(under subclass 88) Systems in which a fluid flow is divided into a plurality of flow paths which are subsequently recombined, the ratio of the flows thus divided and recombined being controlled in response to a means sensing a condition to be maintained.
(1) Note. This subclass includes, for example, systems in which one of the plurality of flow paths pass through a means to treat the fluid to restore the property to be maintained, the amount of fluid passing through the treating means being controlled by the condition sensing means.
SEE OR SEARCH THIS CLASS, SUBCLASS:
599+, for systems involving dividing into parallel flow paths with recombining, without automatic control.
