20090145490 | Water conservation / hot water recirculation system utilizing timer and demand method - In most homes today, when a person turns on a hot water faucet, he or she must wait for residual cold water to flow out of the hot water pipe as hot water travels from the water heater to the faucet. That residual cold water typically goes down the drain. In some buildings, recirculating hot water systems keep hot water flowing in a loop, thereby making hot water immediately available and eliminating the waste of residual hot water, but these systems waste energy from thermal radiation in the hot water pipes at times when no hot water is being utilized. The invention conserves both water and energy by controlling the recirculation of residual cold water by means of momentary activation of any hot water faucet, and also by programmed time-of-day intervals, whereupon the pump replaces the residual cold water with hot water and recirculates the residual cold water, and then turns off so as to avoid energy waste from running hot water through the loop at times it is not needed. The invention provides for fast installation of the pump, detector, and controller on the hot water outlet side of the water heater. It can be used in buildings that have separate hot water return pipes, and it can also be used in configurations where existing cold water pipes are used for the return of hot water. | 2009-06-11 |

20090145517 | PROTECTIVE DEVICES FOR AIRCRAFT FUEL FILLER PORTS - Protective devices are provided subjacent to the filler port within an aircraft's wing fuel tank so as to protect the lower wing skin from being struck by a nozzle associated with refueling equipment. In this regard, when inserted into the filler port, the nozzle is brought into contact with the protective device which serves to deflect the nozzle in laterally (e.g., in an inboard direction to thereby prevent the nozzle from striking the lower wing skin. Thus, when initially inserted into the filler port in a generally perpendicular orientation relative to a horizontal plane, the terminal end of the nozzle will contact with the arcuately concave inner surface of the device. Since the protective device's surface slopes downwardly and laterally in an inboard direction, continued insertion of the nozzle into the filler port will cause the nozzle to assume an angularly canted condition in an inboard direction (i.e., a direction toward the aircraft's fuselage). Thus, even if the full length of the nozzle is inserted into the filler port, the angularly canted orientation of the nozzle in an inboard direction caused by the protective device will prevent the nozzle's terminal end from striking and thereby potentially damaging the lower wing skin. | 2009-06-11 |
