Abstract:
The invention provides a skin-care liquid preparing unit comprising: a main container 2 which contains raw water; a cartridge container 3 which is placed in the main container 2, and which contains different kinds of cation exchange resins; and a sprayer 4 which is attached to an upper end mouth portion 6 of the main container 2, and which has a suction pipe 17 connected to an upper portion of the cartridge container 3. The unit is configured so as to pass the raw water in the main container 2 through the cartridge container 3 from a lower portion of the cartridge container and spray the water from the sprayer 4. In the unit, in order to easily prepare skin-care liquid of a pH value that is useful for moisture retention and health of the skin, an Na type or K type cation exchange resin layer 13 and an H type cation exchange resin layer 11 are formed to be arranged in upper and lower positions in the cartridge container 3.
Abstract:
The invention is directed to purification of liquids, such as drinking water using filters, wherein filtration is effected while the liquid flows upwardly. The invention includes both the method and a device enabling the method to be carried out. The device is constructed to intake impure liquid at the bottom of the filter and initially to effect flow by filling liquid to above the filter outlet near the top, and maintaining flow thereafter by virtue of the presence of a low internal pressure that develops as the liquid passes through the system.
Abstract:
A shower device having a water purifying function includes a cartridge type filter formed with a water inlet at one end and a water outlet at the other end and means for showering such as a shower head connected to the water outlet of the cartridge type filter. The cartridge type filter contains a tannin layer consisting of a material comprising tannin, a bakuhanseki layer consisting of granular bakuhanseki formed in a layer, a ceramic layer consisting of granular ceramic formed in a layer, a magnetite layer consisting of broken pieces of magnetite formed in a layer and provided at least on the water inlet side or on the water outlet side of the ceramic layer, and magnetizing means such as magnets for magnetizing the magnetite layer.
Abstract:
A portable, manually-operated water filtration pump for purifying water. The pump includes an inexpensive, disposable filter cartridge which can be easily changed when the filter elements are no longer effective. The pump uses a lever to actuate a double-acting piston. The lever is collapsible to one side of the pump for compact storage. The filter cartridge is a tubular cylinder having an inner bore forming the pump cylinder. A cylindrical mechanical filter is concentric with and adjacent to the inner bore to filter out particulates larger than 0.3 microns. A fluidized granual activated carbon filter surrounds the mechanical filter to absorb halogen and halogen-related compounds such as herbicides and pesticides. The pump pumps filtered water into a bottle adaptor which will fit most standard water containers. A prefilter is provided to screen out large particulates from the pump to enhance the life of the filter elements. The prefilter is shaped such that it will sink in water sources and to keep the prefilter inlet substantially upright in still water and tilted from horizontal in moving water.
Abstract:
A cartridge (1) for mounting in a water circuit of an apparatus (3) comprises a chamber (6) having a first orifice (4) connected to a liquid reservoir, and a second orifice (5) through which the liquid exits. The chamber also contains a resin (8) for demineralizing the liquid, as well as a state-changing material indicating saturation of the said resin, the chamber having a transparent portion (7) permitting a user to verify a color change. The transparent portion (7) comprises two juxtaposed windows (9 and 10) and a separating partition (11) arranged between the first orifice (4) and the second orifice (5), one end of which terminates at the transparent portion (7) between the two windows (9 and 10) and the other free end of which separated from the peripheral wall delimits, for the liquid, a path of predetermined length so as to permit comparison between the two windows.
Abstract:
The present invention relates to an ion exchange device for purifying water by reducing the nitrite and/or nitrate content, consisting of at least one container with a basic anion exchanger in chloride and/or sulphate form arranged therein and at least one additional basic anion exchanger layer in hydroxyl form or a hydroxyl-group-containing layer, in which the anion exchanger layers are arranged one behind the other directly and/or with the interposition of an intermediate layer and the anion exchange layer(s) in chloride and/or sulphate form is/are arranged not as a mixture but in (a) separate layer(s). The chloride and/or sulphate containing layer is arranged near or beneath the inlet aperture, preferably beneath the filter layer and/or (in the direction of flow of the water) in front of the anion exchange layer in the form of hydroxyl or containing hydroxyl groups. This invention also relates to processes for manufacturing and for using the ion exchange device to remove nitrates and/or nitrates from water.
Abstract:
A water treatment system and related components for reducing contaminants in normal drinking water are provided. An elongated tube has first and second ends and is connected with an interference fit at its first end to the interior surface of a neck of a conventional bottle. Water treatment media is disposed within the tube adjacent its second end, such as activated charcoal, halogenated resins, ion exchange resins, calcium and/or magnesium leaching material. The tube includes a flange adjacent its first end which minimizes the possibility that water will enter the bottle except by flowing through the open first end of the tube. A cap is provided for disposition over the tube, a lower portion of the cap sealing the open first end of the tube to prevent water from flowing through it, and apertured substantially 360 degrees around its circumference to allow free flow of water from the bottle which has already been treated by the treatment media when an upper portion of said cap is moved axially relative to the lower portion from a closed to an open position. A replaceable filter cartridge is also provided for attachment to the lower end of the tube, the cartridge containing any one or more of filter media, flavoring concentrates and/or minerals or vitamin supplements. An adaptor is also provided for converting a snap-on cap bottle neck to a screw-on cap bottle neck so that a screw-on type cap may be utilized with either type bottle neck.
Abstract:
A composite cartridge-type filter effective to substantially reduce low but hazardous concentrations of lead in drinking water to acceptable levels utilizes a porous activated carbon block filter and a powdered deionizing resin which is converted to an ion exchange resin in situ and during use of the filter. The method of operation of the filter results in a substantially extended life for lead removal as compared to similar disposable cartridge filters. The composite filter is also affective in removing dissolved metals which are leached from the soluble ash fraction of the carbon block itself. Powdered deionizing resin, having a greatly enhanced active surface area as compared to the resin beads from which it is formed, is formed by fracturing the resin beads in situ in a slurry filling and drying process which provides a stable packed resin bed.
Abstract:
Apparatus for filtering radioactive contamination from a contaminated medium by leaching the contamination from the medium into a liquid and removing the radioactivity from solution by passing it through an ion exchange resin. The apparatus includes a container having a base and side wall, a filter cartridge disposable on the base of the container and a basket having a wall through which fluid held in the container flows. The basket is disposable adjacent the cartridge in the container. The cartridge has a central cavity bounded by a first filter wall and a second filter wall spaced outwardly from the first filter wall, with the two filter walls having a selected mesh size to capture the contaminated medium. A first and second barrier extend in spaced relation to one another and between the first and second filter walls to define a filter medium enclosure surrounding the central cavity. A magnetic stirrer is used to induce liquid flow in the container, including flow through the cartridge and basket.

Receivers with a detachable seal comprising a porous compressive mass (4) substantially covering the whole base of the receiver are suitable for purifying liquids, particularly photographic processing baths.
