摘要:
A method and apparatus removes carbon monoxide from hydrogen rich fuel by means of a catalytic material that preferentially adsorbs with carbon monoxide. The catalytic material is regenerated by an oxidizing agent that reacts with the carbon monoxide absorbed by the catalytic material. The reaction is initiated by an electrical current is generated either galvanically or electrolytically through the catalytic material.
摘要:
A process is described for reacting substituted N-alkoxy-2,6-dinitroanilines with a C.sub.1 -C.sub.3 alkyl halide, or a C.sub.3 -C.sub.4 alkenyl halide, in the presence of sodium hydride, to yield substituted N-alkoxy-N-substituted-2,6-dinitroanilines, which are active as herbicides.
摘要:
This invention relates to a metallic-second phase composites comprising a matrix of titanium aluminide with discrete titanium silicide particles dispersed therein. The second phase dispersoid is stabilized during the process of in-situ formation by the presence of zirconium.
摘要:
A new class of 2,6-dinitroanilines substituted on the anilino nitrogen with alkoxy and alkyl groups, which compounds are active as herbicides and plant growth regulators, and intermediates useful for the preparation thereof.
摘要:
Waste oils, fuels, and coolants contained in reservoirs and filters found in devices powered by electric motors and internal combustion engines are transferred from said reservoirs by a transportable pumping device in the form of an automotive fluids transfer machine, a shuttle, consisting of a parent tank and equipped to receive two auxiliary tanks, one for fresh filter oil and one for fresh filter fuel. The shuttle and auxiliary tanks are made of an oil and fuel resistant and leak proof material so that they can hold waste fluids until they are transferred to a shop's waste fluids disposal tank, without spills, threats to the environment, human contact with contaminating oil fuels or coolants, clean up costs, and lost time.
摘要:
Disclosed is a method of providing a thin copolyester coating on paper wherein the coating has good peel strength which comprises extruding a film of copolyester onto paper to form a coated sheet and passing the paper through a nip formed by a pair of cooperating chill and pressure rolls, wherein the copolyester consists essentially of repeat units from terephthalic acid, ethylene glycol, about 1.5-20 mol % of an aliphatic or cycloaliphatic glycol having 2 to 10 carbon atoms, and 0 to about 1.0 mol % of a polyfunctional branching agent. Also disclosed is the coated paper prepared by this method.
摘要:
Wet-laid sheets of softwood high yield fibers in combination with hardwood high yield fibers. The sheets, which are strong enough to be handled by commercial equipment, are formed on conventional papermaking machines using a furnish comprising a major proportion of softwood high yield fibers in admixture with a minor proportion of hardwood high yield fibers. The hardwood high yield fibers are specially prepared by a procedure comprising treating hardwood with relatively high levels of chemicals under relative stringent conditions and defibrating the treated hardwood with relatively high levels of power input. Airfelts made from these sheets exhibit low wet densities. Processes for making the sheets and the airfelts are also provided.
