This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating.Type: GrantFiled: December 2, 2010Date of Patent: August 16, 2011Assignee: Baker Hughes IncorporatedInventors: Thomas J.

Patent number: 6503976Abstract: A coating composition for fabrics includes wetted microspheres containing a phase change material dispersed throughout a polymer binder, a surfactant, a dispersant, an antifoam agent and a thickener. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. To prepare the coating composition, microspheres containing phase change material are wetted and dispersed in a dispersion in a water solution containing a surfactant, a dispersant, an antifoam agent and a polymer mixture. The coating is then applied to a fabric.Type: GrantFiled: December 11, 2000Date of Patent: January 7, 2003Assignees: Outlast Technologies, Inc., R. H. Wyner Associates, Inc.Inventors: Joseph L. Zuckerman, Robert J. Pushaw, Bernard T. Perry, Daniel M. Wyner

Patent number: 6444738Abstract: Emulsions containing a hydrocarbon liquid in a continuous phase and alcohol and/or water in a dispersed phase. The emulsions are stabilized by an emulsifier and a coupling agent. The emulsifier is a copolymer containing at least one relatively hydrophobic polymeric block of styrene or ring substituted styrene monomer, and at least one relatively hydrophilic polymeric block of at least one monomer, such as ethylene oxide, selected from the group having the formula H(O—R)nOH where R is an aliphatic radical containing from 1 to 4 carbon atoms and n is a number between 20 and 300. The coupling agent is a copolymer containing at least one polymeric block of styrene or ring substituted styrene monomer, and at least one block being of a saturated or unsaturated aliphatic hydrocarbon moiety, such as butadiene. In order to stabilize the emulsion against stratification or breakage under heat soak conditions the coupling agent contains the styrene monomer and the hydrocarbon moiety in a weight ratio of from 1:0.Type: GrantFiled: February 2, 2000Date of Patent: September 3, 2002Assignee: Apace Research LimitedInventor: Russell Robert Reeves

Patent number: 6403686Abstract: Improved compositions of the present invention are made from a rubber latex component (A) and an oil carrier component (B) having hygroscopic and vulcanizing agents. Upon intermixing of the components A and B, an elastomeric composition is formed that can undergo a rheological transformation from a flowable liquid to a solidified elastomeric solid. An improved linear slope between fluidity and temperature is achieved by using naphthenic oil in the oil carrier component (B) with an organic rheology modifier, such as a modified castor oil and/or a polyamide. Further exemplary compositions comprise an inorganic rheology modifier such as an activated clay.Type: GrantFiled: April 11, 2000Date of Patent: June 11, 2002Assignee: W.R. Grace & Co. - Conn.Inventors: Matthew T. Pickett, Jay S. Kellett, Jianye Wen, David S. Hart
