Patent number: 10555618Abstract: A mattress protector includes a composite sheet having a non-deformed length and a non-deformed width. The composite sheet includes a fabric and a water impermeable polymer. The composite sheet is capable of repeatedly stretching to a deformed length of at least 115% of the non-deformed length and returning to within 8% of the non-deformed length without rupture or permanent wrinkling of the composite sheet. Mattresses may be covered and protected by such a mattress protector. Methods of forming mattress protectors include providing a water impermeable polymer on a fabric so as to form a composite sheet having a non-deformed length and a non-deformed width, and formulating and configuring the composite sheet so as to be capable of repeatedly stretching to a deformed length of at least 115% of the non-deformed length and returning to within 8% of the non-deformed length without rupture or permanent wrinkling of the composite sheet.Type: GrantFiled: September 21, 2016Date of Patent: February 11, 2020Assignee: Purple Innovation, LLCInventor: Tony M.

Patent number: 10441917Abstract: Provided is a method for separating, from a raw gas containing a specific gas, the specific gas using a gas separation membrane module. The gas separation membrane module includes a housing and a gas separation membrane element enclosed in the housing. The gas separation membrane element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for permeation of the specific gas. The method includes the steps of: increasing pressure in an interior of the gas separation membrane module; increasing a temperature in the interior of the gas separation membrane module; and feeding a raw gas to the interior of the gas separation membrane module in that order.Type: GrantFiled: September 13, 2018Date of Patent: October 15, 2019Assignees: SUMITOMO CHEMICAL COMPANY, LIMITED, RENAISSANCE ENERGY RESEARCH CORPORATIONInventors: Takenori Kitaura, Hisaaki Miyamoto, Yudai Ota, Takehiro Nakasuji, Osamu Okada, Masaaki Teramoto

Patent number: 6955638Abstract: A process for disposing of solvent-containing liquids so that they do not contaminate ground water. An absorbent blend is mixed into a water-containing solvent mixture at the rate of about 1 lb. of blend per gallon of liquid. The blend is made up of a swellable polymer, consisting of polyacrylamide/polyacrylate co-polymer salt or poly 2-propenamide-co-2-propenoic acid homopolymer salt which swells and absorbs liquid. The blend also contains a mixture of solid absorbents. The resulting mixture is stirred in the container until it becomes thick and then it is allowed to set to provide a disposable modeling clay-like solid. The resulting solid material, after curing, may be then simply added to solid trash, and thus, be freed from contaminating ground water.Type: GrantFiled: May 6, 2003Date of Patent: October 18, 2005Inventors: Don C. Atkins, Steven H. Bortz

Patent number: 5773706Abstract: Organic liquids can be very effectively gelled by using in combination with an amine neutralized anionic polymer an auxiliary rheological additive. The auxiliary rheological additive is a substance which increases the linearity of the anionic polymer and its thixotropic properties. Suitable auxiliary rheological additives are amphoteric oxides and/or fatty acids and/or fatty acid salts. The organic liquids that can be effectively gelled are organic solvents which include fuels such as hydrocarbons and alcohols.Type: GrantFiled: January 28, 1997Date of Patent: June 30, 1998Assignee: Candle Corporation of AmericaInventors: John N.

Patent number: 5401341Abstract: This invention relates to water-in-oil emulsion explosives in which an oxidizing material is contained in the discontinuous water phase, and the continuous oil phase acts as a carbonaceous fuel. More particularly, this invention relates to such explosives in which polyfunctional carboxylic acids, sulfonic acids, or phosphorous-containing acids, soluble in the oil phase, are caused to cross-link using an inorganic cross-linker, thereby causing the viscosity of the emulsion to increase.Type: GrantFiled: January 19, 1994Date of Patent: March 28, 1995Assignee: The Lubrizol CorporationInventors: John W.
