In particular, these systems comprise a water source, an ozone source, and a nozzle that mixes ozone and water to form a highly concentrated, ozonated water solution. Instead of requiring the ozonated water to be re-circulated to achieve a desired ozone concentration, the nozzle is configured to form the ozonated water solution in a single pass through the nozzle. Additionally, instead of requiring the ozonated water to be discharged into a pressurized tank to increase ozone absorption, the nozzle allows the ozonated water to be openly discharge. In some cases, the nozzle comprises a venturi with multiple ozone inlets to increase mixing. Additionally, in some cases the nozzle comprises a single pass mixing mechanism that mixes the water and ozone to form the high concentrate, ozonated water solution in a single pass through the nozzle.Type: ApplicationFiled: September 15, 2008Publication date: March 19, 2009Inventor: Thomas D.

Patent number: 7501011Abstract: A device for controlling relative humidity in an environment with a solidified humectant composition. The solidified humectant composition is made from a humectant salt, water, and a carrier. The solidified humectant may be formed into a tablet with the aid of a binder, or it may be contained within a thermoformed felt material, a sachet, or a water permeable canister. In a preferred embodiment, the sachet is made of a micro-perforated polyester/paper/polyethylene material. Preferred humectant salts include CaCl2, K2CO3, LiCl2, NaCl, K2SO4, and combinations thereof. A preferred embodiment of the present invention includes the use of one or more of: an antimicrobial agent, activated carbon, a volatile organic, a moisture adsorber and an oxygen absorber, in combination with the solidified humectant salt.Type: GrantFiled: November 9, 2004Date of Patent: March 10, 2009Assignee: Multisorb Technologies, Inc.Inventors: Thomas Powers, Louis Patrone

Publication number: 20080257151Abstract: A desiccating device includes a rigid container having an end sealed by a selectively permeable membrane, operative to admit water vapor into the container, but not allow water to pass out of the container. A desiccant separates water from water vapor that has entered the container. A removable impermeable membrane seals the container, and prevents water vapor from entering the container when the impermeable membrane is in place. A reinforcing member having apertures is placed above the selectively permeable membrane, enabling a thinner and weaker selectively permeable membrane. The container shape defines angles of less than 90 degrees, as in a triangle or other truncated rectangle, where the device may be placed in a corner, projecting into the area to be dried less than a rectangular or circular container.Type: ApplicationFiled: April 17, 2008Publication date: October 23, 2008Inventor: Jonathan A.

Patent number: 7431900Abstract: 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 (40?) is connected directly to the nipples (72, 92). When the desiccant cartridge (40?) is saturated, it is removed and placed in a regenerator unit (120). A regenerated cartridge is installed in its place.Type: GrantFiled: February 28, 2003Date of Patent: October 7, 2008Assignee: Steris IncInventors: Aaron L. Hill, Arthur T. Nagare, Frank E. Dougherty, Stanley M. Voyten
