A method, apparatus, and system for stopping a flow of a liquid coolant into, and drawing away a residual portion of the liquid, a portion of a cooling system, e.g., for resistance welding electrodes. The disclosed system does not require more than a single actuator, and in one case uses only a single actuator, coupled to both i) one or more liquid shutoff valves and ii) one or more liquid drawback apparatus. The liquid drawback apparatus draws on the liquid at approximately a same time that the one or more liquid shutoff valves shut off the flow of the liquid from the coolant supply. The liquid drawback apparatus includes a non-return check valve, disposed in the fluid passageway and biased against a normal flow of the liquid from the coolant supply.

A water valve, in which a water film is formed when the water valve connected to a water tank provided at a refrigerator door is opened and then closed and thus water film sealing is established downstream of an opening/closing surface of the water valve, thereby preventing dripping of water remaining in the water valve, enabling a clean use, and a refrigerator using the water valve. A valve body structure, in which a tube for guiding a flow of water toward a portion where a water film is to be formed between a nozzle and a valve is provided at the valve and an opening for releasing a water pressure even when the flow of water excessively concentrates, and thus, the water flowing through the opening may join a mainstream of the water discharged through a water passing hole.

An anti-drip device, such as for use in a faucet or water supply line, that includes a support having at least one water outlet and an elastic lip member disposed inside each water outlet. Each elastic lip member has an open state and a closed state inside the associated water outlet, and each elastic lip member is capable of switching between the open state and the closed state. When the elastic lip member is in the open state, the water outlet is open; and when the elastic lip member is in the closed state, the water outlet is closed.

In an apparatus for treating a wafer-shaped article, a spin chuck is provided for holding and rotating a wafer-shaped article. A liquid dispenser comprises a check valve positioned so as to prevent process liquid from dripping out of a discharge nozzle of the liquid dispenser. A valve seat of the check valve is at a distance in a range of 20 mm to 100 mm from an outlet opening of said discharge nozzle.

A sanitary hydrant comprises an isolated reservoir that can be positioned below a freeze level at the location of installation. A piston within the isolated reservoir is operable to expel, during a downward stroke, stored fluid from the reservoir before actuating a valve that allows fluid to flow from a fluid supply source through the hydrant. On an upward stroke, the piston releases the valve and generates a negative pressure within the reservoir that draws fluid from within the hydrant into the reservoir.

A dispensing system for dispensing cleaning product for hand sanitization comprises a cartridge having an internal reservoir for containing hand sanitization product, a nozzle configured in one of a plurality of key shapes, and a dispenser having a receptacle opening adapted to receive and engage the nozzle of the cartridge when the receptacle opening is configured in one of a plurality of key shapes corresponding to the key shape of the nozzle, the dispenser having a fluid communication passage for dispensing fluid for hand washing, whereby only cartridges and dispensers which have matched key shapes will engage each other for operative discharge of the hand wash cleaning product. The system includes a valve insert member which prevents leakage of fluid unless the nozzle key matches the receptacle opening. The valve insert member is in the form of a cup shaped member of elastomeric material, said member having a curved top having at least one slit having two slit edges, said slit defining a valve which is normally closed when the two slit edges are in mutual contact, but which slit edges separate when the curved top is penetrated, to thereby open the valve. Two slits can be provided in a cross-pattern.

A viscous food product dispensing system having a transport section for receiving a particulate food product from a bin, an auger for processing and conveying the received particulate food product from the transport section into an outlet adapter via one or more flutes, a milling device housed in the outlet adapter, and a discharge nozzle in the outlet adapter that pinches off the viscous food product created by the milling device. The auger has a unique design that allows it to engage and break whole nuts.
