Abstract: A mixing device includes a base, shaft, impeller sleeve, and impeller blades. The base can be constructed for releasable attachment to an opening of a container, such as a 55-gallon drum. The shaft extends from the base and is coupled thereto such that rotation can be transmitted to the shaft by way of or through the base. The impeller sleeve is mounted on the shaft and supports the impeller blades. Each impeller blade includes an attachment leg and a stirring leg extending from the attachment leg. The impeller blades are supported so as to transition from a collapsed position with the stirring leg proximal to a central axis of the shaft to an extended position with the stirring leg distal from the central axis when the shaft is rotated. Each impeller blade can be formed of a plastic, such as a glass-filled polypropylene or glass-filled nylon.

Abstract: The invention comprises a containerization system for packaging water soluble bags containing a hazardous chemical such as an agrochemical. The bags are placed in pairs wrapped in an overwrap in a vertical position inside an inner triangular shipping cell of an outer container.

Abstract: A subaqueous sequence valve mechanism includes one or more main valves each adapted to be disposed in the water below the surface thereof. A first expansible chamber hydraulic actuator on the main valve operates that valve and also operates a second expansible chamber device against a spring. A hydraulic pressure line or lead from a controlled source above the surface is joined to and controls the submerged actuator. The second expansible chamber is connected in sequence through a throttle valve and a pressure relief valve to one side of a movable barrier in a hydraulic accumulator. On the other side of the movable barrier the accumulator is open to the water. There is also a return, one way flow valve shunting the pressure relief valve. The accumulator is hydraulically protected by a spring loaded check valve discharging into the water.
