Abstract: A non-metallic fluid coupling is disclosed with electrical current transferring elements incorporated therein. The coupling is formed of two C-shaped halves of non-metal, non-conducting material, where each halve includes integral hinges and latches, or hinges and latches made of a common material with the C-shaped halves. A non-metallic, substantially rigid sealing sleeve can be incorporated into the coupling to seal the coupling while maintaining the strength of the coupling.

Abstract: A closure indicator for a fluid coupling is disclosed where the fluid coupling has first and second semi-circular members hinged together at a first end and latched together at the opposite end, the indicator comprising an upper surface including a stop on a rear surface for arresting rotational travel in a first direction, first and second sidewalls with elongate slots, a spring biasing the indicator in the first direction, and first and second arms extending from said first and second sidewalls, respectively, to a position under a pin of a bracket only when the members are latched together.

Abstract: An automatic fill system includes a tank, a transfer hose, and a valve assembly. The valve assembly has a first end having an outlet orifice configured to be received within the tank. The valve assembly also includes a second end configured to be connected in fluid communication with the transfer hose with the second end having an inlet orifice. The valve assembly also includes at least one fluid passageway between the inlet orifice and the outlet orifice, and a check valve coupled to a spring and a seal. The seal is configured to be slidably moveable within a piston chamber. The valve assembly further includes a heating element located within a heating element chamber and configured to heat the valve assembly. Finally, the valve assembly includes a jet level sensor with a sensor inlet and a sensor outlet. The jet level sensor is in fluid communication with the piston chamber.

Abstract: A process of forming a cushioned clamp in accordance with aspects of the present disclosure includes configuring a single-ply of woven fiberglass into a longitudinal tube to form a single-ply fiberglass sleeving, coating the single-ply fiberglass sleeving with an aluminum paint, subjecting the coated single-ply fiberglass sleeving to a warming medium, while pliable due to the warming medium, cutting the sleeving into discreet, individual pieces configured for forming a sleeve, folding a first cut end in on itself and pulling the first cut end toward a center of the sleeve to form a first rolled end, and folding a second cut end in on itself and pulling the second cut end toward a center of the sleeve to form a second rolled end, and slidably mounting the sleeve onto a bare metal clamp to form the cushioned clamp.

Abstract: A system and method of disinfecting and sanitizing potable water on an aircraft. An ozone generator generates a supply of ozone which is fed into an injector. A pump is connected to a water supply line and an end of an injector. Water flows from the water supply line through the pump and into the injector where the water and the supply of ozone mix to disinfect the water.

Abstract: A clamping method and apparatus including two halves of a clamp mated at a first end. The two halves are pivotally connected at a second end. The present invention is configured to permit the device to be repeatedly used without extended wear.

Abstract: A shut off valve (10) is provided for use in an aircraft lavatory system (70) during maintenance sanitizing operations. The shut off valve includes an inlet passage (20) in intermittent fluid communication with an outlet passage (30) and a magnetic flapper body (40) movable between a rest position and a seal position between said inlet passage and said outlet passage. The flapper body is moved by a magnetic actuator (60) whereby upon placing said magnetic actuator within the proximity of the flapper body, the flapper body is moved form the rest position and, with the assistance of fluid flow within the valve, into the seal position, thus preventing fluid communication between the inlet passage and the outlet passage.

Abstract: A heater for heating a rigid fluid line or hose for freeze protection. The heater has a base made of an outer base layer, a middle base layer attached to the outer base layer; and an inner base layer attached to the middle base layer. The inner base layer can be uncured silicone (before assembly processing). A resistance wire is wound around an electrically non-conductive core and located on the inner base layer. The resistance wire can be a high gauge wire providing for a small moment of flexure. A cover includes an inner cover layer covering said resistance wire. This inner cover layer can be uncured silicone (before assembly processing). A middle cover layer is attached to the inner cover layer, and an outer cover layer is attached to the inner cover layer. The outer cover layer protects the heater from abrasion.

Abstract: A coupling assembly for fuel transfer includes a first inner conduit attached to a first ferrule adapter and a second inner conduit attached to a second ferrule adapter. An inner conduit coupling engages the first inner conduit sealing mechanism and the second inner conduit sealing mechanism, thereby connecting the first inner conduit to the second inner conduit. A first outer conduit surrounds the first inner conduit. The first outer conduit is attached to the first ferrule adapter and the second outer conduit is attached to the second ferrule adapter. An outer conduit coupling engages the first and second outer conduit sealing mechanism thereby connecting the first outer conduit to the second outer conduit.

Abstract: Reciprocating or push-pull control cable assemblies have fittings permanently attached, preferable by swaging or other mechanical deformation process, to the ends of a control cable or core that reciprocates within an outer casing. The fittings have a projected width no greater than the inner diameter of the casing. As a result, the entire control cable, with fittings attached, can be pulled through the casing to remove the control cable for inspection, maintenance or replacement. The cable also have a unique combination of ball joint assemblies and excluder seals that effectively exclude contaminants from the interior of the casing.

Abstract: Apparatus for conducting fluid and preventing its icing have a fluid line structure and a tubular fluid line element located in that fluid line structure and having a cross-section sufficient for a desired throughput of fluid. A heater element is located inside the fluid line structure and is in heat-transfer relationship with an inside of the tubular fluid line element. Such heater element may be an electric heater element inside the fluid line structure encompassing the tubular fluid line element in heat-transfer relationship with an inside of that tubular fluid line element. A frangible or other fluid line nipple may be removably connected to the fluid line structure, and the tubular fluid line element may extend from that fluid line structure to that fluid line nipple. A heat transfer reduction may be provided between the electric heater element and the fluid line structure outside of the tubular fluid line element.

Abstract: Fuel lines aboard aircraft are safeguarded against buildup of electric charges. A series of metallic tubes each having opposite open metallic tube ends are prepared for such fuel lines. External metallic ferrules are prepared for the opposite metallic tube ends of these metallic tubes. Each of these metallic ferrules is equipped with an electric discharge terminal for electric charges. Each metallic ferrule is bonded externally to a metallic tube end so that each metallic ferrule and a margin of that metallic tube end extend in one piece circumferentially around an inside of that metallic tube end and axially in one piece for an axial width of that metallic ferrule. External electric conductors extend between electric discharge terminals of adjacent metallic ferrules along the fuel line.
