초록

A control system for providing a closed loop control circuit between a liquid nitrogen dispenser and apparatus for determining internal pressure within a closed can having liquid nitrogen applied thereto whereby the automatic controlling of the volume of liquid nitrogen dispensed into each can is effected. Control data from a pressure test unit is averaged and the average is compared to a preselected set point and converted into a pulse of a width varying in accordance with the average detected pressure of previously filled cans to control the time of di...

청구항

A method of controlling the delivery of an inert gas under pressure into a container which is thereafter sealed and has an internal pressure, said method comprising the steps of providing a tank having therein an inert gas in liquid state with there being a discharge opening in a bottom wall of the tank controlled by valve means having an electromechanical actuator, utilizing the valve means to controllably dispense the liquid inert gas into open filled containers passing beneath the tank, closing the containers in sealed relation, testing the closed con...
