20110192790 | Water Purification Apparatus - A water purification apparatus comprising at least: (a) one or more water purification components in a housing; and (b) a handset integral with the housing, and moveable between a supported position on the housing and a suspended position beyond the housing, the handset including one or more water purification controls thereon. In this way, at least one control of the purification of the water in the housing is operative on the handset, which handset is useable either in its supported position on the housing or in its suspended position beyond the housing, whichever is most convenient to the user. More convenience is therefore provided to a user by the present invention compared with conventional purification apparatus. | 08-11-2011 |
20120103897 | Underdrain Flume Plate - An underdrain flume plate for use in a filter including at least one central opening having an upstanding flange to interface with a cut-out in an underdrain lateral to form a passageway for connecting the lateral to the flume. The flume plate may also include at least one raised channel at each end of the plate with a solid or cut-away top surface, and/or holes and/or slots for connection of the flume plate to anchor rods and may be configured to overlap one another when placed side by side. The present invention also includes a method of installing underdrain laterals in a filter, including arranging a grid of anchor rods on a filter floor such that anchor rods are provided on both sides of the flume, and providing at least one underdrain flume plate adapted for attachment to the anchor rods such that the flume plate covers the flume. | 05-03-2012 |
20130126422 | HOUSING FOR REVERSE OSMOSIS FILTER CARTRIDGE AND METHOD OF FORMING SAME - Housings for reverse osmosis filter cartridges and methods of making the same. The housings include: (1) a hollow cylindrical liner formed of a thermoplastic polymer that is adapted to surround a reverse osmosis filter cartridge; (2) a hollow head assembly that includes a transition collar portion formed of a thermoplastic polymer that is joined to said liner and a barrel portion formed of a chopped glass fiber-filled polymer that is overmolded onto said transition collar portion; (3) an end plug that is adapted to be received within an opening in the barrel portion; and (4) an overwrap layer comprising wound glass filaments and a polymeric resin that covers the outer surfaces of the liner and head assembly. | 05-23-2013 |
20130146531 | FEED SPACERS FOR SPIRAL WOUND MEMBRANE ELEMENT - A feed channel spacer for a spiral wound membrane element has inlet and outlet edges that are thinner than the rest of the spacer material. The edges may be made thinner, for example, by passing the edges of a sheet of feed spacer material through a pair of hot rollers or by compressing the edges of the sheet in a heated press. The thinned edges of the feed spacer material are located in the element between glue lines applied to the permeate spacers of the element. The thin edges allow a greater membrane surface area to be provided in a given element diameter. A feed channel spacer may also have an area with obstructions to create micro-mixing effects. These obstructions may be provided on a feed spacer sheet of constant thickness, or one with thin edges. | 06-13-2013 |
20130146532 | FEED SPACER FOR SPIRAL WOUND MEMBRANE ELEMENT - A feed channel spacer for use in a spiral wound membrane element provides a series of generally parallel interior channels. The interior channels extend from an inlet side of the spacer to an outlet side of the spacer, but follow an undulating or zigzagging path. Dean's vortices or other flow patterns that cause mixing reduce concentration polarization. The feed channel spacer is made by pressing a sheet of thermoplastic material in a die. | 06-13-2013 |
20130277301 | LAUNDER CHANNEL COVER WITH INDEPENDENTLY OPENABLE PANEL MEMBERS - A cover arrangement is provided for a launder channel of a clarifier tank. The cover arrangement includes at least one mounting section coupled to the clarifier tank near the launder channel. A plurality of cover panel members are provided, each panel member having a surface and two stiffening flanges located on opposing lateral edges of the surface, where each of the cover panel members further includes a light seal either one of attached to or attached near one of the stiffening flanges. The cover arrangement includes arranging the plurality of cover panels around the clarifier tank over the launder channel such that the light seal attached to or near the outer surface of the stiffening flange of a first panel member among the plurality of panel members abuts against a stiffening flange of an adjacent second panel member among the plurality of panel members. | 10-24-2013 |

20140231343 | COMBINED CITRUS PRESS AND ZESTER - A combined citrus press and zester. The citrus press is of a known type, and includes an upper handle and a lower handle joined at a forward pivot point. The lower handle includes a cup sized to receive a halved citrus fruit, such as a lemon or lime. The upper handle includes a male die which mates with said cup to compress and thus juice the halved fruit. To save material and weight, the male die is formed as relatively constant thickness, which results in a depression on the opposite, outer side of the upper handle. The citrus zester includes a body with a grating blade received or formed therein. The inner side of the body has a collar extending therefrom and surrounding the blade. This collar is sized to be received within the depression formed in the upper handle of the citrus press. The collar may be sized and formed such that the zester may be selectively mounted to the press. | 08-21-2014 |
