    摘要: A process for the preparation of aqueous thermosetting electrical insulating varnishes, wherein polyester-imide precondensates are prepared by condensing aromatic tricarboxylic acid monoanhydrides, diamines, diols, triols containing an isocyanurate ring, and cyclic trimerization products of diisocyanates, whose free isocyanate groups are blocked, with or without aromatic dicarboxylic acids or their esterifiable derivatives, and are reacted, at from 50.degree. to 200.degree. C., with or without addition of from 1 to 10% by weight, based on polyester-imide, of a polar organic solvent, with ammonia or an organic amine, and then diluted with fully demineralized water, with or without addition of a water-soluble curing catalyst. The novel electrical insulating varnishes are used as wire enamels or impregnating varnishes.

    摘要: The pressure chamber located in the sealing member is sub-divided by webs into a plurality of individual sub-chambers with restrictors between each sub-chamber and the barrier medium supply in order to obtain a uniform adjustment over the entire periphery of the gap between the sealing member and rotating part. Various types of means such as pressure-filled tubes are used to bias the sealing member from within a groove in the stationary part towards the rotatable part.
