Abstract:
An apparatus for killing microorganisms in a primary flow of a fluid medium using germicidal beams to kill microorganisms in a portion of the primary flow of the fluid medium has a housing having an inlet end 1 and an outlet end 4. The housing 20 has reflective inner surfaces 2R, 3R, 5R and 6R along the path 100 of the germicidal beams, a source 30 of germicidal beams located in the housing 20 and at least one baffle 40 located near the source 30 of the germicidal beams. The baffle 40 projects from an inner surface 6 of the housing 20 and is configured to converge the primary flow of air into the germicidal beams path in close proximity to the germicidal beams source 30. The at least one baffle 40 has an upstream portion 41 lying substantially out of the beam path 100 and a downstream portion 42 lying in the beam path 100.
Abstract:
An ozonizer is disclosed, having a first electrode and a second electrode between which a discharge gap is formed, a dielectric being arranged between the first electrode and the second electrode. The dielectric comprises a support element made of glass or glass ceramic, onto which a thin dielectric film on the order of up to 100 &mgr;m is applied. The use of glass or glass ceramic as the dielectric, in conjunction with an additional thin ceramic dielectric film, allows a considerable improvement in the ozone concentration in the carrier gas, simultaneously with a good ozone yield.
Abstract:
A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.

A pair of electrodes (1a, 1b) are formed on one surface of a dielectric substrate (2). A dielectric layer (18) is formed on the surface of the dielectric substrate (2) so as to cover the pair of electrodes (1a, 1b). The pair of electrodes (1a, 1b) have linear electrode elements, respectively. The respective linear electrode elements are arrange at equal intervals.
Abstract:
There is disclosed a method of selectively increasing the hydrophilicity of a web, such as a plastic glucose electrochemical test strip. The web is corona arc treated, and a film of water is selectively applied to the web where a reduction of the effect of the initial corona treatment is desired. The water is then removed by drying.
Abstract:
A method and system for separating radioactive waste containing volatiles, into light ions and heavy ions, includes a loader/transporter for transferring the waste into a high vacuum environment in the chamber of a plasma processor. During this transfer, gases of the volatiles are released from the waste, collected in a holding tank, and subsequently ionized in the chamber. As the volatiles are ionized, the ions are directed by a magnetic field into contact with the waste to vaporize the waste. The waste vapors are then ionized in the plasma processor chamber to create a multi-species plasma which includes electrons, light ions and heavy ions. Within the chamber, the density of the multi-species plasma is established to be above its collision density in order to establish a substantially uniform velocity for all ions in the plasma. A nozzle accelerates the multi-species plasma to generate a fluid stream which is directed from the chamber toward an inertial separator. A magnetic field in the inertial separator effectively blocks electrons in the stream from entering the separator. On the other hand, the inertia of the various ions in the stream carry them into the separator where they are segregated into light ions and heavy ions according to their atomic weights. After segregation, the heavy ions are vitrified for subsequent disposal.
Abstract:
A system of deactivating microorganisms in water involves illuminating the microorganisms using at least one short-duration, high-intensity pulse of broad-spectrum polychromatic light. The system includes a watertight housing having an inlet port and an outlet port for the flow water. A tubular light source for deactivating microorganisms and a tubular baffle for directing the water flow are positioned within the watertight housing. Waters enters the inlet port and flows between the watertight housing and the tubular baffle in one direction, around the end of the tubular baffle and back through the center of the tubular baffle in a second direction exiting the outlet port. In one embodiment, the inlet and outlet ports are positioned at the same end of the watertight housing. In a another embodiment, the inlet port is at the end of the watertight housing and the outlet port extends radially from the tubular baffle through the side of the watertight housing. Additionally, a removable recirculating hose may be connected from the inlet port to the outlet port for recirculating the water. A quartz jacket filled with a cooling material may be used around the tubular light source to provide cooling to the light source and spectral filtering of the light emitted from the light source. The inner surface of the baffle may be reflectorized to reflect light from the light source.
Abstract:
In an exhaust gas processing apparatus for an internal combustion engine, supply power is fed to a corona discharge tube via a short-pulse high-repetition switching element to produce a corona. A harmful substance in exhaust gas of the internal combustion engine is removed by the corona. An MAGT (MOS Assisted Gate-Triggered Thyristor) is used as the short-pulse high-repetition switching element. Thus, the life of the switching element is increased and a high purification performance is achieved even at the time of start of operation when the temperature of exhaust gas is low.
Abstract:
An apparatus and method for producing colloidal silver. A large-volume container, such as a fifteen gallon container, includes a hinged lid on which a rotational impeller is mounted along with several sets of electrodes that are electrically connected to a power transformer. The container is partially filled with water, and when the lid is closed, the sets of electrodes are disposed in communication with the water in a predetermined arrangement, and the impeller resides submerged in the water. Certain of the electrodes constitute silver wire. The power transformers convey current to the electrodes, preferably alternating current, at voltages sufficient to cause silver particles to separate from the silver wire and enter the solution in a stable, suspended state. The impeller is rotated, preferably continuously, to prevent the suspended silver from remaining in upper levels of the water, thereby dispersing the silver particles more uniformly throughout the volume of water.
Abstract:
A substrate is configured with first and second sets of electrodes, where the second set of electrodes is positioned asymmetrically between the first set of electrodes. When a RF voltage is applied to the electrodes sufficient to generate a discharge plasma (e.g., a one-atmosphere uniform glow discharge plasma) in the gas adjacent to the substrate, the asymmetry in the electrode configuration results in force being applied to the active species in the plasma and in turn to the neutral background gas. Depending on the relative orientation of the electrodes to the gas, the present invention can be used to accelerate or decelerate the gas. The present invention has many potential applications, including increasing or decreasing aerodynamic drag or turbulence, and controlling the flow of active and/or neutral species for such uses as flow separation, altering heat flow, plasma cleaning, sterilization, deposition, etching, or alteration in wettability, printability, and/or adhesion.
