  • Patent number: 6773668
    Abstract: A solid detergent dispenser for use with a dishwashing machine includes a chamber and a lid. The chamber is configured and arranged to receive a solid detergent having a particular composition. A water inlet receives water from a water source, and the water flows through a tunnel into the bottom of the chamber. The chamber is flooded with water from the bottom to ensure relatively constant erosion of the solid detergent, which ensures that a relatively constant concentration of the solid detergent is used in the dishwashing machine. A water outlet allows water to flow out of the chamber into the dishwashing machine. The water must flow into the chamber faster than it flows out of the chamber to ensure that the appropriate amount of dissolution of the solid detergent occurs. The only valve used in the preferred embodiment is a valve to control the amount of water flowing into the water inlet.

  • Patent number: 6763860
    Abstract: A method and system for formulating and dispensing a chemical product to a dispense location is disclosed. The chemical product is formulated using one or more chemical concentrates. The chemical concentrates may be stored in concentrate containers and provided to a formulator by associated concentrate pumps. The concentrates are pulled from the containers through a manifold and to the formulator. The formulator discharges the chemical concentrates through a dispense hose having an outlet valve to the dispense location. The dispense location may be a jug or a drum. A flow meter connected between the formulator and the dispense hose. The flow meter monitors the component chemical concentrates flowing through the dispense hose and measures volumetric information associated with each component chemical concentrate. A flow controller analyzes the volumetric information generated by the flow meter and controls the volume of each component chemical concentrate dispensed to the dispense location.

  • Patent number: 6756349
    Abstract: Iodine and iodophor stains are masked by applying to the stain sufficient starch to impart a bluer coloration to and thereby mask the stain. The masked stain can be left as is until further cleaning or other surface repair or replacement can take place. The masked stain may instead or also be subjected to the action of a suitable decolorizing agent. Meanwhile, the masked stain typically will be much less objectionable in appearance than the original stain.

  • Patent number: 6743758
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

  • Publication number: 20040088076
    Abstract: 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 association 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.

  • Publication number: 20040088075
    Abstract: A method and system for collecting information associated with warewashing activities is disclosed. Articles to be cleaned by a warewasher are placed in racks designed to fit inside a wash chamber of the warewasher. Each rack is assigned a unique identifier (ID). No two racks are associated with the same unique ID. An Radio Frequency IDentification (RFID) tag is embedded within or placed on the outer shell of each rack. The RFID tag of a rack is programmed with the unique ID assigned to the rack. An RFID reader reads the unique ID of each rack as the racks are placed into the warewasher. The RFID reader transmits the unique ID to a host computer where the unique ID is stamped with a time reference, stored and eventually uploaded to a server computer. The unique ID and associated time reference are analyzed by the server computer, the host computer or a client computer connected to the server computer in order to monitor performance of the warewasher.
