Abstract

Perfeccionamientos en dispositivos de inyección de un gas en un líquido, por medio de tubos de pequeño diámetro interno, inferior a 2mm, y de longitud al menos 20 veces la del diámetro, escapándose el gas en forma de burbujas de sus porciones extremas libres en el líquido, siendo estas extremidades tales que puedan estar animadas de un ligero movimiento bajo la influencia de la inyección del gas en el líquido y de las corrientes provocadas por esta inyección, *** Ver imagen
