US3811484A — Method and apparatus for delivering a predetermin…

Claim 1

Independent Claim 224 words

A method of dividing a predetermined quantity of a liquid present in a first container into two predetermined parts one of which remains in said first container and the other of which is delivered to a second container which comprises charging a first container with a predetermined volume of a liquid to be distributed, inserting into the first container a first leg of a generally U-shaped tubular pipe so that the open end of the first leg faces upward and is located at a predetermined distance from the bottom of the first container thus establishing a known quantity of liquid above the open end, inserting the second leg of the U-shaped pipe into a second container, creating a pressure differential between the containers such that the first container is at a higher pressure than the second so that said known quantity of liquid above the open end of said first leg is moved through the U-shaped pipe to said second container, said known quantity of liquid above the open end of said first leg being caused first to move downwardly through the leg of said U-shaped pipe and then to move upwardly through said leg the upwardly facing open end of said first leg limiting inaccuracy of measurement due to meniscus deformation when the known quantity of liquid is moved through said first leg.
