672,326. Distributing liquids. S. U. CARBURETTER CO., Ltd. Nov. 9, 1950 [Jan. 18, 1950], No. 1293/50. Class 21 [Also in Groups XI, XXVI and XXIX] The volumetric rates of flow of liquid streams under approximately the same head and derived from a single source are equalized by rapidly transposing portions of the respective streams in a continuous manner without interrupting the flow in any of them. In Fig. 1, a rotor 2 with two diametrically opposed ducts 3, 4 is rotatably supported in a casing 1 by a spigot 6 and a continuously driven shaft 5 and is urged against the facing 11 of the end wall 8 by a spring 10. Liquid is supplied through an inlet 14 and is discharged in two equal streams through outlets 15, 16. The outlets 15, 16 communicate with arcuate grooves 12, 13 in the facing 11. The ends of the grooves 12, 13 are sufficiently close to be bridged by the ducts 3, 4. The arcuate grooves may alternatively be in the adjacent end face of the rotor. More than two rotor ducts may be provided to increase the degree of accuracy of flow-equalization or to enable the same accuracy to be obtained at a lower rotor speed. Such accuracy is increased by increasing the rotor speed or lengthening, the rotor ducts. The latter need not be straight and may be of coiled or labyrinthine form. In Fig. 4, the supplies of liquid fuel through pipes 24, 25 to the spill burners 26, 27 of a gas turbine fuel system (see Group XXVI) are equalized by a flowequalizing device E1 similar to that shown in Figs. 1 and 3.
