Abstract: A liner for aircraft fuel tanks which limits the amount of fuel that can be spilled in the event of a crash. The liner is made of neoprene rubber with nylon reinforcing threads or other light-weight flexible material and is suspended within the fuel tank from a frame or from the tank itself. In normal operation the liner in effect floats in the fuel and is not subject to major stresses during flight since it does not carry the weight of the fuel. The liner can be retrofitted into existing aircraft with only minor modifications to the internal hardware in the tanks. It includes a valve in its discharge port that is either fully open for normal use, or is fully closed by the pilot when a crash is inevitable. The entire system (i.e. liner, frame, valves, etc.) is very small and lightweight, thereby adding minimal weight and fuel capacity loss penalties. The system can reduce the spillage from a ruptured wing tank by as much as 98%.

Abstract: A fuel delivery system for vehicles with more than one fuel tank or a single tank with separate sections under at least some fuel level conditions. The system has an electric fuel pump disposed in the fuel container and a jet pump connected to the electric fuel pump with fuel pickups connected to the jet pump through a siphon. The electric fuel pump powers the jet pump to fill the siphon with liquid fuel and draw fuel through the pickups which are spaced apart in separate sections of the fuel container. When the siphon is completely filled with liquid fuel and the jet pump is operating, any difference in the heads or fuel levels in the sections of the fuel container will cause fuel to flow through the siphon from the section with the greater head to the other section of the tank. This flow, due to the difference in pressure associated with different fuel levels, continues until the fuel levels and, hence, the pressures are substantially the same in each section of the container.

Abstract: A fuel vapor recovery system has a control valve that is solenoid operated by a fuel filler pipe access door to control fluid communication between a fuel tank and a fuel vapor storage canister. The fuel tank includes a refueling valve that is open when the fuel tank is being refueled to provide a large unrestricted flow passage to the canister via the control valve. The refueling valve closes or restricts gas vapor flow at a predetermined fuel fill level in the tank to create a dome pressure, that is, a pressurized volume of gas in the space at the top of the tank above the fuel. This dome pressure causes the fuel level to rise in the filler pipe and automatically shut off the fuel filler nozzle in a well known manner. The fuel tank also has vent valves that provide restricted flow passages to the canister via the control valve for ordinary emissions of fuel vapors from the fuel tank.

A reliable filling of the vessel with fuel is ensured in spite of the compact construction even when the tank is almost empty and under unfavorable operating conditions in that jet pumps connected in parallel to the line system are arranged at a common structural member and in that a suction line leads to each mixing tube, the openings of these suction lines remote of the structural member being situated in the tank at a distance from one another.

Abstract: In a fuel pump inlet chamber assembly having a communication passage which allows ejection of fuel from the fuel pump inlet chamber to the remaining part of the fuel tank only at a limited flow rate so that any short-term change in the fuel level due to the motion of the fuel inside the tank may not substantially affect the availability of fuel inside the fuel pump inlet chamber, the fuel pump is conveniently interposed in the interface between these two parts, thereby not only simplifying the assembling work but also allowing easy access to the fuel pump for servicing purpose. This takes advantage of the fact that the fuel pump inlet chamber is normally made of molded plastic material, and is required to be constructed from two pieces, i.e., the main body and the lid member. Thus, the fuel pump inlet chamber assembly can be made simple in structure and easy and economical to fabricate while allowing easy access to the fuel pump.

Abstract: Existing devices for controlling flow in water and wastewater treatment systems utilize mechanical valves, adjustable height weirs and gates which are expensive to manufacture and maintain, and in some circumstances such as during winter, difficult to operate. A relatively simple substitute for such devices to control the flow from one zone or area to another includes a casing defining a weir chamber, a submerged weir in the chamber, an inlet on one side of the casing for introducing liquid into the chamber, a liquid outlet from the chamber on the other side of the weir, connected to a second zone or area at a flooded level below the liquid level in the second zone or area, and a duct in the casing for introducing gas under pressure into and out of the chamber for actively controlling the liquid level in the chamber and consequently the flow of liquid over the weir between the inlet and outlet. The use of the above described apparatus involves a novel method of controlling the flow of liquid over a weir.

Abstract: A fuel feeder for an automotive engine, which comprises a fuel tank with a sub-tank provided therein for feeding fuel from the sub-tank to an engine. Excess fuel returned from the engine is led to an overflow chamber disposed in the sub-tank and thence overflows into the sub-tank. Normally, the overflow chamber is thus full of returned fuel. When the fuel in the sub-tank is brought to one side due to a sudden acceleration or deceleration or a turning of the vehicle, the fuel in the overflow chamber is also brought to the same side and overflows from the overflow chamber, thus increasing fuel in the sub-tank.
