  • Patent number: 11267334
    Abstract: A method for operating an evaporative emissions control system for use with a fuel tank that stores and delivers fuel to an internal combustion engine is provided. A vent shut-off assembly is provided that selectively opens and closes at least one valve to provide overpressure and vacuum relief for the fuel tank. The vent shut-off assembly selectively vents to a purge canister. The at least one valve is closed whereby vapor is precluded from passing from the fuel tank to the purge canister. A purge event is performed wherein dedicated fresh air is drawn into the purge canister and delivered from the purge canister to the engine.
    Type: Grant

  • Publication number: 20200055390
    Abstract: A pump assembly for a liquid trap of a vehicle fuel tank assembly includes a pump configured to couple to the liquid trap and selectively drain liquid therefrom, a sensor configured to monitor an inductive signature of the pump, and a controller programmed to operate the pump and monitor the inductive signature to determine if liquid is present in the liquid trap based on the monitored inductive signature.

  • Publication number: 20100013727
    Abstract: There is disclosed an LNB alignment device having a main body that removably attaches to a support arm of a satellite dish and has a plurality of mounting holes or rectangular sleeves configured to receive a plurality of low-noise block converters with feed horns (LNBs). The proximal and distal ends of the bar curve inwardly toward the satellite dish and curve slightly upward in a manner that the feed horns of LNBs outside of the focal axis are disposed higher and closer to the center of the reflector to improve signal quality.

  • Publication number: 20070169845
    Abstract: A filler tube assembly for use in a system having vapor recirculation includes a check valve having a flapper that is responsive to the viscosity of fluid around the flapper and/or a differential pressure across the flapper. The assembly also includes a nozzle chamber formed in the filler neck that has a constant diameter to ensure consistent vacuum generation regardless of fuel nozzle length.

  • Publication number: 20060235989
    Abstract: A vapor vent/tipping valve has a diaphragm with a bleed therethrough responsive to the differential pressure of bleed flow to control vapor venting to the canister and vapor recirculation to the filler tube. A dip tube causes rising fuel in the tank to close the dip tube and prevent vapor flow to the diaphragm bleed thereby starving the recirculation line and allowing nozzle discharge to create a vacuum in the filler and effect nozzle shutoff. Alternatively, float operated shutoff valves may be employed in the dip tube and vapor vent chamber inlet. the shutoff valves may include inertial members for closing the float valves to afford tipping/rollover protection.

  • Publication number: 20060074679
    Abstract: The invention relates to a system and method for purchasing a live performance recording. A live performance is recorded and edited. The live performance recording is compressed and tagged at a production means, and transferred to a kiosk soon after the performance ends. Consumers purchase a media storage device, the live performance recording, or both at the kiosk. The kiosk accepts consumer information to purchase the digital media at a later date and collate marketing information. Sales and marketing information is transmitted from the kiosk, through the production means, and stored in a central database. In a preferred embodiment, the kiosk operating system has the ability to recognize a wide variety of USB compatible external storage devices.
