Abstract:
The invention relates to a method of absorbing moisture and odour from a chamber, for example a waste receptacle. This is achieved by addition to the chamber of a desiccant composition comprising a substantially water-insoluble polyacrylate compound capable of absorbing at least its own weight of moisture, and an odour-combating zeolitic material.
Abstract:
The invention relates to a method of absorbing water vapour and malodour from a cavity, for example a drawer or wardrobe or the inside of a shoe. This is achieved by placement in the cavity of a package permeable to water vapour and retaining a particulate dehumidifying compound, a particulate odour-combating compound, and a filler comprising starch or a starch derivative or cellulose or a cellulose derivative, or which acts as a thickener or gelling agent for the water inside the package.
Abstract:
A method and device for the chemical conversion, filtration and/or purification of fluids water or other solutions containing microbiological and chemical contaminants, such as fluids containing arsenic, chlorine, bacteria, viruses, and cysts, where the fluid is passed through a purification material composed of fluid treatment carbon, metal phosphates, metal oxides, reduced metals, metal silicates, metal sulfates, metal carbonates, metal hydroxides, or combinations thereof. The material may be included in a fixed binder matrix.
Abstract:
To provide a refrigerating cycle apparatus which uses carbon dioxide as a working medium, in which a problem associated with reliability arisen from introduction of water into a refrigeration cycle has been solved.Carbonic acid produced by a reaction of carbon dioxide or a mixed refrigerant including carbon dioxide and water is efficiently removed by providing a flow channel of the refrigeration cycle with a carbonic acid trapping agent, and consequently, the refrigerating cycle apparatus with high reliability which can prevent deterioration of a carbon dioxide refrigerant, decomposition of a refrigeration oil, corrosion of metal components or the like is constructed.
Abstract:
Powdered compositions comprising in admixture inorganic salts and silica gel, and optionally a fragrance additive, are disclosed. The novel compositions are useful in absorbing and deodorizing liquid waste and for removing such waste from irregular surfaces, such as textiles and carpeting, as well as from smooth hard surfaces. The compositions are effective in absorbing liquid biohazards, such as blood, vomit, urine, and other body fluids. For this application, a halogen-containing compound, such as sodium hypochlorite or calcium hypochlorite is preferably included in the composition. The mixtures can also be utilized for the absorption of oil-based spills and hydrocarbons and are also effective in removing moisture and malodors associated with pet urine and other moisture-related stains encountered in the home. When applied to liquid wastes, the absorbent properties of the compositions contain the spill, creating a solid cohesive matrix that allows for easy disposal. Methods for removing liquid wastes are also disclosed.
Abstract:
Ammonia oxidation by passing a mixture of air and ammonia over a catalyst containing at least one cobalt compound at an elevated temperature wherein, prior to contact with the catalyst, the air is passed through an absorber comprising a support carrying an absorbent material for acidic gases.
Abstract:
The present invention discloses a new concurrent dialysate cartridge purification system for hemodialysis, particularly, a purification system whereby apatite and/or calcium phosphate and sodium polyphosphate are substituted for the standard zirconium oxide and zirconium phosphate, respectively. The concurrent dialysate cartridge purification system is comprised of multiple layers and at least one or more cation and/or anion exchange layer and at least one or more purification layer. One advantage of the concurrent dialysate cartridge purification system is the cost effectiveness of apatite and/or calcium phosphate and sodium polyphosphate.
Abstract:
A composition for removing hydrogen from an atmosphere, comprising a mixture of a polyphenyl ether and a hydrogenation catalyst, preferably a precious metal catalyst, and most preferably Pt. This composition is stable in the presence of oxygen, will not polymerize or degrade upon exposure to temperatures in excess of 200null C., or prolonged exposure to temperatures in the range of 100-300null C.
Abstract:
