Abstract
Abstract Liquid proportioning apparatus that provides equalized hydrostatic pressure on two separate bodies of liquid and equalizes their temperature, throughout wide variations of pressure and temperature to which one of the liquids may be subjected, and that utilizes separate means for metering the two liquids in a predetermined ratio regardless of such variations in temperature and pressure, and with no moving parts. Accuracy of proportioning results from the use of hydrodynamically identical orifices (e.g., identical in both size and configuration) in separate metering means, the ratio of the number of such orifices in the separate metering means determining the proportioning of the liquids metered thereby. In specific embodiments for supplying medicated beverage to farm animals, a collapsible bag containing a concentrated medicament is at least partially submerged in water maintained under pressure so that the two liquids are in heat exchange and pressure equalizing relationship with each other. The medicament and water, at points thus substantially equalized in temperature and pressure, are separately metered from the bag and reservoir by hydrodynamically identical orifices and flow together to a drinking trough.
