Abstract: An oil-sorbing filter element for removing oil from an aqueous flow such as the bilge water of a watercraft. The element includes a first stage which is formed of a consolidated permeable mass of a oleophilic polymeric material such as styrenic mid-block copolymer.

Abstract: A shut-off valve for use in a filtration system with a filter element having a tubular coupling member at one end arranged so that when the filter is installed in the system the coupling element extends into a tubular housing to displace a spool to thereby permit flow through the filter element, the spool being returned by a compression spring to a closed position within the housing to shut off flow when the filter element is removed, the tubular housing having a pair of spaced apart internal sealing faces and the spool having a matching pair of spaced apart sealing surfaces that close against each other when the spool is in the closed position to thereby prevent flow through the valve. The valve is arranged in such a way that when in the closed position fluid pressure applied to the valve exerts force on the spool to urge it more tightly into the closed position.

Abstract: A system for dispensing liquid fuel to a motor vehicle fueling station in which fuel from an underground storage tank is pumped to the motor vehicle fueling station and in which the underground storage tank has a vertical riser pipe extending upwardly therefrom through which fuel is pumped, the system including a vessel having a partition therein dividing it into an upper and a lower zone, the vessel being removable attached to the riser pipe and providing closed communication between fuel pumped from the underground storage tank into the vessel upper zone, one or more filter cartridges positioned in the vessel upper zone and having communication through the filter cartridges into the vessel lower zone, a removable lid closing the vessel top, fuel flowing from the storage tank passing upwardly through the riser pipe and into the interior vessel upper zone, through the filter cartridge and into the vessel lower zone and through an outlet opening communicating with the vessel lower zone and through piping to a

Abstract: A liquid fuel dispensing system with improved means of preventing water and particulate contamination employing an underground fuel storage tank, a pump for moving fuel from the fuel storage tank to a pump fuel outlet, an underground enclosed sump in which at least a portion of the pump is located, a filtration vessel within the sump having a fuel inlet connected to the pump fuel outlet and a fuel outlet, a filter element in the filtration vessel in series with fuel flow therethrough, the filter element having a filter media which intercepts particulate contaminants and which absorbs water to thereby prevent particulate and water contaminants from passing therethrough, a fuel shut-off device in conjunction with the filter element which is moved to the closed position when a predetermined pressure differential develops across the filter media as water is absorbed, the shut-off device serving to, upon actuation, completely block the flow of fuel through the filter element.

Abstract: A fuel filter for preventing water and particulate contamination from passing therethrough, the filter having a rigid tubular fuel previous member having a first end and a second end, a flexible filter media surrounding the tubular member through which fuel freely passes from the exterior thereof into the tubular member but which resists the passage of particulate matter and water, a first end cap secured to the tubular member first end having an integral projectile portion extending within the tubular member direction toward the tubular member second end, the projectile portion being severable from the first end cap when differential fuel pressure thereacross reaches a preselected level, and, when severed, a passageway is formed through the first end cap, a second end cap secured to the tubular member second end having a passageway therethrough and having an annular seating surface, the projectile portion being configured to, when severed from the first end cap, engage and close against the annular surface o

Abstract: A coalescing plate packing system for use in separating immiscible components of different densities mixed in a fluid, the packing system being used in a vessel having a fluid inlet, a lighter component outlet and a heavier components outlet, the packing system being formed of a stack of spaced apart coalescing plate each having orthogonally arranged corrugations running both laterally and longitudinally, a pair of bottom supports each having an undulating upper edge conforming to the lateral corrugations of the coalescing plates, the bottom supports being spaced apart from each other for supporting the coalescing plates, a pair of top supports each having an undulating bottom edge conforming to the lateral configurations of the coalescing plates and positioned directly over and in common vertical planes with the bottom supports and elongated, preferably fiberglass rods extending through the coalescing plates and attached at the ends thereof to the bottom and top supports holding the supports and coalescing p
