Patent application number | Description | Published |
20100101010 | CHLORINATOR FOR PORTABLE SPAS - An oxidizer generating apparatus having a housing with a fluid inlet at a first end, the inlet leading to a chamber, and a lid attachable to a second end of the housing for closing the chamber. First and second pairs of electrodes are attached to the lid so as to suspend them within the chamber in position to generate chlorine and/or other oxidants from fluid pumped through the housing. | 04-29-2010 |
20100294724 | SPA CALCIUM REMOVAL METHODS AND APPARATUS - Strong acid cation resins used alone or in combination with zeolite-based ion exchange resins are encapsulated in various water permeable polymer fabric bags of various geometries and thicknesses to reduce the calcium hardness levels during swimming pool and spa water fills. The resin bags are strategically placed in the pool or spa to allow water under pressure to flow through the ion exchange media to exchange calcium or magnesium ions with sodium or other harmless cations. | 11-25-2010 |
20110010835 | Drop-In Chlorinator For Portable Spas - An oxidizer generating apparatus comprising a cylindrical housing and an electrode assembly attached at one end of the housing comprising at least three vertically disposed electrodes, the electrodes being spaced apart so as to define a water flow path between them, the electrodes comprising titanium outer electrodes and at least one inner diamond electrode | 01-20-2011 |
20110062065 | EXCHANGEABLE MEDIA FILTER - A filter element for a pool or spa including a sintered plastic outer cylinder of a first diameter, a sintered plastic inner cylinder of a second diameter less than said first diameter; the inner cylinder being position coaxially with respect to the outer cylinder to define an annular interior chamber; and a selected granulated filter medium or combination of media residing in the annular interior chamber. | 03-17-2011 |
20110062066 | Exchangeable Media Filter - A filter element for a pool or spa including a sintered plastic outer cylinder of a first diameter, a sintered plastic inner cylinder of a second diameter less than said first diameter; the inner cylinder being position coaxially with respect to the outer cylinder to define an annular interior chamber; and a selected granulated filter medium or combination of media residing in the annular interior chamber. | 03-17-2011 |
20110120925 | Exchangeable Media Filter - A filter element for positioning in a filter compartment of a spa includes a plastic mesh outer cylinder and a plastic mesh inner cylinder, the inner cylinder being positioned coaxially with respect to the outer cylinder to define an annular interior chamber with a filter element of annular cross-section disposed in the chamber and having keyed landings formed on the top and bottom thereof, which respectively mate and interlock with one or more keyed landings on top and bottom caps of the filter element. The apparatus may further include a plurality of vertically disposed mesh compartments interlinked in a ring and disposed within the filter element, the compartments being filled with a selected filter medium or filter media. | 05-26-2011 |
20110253637 | SPA WATER SANITIZING SYSTEM - A method of sanitizing water contained in a spa is provided which comprises installing a chlorine generating cell including a diamond electrode in a filter compartment of the spa, employing a resin-filled calcium remover bag to reduce the hardness of the water, adding salt to the water; and operating the chlorine generating cell to generate chlorine and other sanitizing agents for sanitizing the water. | 10-20-2011 |
20110253639 | Spa Water Sanitizing Method and Apparatus - A spa sanitizing apparatus including a sanitizing agent generating cell, an H-Bridge circuit arranged to supply a voltage to electrodes of the cell, a controller circuit for controlling the operation of the H-Bridge circuit, and a watch dog circuit for monitoring a voltage applied to the electrodes and for shutting down power if the voltage departs from a pre-determined limit. | 10-20-2011 |
20120103918 | Chlorinator For Portable Spas - An oxidizer generating apparatus having a housing with a fluid inlet at a first end, the inlet leading to a chamber, and a lid attachable to a second end of the housing for closing the chamber. First and second pairs of electrodes are attached to the lid so as to suspend them within the chamber in position to generate chlorine and/or other oxidants from fluid pumped through the housing. | 05-03-2012 |
20120298589 | Drop-In Chlorinator For Portable Spas - An oxidizer generating apparatus comprising a cylindrical housing and an electrode assembly attached at one end of the housing comprising at least three vertically disposed electrodes, the electrodes being spaced apart so as to define a water flow path between them, the electrodes comprising titanium outer electrodes and at least one inner diamond electrode | 11-29-2012 |
20140231248 | Drop-In Chlorinator For Portable Spas - An oxidizer generating apparatus comprising a cylindrical housing and an electrode assembly attached at one end of the housing comprising at least three vertically disposed electrodes, the electrodes being spaced apart so as to define a water flow path between them, the electrodes comprising titanium outer electrodes and at least one inner diamond electrode | 08-21-2014 |
