| 20100204082 | Alkaline compositions and methods of producing same - Compositions, such as alkali builder compositions for the laundry industry, are provided and include water, an alkali metal hydroxide component, a chelating component and a hydroxyethyliminodiacetic acid (HEIDA) component. Methods for producing such compositions are also disclosed. | 08-12-2010 |
| 20090304868 | Controlled release cooling additive composition - Controlled release potability additive compositions for use in potable water systems include a core containing at least one potability additive component and a polymeric coating. Controlled release systems for releasing potability additive components into potable water systems are also provided. Methods of using such compositions and systems to benefit potability of water in potable water systems, for example, drinking water systems, are disclosed. | 12-10-2009 |
| 20090301968 | Devices 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 opening and a membrane component secured to the casing. Methods of releasing additive compositions into liquid compositions are also provided. | 12-10-2009 |
| 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. Methods of releasing microbiocide component into LCMGs are also provided. | 12-03-2009 |
| 20090283466 | CONTROLLED RELEASE OF ADDITIVES IN FLUID SYSTEMS - A container ( | 11-19-2009 |
| 20080296234 | 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 housing, and having a hollow interior and at least one opening. A microbiocide component, for example, at least one LCMG-soluble microbiocide, is located in the hollow interior. At least one LCMG-permeable element is provided at or near an opening in the casing and is effective to provide for release of microbiocide component into the LCMG. Methods of releasing microbiocide component into LCMGs are also provided. | 12-04-2008 |
| 20080223414 | Compositions and methods for removing titanium dioxide from surfaces - Compositions for removing titanium dioxide-containing materials located on a surface of a piece of process equipment generally include an aqueous carrier and a polycarboxylic acid component in an amount effective to provide the composition with an acidic pH in a range of between about 4.0 to about 5.0. The compositions are effective to provide enhanced removal of titanium dioxide containing materials from a surface when the surface are contacted with the compositions when the compositions are at relatively low temperatures. | 09-18-2008 |
