The closure device automatically releases gas and/or toxic vapor from the sealed vessel to protect the operator from harmful vapor without requiring the operator to manually actuate a valve or other mechanism prior to removing the vessel from the closure device. The closure device is constructed so the interior of the vessel can be pressurized while maintaining a pressure seal against the vessel opening, and the vessel can be cannulated without overpressurizing the vessel interior.

Abstract: A method and apparatus for preventing over-pressurization of vessel during filling with a fluid where temperature of the vessel would cause the fluid to flash or rapidly expand on contact. A shut off device is placed in a conduit between the fluid source and the vessel being filled, the shut off device including a flow control piston that is held in position to permit fluid flow. Fluid pressure from the displacement space in the vessel is provided on both end of the piston. When a condition of over-pressurization occurs in the vessel a rupture disc associated with one end of the piston fails and causes a depressurization on that end of the piston causing it to move to a position where further filling of the vessel is prevented. The piston is positioned by a buckling pin and can be reset after over-pressurization of the vessel is connected and filling can resume.

Abstract: In an apparatus for filling bottles with liquid, the liquid supply tank has several bottle filling adapters mounted to its body and providing a valve seat for liquid to flow from the tank to a bottle. The seat is proximate to a vertically movable valve body which has an integral tubular stem extending upwardly from it and a gas tube extending downwardly from it so gas can be conducted downwardly into a bottle and upwardly for being exhausted or returned to the tank. In the bore of the tubular combination gas conducting tube and valve stem there is a wire constituting a filling level probe. The tip of the wire is exposed in the gas tube to liquid in the bottle and the body of the wire is insulated and runs upwardly through the bore of the tubular stem where it is terminated in a cylindrical conductive element that enters an electrical connector. The connector provides a lead to a microprocessor based controller.

Abstract: A method and apparatus for drawing and measuring an amount of liquid agrichemical and dispensing the measured amount of agrichemical for mixture with water and eventual application onto a field. The agrichemical is drawn into a measuring vessel by suction pressure, created in one embodiment by an air compressor and valving system, and in another embodiment by a valve-pump in conjunction with a 3-way valve. The agrichemical is then dispensed from the measuring vessel either by positive pressure created by the same air compressor/valving system, or by suction pressure created by valve-pump/3-way valve. The valve-pump provides both a mixing chamber for the agrichemical and water prior to tank storage for eventual application, and controllable suction pressure for drawing the agrichemical out of the measuring vessel for mixing. The valve-pump is also self-cleaning thereby reducing the possibility of cross-contamination.

Abstract: An apparatus for filling containers, under counterpressure, with carbonated liquids. The return gas that is to be withdrawn from a container that is being filled is conveyed, accompanied by a pressure differential, into a return gas chamber via a connection that is provided with a flow control mechanism. In this return gas chamber a pressure is regulated that is adjustable within a range that is between the filling pressure and the critical pressure of the flow control mechanism. In this way, the flow velocity with which the dispensed liquid flows into a container that is being filled can be smoothly adapted in an infinitely variable manner to the filling characteristics of a respectively dispensed liquid, and/or to the respective output requirements of the filling apparatus.
