  • Patent number: 6973894
    Abstract: A timing device for visually determining the passage of a preselected period of time including a tube (2) having opposed ends with at least one of the opposed ends having a reservoir (10a, 10b) for storing a reactant or an indicator, a transport system (12) extending from the reservoir to the other of the opposed ends of the tube (2) for transporting at least one of the reactant or the indicator until they contact each other, a reactant, and an indicator which when in contact with the reactant via the transport means (12) emits an observable change in property wherein the minimum length of the period of time corresponds to the time it takes for the reactant and indicator to contact each other. Thc tube (2) has a shape which undergoes at least two material changes of direction exceeding 90° and up to 180° from one of the opposed ends to the other.

  • Patent number: 6818235
    Abstract: The present invention provides a method for beneficial control of body condition and dietary energy balance in dairy cattle during colostrum milk production. An important aspect of the beneficial control is the provision of a feedstock which has a supplemented content of trans-10, cis-12 conjugated linoleic acid derivative having rumen-bypass properties. The ingested quantity of CLA derivative ingredient per cow is effective for lowering and maintaining the fat content of colostrum milk in the range between about 4-6 weight percent and for increasing milk yield. The presence of cis-9, trans-11 conjugated linoleic acid structural isomer in an invention feedstock is minimized, because it counteracts the beneficial effects of the trans-10, cis-12 conjugated linoleic acid structural isomer, such as reduction in milk yield.

  • Patent number: 6746997
    Abstract: A process for the preparation of mixed ethoxylated alkyl phenol/alkyl phenol ethoxy sulfate surfactants, such surfactants, and detergent formulations incorporating the same. The mixed surfactants are more tolerant of sodium carbonate, allowing greater amounts of sodium carbonate to be used so that the amount of surfactant can be reduced resulting in overall cost savings in the resultant laundry product.

  • Patent number: 6596768
    Abstract: This invention provides a feedstock for ruminants which beneficially improves feed efficiency and body growth. The feedstock also is adapted to improve the lactational performance of dairy cattle. The recovered milk product has a milk fat profile with an increased proportion of unsaturated fatty acid constituents. The enhanced benefits exhibited by an invention feedstock are derived from essential ingredients such as unsaturated fatty acid derivative having rumen-bypass properties, and an effective additive quantity of cyclic polyether ionophorous antibiotic.

  • Patent number: 6485708
    Abstract: Improved one-part and two-part liquid products such as, e.g., mouthwashes, mouthrinses, toothpastes, gels and the like, for remineralizing subsurface lesions and/or mineralizing exposed dentin tubules in teeth contain a cationic component, an anionic component and a separating means for separating the cationic and anionic components. The anionic component contains water-soluble phosphate and fluoride salts, while the cationic component contains at least one partially water-soluble calcium salt and preferably at least one water-soluble salt of a divalent metal other than calcium. The tooth is treated with a mixed aqueous composition formed by mixing the cationic and anionic components with water and/or saliva. The mixed aqueous composition has a pH of from about 4.0 to about 10.0 and, in addition to dissolved calcium cations and dissolved phosphate and fluoride anions, contains a quantity of undissolved calcium salt.
