Abstract: Rotational speed of a spray arm is regulated based on centrifugal force and a liquid jet to create a variable angle corner spray nozzle. The regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation pushes the weight outward, which increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and tends to push the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed independent from center pivot friction and the spray arm nozzle's orientation tolerance. Speed stabilizes when centrifugal force on the weight is equal to the pushing force of the fluid jet.

Abstract: A method for decontaminating articles having porous outer surfaces. The method includes providing a decontamination chamber; conveying the articles through the decontamination chamber at a predetermined speed wherein the speed is selected such that the articles are disposed in the decontamination chamber for a predetermined period of time; providing a source of sterliant vapor, the source providing the sterilant vapor at a temperature within a predetermined acceptable temperature range and at a concentration within a predetermined acceptable concentration range; conveying a sterilant vapor from the source of sterilant vapor to the decontamination chamber; and exposing the articles to the sterilant vapor. The predetermined period of time and the predetermined acceptable concentration range of the sterilant vapor are selected such that the sterilant vapor does not penetrate the porous outer surfaces of the articles.

Abstract: A method for decontaminating an object disposed in a region. The method includes the steps of: heating the region to a target temperature; introducing steam into the region until a humidity level in the region reaches a target humidity level; introducing a vaporized sterilant into the region until a sterilant concentration in the region reaches a target sterilant concentration; and maintaining the target temperature, the target sterilant concentration and the target humidity level until a predetermine target dose is obtained.

Abstract: A vaporizer for generating a vaporized chemical decontaminating agent. The vaporizer includes a primary flow path and a blower for conveying a carrier gas along the primary flow path. A secondary flow path has a first end fluidly connected to the primary flow path at a location upstream of the blower and a second end fluidly connected to the primary flow path at a location downstream of the blower. A heating element is disposed along the secondary flow path. A liquid flow path has a first end fluidly connected to a source of liquid chemical decontaminating agent and a second end fluidly connected to the secondary flow path. The liquid flow path injects the liquid chemical decontaminating agent into the secondary flow path at a location upstream of the heating element. The heating element vaporizes the liquid chemical decontaminating agent to form the vaporized chemical decontaminating agent.

Abstract: A fixture for holding a valve assembly in an automated washing system, wherein the valve assembly is movable between an opened position and a normally closed position. The fixture is comprised of first and second housing sections that are releaseably attachable to each other. The housing sections define an internal cavity that is dimensioned to hold the valve assembly in an opened position. A fluid inlet is in communication with the chamber, and is attachable to a source of an anti-microbial fluid in the washing system. A fluid outlet communicates with the chamber to allow the anti-microbial fluid to exit the fixture.

Abstract: A method and apparatus for treatment of a fluid medium to inactivate biocontamination using a pulsed electric field (PEF). A fluid medium is pumped through a treatment assembly to treat the fluid medium. A pulse generating system produces input pulses of high voltage that are supplied to the treatment assembly. A pulsed high intensity electric field associated with the input pulses is produced in a treatment assembly. As the fluid medium flows through the treatment assembly, it is exposed to the high intensity electric field, thereby treating the fluid medium. The pulse generating system includes a pulse compressor to reduce the rise time of the high voltage pulses supplied to the treatment assembly, and forming a pulsed electric field in space, without use of an electrode system.

Abstract: A powder of Anthrax spores or other microbial contamination in a series of conveyed envelopes or banknotes (2) are deactivated by pulses of energy. Preferably, the deactivation occurs in the normal processing and sorting of mail or paper currency. The pulsed energy is in the form of low kinetic energy (under 500 keV) enull beams (12) or x-rays which are pulsed in coordination with the movement of mail in the mail handling equipment or the movement of banknotes into or out of an automatic teller machine. The treatment of either mail or currency is done under nearly adiabatic conditions.

Abstract: A hydrogen peroxide vapor generation unit (10) receives hydrogen peroxide and water solution at an interface (20) and interconnects with an air dryer (14) by way of nipples (72, 92). In one embodiment, the dryer includes a clamping assembly (42) which is latched (74, 94) with the nipples and which receives a disposable desiccant cartridge (40). In an alternate embodiment, a reusable desiccant cartridge (40null) is connected directly to the nipples (72, 92). When the desiccant cartridge (40null) is saturated, it is removed and placed in a regenerator unit (120). A regenerated cartridge is installed in its place.
