MEJORAS EN APARATO PARA ARMAR UN AGITADOR DE PALETAS SEPARABLE DENTRO DE UN RECIPIENTE PARA MEZCLAR INGREDIENTES CORROSIVOS Y MATERIALES SIMILARES

摘要

A separable blade agitator has a glass coated drive shaft and a glass coated impeller interference fitted to the end of the shaft in a gasketless, glass surface to glass surface joint. The interference fitting of the impeller to the shaft is accomplished by super cooling the end of the shaft with nitrogen or the like so that it can be inserted into a glass coated bore in the impeller.
