Abstract: A fluorescent dye in combination with an aviation functional fluid. The fluorescent dye is present in the functional fluid from about 0.0001% by weight to about 1% by weight. A method of detecting a leak in an aviation mechanical system that includes a functional fluid with a fluorescent dye. The method would include irradiating select areas of an airplane with a select spectrum of light, and observing an emission from the fluorescent dye.

Abstract: A multi-profile adapter assembly is disclosed for connecting a pressurized fluid source to two or more different fittings. The adapter assembly includes an injector connector removably attachable to a hose connected to a pressurized fluid source and including an internal conduit for channeling a flow of pressurized fluid. An inner housing is connected to the injector connector and includes a channel leading to a second opening and a cavity configured to receive an access fitting on an AC system. A one way valve controls flow from the conduit in the injector connector into the inner housing. An adapter is connected to the inner housing and includes a first contour configured to engage with a first fitting and a second contour configured to engage with a second fitting. The inner housing and adapter are movable relative to one another for changing the location of the first contour and second contour.

Abstract: The present invention provides a white-fluorescing dye blend comprising at least one neutral blending oil, a perylene-based compound, naphthalimide-based compound, and a coumarin-based compound. This white-fluorescing dye blend has a substantial fluorescent response to illumination by the entire range of commonly available inspection lamps. The resultant blended dye is an all-purpose blend that is satisfactory for all automotive fluids and all inspection lamps.

Abstract: A recovery and recharge apparatus and method for delivering a dose of fluorescent dye to an air conditioning/HVAC system. A supply line provides for both recovering and recharging of refrigerant into the system. The supply line includes a first segment connected to the recovery and recharge unit and having a single internal conduit for channeling reclaimed refrigerant into the recovery and recharge unit and for channeling refrigerant from the reservoir. A dye compartment is fluidly connected to the first segment and includes an interior cavity with an access panel for permitting access to the cavity for receiving a fluorescent dye material. A second segment is fluidly connected to the dye compartment and has an outlet port for connecting to a low side connection on the air conditioning/HVAC system. Preferably one way valves are located on opposite sides of the dye compartment and allow recovered refrigerant to bypass the dye compartment.

Abstract: An ultrasonic detector has a housing containing a transducer, a battery or other power supply, and any other necessary electronics. At a front end of the housing is a socket into which one of a plurality of interchangeable probes can be inserted. At the rear end of the housing, there is a handle by which an operative can hold the detector in use. On the inside of the housing, extending at least partially into the handle, is an elongate chamber within which at least one probe can be stored. A cover of the handle closes a rear end of the probe storage chamber and can be removed to expose a portion of the probe storage chamber and allow a probe to be inserted or removed.

Abstract: A process for applying a fluorescent leak detection dye to a component of an air conditioning system. The process involves the steps of (i) providing a fluorescent dye that is solid at room temperature, (ii) exposing the dye to an elevated temperature to melt the dye into a liquid or flowable state, (iii) injecting, channeling, spraying or placing the flowable dye into or on a component or an HVAC or A/C system, (iv) allowing the dye to resolidify in or on the component, (v) attaching the component to the HVAC or A/C system, and (iv) dissolving the resolidified dye in a liquid/gas.
