  • Patent number: 10371105
    Abstract: A fuel treatment module treats fuel with infrared radiation from a plurality of infrared radiation emitting elements arranged in a structure configured to ensure sufficient exposure of the fuel to infrared radiation. Such structure includes a head cap and spacer having through bores providing a manifold through which fuel flows into multiple IR/shunt columns of infrared radiation emitting elements that are disposed within a canister. Then the fuel moves out of the multiple IR/shunt columns into the open area of the canister where the fuel then flows around the exterior of the columns, exposing the fuel to further infrared radiation treatment.

  • Patent number: 9246261
    Abstract: An underwater rolling seal connector assembly has releasably mateable connector units with one or more rolling seals mounted in front faces of units. The rolling seals are rotatable back and forth between a closed position sealing one or more chambers within the respective units which contain one or more contacts and an open position in which bores through the seals are open to allow contacts in one unit to pass through the seal openings and engage contact in the other unit. A shell of one connector unit has inwardly facing cam formations and each rolling seal has outwardly directed eccentric rotators configured for engagement with respective cam formations on mating and de-mating of the connector units, whereby travel of the respective rotators along the respective cam formations during mating and de-mating rotates the rolling seals into the open and closed positions, respectively.

  • Patent number: 8128444
    Abstract: An emergency floatation system for an aircraft includes an actuator box assembly that activates the floatation system either electrically or manually. The actuator box assembly is separated from a valve assembly of an inflation reservoir and provides an interface between an electromechanical trigger system and a redundant mechanical trigger system. The actuator box includes a pivot member that provides an interface for the redundant trigger systems and an output actuator. For normal operation a button in the cockpit is pressed which sends an electrical signal to an electromechanical actuator in the actuator box assembly. The electromechanical actuator rotates the pivot member, which operates the output actuator and opens the valve assembly. Alternatively, should the electrical system of the aircraft fail, the pilot or other occupant may activate the mechanical trigger system, thereby rotating the pivot member and activating the output actuator to open the valve assembly.

    Abstract: A variable volume raft containing adjustable ratio and amounts of air and or water. The buoyancy and ballast of the raft are routinely adjusted to accommodate additional occupants and changing weather conditions. A manual pump can be the primary or back up source for initial inflation. The torque pump twisted by hand or amplified by a lever arm generates air pressure for maintenance and repairing deflating lacerations at sea. The pumps collector gathers and pressurizes rain water for drinking in one chamber while pressurizing sea water as a stabilizing ballast in another chamber. A double hull or full floor chamber allows huge variations in buoyancy or ballast as dictated by changing needs for stability versus mobility. A compressed liquid or two-part foam confers puncture resistance to a portion of the raft. A thrown self-righting manual air horn, worn water-activated air horns and water activated transmitted signals, mark the site for rescuers.
