  • Patent number: 10421654
    Abstract: A filling-element assembly for both pressurized and open-jet filling of containers includes a filling element having a filling-element housing, a liquid valve, a return-gas channel, and a seal. The housing has a fixed first segment, a vertically movable second segment, and an extendable segment between them to surrounds the valve housing in a fluid-tight manner. A return-gas channel extends along the filling-element axis between the valve housing and the filling-element housing. In a raised position of the second segment, the seal contacts the valve housing along a circumferential contact area and seals the filling-element discharge opening thereby forming a fluid-tight closure for the return-gas channel.

  • Patent number: 10415711
    Abstract: The invention relates to a mechanical energized sealing ball valve comprising a seat, a ball assembly, and a single valve stem that operates both the sealing member and the ball. The ball comprises a ball and a sealing member. The valve stem drives the ball to rotate between open position and close position. When the ball reaches the close position, the sealing member, operated by the same valve stem, moves away from the ball to press and sit against the seat. The invention has the advantages that: the valve has a compact structure, the friction-free on/off is achieved, the mechanical energized sealing force is even and reliable, the ball is retracted and locked in the opening position to protect against turbulence-induced damage, low operating torque, the open/close operation is rapid, and the valve stem seal operates simply and reliably.

  • Patent number: 10400955
    Abstract: A solvent storage and depressurization system is described. The system allows a volume of solvent to be stored and used at low pressure, thereby providing safety benefits and regulatory simplicity. The system includes an external expansion tank that is located outside of an extraction facility and that contains a solvent. The system also includes an internal storage tank that is located inside of the extraction facility and that provides a solvent supply to a solvent user, such as a phytochemical extraction system. The external and internal tanks are separated and connected via a duplex manifold. The manifold allows gas below a first pressure level to pass from the external expansion tank to the internal storage tank, and allows gas above a second pressure level to pass from the internal storage tank back to the external expansion tank, wherein the second pressure level is greater than the first pressure level.

  • Patent number: 10399845
    Abstract: A testable overfill prevention valve (“TOPV”) for a liquid storage container. The TOPV allows an individual to readily verify the operability of the TOPV. Preferably, a test member of directly contacts a portion of a latch to release a flow control member so that the flow control member can move from an open position to a closed position wherein in the closed position liquid is generally prevented from flowing out the TOPV. The test member preferably directly contacts the flow control member to move the control member to an intermediate position between open and closed positions allowing an individual looking down into the TOPV to see that the flow control member has moved sufficiently to confirm operability of the TOPV. Preferably, the test member is spring biased to a non-testing position and the entire test member is disposed in the housing of the TOPV when in a testing position.
