Patent number: 6780382Abstract: The present invention relates to dispensers for active materials, which dispensers employ heat conductive elements to distribute heat from a burning flame at a wick to a simmer plate and to the body of a solid fuel containing the active material, so as to more rapidly liquify the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to volatilize the active material. The heat conductive elements and simmer plate are configured so as to engage said solid fuel, and to cause the flow of liquified fuel to the wick. The fuel may comprise various active ingredients, such as fragrances, air fresheners, deodorizers, odor eliminators, odor counteractants, insecticides, insect repellants, herbal and medicinal substances, disinfectants, sanitizers, mood enhancers, aroma therapy compositions, and the like, and may be provided in various forms.Type: GrantFiled: December 20, 2000Date of Patent: August 24, 2004Assignee: S.C.

Patent number: 6699445Abstract: The present invention provides a system for, and method of, performing various liquid-liquid contacting operations such as solvent extraction, stripping, scrubbing, washing, re-extraction and reacting in a single, integrated column. The ability of the integrated column, which is based on the intermediate decanter, of the present invention, to perform the entire operation of solvent extraction plant in a single column has many technical, economical, ecological and operational safety advantages. Investment costs significantly decrease due to the decrease in the number of columns, decanters, and auxiliary equipment, spare parts, materials inventories and the requisite area for the plant relative to a standard prior art plant. Operating and maintenance costs also decrease due to less pumping between columns and less equipment in operation.Type: GrantFiled: August 16, 2001Date of Patent: March 2, 2004Assignee: Bateman Advanced Technologies Ltd.Inventor: Rafael Kleinberger

Patent number: 6696019Abstract: The invention is based on the discovery that biological and non-biological materials can be sterilized, decontaminated, or disinfected by repeatedly cycling between relatively high and low pressures. Pressure cycling can be carried out at low, ambient, or elevated temperatures (e.g., from about −40° C. to about 95° C., or intermediate ranges). New methods based on this discovery can have applications in, for example, the preparation of vaccines, the sterilization of blood plasma or serum, plant, animal, and human tissue, sputum, urine, feces, water, and ascites, the decontamination of military devices, food and beverage production, and the disinfection of medical equipment. The new methods can also be incorporated into production processes or research procedures.Type: GrantFiled: August 7, 2001Date of Patent: February 24, 2004Assignee: BBI BioSeq, Inc.Inventors: James A.

Fluid flow diverters and diversion methods and water purification equipment including such diverters
Patent number: 6680026Abstract: “Plug-in” fluid flow diverters are disclosed. Additionally disclosed is water purification equipment adapted to communicate with the diverters. Such equipment is especially (although not solely) useful in connection with circulating streams of water present in systems associated with swimming pools, hot tubs, and spas, as the circulating nature of the water permits more of its volume ultimately to be diverted into the equipment for purification. The diverters, furthermore, may have entrances oriented to receive fluid travelling in only one direction through a conduit and be keyed to one or more components of the equipment for purposes of identification, inventory control, or otherwise.Type: GrantFiled: May 5, 1999Date of Patent: January 20, 2004Assignee: Zodiac Pool Care, Inc.Inventors: Raymond P.

Patent number: 6656424Abstract: An ultraviolet area sterilizer (UVAS) is mobile or stationary. The UVAS is positioned in a room, such an operating room or intensive care unit. Motion detectors sense movement, to assure that personnel have evacuated the space to be sterilized. Subsequently, UV-C generators, such as a bank of mercury bulbs, generate intense levels of UV-C. An array of multiple UV-C sensors scan the room, and determine the darkest area, or the area reflecting the lowest level of UV-C back to the sensors. A BASIC Stamp contained in the device calculates the time required to obtain a bactericidal dose of UV-C reflected back from darkest area. Once a bactericidal dose has been reflected to all the sensors, the unit notifies the operator and shuts down. By relying on reflected doses rather than direct exposure, the UVAS is able to sterilize or sanitize all surfaces within the room that are within view of an exposed wall or ceiling.Type: GrantFiled: September 19, 2000Date of Patent: December 2, 2003Assignee: UVAS, LLCInventor: Jeffery L Deal
