This invention relates to a method, process and apparatus for disinfecting and sterilizing all types of surfaces contaminated with microorganisms and toxic substances to render both inactive. Furthermore, this invention relates to both a method and apparatus for disinfecting and/or sterilizing breathable air and then using this air to protect a confined space from external contamination. The apparatus consists of a new ultra-violet (NUV) source that is more effective than mercury based 254 nm light for destroying DNA of virus, bacteria, spores and cists. It is most effective in breaking chemical bonds in toxic gases and Biotoxins that are useful to terrorists. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.

This specification relates to an improved method, process and apparatus for disinfecting and sterilizing all types of surfaces and indoor air and room air contaminated with microorganisms. The improved apparatus consists of a multi-wavelength narrow spectral width UV source that is more effective than mercury based 254 nm germicidal lamps for destroying the DNA and outer shell or membrane of virus, bacteria, spores and cists.

Method and apparatus for producing a high level of disinfection in air and surfaces

A process for reducing particulate, Hg, NOx, and SO.sub.2 emissions from the combustion of fossil fuel while providing the capability of producing an end product that is commercially useful comprising the steps of oxidizing Hg, NOx and SO.sub.2 using a barrier discharge reactor to produce the HgO and acids HNO.sub.3 and H.sub.2 SO.sub.4, collecting the HgO, acids and particulates in a wet ESP, and then draining them from the wet ESP to remove them from the flue gas stream.

Barrier discharge conversion of Hg, SO.sub.2 and NOx

A power supply method particularly adapted for use with an electrostatic particulate collection device to provide substantially ripple-free DC power for improved operation. The power supply is adapted to receive three-phase AC power and to transform the AC power into high voltage DC power having a minimum of voltage ripple in the output. The power supply includes a multi-phase transformer having three primary windings, each of the primary windings having associated with it a pair of secondary windings. The primary windings can be either delta connected or wye connected. One of each of the secondary windings associated with one of the respective primary windings are connected together in a delta connection arrangement, and the remaining secondary windings are connected in a wye connection arrangement. Because the respective AC voltage outputs of each of the secondary windings is out of phase with the AC voltage outputs of the other secondary windings, the resultant combined DC output voltage, after the DC voltages have been rectified in a three-phase full-wave bridge rectifier stack, produces minimum ripple voltage and current, without requiring additional, more expensive, and less reliable components.

An electrical filter apparatus for an electrostatic precipitator, wherein the filter apparatus is a T-type or pi-type filter electrically connected to a high voltage output of an electrostatic precipitator power supply and an electrostatic precipitator electrode. The T-type filter comprises a first inductor electrically connected to the high voltage output and a capacitor that is also electrically connected to ground. A second inductor is connected to the first inductor and the electrostatic precipitator electrode. In another embodiment, a two-stage inductor assembly is provided having a third inductor member defined by a plurality of turns of a continuous length of wire, and a fourth inductor member defined by a plurality of ferrite beads in end-to-end relationship.

A process and apparatus for reducing particulate, nitrogen oxides ('NOx'), sulfur dioxide ('SO.sub.2 '), and mercury ('Hg') emissions from the combustion exhaust of fossil fuel fired plants while producing an end product that is commercially useful, comprising the steps of oxidizing Hg, NOx and SO.sub.2 using a barrier, pulse, corona, or electron beam electrical discharge apparatus to produce HgO and the acids HNO.sub.3 and H.sub.2 SO.sub.4, collecting the HgO, acids and particulates in a wet ESP, and separating the particulates from the collected acid mixture, then separating and concentrated the acids for industrial use.

A coaxial flashlamp for optical pumping of a tunable dye laser. The flashlamp includes electrodes preferably made from a tungsten-based alloy for reduced metallic vapor deposition within the flashlamp. Positioned around the outer tube is a packed powder material having a diffuse reflectivity of the order of at least about 98%. The outer surface of the outer tube is placed under an inwardly-directed pressure provided by a pressurized cooling liquid that serves both to cool the flashlamp and simultaneously to offset internally generated pressure within the flashlamp caused by the pressure wave resulting from the movement of the ionization front through the gas within the annular gas chamber defined between the inner and outer tubes.

A two-stage, high-voltage inductor assembly. The inductor assembly is particularly adapted for use in a power supply circuit for an electrostatic precipitator. The inductor assembly includes a first stage inductor member defined by a toroidal inductor member formed from a plurality of turns of wire to define an inductor member having a first inductance, and a second stage inductor member defined by a plurality of end-to-end ferrite elements carried on a copper conductor to define an inductor member having a second inductance. The first inductor member blocks the low to moderate frequency currents and voltages in the power output portion of an electrostatic precipitator power supply circuit, and the second inductor member blocks the intermediate and high frequency currents and voltages in such a circuit. The first and second inductor members can be carried on a single body member which can be of tubular construction and in which the first inductor member is exteriorly carried on the body member while the second inductor member, which is electrically connected with the first inductor member, is interiorly carried within the tubular body member.
