Abstract:
A method of sanitizing hard and soft goods comprising placing the goods within an a sealable enclosure; sealing the enclosure; producing ozone within the sealed enclosure; circulating the ozone within the sealed enclosure to sanitize the goods; adjusting the environment within the enclosure to optimize the sanitizing properties of and reduce the potential for the ozone to leak to the surrounding environment; removing the ozone to a prescribed safe concentration level; and maintaining the seal of the enclosure until the ozone concentration reaches the prescribed safe concentration level. The enclosure includes an open side; a sealing door for sealing the sealable enclosure; a locking mechanism; a circulation device, a fresh air heater; a vacuum pump, an ozone generator; an ozone destructor, wherein the ozone generator and ozone destructor are disposed within the sealable enclosure; and a humidification device to adjust the relative humidity inside the sealed enclosure.
Abstract:
A communications system and method involving a set top box (STB) and a channel stacking switch (CSS). The STB comprises a communications interface configured to issue a request for a user band, the request identifying the STB and further configured to receive a message identifying an assigned user band; and a tuning element configured to tune to the assigned user band in response to receipt of the message. The CSS comprises a communications interface configured to receive the request for a user band identifying the STB; a memory; and a processing entity configured to access the memory to identify a particular user band that is available for the STB and to assign the particular user band to the STB; wherein the communications interface is further configured to issue to the STB a message identifying the particular user band assigned to the STB.
Abstract:
The sterilization method disclosed includes the steps of - providing a sterilization chamber; - placing the article into the sterilization chamber; - sealing the sterilization chamber; - equalizing the temperature of the article and the sterilization atmosphere while the chamber is sealed; - applying a vacuum of a preselected vacuum pressure to the sterilization chamber; - supplying water vapour to the sterilization chamber under vacuum; - supplying ozone-containing gas to the sterilization chamber; - maintaining the sterilization chamber sealed for a preselected treatment period; and - releasing the vacuum in the sterilization chamber; whereby a vacuum pressure is used which lowers the boiling temperature of water in the sterilization chamber below the temperature in the sterilization chamber. The temperature equalization step is carried out while the chamber is sealed to prevent localized condensation of water during the subsequent step of supplying water vapour into the chamber.
Abstract:
An electro chemical conversion cell that can break down certain gasses to provide ozone and monovalent oxygen from a supplied volume of a suitable 02-containing gas. The conversion cell is provided with at least one metal mesh electrode within a generator reaction chamber, and a power supply which is adapted to supply a high alternating electric current voltage to at least partially break-down O 2 in the input gas to yield ozone. A fluid flow passage extends through the reaction chamber as a generally elongated passage through the reaction cavity. The fluid flow passage extends from an upstream end, where the O 2 -containing gas is initially supplied into the housing, to a downstream end where treated gas either flows outwardly therefrom under pressure or is evacuated from the housing. In a simplified construction, the fluid flow passage is delineated by a series of electrically insulating plates and/or spacers which are used to partition the reaction cavity.
Abstract:
An electro-kinetic electro-static air conditioner (100) includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays (230 and 240). Preferably the first array (230) comprises one or more wire electrodes (232) spaced staggeringly apart from a second array (240) comprising hollow "U"-shaped electrodes (242). Preferably a ratio between effective area of an electrode in the second array (240) compared to effective area of an electrode in the first array (230) exceeds about 15:1 and preferably about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. A bias electrode, electrically coupled to the second array electrodes (242), affects net polarity of ions generated. The outflow of ionized air and ozone is thus conditioned. Output airflow may be sampled for ozone and/or ion content, and/or the local environment may be sampled for parameters such as temperature and humidity. Such sampling could then be fedback to the invention and used to regulate desired output airflow characteristics.
Abstract:
This invention relates to an ozone generator for generating ozone by carrying out corona discharge between electrodes opposed each other in air. This ozone generator is intended to make compact the apparatus as a whole and to simplify its maintenance by reducing the number of its accessories. To this end, blades are formed by one of the electrodes while a casing is formed by the other electrode so that the blades and the casing constitute a blower. According to this structure, any separate blower for sequentially supplying fresh air to a corona discharge field and for sequentially extracting the generated ozone becomes unnecessary.
