A water filler includes a water filling device, and a regulating device. The water filling device includes an inner filling tube, an outer filling tube, and an upper cover. The regulating device includes a floating barrel, a sliding barrel, a water support disk, and an adjusting unit. Thus, the floating barrel is lifted instantaneously and rapidly to stop the water filling action exactly and actually, thereby saving the water source. Thus, the water filler has a quick water stop function.

A water turbine or pump having a rotor (1) and a stator (2). The leading edges (13) and the trailing edges (14) at least of the rotor blades (6) form a bend (15) projecting in opposite relationship to the flow direction (12). That causes a flow force resulting in a self-cleaning effect being applied to impurities which are deposited at the leading edges (13). However the adjustment design providing for adjustability of the rotor blades remains substantially unchanged.

A water closet has a flush tank which reduces the head of flush water presented to a downwardly converging bowl which receives waste to be discharged through an outlet to a siphon trap, the bowl having a rim which causes the flush water to be presented to the trap in a vortex fashion. The trap is U-shaped and includes an upleg and downleg, the upleg having a converging-diverging cross-section to cause the dischrge to be pushed quickly from the bowl into the downleg, which becomes filled and crea...

A water bag for a water bed, including a hollow shell dividing into two inflating chambers at two oposite ends and a plurality of transverse water chambers between the inflating chambers, and a plurality of air bags longitudinally mounted in the transverse water chambers in parallel and respectively connected between the inflating chambers.

A water purifier using common advantages of natural and forced types operated without an external electric power source, resulting in high efficiency of water purification. The apparatus for purifying water includes a first water-supply pipe for transporting running water with a predetermined pressure, a second water-supply pipe for pumping the running water to the highest position of the apparatus, a first purifying section for temporarily storing and purifying the water provided by the second ...

Water-in-oil-in-water multiple emulsion compositions are disclosed. The multiple emulsion compositions comprise an external aqueous phase optionally incorporating a surfactant system capable of forming liquid crystals as an emulsifier. The internal phase comprises a primary water-in-oil emulsion, wherein the primary emulsion comprises a first topically-active compound, a surfactant phase, an oil phase, and water.

A water purifier includes a base, an outer casing mounted on the base, a fresh water conduit demountably mounted in the outer casing, a plurality of filtering units demountably mounted on the fresh water conduit and a cover demountably mounted on the outer casing. Each filtering unit includes a membrane bag and multiple supporting members. The membrane bags are sandwiched by the supporting members and are arranged in a cascading manner. Gaps are formed between each pair of adjacent membrane bags...

A small outboard motor powered boat comprises a hull undersurface that defines a generally flat central section, with two generally parallel-sided pontoons extending rearwardly from an upturned bow to a point about half the length of the hull aft. A stern rake section begins at a transverse line near the transom of the hull and forms a downward angle with respect to the flat central section. At speed, air is entrained between the pontoons, providing lift to the bow of the vessel, while the after...

Mineral particles consisting essentially of metallic magnesium particles subjected to special processing are accommodated directly in a microporous cartridge made of a sintered polypropylene material, and the cartridge is closed. The cartridge is put in a closed raw water container, whereby a large amount of hydrogen gas is generated in a short period of time and released from the whole surface of the cartridge in the form of microbubbles so as to be dissolved in raw water in the container.

A multiple emulsion of the type W.sub.1 /O/W.sub.2 is made by first preparing a primary emulsion W.sub.1 /O using a silicone fluid as the oil phase (O), and an elastomeric silicone polyether as an emulsifier, for dispersing water phase W.sub.1 into oil phase (O). The primary emulsion W.sub.1 /O is then added and dispersed into a final continuous water phase W.sub.2 to form a multiple emulsion W.sub.1 /O/W.sub.2. The multiple emulsions are useful for treating the hair, the skin, or the underarm a...
