Abstract: An overflow assembly including an overflow cap and a locking ring is described that allows liquid (e.g., water) being received or collected in a plumbing fixture (e.g., a bathtub) to flow into an overflow pipe in an effective, aesthetically pleasing manner using components that are easier to install than some conventional solutions. The locking ring has a threaded inner surface that is designed to be threaded onto an externally threaded end of the overflow pipe that is extended through a wall of the plumbing fixture to secure the overflow pipe with respect to the wall. The overflow cap may then be pressed onto the externally threaded end of the overflow pipe, such that it engages the externally threaded end via engagement tabs. The overflow cap can be removed from the end of the overflow pipe by rotating the cap to unthread it from the threaded end of the overflow pipe.

Abstract: In one embodiment, a system includes a turbine engine fuel nozzle having an air path, a fuel path, and a surface along the air path. The fuel path may be directed toward the surface. The turbine engine fuel nozzle also may include a heating element configured to heat the surface.

Abstract: A kerosene combustion device includes a burner body having a heated inner surface against which kerosene and combustion air are impacted, to cause the kerosene to be vaporized prior to being ignited. The kerosene is introduced into the burner body through a pipe having an outlet configured to cause the discharging kerosene to be spirally moved and to have its velocity and pressure suddenly reduced. The pipe extends through a venturi tube which conducts the combustion air. The venturi tube includes two tapers spaced apart along its longitudinal axis to cause the air velocity to be gradually increased. The burner body includes an opening into which the venturi tube extends. That opening is formed by an inwardly projecting portion of the burner body against which the venturi tube bears, in order to be stabilized thereby.

Abstract: Combustion device of a kerosene fan heater, which can inhibit accumulation of tar inside of the carburetor and can improve a mixing efficiency of fuel of kerosene and air.The combustion device includes a spraying means for spraying flammable substance, a vaporizing means for vaporizing the sprayed flammable substance before burning the flammable substance, and a dividing means disposed in the vaporizing means for dividing the sprayed flammable substance and making the divided flammable substance swirl in opposite direction to each other.

Abstract: A liquid fuel combustor comprises a gasification promoter unit housed within a heated burner body for enhancing the gasification capability of the atomized fuel. The gasification promoter unit is provided with a downwardly convex surface. A fuel nozzle has its outlet facing toward that surface to direct fuel thereagainst. A heater is embedded in the promoter unit to heat the fuel particulates emerging from the fuel nozzle.
