Abstract: A drain plug linkage structure, comprising a pull rod assembly, a driving rod and a drain plug movably fitted in a drain pipe, the driving rod having a front end and a rear end, the front end of the driving rod being inserted from the side of the drain pipe to the drain pipe and connecting with the drain plug, the pull rod assembly comprises a connecting rod and a pull rod connected to each other, wherein one of the driving rod and the connecting rod is provided with a plurality of fixing holes, the other of the driving rod and the connecting rod is provided with a plurality of protruding fixing members, and the fixing members are detachably coupled to the fixing holes. The present invention is provided that the assembly and disassembly of the driving rod and the connecting rod of the present invention are quicker.

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.

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.

Abstract: A lavatory faucet comprises a connection pipe, a water mixing bolt seat mounted on the connection pipe, a fastening board movably located over the water mixing bolt seat, a water mixing bolt tube, a locating bolt, and a faucet neck mounted on the lavatory basin and engaged with the locating bolt and the water mixing bolt tube which is located by the fastening board pressing against the lavatory basin.

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.

Abstract: The floor drain comprises a drainage bowl (2) or outlet gutter with an upward facing inlet opening (4) and an outlet (5), comprises slots (9) or passageways having each a substantially vertical portion with a constant cross-section, and having each its entrance on a level with the inlet opening (4) and extends somewhat downwards and is adapted to be running to capacity by drainage of water from a floor.
