Abstract

L'invention concerne un procédé de régulation, à une valeur fixée, de la température d'un bain liquide. On prélève du liquide dans ce bain et on l'y recycle en continu. Dès que la température s'écarte de la température fixée, on prélève également du liquide en discontinu, on le fait passer dans une enceinte maintenue à une température différente et on le mélange avec le liquide recyclé en continu. On arrive ainsi à réguler la température d'un bain avec une précision de l'ordre du vingtième de degré centigrade.
