Zusammenfassung:	911,464. Mixing fluids in flow. BRITISH PETROLEUM CO. Ltd., and DE HAVILLAND ENGINE CO. Ltd. March 23, 1961 [April 11, 1960], No. 12790/60. Class 86. [Also in Group XXIX] In a system for blending different fluids, two fluid control valves, Fig. 1 (see Group XXIX) are ganged together on a single operating shaft so that one opens as the other closes. It is stated that the system may be operated automatically by electromagnetic means responsive to any variation in the composition of the blended fluids. Circuit means may be incorporated for returning the valves to a mean position between successive blending operations.
