinal axes, with the hulls being connected to each other and a first hydrofoil connected to the hulls and oriented transverse to the hulls. The first hydrofoil is movably coupled to the hulls between a first position above a resting waterline of the hulls and a second position below a lowest extent of the hulls. When the first hydrofoil is in the second position, a configuration of the first hydrofoil is adjustable to vary an amount of lifting force generated by the first hydrofoil when the hulls move forward through water when the first hydrofoil is in the second position.

  • Patent number: 10247393
    Abstract: A recessed lighting unit includes a light engine and provides angular adjustment of the light emanating from the lighting unit. In one arrangement, the lighting unit includes a heat sink and a module frame that slidingly interact to provide rotation of the light engine in one degree of freedom, for example rotation about a horizontal axis. A rotation mechanism may also be provided for rotating the light engine in a second degree of freedom, for example rotation about the axis of a cylindrical recessed can in which the light engine is disposed. The lighting unit may be configured for use in new construction, or for retrofit applications.

  • Patent number: 7682207
    Abstract: An electrical contact carrier strip includes a main body, a plurality of electrical contacts integrally formed with and connected to the main body, and a plurality of support tabs extending from the main body. Each of the support tabs includes a stem connected to the main body and a free expanded base that is aligned with and wider than the stem. The support tabs provide a clearance gap in which at least portions of the plurality of electrical contacts reside. The plurality of support tabs support the portions of the plurality of electrical contacts over a plane in which distal ends of each of the free expanded bases of the support tabs reside.

  • Patent number: 5622790
    Abstract: A molten carbonate high temperature fuel cell contains a hydrocarbon-containing fuel reforming catalyst on a support, where the catalyst is produced by reducing a catalyst precursor which is prepared by intimately mixing a defined Feitnecht compound with a non-calcined alumino-silicate clay mineral and at the same time and/or subsequently but prior to calcination with at least one added stabilizing additive for reducing silicon-species loss selected from the group consisting of alkaline earth metal compounds, rare earth metal compounds and mixtures thereof, and, optionally, an alkali metal compound, and thereafter calcining the intimate mixture, wherein the catalyst has been found to be suitable for the steam reforming of methane at the working temperature of the molten carbonate fuel cell and has been found to be substantially resistant to deactivation in the hot alkali metal carbonate environment.

  • Patent number: 4812120
    Abstract: A prosthetic dental device, adapted for percutaneous implantation, consists of a metal core that is directly coated with a first layer of polymer, and is overcoated with a second polymeric layer in which fibrils of a biopolymer are embedded and secured. The fibril nap provides a framework for the growth and attachment of regenerating recipient connective tissue, and also serves as a barrier against epithelial invasion, which would otherwise tend to cause implant rejection.
