  • High pressure lubrication system
    Patent number: 8714309
    Abstract: An improved lubrication system for use in connection with high pressure processing and particularly useful for LDPE processing. The lubricating system utilizes flow meters to monitor and control the supply pressure and oil flow to a machine lubrication point. Furthermore, two different types of oil may be used so as to alleviate down time and repair often associated with use of food grade oil as the lubricate for the camshaft and other working components of the lubrication system.
    Type: Grant

  • Flow control system
    Patent number: 4420044
    Abstract: A control valve for a passageway in which the valve is reciprocated toward and away from its seat by pressure within a pressure dome and pressure exteriorly of the valve housing and in which reciprocation is controlled by a J-slot capable of latching the valve in open position while being run and releasing the valve for reciprocation after being landed in the well together with a frangible disc which may be ruptured to permit flow past the valve member; said valve being used to control flow through a H mandrel in a pumpdown system.
