Publication number: 20030195657Abstract: A data processing system is used to manage and track use of chemical product in a washing machine. A detergent dispenser distributes the chemical products (e.g., detergent, rinse agent, and bleach) to the washing machine. The dispenser includes a monitor that detects dispenser data based on distribution of the chemical product by the dispenser. A database is coupled to the dispenser and stores an account identifier and an alignment identifier in association with the dispenser data of the dispenser. The database further stores corporate data in associating with the dispenser data, the account identifier, and the alignment identifier. An analysis application analyzes the dispenser data in relation with the corporate data to characterize use of the chemical product in the chemical application system and provide a feedback loop. The analysis application can limit its analysis to data associated with a given account identifier or a given alignment identifier.Type: ApplicationFiled: April 14, 2003Publication date: October 16, 2003Applicant: Ecolab Inc.Inventor: James P.

Publication number: 20030194433Abstract: Antimicrobial compositions containing a singlet oxygen-generating agent and a lubricant exhibit very effective antimicrobial activity against a variety of organisms, including Gram-positive bacteria, Gram-negative bacteria, fungi and yeast. The compositions have particular utility as beverage container lubricants. The passage of a container along a conveyor is antimicrobially lubricated by applying a lubricant to at least a portion of the container-contacting surface of the conveyor or to at least a portion of the conveyor-contacting surface of the container and generating singlet oxygen in situ. This method provides effective control of microbes on a beverage conveyor line, at rates comparable to purely chemical biocidal systems.Type: ApplicationFiled: March 12, 2002Publication date: October 16, 2003Applicant: EcolabInventors: Robert D.P.

Patent number: 6630042Abstract: The present invention includes a method of reducing slippage between a mat having a flexible polymer back surface and a substrate surface contiguous to the back surface, the method comprising applying a liquid comprising an aqueous solution of poly(vinyl acetate) to the back surface and contacting the back surface with the liquid thereon to the substrate surface while the aqueous solution is still wet. The method is especially effective where the mat comprises a flexible polymeric back surface comprising a flexible polymer selected from the group consisting of natural rubber, synthetic rubber, natural elastomers and synthetic elastomers. The contacting may be performed before the aqueous solution is completely dried. The aqueous solution may be applied directly to the back surface by spraying said aqueous solution onto said surface. The aqueous solution may be applied directly to the substrate surface.Type: GrantFiled: October 19, 1998Date of Patent: October 7, 2003Assignee: Ecolab Inc.Inventors: Kim R. Smith, David J.

Publication number: 20030184442Abstract: A method and apparatus for capacitively sensing one or more pests is disclosed. The detector may be employed as either a passive detector and/or as a part of a combined detector and trap. The sensor system includes at least two sensor electrodes and a capacitance sensing circuit. When a non-capacitive object, such as a pest, approaches the sensor electrodes, the capacitance of the sensor electrodes increases due to the object having a higher dielectric constant than air. A capacitance sensing circuit detects the increased capacitance and provides an output signal that a pest has entered the area being monitored. The capacitance sensing circuit may also be constructed to measure the change in the electrode in order to determine the size and/or type of pest based on a characteristic change.Type: ApplicationFiled: March 27, 2003Publication date: October 2, 2003Applicant: Ecolab Inc.Inventors: James P.

Patent number: RE38262Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid.Type: GrantFiled: March 2, 2001Date of Patent: October 7, 2003Assignee: Ecolab Inc.Inventors: John J. Rolando, Terry J.
