Abstract: A container filling device is provided for filling a container with desired headspace. The container filling device includes a siphon and a funnel having a bottom region configured to engage a container. The siphon extends through an opening in the bottom region and a sidewall such that a first end of the siphon has a first elevation and a second end of the siphon has a lower elevation than the first elevation. The bottom region is provided with an opening for the outflow of liquid from the receiving area into the container. Excess liquid flowing into the container beyond a desired headspace escapes from the container through the siphon. A liquid filler system can be provided with a frame, a plumbing system, and an alignment system for engaging and disengaging the container filling device with the container.

Abstract: An apparatus for transferring a fluid from a supply container to a desired receptacle. The apparatus includes a conduit having a fluid passage with a valve seat and a flexible containment member. A moveable sealing member is coupled to the flexible containment member and is configured for sealingly engaging the valve seat. An activator is coupled to the sealing member for displacing the sealing member from the valve seat to effect the creation of a reduced fluid pressure in the fluid in the supply container.

Abstract: A method and apparatus for dispensing biological fluids. The system may provide supply (stock) vessels of refrigerated biological fluids that remain connected to dispensers as the dispensers are operated to distribute the biological fluids to receiver vessels. Each receiver vessel may be engaged selectively with a suitable set of one or more dispensers to select the type and amount of biological fluid to be dispensed to the receiver vessel. The dispensers may be configured to permit the biological fluids to be selectively dispensed to receiver vessels under sterile conditions, so that the biological fluids may remain in a substantially closed environment as they are transferred between vessels.

Abstract: A fuel-recovery system for removing fuel from a fuel tank having a filler neck and a rollover valve is disclosed. A fuel-recovery line has one or more holes in its outside wall and a tapered plug in its inlet end. The fuel-recovery line also has a bend in its inlet end to facilitate its passage past the rollover valve. The fuel-recovery line passes through a pressure cap that is sealed to the filler neck of the fuel tank. A source of gas is connected to a gas line that connects to the pressure cap for pressurizing the fuel tank.

Abstract: A joint for a fluid pumping apparatus includes a body having a passage defined in the body and extending through the body. A through hole is longitudinally defined in the body and extends through the body. A container is mounted to a lower end of the body, and the passage and the through hole communicate with the interior of the container. A connecting seat in mounted to an upper end of the body and has hollow connector communicating with the through hole in the body. A hose has a first end connected to the hollow connector and a second extending into a pail containing fluid. Consequently, the fluid in the pail can be sucked into the container when a compressed air flows through the passage in the body.
