Abstract: A hydrocarbon fluid containment article having a wall with a surface that is wetted by hydrocarbon fluid. The surface includes an anti-coking coating. The anti-coking coating includes a copper salt, a silver salt, or a combination thereof. A gas turbine engine component including a wall having a first surface and an anti-coking coating on the first surface of the wall that is wetted by hydrocarbon fluid. The anti-coking coating including a copper salt, a silver salt, or a combination thereof that prevents the formation of gum or coke on a surface thereon. Methods for reducing the deposition of thermal decomposition products on a wall of an article are also provided.

Abstract: The invention provides a plurality of individually addressable radio frequency (RF) modules, any of which can be installed with any electrical device such as an ambient condition sensor or an ambient condition modifier. A prime example would be a light fixture, whether with or without a dimmable light source efficient dimming and integrated smart sensor networking related to the lighting system itself or to other systems such as parking monitors, fire alarm monitors or security alarm monitors. Independent control processing in each lighting fixture or electrical device allows a multiplicity of sensors to be locally employed and their data to control local conditions or communicate to adjoining fixtures and electrical devices and thereby control larger portions of the lighting system network or network to several unrelated systems.

Abstract: A device for enabling cables to be pulled therethrough and through a cellular floor system in which the device is adapted to be mounted, for activating a service fitting at a desired location in the floor. The device is press-fittable into aligned substantially uniform-diameter holes, formed through the slab floor, after setting of the concrete therein, and through an adjacent wall of a raceway cell in an underfloor raceway cellular deck.

Abstract: A bed comprising a mattress supporting frame supported on two pair of legs, the lower end of each pair being provided with an extendable portion so that the height of the frame above the floor may be varied, an operating shaft associated with each pair of legs, each shaft being rotatably mounted on or adjacent the associated pair of legs, an arm fixed to and projecting radially from the operating shaft, the arm being connected to the extendable portion of the legs associated with the operating shaft by one or more connecting links so that when a turning force is applied to the operating shaft to effect rotation thereof the height of each of the pair of legs associated therewith is decreased or increased and the mattress supporting frame is lowered or raised.

Abstract: A bed having a movable mattress supporting platform which is mounted upon a frame having ground engaging means in the form of legs, the mounting between the platform and frame including a plurality of operating shafts rotatably mounted to the frame; at least one arm fixed to and radially extending from each operating shaft, the arm being connected to the mattress support platform by one or more connecting links so that when a turning force is applied to the operating shaft the portion of the mattress supporting platform to which the associated connecting links are attached is raised or lowered.
