Abstract: A system and method for extracting active elemental iodine from the contact of water with stored crystal iodine and for introducing the extracted elemental iodine into a water supply line and/or otherwise making the extracted elemental iodine available for an intended use. The system operates by allowing a portion of the water entering from a water supply line to be redirected to a first housing where it makes contact with stored crystal iodine causing to extract active elemental iodine. The iodinized water leaves the first housing and enters a second housing where it makes contact additional stored crystal iodine to help stabilize the elemental iodine concentration. The system can be designed to provide the elemental iodine in more than one potency concentration through the use of a metering valve and different travel routes for the elemental iodine out of the second housing.

Abstract: A movable fuel valve lies within a housing at an end of a housing fuel passage. A fuel tube has a nozzle end inserted within a first end of the housing fuel passage while the movable valve element is situated at a second end of the housing fuel passage and controls fuel flow from the second end of the housing fuel passage. The nozzle end remains surrounded in fuel when the valve element is closed and sealed against the second end of the housing fuel passage.

The movable valve element prevents fuel from flowing from the main-side of a fuel tank to the sub side of the tank.

Abstract: A liquid handling system transfers liquid (e.g. water, bearing marine animals) between two tanks each having a respective liner which is movable between a lining position (when filled with liquid) and an inverted position (when its respective tank is emptied). In an initial state, liquid is held in a first tank. By supplying air to a space between the first tank and its liner, its liner is progressively lifted and liquid passes along a channel onto the initially inverted second liner (which acts as a baffle to slow the liquid flow). Air in a space between the second liner and the second tank is vented so transferred liquid sinks the second liner to fill the second tank. A ballast liquid may be used in the spaces. Initially held in the second tank, the ballast liquid flows via a passage into the first tank as transfer of liquid progresses.

Abstract: A fuel feed apparatus including a sub-tank is received in a fuel tank having multiple tank sections. Multiple jet pumps respectively transfers fuel received in the tank sections into the sub-tank. Therefore, even if a fuel amount received in a single tank section decreases, fuel can be steadily supplied from another tank section.

Fuel is drawn from an upstream side of a pressure regulator, and supplied to the jet pump. The pressure regulator has an urging unit, and controls fuel pressure without using a diaphragm. Therefore, the pressure regulator is simplified and downsized.
