In the pairs of electrode plate at least one electrode plate comprises holes connected to a feed pump for an auxiliary medium. Said pairs of electrode plates are positioned between the inlet and outlet in the container or tank such that in at least part of the flow route between the inlet and outlet the water passes upwards in the vertical passages. The feed pump for the water to be treated and/or the feed pump for the auxiliary medium is a pulsating feed pump.Type: ApplicationFiled: May 27, 2011Publication date: November 29, 2012Applicant: Atlantis Life Systems IncorporatedInventor: Erkki HÄIVÄLÄ

Patent number: 8317985Abstract: An electrolyte electrolyzer adapted to create hydrogen and oxygen from electrolyte fluid at or near atmospheric pressure. The electrolyzer is comprised in a preferred form of a plurality of cells which collectively create oxygen and hydrogen chambers separated by an ion permeable membrane. The electrolyzer is further defined by a passive electrode that is electrically interposed between a charged anode and cathode. The chambers defined by the cells are in communication with oxygen and hydrogen supply lines to transfer the hydrogen gas from the unit.Type: GrantFiled: November 19, 2007Date of Patent: November 27, 2012Assignee: Wood Stone CorporationInventor: Tadeusz Karabin

Patent number: 8308919Abstract: An electrolysis device to separate water into its more economically valuable constituent hydrogen and oxygen gases. A neutral plate is interleaved between every magnetically charged electrode in an electrode stack to provide a means of spark suppression, a physical barrier between the hydrogen gas created at the cathode and oxygen gas created at the cathode, and to reduce deterioration of electrode surfaces caused by alternating polarity from an anode state to a cathode state. Scale of electrolysis cell electrodes are partially cleaned through a cycling of system polarity through a neutral electrode period. A means is provided to isolate and segregate dissociated hydrogen and oxygen gas.Type: GrantFiled: November 18, 2009Date of Patent: November 13, 2012Inventor: Timothy Fletcher

Patent number: 8303798Abstract: The invention is a unit that produces Hydrogen Gas (Browns Gas (HHO)) that can be used as an assist to diesel and gas engines. The gas is produced from distilled water, using our stainless steel plate design. The patent should apply to the internal plate placement and design. The internal design of the unit allows it to produce significantly more hydrogen, drawing significantly less current or electricity from its power source. The internal design is in the placement of positive, negative and neutral plates to produce the gas.Type: GrantFiled: May 11, 2009Date of Patent: November 6, 2012Inventors: James D. Dees, Ken Colclesser, April R. Saldivar, legal representative

Patent number: 8282812Abstract: An apparatus for producing hydrogen from salt water by electrolysis. The apparatus includes a cathode plate and an anode plate spaced apart from the cathode plate. The apparatus also includes a cathode end connector for electrically connecting the cathode plate to a negative terminal of a direct current electrical power supply, and an anode end connector for electrically connecting the anode plate to a positive terminal of the direct current electrical power supply. The cathode plate is made from aluminum, and the anode plate is made from zinc. The aluminum cathode plate may have a multiplicity of apertures therein. It has been determined that the aluminum cathode plate and the zinc anode plate tend to provide an effective combination for salt water electrolysis.Type: GrantFiled: June 29, 2010Date of Patent: October 9, 2012Inventor: John Christopher Burtch

Patent number: RE47092Abstract: An oxygen emitter which is an electrolytic cell is disclosed. When the anode and cathode are separated by a critical distance, very small microbubbles and nanobubbles of oxygen are generated. The very small oxygen bubbles remain in suspension, forming a solution supersaturated in oxygen. A flow-through model for oxygenating flowing water is disclosed. The use of supersaturated water for enhancing the growth of plants is disclosed. Methods for applying supersaturated water to plants manually, by drip irrigation or in hydroponic culture are described. The treatment of waste water by raising the dissolved oxygen with the use of an oxygen emitter is disclosed.Type: GrantFiled: March 30, 2016Date of Patent: October 23, 2018Inventor: James Andrew Senkiw
