Publication number: 20020125196Abstract: Raw water is treated with chlorine, chlorine dioxide and ammonia in various stages as it proceeds from raw water acquisition through clarification (e.g., coagulation, flocculation, sedimentation, and filtration) to storage of finished water from which the treated water can be introduced into a distribution system. Chlorine dioxide can be used as a pre-oxidant or disinfectant. Chlorine can be used as a disinfectant or to react with ammonia to produce monochloramine.Type: ApplicationFiled: March 8, 2001Publication date: September 12, 2002Applicant: CDG Technology, Inc.Inventors: Aaron A.

Patent number: 5326546Abstract: A method and apparatus for the generation, use, and disposal of chlorine dioxide is disclosed. A solid sodium chlorite composition having impurities, at least one of which is sodium hydroxide, is contacted with an agent to consume essentially all of the sodium hydroxide. Chlorine dioxide gas is then generated by contacting the resultant composition with chlorine in a humidified inert carrier gas. The resultant chlorine dioxide gas mixture may then be treated to remove chlorine gas present therein by contacting the same with soda-lime in particulate form. After using the chlorine dioxide gas mixture in the desired manner, chlorine dioxide present in the spent effluent gas may be substantially removed via the introduction of the effluent gas into an aqueous solution of sodium thiosulfate having a sufficient amount of an inorganic base to maintain the alkalinity of the solution during consumption of thiosulfate by chlorine dioxide.Type: GrantFiled: April 29, 1992Date of Patent: July 5, 1994Assignee: Iolab CorporationInventors: Aaron Rosenblatt, David H. Rosenblatt, David Feldman, Joseph E. Knapp, Diane Battisti, Badie Morsi

Patent number: 4908188Abstract: A system for treating articles, preferably with a sterilizing, gas is disclosed. The system includes a chamber into which the articles are received and valves for supplying the sterilizing gas to the chamber and for removing the gas from the chamber after a predetermined time period. The sterilizing gas is generated on site from at least two components, thus minimizing problems in the transportation of the gas to the location. The sterilizing gas generated on site is preferably chlorine dioxide and the two components may be chlorine gas and sodium chlorite. The system includes a programmed microprocessor controller for controlling the valves executing a predetermined sequence of instructions. The predetermined sequence of instructions define a state diagram for the system having a plurality of successive states. In order to provide for system safety, the controller preferably employs a plurality of abort states to which the system returns in the event of a failure.Type: GrantFiled: April 14, 1988Date of Patent: March 13, 1990Assignee: The Scopas Technology Company, Inc.Inventors: Raymond P. Jefferis, III, Phillip V. Engler, Aaron A. Rosenblatt

Patent number: 4681739Abstract: A method for sterilizing a substantially gas impermeable surface which is contaminated with spores comprises the steps of exposing the surface to a humid gaseous environment to enhance the susceptibility of the spores to subsequent chemosterilization, and then exposing the spores to an amount of gaseous chlorine dioxide in an inert carrier gas effective to sterilize the surface and a method for sterilizing an article contaminated with spores which comprises exposing the surface to a gaseous atmosphere comprised of chlorine dioxide gas and water vapor, wherein the amount of water vapor in said atmosphere is adapted to enhance the susceptibility of said spores to the sporicidal action of chlorine dioxide.Type: GrantFiled: April 18, 1984Date of Patent: July 21, 1987Assignee: The Scopas Technology Co., Inc.Inventors: David H.

Patent number: 4262529Abstract: The disclosure relates to a pressure sensitive indicating device of extremely simplified nature, providing a visual indication of a predetermined pressure threshold level. A typical and advantageous form of the device is a valve or valve extension member for a pneumatic tire, providing a visual indication of the existence or not of a desired pressure level. The device, in its most basic form, comprises an element formed of a natural or synthetic deformable elastomer, designed to expand upon exposure to increasing pressure levels. A covering element is associated with the deformable elastomer and is displaced by distention of the elastomer. By providing the deformable elastomer in a distinctively different color than the cover element, the displacement of the cover upon pressurization to a desired threshold, is readily evident to the observer.Type: GrantFiled: June 13, 1979Date of Patent: April 21, 1981Assignee: James C. AdkinsInventors: Aaron A. Rosenblatt, Walter J. Mann

Patent number: 4260261Abstract: The application discloses a food probe comprising an optical rod insertable in a body of food, for example, a roast of meat. At its inner end, the rod is configured to receive and transmit axially through the rod a color image of the food in the area contacted by the end of the rod. The image is transmitted to the outer end, where it is desirably magnified for convenient viewing of internal conditions. If desired, the probe may provide for a plurality of viewing areas, for simultaneously viewing the food at multiple depths. The probe preferably is rigid but may be connected to a flexible fiber optic bundle for viewing at a remote location.Type: GrantFiled: July 23, 1979Date of Patent: April 7, 1981Assignee: QEDInventors: Walter J.
