Supply Outlet And Drain Patents (Class 4/673)
  • Patent number: 8950690
    Abstract: An anti entrapment fail safe drain having a drain cover for partially covering an influent opening; a pressurized supply line; and a nozzle assembly in communication with the pressurized supply line and mounted within a drain sump. The nozzle assembly is for directing a pressurized liquid in a pattern over a surface of the drain cover when the drain cover and the nozzle are immersed in the liquid such that a portion of the liquid above the pattern or objects suspended in standing liquid can not be pulled directly toward the drain cover through a drain inlet opening. The drain also has an effluent opening for connecting to the drain sump arranged such that the liquid flows into a pipe in a first direction. The pressurized supply line is arranged inside the pipe for returning the liquid to the nozzle assembly in a second direction opposite the first direction.

  • Patent number: 8898828
    Abstract: Food preparation sinks are disclosed which have an integral raised work area that is rinsed by an automatic system. Food waste or the like present in that area can be washed into a sump above a drain, and the weight of the waste and water in the sump is enough to automatically drive them through a baffle to a garbage disposal, without requiring the baffle to be manually opened. An automatic controller system coordinates water flow and garbage disposal operation, and the water supply can be linked to the sink below the sink rim to save counter top space. In some forms multiple rinsing nozzles are provided which pulse in altering fashion.

  • Patent number: 6484329
    Abstract: A stopper for selectively blocking a drain to the passage of water. The drain has an inlet, an outlet and a substantially cylindrical throat between the inlet and outlet. A control means is provided for selectively feeding control fluid under hydraulic pressure to the cylindrical throat whereupon an expandable bladder located within the cylindrical throat selectively expands in fluid communication with the control fluid to block the drain and thus act as a stopper.
