摘要： A process for the production of chlorine dioxide by reacting in a reaction vessel an alkali metal chlorate, mineral acid and a reducing agent in such proportions that chlorine dioxide is produced in a reaction medium which is maintained at a temperature of from about 50.degree. C. to about 100.degree. C. and at an acidity within a range of from about 5N to about 11N. The reaction medium is subjected to subatmospheric pressure sufficient for evaporating water, a mixture of chlorine dioxide, oxgen and water vapour being withdrawn from an evaporation zone in the reaction vessel, and alkali metal sulfate being precipitated in a crystallization zone in the reaction vessel. As the reducing agent hydrogen peroxide is used.

摘要： A process for the production of essentially chlorine free chlorine dioxide whereby a flow of chlorine dioxide obtained from reduction of alkali metal chlorate and containing by-product of chlorine gas is absorbed in water and the chlorine gas is treated with formic acid in the water solution. The formic acid is added in an amount resulting in a mole ratio formic acid to chlorine gas of >1:1.

摘要： The present invention relates to a method for mounting magnet elements on the surface of a rotor for use in a permanent magnet motor. The method comprises the steps of : providing a first tube like element, wherein said first tube like element has an inner diameter that corresponds to an outer diameter of said rotor, providing a second tube like element, wherein said second tube like element has an inner diameter that is larger than an outer diameter of said first tube like element, inserting said first tube like element into said second tube like element, in order to create a hollow space between them, inserting a number of magnet elements into said hollow space, and inserting said rotor into said first tube like element, whereupon said magnet elements are in a tight fit arrangement between said first tube like element and said second tube like element.

摘要： A process for the production of chlorine dioxide by reacting in a reaction vessel an alkali metal chlorate, mineral acid and a reducing agent in such proportions that chlorine dioxide is produced in a reaction medium which is maintained at a temperature of from about 50.degree. C. to about 100.degree. C. and at an acidity within a range of from about 2 to about 11N and which is subjected to subatmospheric pressure sufficient for evaporating water. A mixture of chlorine dioxide and water vapor is withdrawn from an evaporation zone in the reaction vessel, and alkali metal sulfate is precipitated in a crystallization zone in the reaction vessel. Straight chained alcohols with the formula CH.sub.2 OH(CHOH).sub.n CH.sub.2 OH where n=0-5, are used as reducing agents. Preferred reducing agents consist of glycol or glycerol. The reaction may also be performed in the presence of a catalyst.
