| 20140027384 | Apparatus and Methods for Controlled Release of Additive Compositions - Containers for controlled release of an additive composition into a liquid composition include a liquid impermeable casing having a hollow interior, at least one first opening, at least one second opening and at least one third opening, a liquid valve operable to allow a liquid composition to pass into the hollow interior across the liquid valve, an air valve operable to allow air to pass out of the hollow interior across the air valve and a membrane component secured to the casing. Methods of releasing additive compositions into liquid compositions are also provided. | 01-30-2014 |
| 20130255951 | Compositions, Systems and Methods for Releasing Additive Components - Compositions, systems and methods for the controlled and/or delayed release of chemical additive components into an aqueous fluid used in hydraulic fracturing of oil and/or gas wells. The chemical additive components may include a viscosity-reducing composition, an oxidizer composition, a pH modulating composition, a lubricant composition, a cross-linking composition, an anti-corrosion composition, an biocide composition, a crosslink-enhancing composition, and/or a combination of two or more of these compositions. Further embodiments include additives and methods of delivering a particle comprising an additive component to a desired site in an aqueous medium prior to release of the additive component into the aqueous medium. The coating is permeable, but insoluble in an aqueous medium, whereupon the additive components are released into the medium. | 10-03-2013 |
| 20120291869 | Systems and Methods for Releasing Additive Compositions - Systems and methods for releasing additive components into liquid media are provided. The systems include a plurality of coated items and a container holding the coated items. The container includes an insoluble material and a plurality of through holes through the material. The material covers an area of the container greater than the combined area of the through holes. | 11-22-2012 |

| 20090294725 | Controlled release cooling additive compositions - A controlled release additive composition for use in aqueous coolant systems is disclosed and comprises a core containing at least one additive component and a polymeric coating including one or more defined polymers substantially surrounding the core. The controlled released additive composition slowly releases the additive component into the aqueous coolant of an open, circulating cooling water system, thereby delivering an effective concentration level of the additive component over an extended period. | 12-03-2009 |
| 20090294379 | Controlled release of additive compositions - A container for releasing an additive composition into a liquid composition includes a liquid impermeable casing separate and apart from an internal combustion engine filter housing, and having a hollow interior, and at least one opening and a further opening into the hollow interior. The container further includes a structure operatively coupled to the further opening and operable to allow air to pass out of the hollow interior through the further opening and to substantially prevent a liquid composition from passing out of the hollow interior through the further opening. An additive composition is located in the hollow interior. At least one liquid permeable element, for example, a membrane member, is provided at or near the least one opening in the casing and is effective to provide for release of additive composition into the liquid composition. Methods of releasing additive compositions into liquid compositions are also provided. | 12-03-2009 |
| 20090294345 | Controlled release of microbiocides - A container for releasing a microbiocide component into a liquid composition susceptible to unwanted microbial growth (LCMG) includes a LCMG impermeable casing separate and apart from an internal combustion engine filter housing, and having a hollow interior and at least one opening. A microbiocide component, for example, at least one LCMG-soluble microbiocide, as the only active material located in the hollow interior. At least one liquid permeable element, for example, a membrane member, is provided at or near an opening in the casing and is effective to provide for release of microbiocide component into the LCMG.
