Abstract: A lavatory drain system is disclosed. The basin, containing a U-shaped drain channel, employs one of two draining embodiments. In the first, a drain plate divides the drain channel into two chambers, allowing for fluid communication between them through openings in the drain plate. In another embodiment, the drain channel forms the upper chamber while a pipe disposed below the channel serves as a lower chamber for fluid to flow to the drain. Further, the drain cap of the claimed system is configured to direct air about the basin. One embodiment utilizes a ridge protruding over one of the basin's sides to captures air and directs it to a return duct. In the other embodiment, a series of louvres located in an opening are used to filter water and debris from the air before it returns to the fan.

Abstract: A wash basin, as for a domestic bathroom, has normal inlet water faucet(s) and spigot(s) fitted at or above its top and a normal outlet or drain pipe at its bottom. The basin also has a peripheral inlet flow channel formed below its top rim, for creating a smoothly-flowing film of water cascading down the interior sides of the basin to the outlet. This flowing water film intercepts detritus such as shaving cream, toothpaste, and soap, preventing it from sticking to and soiling the interior of the basin. The basin preferably also has a peripheral overflow channel formed in its side wall adjacent but spaced from the peripheral inlet channel and communicating to the drain below any drain plug or stopper that may be used. The inlet flow channel preferably has a separate water supply and control so that it may be used either separately from or in addition to the regular water supply and so that it may alternatively be left off even while the regular water faucet(s) and spigot(s) are in use.

Abstract: A method and apparatus for evacuation of liquids, such as wastewater from e.g. wash basins, urinals, bath tubs or showers, whereby the liquid is collected in a sump, generates a hydrostatic pressure and is evacuated from the sump through a vacuum pipeline after a predetermined hydrostatic pressure is generated. In order to avoid flexible control conduits and to achieve time controlled evacuation with a simple mechanism, valves are integrated in a housing and operated by pressure differences acting on diaphragms after a certain hydrostatic pressure has been generated. One of the valves opens a connection between the sump and the vacuum pipeline to evacuate the liquid.

Abstract: To provide for positive sanitary separation of water spilling or overflowing from a washing sink unit (1), a cleaning sink unit (2) and a third water receiving unit (3), which may be formed as a sink unit or as a drain board, the second unit, located between the first and the third, is surrounded by a raised zone which merges with a forward region of a water retention rim (4) surrounding all the sink units, the raised region (5) terminating short of the rear edge region (19) of the sink unit, and leaving with the water retention rim (4) adjacent the rear edge region a gap (7). A drain and overflow opening (8) is located in the gap. Surfaces of the sink which may be essentially planar are pitched towards the overflow and drain opening, so that any water splashing or overflowing from any one of the three units or regions (1, 2, 3) will drain off into the overflow without flowing back into another one of the units or regions.

Abstract: A device is provided for removing and containing debris present in a fluid as the fluid moves through the device. The device includes a cover member attachable to an inlet pipe for receiving the fluid-carrying debris and an outlet pipe for removing the debris-less fluid. A receptacle is removably secured to the cover member while a replaceable trap bag is housed therein to contain the debris that is deposited by the fluid. The trap bag has a longitudinal seal portion which includes a flat seal portion to overlie a portion of the rim of the receptacle. A gasket member underlies the cover member to engage that portion of the trap bag which overlies the receptacle rim, including the flat seal portion. The flat seal portion substantially eliminates leakage of fluid along the longitudinal seal portion of the trap bag since there is virtually no difference in width between the flat seal portion and other portions of the trap bag overlying the rim.
