Patent number: 8109287Abstract: A container (1) for releasing a chemical additive (7) in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing (3) having a hollow interior and an additive composition (7) comprising at least one fluid material-soluble additive. The additive (7) is held within the container (1) by a least one fluid material-permeable element (11) provided at or near an opening (13) in the casing (1) and is effective to provide for release of additive(s) (7) into the fluid material. Methods of releasing additives (7) into fluid material are also provided.Type: GrantFiled: July 22, 2009Date of Patent: February 7, 2012Assignee: Cummins Filtration IP, Inc.Inventors: Harold R. Martin, Dennis Kelly, Joseph C. Drozd, Thomas J. Blakemore, Doug Hudgens, Barry M. Verdegan

Patent number: 7524434Abstract: Methods of treating aqueous coolants in open circulating water cooling tower systems are provided. The methods including placing a controlled release additive composition in contact with an open circulating aqueous coolant in an open circulating water cooling tower system. The controlled release additive composition includes a core having at least one additive selected from corrosion inhibitors and scale inhibitors; and a coating, for example, a polymeric coating, substantially surrounding the core. The coating is substantially insoluble in the aqueous coolant, and is effective to slow the release of the at least one additive into the aqueous coolant.Type: GrantFiled: August 31, 2004Date of Patent: April 28, 2009Assignee: Dober Chemical CorporationInventors: Thomas J. Blakemore, Yu-Sen Chen

Patent number: 7001531Abstract: A coolant additive composition comprising a sustained release component and an additive component, the additive component is effective to provide at least one benefit to a coolant when released into the coolant, the sustained release component includes a polymeric material and is effective to reduce the rate of release of the additive component into the coolant relative to an identical composition without the sustained release component.Type: GrantFiled: August 24, 2001Date of Patent: February 21, 2006Assignees: Dober Chemical Corp., FleetGuard, Inc.Inventors: Yu-Sen Chen, Doug Hudgens, Thomas J. Blakemore, Joseph C. Drozd

Patent number: 6878309Abstract: A controlled-release additive composition for use in aqueous systems. The composition comprises a core containing at least one additive component and a polymeric coating encapsulating said core. The controlled released cooling additive composition slowly releases the additive components to aqueous system, thereby delivering an effective concentration level of additive components over an extended period.Type: GrantFiled: February 12, 2001Date of Patent: April 12, 2005Assignee: Dober Chemical Corp.Inventors: Thomas J. Blakemore, Yu-Sen Chen

Patent number: 6827750Abstract: A container for releasing a chemical additive into a fuel composition comprises a fuel-impermeable casing having a hollow interior and an additive composition comprising at least one fuel soluble additive. The additive is held within the container by at least one fuel-permeable element provided at or near an opening in the casing and is effective to provide for release of additive(s) into the fuel composition. Methods of releasing additives into fuel compositions are also provided.Type: GrantFiled: August 24, 2001Date of Patent: December 7, 2004Assignees: Dober Chemical Corp, Fleetguard, Inc.Inventors: Joseph C. Drozd, Harold R. Martin, Thomas J. Blakemore, Dennis Kelly, Doug Hudgens

Publication number: 20030218150Abstract: A chemical composition and method of deployment into a coolant or coolant systems to provide at least one benefit to the system. The additive compositions includes a silicate component and a silicate stabilizer, the compositions being in the form of a solid, a non-flowable semi-solid or a flowable semi-solid which is dissolved into a coolant and enters the cooling system so as to provide at least one benefit to a coolant system when released, for example, to protect an engine. The method of deployment into the coolant and subsequently the cooling systems includes injecting or dissolving the additive into the coolant, forming the additive to the housing of the system or forming the coolant to the filter located in the housing of the cooling system.Type: ApplicationFiled: February 26, 2003Publication date: November 27, 2003Applicant: Dober Chemical CorporationInventors: Thomas J. Blakemore, Yu-Sen Chen, Heather Michalesko

Patent number: 6607694Abstract: A controlled-release coolant additive composition for use in engine coolant systems comprising a core containing at least one coolant additive component and a polymeric coating encapsulating said core. The controlled released coolant additive composition slowly releases the coolant additive components to an engine coolant system, thereby delivering an effective concentration level of coolant additive components over an extended period. The controlled-release coolant additive composition maintains a minimum concentration level of active coolant additive components in the coolant system.Type: GrantFiled: March 31, 2000Date of Patent: August 19, 2003Assignee: Dober Chemical Corp.Inventors: Thomas J. Blakemore, Yu-Sen Chen

Publication number: 20030122104Abstract: A liquid replacement system is provided for introducing additives to an open recirculating system or a closed loop boiler water system in a controlled manner. The liquid replacement system comprises a make-up line and an additive system disposed therein. A make-up liquid enters into the make-up line where the additive system is structured to provide a controlled release of an additive to the make-up liquid, and the make-up liquid carries the additives into the open recirculating system or a closed loop boiler water system. The liquid replacement system allows for controlled release of additive components to the open recirculating system or the closed loop boiler water system, thereby delivering an effective concentration of additive components over an extended period.Type: ApplicationFiled: February 12, 2003Publication date: July 3, 2003Applicant: Dober Chemical CorporationInventors: Thomas J. Blakemore, Yu-Sen Chen, Dennis Kelly
