Alternatively, light radiation is applied during chemical action with oxygen so as to improve a composition efficiency of an organic compound and obtain a preferable decomposition amount. This reduces the load caused by an organic compound decomposition on the environment.Type: ApplicationFiled: January 11, 2001Publication date: July 12, 2001Applicant: Sony CorporationInventor: Yasuhito Inagaki

Patent number: 6030598Abstract: An ozone containing gas stream is produced from oxygen by subjecting oxygen to an electric discharge and the ozone is then adsorbed on to a solid adsorbent, such as zeolite, the oxygen containing stream leaving the adsorbent is recycled to the ozonising process. Periodically, oxygen adsorbed on the adsorbent is desorbed by co-currently passing a purge gas over the adsorbent and the desorbed oxygen is also recycled to the ozoniser. Lastly ozone is desorbed from the adsorbent by a counter-current flow of purge gas and used in an ozone demanding process.Type: GrantFiled: June 8, 1998Date of Patent: February 29, 2000Assignee: Air Products and Chemicals, Inc.Inventors: Anthony K. J. Topham, Rodney J. Allam

Patent number: 5891344Abstract: A flow control apparatus for enriching gas containing oxygen with ozone includes a generator for producing the enriched mixture. A flow meter is connected to the generator outlet to measure the flow of the generated enriched gas. A mass flow control device is connected downstream of the flow meter. A flow control comparator compares a flow value as obtained from the measuring means and a preset constant value. A signal output of the flow control comparator is connected to a signal input of the mass flow control device for varying the mass flow in accordance with the comparison. An outlet of the mass flow control device is connected to an inlet of a compressor for compressing gas, the inlet gas pressure varying to keep compressed gas at a constant pressure. Feedback is provided between an outlet and an inlet of the compressor. A second mass control device is intermediately connected along the feedback connection for adjusting the mass flow of gas passing through the feedback means.Type: GrantFiled: April 12, 1996Date of Patent: April 6, 1999Assignee: Ozonia InternationalInventors: Pierre A. Liechti, Helmut Lang

Patent number: 5705468Abstract: A vehicle and method for storing ozone is disclosed. A vehicle made of a water miscible, organic compound of a glycol-containing chemical compound, a tertiary alcohol or a mixture thereof that is capable of receiving and containing ozone is disclosed. The method involves producing ozone gas, introducing the ozone-containing gas into a mixing vessel that contains the aforementioned organic compound, agitating the organic compound in the presence of the ozone-containing gas, wherein the ozone-containing gas is at atmospheric pressure or at a pressure of up to about 150 psig., and releasing the pressure if pressures in excess of atmospheric are used.Type: GrantFiled: November 18, 1996Date of Patent: January 6, 1998Assignee: Quantum Technologies, Inc.Inventors: Robert E. Yant, Marilyn M. Hurst, David B. Galluch

Patent number: 5478533Abstract: A water treatment apparatus is provided in which the ozone generation and the water treatment may take place simultaneously. The ozone is generated from a continuous supply of air and/or oxygen at the surface of a running water by means of a high voltage electrode placed in the air or in oxygen at some distance above the water surface. The strong electric field between the high voltage electrode and the surface of the electrically grounded water stream generates a multitude of small Taylor cones at the surface of the water. Each Taylor cone goes into corona and in the process it generates the ozone. As the ozone is generated at the water surface, a substantial amount of ozone is immediately dissolved in water and the ozone that diffuses in the air continues to be in contact with the water surface. The undissolved ozone may be percolated through the same water for an additional primary or secondary ozonation.Type: GrantFiled: August 17, 1994Date of Patent: December 26, 1995Assignee: Cleft Engineering CorporationInventor: Ion I.

Patent number: 5407637Abstract: An apparatus and method for producing an antibiotic liquid. The apparatus includes an ion generator that produces negatively-charged molecules of the formula [MO.sub.x ].sup.-, where M is a positive ion, O is oxygen and x is a number at least equal to 3, and means for mixing a gas containing said molecules with a liquid such as water. Molecules [MO.sub.x ].sup.- are produced in a generator that comprises a specially shaped anode and cathode spaced apart from each other in a non-conducting housing. When a substantially constant voltage is applied across the anode and cathode, a plasma forms between and around them that in turn forms a magnetic field around the plasma and the anode. Diatomic oxygen molecules enter the housing and are polarized by the magnetic field and the resulting oxygen ions accelerated toward the plasma.Type: GrantFiled: March 30, 1994Date of Patent: April 18, 1995Assignee: Scientific Products CorporationInventor: James W.
