| 20080250928 | Differential ion generator - A dual ion generating module is incorporated into a conventional household appliance. The module alternately generates both positive (Antions) and negative (Anions) ions when the appliance is powered. | 10-16-2008 |
| 20090151567 | Space efficient hybrid air purifier - A compact, hybrid particulate and gas collector that can be used in an ultra-clean air purification, vehicle emissions control system, gas turbine, or in any other application where space and lower cost is important or in applications where sub-micron and nano-particulate filtering is needed such as in clean rooms and surgical suites. A gas flow enters the device in a first chamber and can be immediately exposed to a high-tension corona discharge electric field which typically results in a strong ionic flow by charging and collecting the incoming effluent (oil mist, soot particles, etc.). Subsequently, the charged flow enters a second zone of high-tension uniform electric field that causes the remaining charged particles to migrate to one of the charged electrodes. One of the electrodes can be made of porous filter material that allows the cleaned gas to flow into an exit zone also containing a high-tension uniform electric field where the remaining effluent can be collected prior to the ultra-clean gas exiting either to ambient air or being re-circulated to be used again by the engine. In some embodiments a dielectric barrier discharge surface can be provided to convert harmful compounds to more desirable substances. Alternate embodiments can include a third zone containing a second substantially uniform electric field as well as coating the porous surface with a catalyst to convert undesirable compounds. Any cross-section of the device may be used. Further treatment of the dust free flow with ultraviolet light, an x-ray or a radiation can be used to kill micro-organisms. | 06-18-2009 |
| 20100005970 | Industrial air purifier - An air purifier for industrial plants has an air pump and a water cleaner and an ultraviolet (UV) cleaner. The air duct has an air outlet, air inlet, first duct casing and second duct casing. The first duct casing and the second ducting casing each has a top being connected by a connecting tube and are bigger than the air outlet. The water cleaner is mounted in the first duct casing of the air duct. The UV cleaner cleans and purifies dirty air and has multiple UV generators. The air purifier sprays water to contain particulates in the dirty air and decomposes the pollutants using UV. Since the dirty air in the air duct has enough reactive time to turn into the clean air, the air purifier without any air-cleaning agents generates clean air without air cleaning agents in the air to endanger people and the environment. | 01-14-2010 |
| 20100011959 | ELECTROSTATIC PARTICLE FILTER - The invention relates to an electrostatic particle filter for removing particles from air. The electrostatic particle filter comprises a filter medium ( | 01-21-2010 |
| 20100162893 | Reflux Trap Device - A reflux trap for use in a plasma generator and delivery system to prevent back flow of fluids and debris from a patient to the plasma generator during a surgical procedure comprising a trap housing including a proximal diffuser chamber and a distal deflection chamber having a collection area separated by a baffle disposed within the trap housing having at least one gas flow aperture formed therethrough, a proximal inlet port and a distal outlet port formed on opposite end portions of the trap housing to feed gas to and from the trap housing through the proximal diffuser chamber, gas flow aperture and the distal deflection chamber, the baffle further includes a diffuser member disposed in the proximal diffuser chamber such that gas fed into the proximal diffuser chamber through the proximal inlet port impigns thereon and diffused through the gas flow aperture into the distal deflection chamber and through the distal outlet port to the surgical site on the patient and a deflection member disposed in the distal deflection chamber such that fluids and debris flowing back from the patient through the outlet port into the distal deflection chamber impign thereon and are deflected away from the gas flow aperture to the collection area preventing fluids and debris from migrating through the gas flow aperture into the proximal diffuser chamber isolating the plasma generator against any back flow of fluid and debris from the patient. | 07-01-2010 |
| 20110100221 | Air purifier - An air purifier includes a vertically disposed housing provided with a wire gauze filter, electric fans and air filter elements. The electric fans draw outside air around the floor vertically into the bottom air intake port toward the top air output port of the housing so that the flow of air, when passed out of the air output port, flows upwards to a certain elevation and is then diffused and lowered in all directions around the housing. By means of the traction of the flow of air, the pressure difference of the convection of air between the low air pressure and the high air pressure at the bottom and top sides of the housing, high concentration of car waste gas, micro dust particles, hair dust, micro fibers and other harmful industrial odors that fall to the floor due to the effect of gravity or floating nearly above the floor are sucked into the inside of the housing by the low air pressure zone at the open bottom side of the housing and then removed by the filter elements. | 05-05-2011 |
