Abstract: Sink stations for galleys of aircraft and other vehicles, methods of operating such sink stations, and aircraft equipped with galleys having such sink stations. A sink station includes a sink cover, which may fully or partially cover a sink and extend the countertop space over the sink cavity. When covering the sink, the sink cover may support a set weight corresponding to objects typically used in galleys, such as pots, cups, and the like. The sink cover allows for liquid to pass into the sink cavity even when the sink cover is used to cover the sink thereby reduce spill clean-ups. The sink cover is movable and may partially or completely expose the sink cavity or keep it completely covered. For example, the sink cover may be folded and/or rolled away and stored at the sink station for periodic use.

Abstract: An in-line water trap located in the line of the flow of waste through a generally straight line or bend is provided for. Typically, the water trap comprises a fluid conduit having a first end, a second end and a passage between the first and second ends; and a vessel having a closed end, an open end and a skirt between the closed and open ends, the lobed vessel further having an inner surface defining an inner volume and an outer surface, the inner surface attachingly engaging an outer wall of the fluid conduit in so doing defining a flow path between the passage, the inner volume of the lobed vessel and the outer surface of the lobed vessel, in use, a fluid level inside the inner volume of the lobed vessel being substantially in communication with the second end of the fluid conduit to form a fluid seal.

Abstract: An improved method and apparatus to prevent clogging of condensate drain lines with a biocide delivery system that prevents the growth of bioorganic growth in the liquid trap using time release biocide tablets or liquid biocide. When using solid biocide tablets erosion and dissolution of the tables is reduced. When using liquid biocides, combination of initial release followed by gradual release of residual liquid biocide in the drain water is attainable. Drain line are promoted from clogging while being installed anywhere on the drain line upstream of the liquid trap. The apparatus can also be incorporated with a liquid trap, allowing placement anywhere in the drain line.

Abstract: A valve apparatus includes a housing, which defines an interior chamber, a baffle disposed in the interior chamber, and a volume of liquid. The housing includes first, second and third portions. The first portion includes first and second ports that communicate with the interior chamber. The second portion is spaced from the first portion along a longitudinal axis. And the third portion extends along the longitudinal axis between the first and second portions. The baffle at least partially defines a helical fluid flow path between the first and second ports, and the volume of the liquid is disposed in the second portion of the housing.

Abstract: Improvements in retention of the oily liquid sealant (20) in a oil-sealed odor trap (10B-10M), for drain applications such as a waterless urinal or anti-evaporation floor drain, are accomplished by minimizing turbulence in the oil sealant, such as by making the liquid flow path (22A, 22B) substantially horizontal as a departure from conventional practice of substantially vertical flow and by positioning a barrier (40) above the oil sealant to prevent direct impingement of urine or other waste products onto the sealant. The trap is thus structured to realize the substantially horizontal liquid flow path and to locate the flow path immediately beneath the sealant layer or beneath a baffle portion (16B). The baffle portion may be sloped such that stray sealant droplets are encouraged to migrate upwardly to the upper surface of the flow path due to their buoyancy and, therefore, the stray droplets will be recaptured and returned to the main sealant layer.

Abstract: A water trap comprising a cylindrical outer casing having a flat top wall and a frustoconical bottom wall, an internal substantially semi-circular open topped water seal container within the outer casing, an inlet into the water seal container which passes through the top wall and abuts one side wall of the water seal container and extends thereinto, and an outlet from the bottom wall of the trap that is offset from, and co-linear with, the inlet. The cross-sectional areas within the trap progressively increase to promote water flow through the trap.

Abstract: Sewerage inlet having a grating (3), a foliage-retaining basin (4) arranged below said grating (3) and a container provided with an outflow pipe (6) in which container a valve (10) controlled by a float is arranged upstream of the outflow pipe (6) and closes said outflow pipe (6) when the liquid in the container is lighter than water. For conveying the surface water away from streets, grounds and production yards a sewerage inlet is proposed, the container (5) thereof being subdivided by a removable separating floor (11) into an upper sedimentation chamber (12) and a lower collection chamber (13) into which the outflow inlet (8) connected with said outflow pipe (6) having a valve (10) and a float are arranged and whereby said sedimentation chamber (12) is connected via a soil pipe (14) with said collection chamber (13), the inlet opening (15) thereof being at a relatively large distance from said separating floor (11) and the outlet opening (16) being below said outflow pipe (6).
