Abstract: A hose end regulator for regulating pressure in fluid includes a main body having a fluid inlet and fluid outlet. A poppet moves between an open position to permit fluid to flow through the fluid outlet and a closed position to militate against fluid flowing through the fluid outlet. A primary spring permits the poppet to move between the open position and the closed position. A flow maximizer minimizes movement of the primary spring until a predetermined fluid pressure is reached within the main outer body.

Abstract: A nozzle adapter for coupling a fueling nozzle to an underwing type servicing adapter having a radially outward extending tab and a notch formed in an open end thereof comprises an outer body including a neck portion having a first conduit formed therein and a substantially cylindrical cap portion, the cap portion including at least one slot formed therein. An inner body has a second conduit formed therein and is disposed within the cap portion of the outer body and an annular channel is formed between the cap portion and the inner body. The at least one tab is received in the at least one slot and a rotation of the nozzle adapter relative to the servicing adapter causes a first aperture configured to receive a locking device therein to be aligned with the at least one notch of the servicing adapter.

Abstract: A differential pressure gauge for measuring a difference in pressure present between a low pressure portion of a fluid and a high pressure portion of the fluid includes a cylinder and a housing. The cylinder includes an opening. The housing includes an opening. A piston extends from a first end having a visual indicator to a second end having a remote indicator. The first end of the piston is in fluid communication with the high pressure portion of the fluid and the second end of the piston is in fluid communication with the low pressure portion of the fluid. A sensor is configured to sense a presence of the remote indicator when the remote indicator is within a sensing range of the sensor. The sensor is coupled to a sensor positioning mechanism for adjusting a position of the sensor with respect to the axial direction of the housing.

Abstract: A kit and method for manufacturing a reference standard for a water detection unit includes a substrate and a tray configured to receive the substrate therein. A tank is configured to receive at least one of the trays therein, wherein a fluorescent solution comprising water and uranine is provided to the tank via an inlet. The solution rises within the tank to saturate the substrate. The trays are then placed in a rotatable rack wherein the substrates are dried to remove excess solution. The dried substrates are then hermetically sealed within a transparent envelope.

Abstract: A sensor assembly including a flexible member having a first end and a second end, a rotating member connected to the second end of the flexible member, a positional element disposed on the rotating member, and a sensor capable of sensing a movement of the positional element. A movement of the second end of the flexible member allows the rotating member and the positional element to rotate.

Abstract: A closed loop system for obtaining a sample of a fluid from a source of fluid is disclosed, the system including a collection vessel having a fluid chamber disposed therein. A valve assembly is disposed within the collection vessel and adapted to selectively open and close a fluid communication path between the fluid chamber and an associated fluid receptacle. An inlet provides a fluid communication path between the source of fluid and the fluid chamber, and an outlet provides a fluid communication path between the fluid chamber and a fluid recovery system.

Abstract: A valve system for monitoring and controlling a flow of a fluid additive into a main fluid line is disclosed. The system includes a pump that provides a constant flow of the additive from a fluid reservoir through a supply conduit into the main fluid line. A portion of the fluid additive may be diverted into one or more return conduits leading back to the reservoir by opening a solenoid actuated valve in the return conduit. Flow meters are employed to detect the flow rates of the fluids in the supply conduit and the main fluid line. The flow meters provide signals to a control system, which are effective to control the operation of the solenoid actuated valves to maintain a desired flow of the additive into the main fluid line.

Abstract: A gauge for measuring the wear of selected cooperating surfaces of an adapter is disclosed. The gauge includes a plurality of rollers adapted to contact the selected cooperating surfaces of the adapter. A trigger mechanism is provided to cooperate with the rollers to indicate if the adapter is out of tolerance in respect of given dimensional targets.

Abstract: A water detector probe is disclosed which can be wetted with a small quantity of water and including a manually operated screw-type pump to force the water into an electrically conductive central passageway and thence into contact with the fuel side and, as well as, the grounded main body of the probe to complete an electrical circuit which, in turn, controls fuel flow to an aircraft, for example.

Abstract: A wear gauge for determining excessive wear of the notches and lugs of an aircraft fueling nozzle adapter to expeditiously sense wear which might result in leakage of fuel during an aircraft refueling operation.

Abstract: A test gauge for testing an aircraft fueling nozzle for excessive wear in the interlock mechanism including a slotted fixture designed to depress the interlock plate to simulate more advanced wear on the interlock mechanism of the nozzle than is actually present in order to provide an advanced warning of excessive wear.

Abstract: A syringe and adapter combination allowing the syringe to be filled with fluid by the employment of one hand of an operator.

Abstract: A pressure gauge having a pressure operated piston for measuring the difference in pressure between two pressure signals including an automatically operative pressure relief valve and a manually operable three-way valve to provide a venting function useful for inspecting the operation of the pressure operated piston of the pressure gauge.
