  • Patent number: 6697706
    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.

  • Patent number: 6675840
    Abstract: A fill probe with an in-line mixer accelerates and facilitates automation of a fill and mix procedure required in formulating certain chemical products. In some formulas, the concentrated chemical components that combine to form the resulting formula (e.g., teat dip) have a wide range of viscosities. The in-line positioning of the mixing attachment with the fill probe on the outside of the fill probe creates a dual action mixing operation that mixes the components as they are deliver to a mixing container and continues to mix them after they are combined with other chemicals within the mixing container. By using a combination fill probe and in-line mixer of the claimed design, a user can automate the fill and mix process, decrease the required mix time, and reduce foaming and spillage of chemicals.

  • Patent number: 6673753
    Abstract: Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base.

  • Patent number: 6673765
    Abstract: A process for preparing a homogeneous, solid cleaning composition that comprises a cleaning agent, and optionally an additive agent and a hardening agent is provided. The compositions are processed in a continuous mixing system at high shear, at or below the melting temperature of the ingredients. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the cleaning composition. The consistency of the composition ranges from that of a fused block solid to a malleable article. The cleaning compositions are useful for warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, laundry detergents, conveyor lubricants, and the like.
