Gas sensor

A catalytic composite for deodorizing odorous gases is provided. The composite comprises: ceramic fibers; zeolite supported on the surface of and in the interstices between the ceramic fibers; and gold and an iron oxide both supported mainly on the zeolite; the catalytic composite being so formed as to allow a gas to pass therethrough.

A pressure cooker and a process for making the same, wherein the pressure cooker includes a pressure container for accommodating food to be cooked, a lid for covering the container in an airtight manner, a pressure control device for adjusting the internal pressure in the container, wherein the container or the lid or both are partly or wholly made of a composite resin consisting essentially of polyphenylene sulfide resin and 30 wt % to 50 wt % glass fiber.

Pressure cooker

This invention provides a catalytic composite for decomposing fats and oils, and a heating cooker having the catalytic composite mounted therein. The catalytic composite comprises a porous sheet made of ceramic fibers and/or metal fibers, and a catalyst. The catalytic composite is capable of decomposing oil grease or stains deposited on the inner wall of a heating cooker and cooking exhausts emitted in the process of cooking by oxidation, at relatively low temperatures.

A coating composition for solar selective absorption comprising, in solvent, particles of an inorganic black pigment dispersed in a dissolved binder of a thermosetting acrylic resin and particles of a low molecular weight fluorocarbon resin contained in an amount of 5-15 parts by weight per 100 parts by weight of the acrylic resin. The inorganic black particles have a size of 0.01-0.5 microns and are contained in an amount of 45-65 parts by weight per 100 parts by weight of the acrylic resin. An article having a metal substrate and a paint film formed thereon from the composition in a dry thickness of 1.5 microns or more is also described.

Method for removal of carbon monoxide from air wherein air to be purified is passed through a catalyst for promotion of oxidation of carbon monoxide consisting of a carrier including powdered activated carbon, an alkali, and a bonding agent and inpregnated with palladium alone or in combination one or more of the elements ruthenium, rhodium, and platinum. The amount of included alkali is made such that there is reduced risk of combustion due to presence of activated carbon, and the bonding agent renders the catalyst more resistant to vibration, while high rates of carbon removal are achieved at comparatively low temperature and high rates of air flow through the catalyst.

Method for purification of air containing carbon monoxide

In removing nitrogen oxide from a gas containing it, the gas is passed through a region where at least one of calcium sulfate and calcium hydroxide coexists with powerful oxidation agents such as sodium chlorite, potassium permanganate, etc. thereby removing the nitrogen oxide, mainly nitrogen monoxide, from the gas. This method is very effective in purifying exhaust gases resulting from burning operations, since 80 to 90% or more of the nitrogen oxide contained in the exhaust gases is nitrogen monoxide. In addition, this method is also effective in purifying indoor air.

Gas-purifying composition and method of producing it

Nitrogen oxides removal method wherein nitrogen oxides are removed from a gas by bringing the gas into contact with a granulated material containing an alkali and cement material, active carbon and a binder. The active carbon promotes an absorption reaction between the alkali material and nitrogen oxides, the cement material provides a porous but strong structure to the material, and the binder permits longer use of the material in a wide range of conditions.
