A handwashing valve structure includes a mounting structure, a dispensing structure, and a control structure. The mounting structure is configured to attach to a liquid vessel. The dispensing structure is configured to dispense a liquid from the liquid vessel and is movable between a closed position and an open position. The control structure is configured to move the dispensing structure between the closed position and the open position. The control structure is configured to be moved by pressure from a portion of a user's body to move the dispensing structure from the closed position to the open position. The dispensing structure is configured to automatically move from the open position to the closed position in the absence of any pressure from the portion of the user's body onto the control structure.

The present invention relates to a siphon device with a bypass, comprising: a siphon upper section having a top coupling means for connecting to a drain outlet, a side drain opening having coupling means for connecting to a wastewater utility pipe, wherein the siphon upper section is adapted to enable a direct flow via the side drain opening and thereby to bypass a basin of the siphon, thus evacuating substantial volume of accumulated water directly into the wastewater utility pipe.

Apparatus and methods to couple fuel components to a fuel tank are described. An example method includes coupling a carrier to a guide suspended in a cavity of a fuel tank, where the guide extends in a longitudinal direction between a first end of the guide adjacent a first side wall of the fuel tank and a second end of the guide adjacent a second side wall of the fuel tank opposite the first side wall, and moving the carrier along the guide between the first end of the guide and the second end of the guide.

The present invention provides a liquid supplying device and a photoresist coating equipment. The liquid supplying device i A liquid supplying device, comprising: a tank for storing liquid; and a liquid transfer pipe inserted into the tank, and an elastic retractable structure is provided on at least one portion of the liquid transfer pipe, and a pipe end portion of the liquid transfer pipe in the tank is always contacted with and pressed against an inner wall of the tank. In the present invention, the liquid is able to be output continuously, and a problem of the prior art in which the liquid stored in the tank cannot be used sufficiently can be avoided.

Diaphragm joint and convolutions, bottom screen diffuser, air stem, cap, and diaphragm restrictor systems for a pressure vessel are disclosed. A convoluted diaphragm divides the vessel into a pair of sealed chambers. The convoluted geometry of the diaphragm minimizes stress on the diaphragm at maximum displacement conditions. An H-ring, with or without being over-molded by the convoluted diaphragm, may be configured to receive end portions of the tank liners. A bottom diffuser, coupled to an inlet of the vessel, diffuses and mixes water flowing into and out of the vessel and drains water out of the vessel. Fiberglass windings surround and lock the tank liners in tension. The cap system includes a valve cap that engages an air stem. An outer cap covers a recess of the vessel and includes a hollow cavity that receives the valve cap. A diaphragm restrictor limits upward movement of the diaphragm within the vessel.
