  • Patent number: 8628232
    Abstract: A method for introducing inhibitor into a fluid to be treated by forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s?1 in a high shear device comprising at least one generator comprising a rotor and a complementarily-shaped stator, wherein the rotor and the stator each comprise grooves, and wherein the grooves of the stator and the grooves of the rotor of each generator are disposed in alternating directions, and using at least a portion of the dispersion to inhibit corrosion.

  • Patent number: 8282266
    Abstract: A method for introducing inhibitor into a fluid to be treated by forming a dispersion comprising droplets, particles, or gas bubbles of the inhibitor dispersed in a continuous phase of a carrier, wherein the droplets, particles, or gas bubbles have a mean diameter of less than 5 ?m, and wherein either the carrier is the fluid to be treated or the method further comprises introducing the dispersion into the fluid to be treated. A system for inhibiting an undesirable component, the system comprising at least one high shear mixing device comprising at least one generator comprising a rotor and a stator separated by a shear gap, wherein the high shear mixing device is capable of producing a tip speed of the rotor of greater than 22.9 m/s, and a pump for delivering a mixture of a carrier and an inhibitor to the high shear mixing device.

  • Patent number: 8013022
    Abstract: Disclosed is a multi-compartment medical device useful in the storage, processing and extended shelf life of perishable products, especially pharmaceutical, food and biological products. Particular biological materials processed according to the present methods are human blood and blood products (RBCs). Also disclosed are processes for preserving food, pharmaceutical and biological products for long-term storage and extended shelf life employing a process that reduces the hydration level of the material to less than native hydration levels of the specific product. The invention further provides stabilized biological products, such as in the form of glassified beads, prepared using a two-phase system according to the described processes that may be rehydrated and prepared for clinical use, and having essentially no loss of biological and/or pharmacological activity.

  • Patent number: 6764539
    Abstract: A process for producing a hardenable composition with high storage stability containing scaly silica particles which consist essentially of foliar secondary silica particles and have a laminated structure, said process comprising: (1) a step of subjecting a silica sol, a silica hydrogel or hydrous silicic acid to hydrothermal treatment in the presence of an alkali metal salt to form tertiary agglomerated particles of the scaly silica in the form of porous three-dimensional disorderly agglomerates of foliar secondary silica particles, each secondary particle being formed by a parallel face-to-face alignment of a plurality of flaky primary particles which are overlaid one on another, and (2) a step of disintegrating and dispersing the tertiary agglomerated particles of silica in an organic polymer in the form of an aqueous emulsion by a wet method.

  • Patent number: 6660277
    Abstract: A cosmetic composition comprising a lipophilic clay gel and a hydrophilic clay gel. The two gels are combined or formed in situ to create a gel matrix. This matrix functions like an emulsion to deliver water and oil to the skin or other surface, but can be substantially free of surfactants, emulsifiers and waxes. A method for the preparation of a clay gel matrix is also revealed.
