Abstract
A method and apparatus for producing from two different liquid input streams which are at different temperatures, a single output stream with a selectable, low-thermal-noise, regulated temperature which is intermediate the input streams' temperatures. The invention operates with successive, recurrent, fixed-length operating cycles, during each of which a variable-length pulse of liquid from each stream, exclusively, is permitted to flow. Temperature monitoring of the resulting blended output stream effects continuous adjustment of the respective pulse-lengths (or duty cycles) of such alternate differing-temperature pulses to maintain the desired regulated temperature.
