Abstract: A reconnectable frangible coupling wherein at least one coupling part includes an operating valve and a safety valve. The operating valve utilizes the relative axial movement of the coupling parts during coupling and uncoupling to open and close, respectively, and the spring biased safety valve is engaged and retained in an open position by a valve retainer interposed between the valves. Frangible portions maintain the valve retainer in engagement with the safety valve and upon the coupling being subjected to severe impact, such as an aircraft crash, the frangible portions fracture permitting the valve retainer to disengage from the safety valve allowing the safety valve to close.

Abstract: A system for repairing pipeline, such as underground fuel, gas or water pipeline systems which have been damaged by explosives, wherein the ruptured sections have been misaligned. Quick-connect fittings are attached to the misaligned pipe ends after trimming and a bridging conduit system is interposed between the fittings having adjustable portions for accommodating the misalignment. Rotative angular sections provide universal adjustment while retaining the fluid-tight integrity of the apparatus.

Abstract: A fitting for rigid conduit including an annular body receiving the conduit and including a seal assembly utilizing an elastomeric seal axially compressed and radially expanded to engage the conduit by a compression ring. A ring retainer maintains the seal assembly in a preliminary position during shipping and assembly of the coupling with the conduit, and the ring retainer includes a second position retaining the seal in a sealed expanded condition. The fitting also includes a conduit positioning abutment capable of accommodating conduit displacement during sealing.

Abstract: The invention pertains to a crashworthy valved fitting for interconnecting a tank, such as a fuel tank, with a fluid line wherein valve structure is manually operated, and fluid pressure assists in maintaining the valve in a closed condition. An extension defined upon a Tee fitting body, which may be separated therefrom at a frangible location, is circumscribed by a mounting surface and extends into a tank opening, and the extension side wall includes a plurality of orifices whereby communication between the tank and the fitting is achieved. A displaceable valve selectively seals the extension orifices, and a manually displaceable valve actuator incorporates locking means for maintaining the valve in the open position, and permitting releasing of the valve of for movement to a closed position. Pressure faces defined upon the valve of differential areas subjected to the pressurized medium produces a force for assisting to maintain the valve in the closed condition.
