Patent number: 9273417Abstract: A versatile binder comprising at least one or more sulfopolyesters is provided. These sulfopolyester binders can enhance the dry tensile strength, wet tensile strength, tear force, and burst strength of the nonwoven articles in which they are incorporated. Additionally, the water permeability of these binders can be modified as desired by blending different types of sulfopolyesters to produce the binder. Therefore, the binder can be used in a wide array of nonwoven end products and can be modified accordingly based on the desired properties sought in the nonwoven products.Type: GrantFiled: October 14, 2011Date of Patent: March 1, 2016Assignee: Eastman Chemical CompanyInventors: Rakesh Kumar Gupta, Melvin Glenn Mitchell, Daniel William Klosiewicz, Mark Dwight Clark, Chris Delbert Anderson, Marvin Lynn Mitchell, Paula Hines Mitchell, Amber Layne Wolfe

Publication number: 20140060574Abstract: The present invention discloses new chamber clean chemistries for low temperature, gas phase, in-situ removal of fluorine doped tin oxide (FTO) films. These new in-situ cleaning chemistries will enable solar glass and low-emissivity glass manufacturers to improve the quality of FTO films produced, as well as reduce costs associated manual cleaning of FTO deposition systems. The end result is increased production throughput and better quality FTO films. This is achieved by using gas phase, in-situ cleaning molecules, such as, but not limited to, HI, CH3I, and HBr, in the FTO deposition chamber to remove unwanted buildup of FTO from chamber walls and components. Significant revenue can be derived from this customer benefit through molecule and technology solution sales related to in-situ FTO TCO chamber cleaning.Type: ApplicationFiled: September 3, 2013Publication date: March 6, 2014Applicant: MATHESON TRI-GASInventors: Carrie Wyse, Glenn Mitchell, Robert Torres, JR., Ramkumar Subramanian, Matt Shinriki

Publication number: 20140037575Abstract: Wild Game Drops is a soy wax drop impregnated with game animal liquid urine or fragrance oil. These drops are 100% biodegradable, non-toxic, environmentally safe and made from 100% dehydrogenated soy oil. The drops are used by a “hunter” as a wild game animal attractant or lure. The Wax is poured into a mold, frozen and released then bagged into individual bags for a no mess application. The drops can be placed anytime during the hunting process to allow the urine or fragrance oil to permeate into the air. The drops do not have to be melted as they will slowly release the scent as the day warms. Animals are attracted to the soy wax drops due to the different types of urine or fragrance oil used.Type: ApplicationFiled: August 6, 2012Publication date: February 6, 2014Inventors: Cheryl Lynn Mitchell, Robert Glenn Mitchell

Patent number: 8623148Abstract: Methods of cleaning a processing chamber with nitrogen trifluoride (NF3) are described. The methods involve a concurrent introduction of nitrogen trifluoride and a reactive diluent into the chamber. The NF3 may be excited in a plasma inside the chamber or in a remote plasma region upstream from the chamber. The reactive diluent may be introduced upstream or downstream of the remote plasma such that both NF3 and the reactive diluent (and any plasma-generated effluents) are present in the chamber during cleaning. The presence of the reactive diluent enhances the chamber-cleaning effectiveness of the NF3.Type: GrantFiled: September 9, 2010Date of Patent: January 7, 2014Assignee: Matheson Tri-Gas, Inc.Inventors: Glenn Mitchell, Robert Torres, Jr., Adam Seymour
