  • Patent number: 10555618
    Abstract: 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.

  • Patent number: 10441917
    Abstract: 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.

  • Patent number: 8118886
    Abstract: A fuel mixture for fuel cells, comprising a gelled product containing at least a fuel and a gelling agent, in which reliquefaction for the fuel of the gelled product is brought about in the coexistence with a reliquefying agent; and a method of extracting a fuel for fuel cells, including: providing a gel structure in which a fuel is incorporated into a network structure of a gelling agent, with a reliquefying agent dispersed therein; adding a reliquefaction inducing agent to the gel structure to make the reliquefying agent break the network structure of the gelling agent, and thereby reliquefying and extracting the fuel.

  • Patent number: 6955638
    Abstract: 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.

  • Patent number: 5773706
    Abstract: 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.

  • Patent number: 5401341
    Abstract: 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.
