Abstract:
An amperometric bromine control system accurately maintains a desired concentration of bromine within a home spa or in other water features. The control system employs amperometric sensing to measure the bromine concentration in the spa water and uses this measurement to control the electrochemical production of bromine through the oxidation of aqueous bromide. The level of bromide in the spa water desirably is greater than 50 ppm in order to obtain a linear relationship between the current level sensed through the amperometic measurement and the concentration level of bromine in the water. In this manner, the control system can accurately measure the bromine concentration in the spa water and precisely maintain the bromine concentration within a desired range between about 2 ppm and 6 ppm.

Medical devices are provided which utilize a highly flexible cable of two and preferably three or more strands of wire. The strands are twined to form a wire rope which is drawn through successive dies to reduce its diameter until the outer surface of the cable is substantially smooth. A cable so-formed has improved elasticity. The cable is used in medical devices in which increased elasticity of a wire-like element is desired. Twisted and drawn cables incorporating a strand of a radiopaque metal or alloy may be used in devices in which radiopacity of a flexible portion of the device is desired. Twisted and drawn cables incorporating a strand of a metal or alloy having high electrical conductance may be used in devices in which electrical conductivity of a flexible portion of the device is desired.

Abstract:
A water purification process comprises applying electrical energy to water to be treated in a treatment chamber having a cathode and an anode opposing each other and deactivates or destroys microorganisms in the water. Water in the vicinity of the anode is caused to flow away from the anode by subjecting the water and/or the anode to vibration. The water purification apparatus includes a treatment chamber (2) having a cathode (9) and an anode (3) opposing each other. Electrical energy is applied to microorganisms contained in the water. The anode and/or the water in the vicinity of the anode is vibrated and debris inside and outside the chamber is removed (17).

Chlorine ion-containing water supplied from one of water discharge pipelines of an electrolysis vessel of an apparatus for continuously forming electrolyzed water is caused to flow backwardly to one of electrode chambers and a water supply branch pipe thereof, passed through a water supply branch pipe of the other of the electrode chambers and/or a water supply pipeline at the upstream thereof and discharged through the other of the electrode chambers and from the other of the water discharge pipe lines. In this state, water in the electrolysis vessel is electrolyzed while operating the electrode of the electrode chamber in which water is caused to flow backwardly as an anode, and the electrolysis vessel and water channels at the upstream thereof are cleaned and sterilized by electrolyzed cleaning water in which hypochlorous acid is formed.Alternatively, water may be electrolyzed while supplying from a pair of water discharge pipelines backwardly into the electrolysis vessel, and electrolyzed cleaning water formed in the electrolysis vessel may be caused to flow backwardly and discharged from the water supply pipeline.
Abstract:
An apparatus for increasing the quantity of dissolved oxygen in water. The apparatus includes an inlet for receiving untreated water. A cell housing having an electrolytic cell therein is coupled to the inlet. A translucent resident time housing is connected to the cell housing for receiving water containing oxygen and hydrogen gas. The resident time housing is vertically oriented and longitudinally extended for a selected vertical length above the cell housing. This provides sufficient resident time of the water in a quiet zone to permit the generated oxygen gas to transition into the dissolved state prior to reaching the top of the resident time housing. An outlet is provided at the top of the resident time housing to dispense water having a high dissolved oxygen content. A gas vent is provided at the outlet to permit the escape of hydrogen or other gases which have not been dissolved into the water. Preferably, a chill unit is provided prior to the electrolytic cell to reduce the temperature of the water. Chilling makes the water pleasing for human consumption, as well as increases the water's ability to absorb dissolved oxygen. Additionally, a light or other artistic display may be provided adjacent to or with the resident time housing for the pleasure of viewers.

The invention provides a method and apparatus for producing an electrolytic water whereby one electrolytic water used in compliance with its intended use is transformed into a water more effectively used and the by-product electrolytic water, previously disposed as virtually useless, is transformed into a water which can be effectively used by use of at least two electrolyzer in series. At least one of an outlet for a primary anodic electrolytic water in a primary electrolyzer and an outlet for a primary cathodic electrolytic water in a primary electrolyzer is connected to an inlet of a secondary electrolyzer through a first switching valve and a second switching valve. The anodic electrolytic water only, the primary cathodic electrolytic water only, or mixture of the primary anodic and primary cathodic electrolytic water is fed to the secondary electrolyzer to be electrolyzed again. A chlorine remover is provided within the secondary inlet for connecting the primary electrolyzer with the secondary electrolyzer and it removes chlorine from a primary electrolytic water, and afterward, the filtered water is electrolyzed again in the secondary electrolyzer. Tertiary electrolysis of the secondary anodic electrolytic water, produced by electrolysis of the primary anodic electrolytic water, will produce a tertiary anodic electrolytic water that exhibits a remarkably high bactericidal effect.
