20120301739 | METAL PRETREATMENT COMPOSITION CONTAINING ZIRCONIUM, COPPER, ZINC, AND NITRATE AND RELATED COATINGS ON METAL SUBSTRATES - A pretreatment composition for metal that provides enhanced corrosion resistance, enhanced paint adhesion and reduced chip damage to a wide variety of metal substrates. The pretreatment is also cleaner because it is based on zirconium rather than zinc phosphates. The pretreatment coating composition in use preferably comprises 50 to 300 parts per million (ppm) zirconium, 0 to 100 ppm of SiO | 11-29-2012 |

20080283152 | RINSE CONDITIONER BATH FOR TREATING A SUBSTRATE AND ASSOCIATED METHOD - A rinse conditioner bath that comprises a Jernstedt salt and a soluble iron is disclosed. A method for treating a substrate with the disclosed rinse conditioner bath as well as a zinc phosphate solution is also disclosed. | 11-20-2008 |
20130266819 | METAL PRETREATMENT COMPOSITION CONTAINING ZIRCONIUM, COPPER, AND METAL CHELATING AGENTS AND RELATED COATINGS ON METAL SUBSTRATES - Disclosed is a zirconium-based metal pretreatment coating composition that includes a metal chelator that chelates copper in the metal pretreatment coating composition and thereby improves adhesion of paints to a metal substrate coated with the pretreatment coating composition. The pretreatment coating composition has a longer pot life than one without the metal chelator and therefore can accommodate a wide latitude of application times. The chelating agent is present in a sufficient amount to ensure that in the deposited pretreatment coating on the metal substrate the average total atomic % of copper to atomic % of zirconium is equal to or less than 1.1. The pretreatment coating composition is useful for treating a variety of metal substrates. | 10-10-2013 |

20080241577 | CONVERSION COATINGS INCLUDING ALKALINE EARTH METAL FLUORIDE COMPLEXES - An aqueous composition for pretreating and depositing a coating on metal substrates is provided. The coating composition includes from about 1,500 to about 55,000 ppm based on the aqueous composition of a Group IIA dissolved metal ion, from about 100 to about 200,000 ppm based on the aqueous composition of a dissolved complex metal fluoride ion wherein the metal atom is selected from Group IIIA, Group IVA, Group IVB metals, Group VA, Group VB metals; and water. The composition is free of Group IIA metal fluoride precipitate achieved by including in the composition a complex metal salt different than the salt associated with the complex metal fluoride ion, with the complex metal salt being capable of complexing free fluoride ions to prevent a precipitation reaction. A process for coating a metal substrate with such an aqueous composition is further provided. | 10-02-2008 |

20080275318 | BIOSENSORS FOR MEASURING ANALYTES IN THE INTERSTITIAL FLUID - The invention relates to methods and devices for measuring blood glucose levels in a subject, where the methods and devices are designed for exposing a sensing mechanism to interstitial fluid in the subject. | 11-06-2008 |
20160075460 | SYSTEM FOR SORTING AND DISPENSING ORAL MEDICATIONS - A system for assisting patients in sorting and dispensing medication supplies comprises a storage tray having a number of storage compartments, and a communication system to identify a medication to be provided from a pill bottle and, based upon the identification and a known regime, automatically identify which compartments of the storage tray are to be filled with the identified medication from the pill bottle and perform the filling of the storage tray. In doing so, a patient can simply open and present any number of pill bottles to the system, and then allow the system to arrange the medication in the storage tray according to the known regimen. The regimen and regimen updates are communicated to the system by means of a wired or wireless transmission to the system from a remote location (e.g. pharmacy or doctor's office), by direct user input, or by reading such information from a barcode or similar information carrier affixed to the pill bottles. | 03-17-2016 |
