Patent number: 9518181Abstract: A thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density is provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive to form a precursor material in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). This creates a network of voids located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural “hinges” that help stabilize the network and increase its ability to dissipate energy. The present inventors have also discovered that the voids can be distributed in a substantially homogeneous fashion throughout the composition.Type: GrantFiled: April 24, 2015Date of Patent: December 13, 2016Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Neil T.

Patent number: 9249651Abstract: Improved methods are provided for the application of downhole oil or gas well treating agents, such as liquid corrosion inhibition agents. The methods involve first lowering a liquid retainer device into a well casing, preferably at or above the location of the well production zone, followed by introduction of a liquid treating agent. The presence of the liquid retainer device prevents substantial passage of the agent into the production zone, and forms a column of the liquid agent above the device. The retainer device is then withdrawn from the well so as to create a substantially uniform film of the agent along the inner surfaces of the well casing. In this manner, proper coating of the casing is achieved while preventing production losses owing to passage of the treating agent into the production zone. The liquid retainer is preferably one or more swab cups or oil field retainers.Type: GrantFiled: May 28, 2013Date of Patent: February 2, 2016Assignee: Jacam Chemical Company 2013, LLCInventors: James C.

Patent number: 8268056Abstract: Disclosed is a method for manufacturing a separator. The method includes (S1) preparing a porous planar substrate having a plurality of pores, (S2) preparing a slurry containing inorganic particles dispersed therein and a polymer solution including a first binder polymer and a second binder polymer in a solvent, and sequentially coating the slurry on the porous substrate through a first discharge hole and a non-solvent incapable of dissolving the second binder polymer on the slurry through a second discharge hole adjacent to the first discharge hole, and (S3) simultaneously removing the solvent and the non-solvent by drying. According to the method, a separator with good bindability to electrodes can be manufactured in an easy manner. In addition, problems associated with the separation of inorganic particles in the course of manufacturing an electrochemical device can be avoided.Type: GrantFiled: December 20, 2011Date of Patent: September 18, 2012Assignee: LG Chem, Ltd.Inventors: Joo-Sung Lee, Jang-Hyuk Hong, Jong-Hun Kim, Bo-Kyung Ryu

Publication number: 20120125579Abstract: An antimicrobial coating slurry includes about 15.5 wt % of a wetting agent, about 6.0 wt % of an insolubilizer, about 1.1 wt % of a biocide agent, and about 7.8 wt % of an inorganic material that includes lithium oxide and the balance water. The slurry is applied to a heat exchanger surface, cured, and washed to form a hydrophilic coating that includes lithium silicate. The hydrophilic coating provides improved moisture wicking and a reduced dissolution rate of biocide, which is held within a lithium silicate matrix.Type: ApplicationFiled: January 31, 2012Publication date: May 24, 2012Inventors: Barbara M. Peyton, John W. Steele

Patent number: 8182866Abstract: The invention relates to a method of producing a substrate which is coated with a mesoporous layer and to the use thereof in ophthalmic optics. The inventive method comprises the following steps comprising: preparing a precursor sol containing (i) a precursor agent that is selected from compounds having formula M(X)4 (I), in which X is a hydrolysable group and M represents silicon or a tetravalent metal and mixtures thereof, (ii) at least one organic solvent, (iii) at least one pore-forming agent and (iv) water; depositing a film of the precursor sol on a main surface of the substrate; optionally consolidating the mesoporous structure of the deposited film; eliminating the pore-forming agent; and recovering the substrate coated with the mesoporous layer. The method is characterized in that: (i) the pore-forming agent is eliminated at a temperature of less than or equal to 150° C.Type: GrantFiled: May 3, 2005Date of Patent: May 22, 2012Assignee: Essilor International Compagnie Generale d'OptiqueInventors: Muriel Matheron, John Biteau, Jean-Paul Cano, Jean-Pierre Boilot, Thierry Gacoin

Patent number: 8119200Abstract: A method to prepare a flexible and breathable protective glove having excellent grip in both aqueous and oil environments includes coating an electrolyte treated glove liner substrate with a non-foamed dispersion of a polymeric material. The resulting semi-gelled polymeric coating which partially penetrates the depth of the glove liner substrate, is treated with a foamed solution of a surfactant, tenside or aerosol solution and the foam treated coating is overcoated with an electrolyte solution. In a resulting chemical or physical reaction, fine pores and cavities are formed in and on the polymer coating.Type: GrantFiled: April 23, 2009Date of Patent: February 21, 2012Assignee: Midas Safety Inc.Inventors: Mikhail Kassam, Akil Jaffer, Jamshed Amjad, Basheer Ali
