Patent number: 8052235Abstract: A storage compartment comprises an external enclosure having an opening and a holding compartment that is capable of being inserted into and withdrawn from the interior of the external enclosure through the opening in the external enclosure. Stored articles are contained within the holding compartment. The external enclosure and the holding compartment have coacting surfaces, and a seal is interposed between those coacting surfaces for sealing off the interior of the holding compartment to the entry of gases when the holding compartment is inserted into the external enclosure and the coacting surfaces of the external enclosure and the holding compartment are brought together in a sealing relationship with the seal. Complementary surfaces at the holding compartment and at the exterior of the external enclosure are in engagement with one another and provide surfaces along which the holding compartment travels when it is inserted into and withdrawn from the interior of the external enclosure.Type: GrantFiled: June 6, 2007Date of Patent: November 8, 2011Assignee: Electrolux Home Products, Inc.Inventors: Paul H. Kelly, Aaron W. Arvia, Edmund Scott Richardson, Kenneth L. Pope, Richard B. Moulder, David A. Simoni

Patent number: 6899149Abstract: A dispensing system for dispensing volatile liquids such as hydrocarbon fuel for vehicles into a tank having a filler neck also collects the vapors to reduce atmospheric pollution. A fuel delivery hose includes a hand-held fuel valve and nozzle for insertion in the opening of the tank. A means delivers fuel under pressure to the fuel delivery hose, and another means provides electrical pulses corresponding to the volumetric flow of liquid through the fuel delivery hose when the fuel valve is open. A vapor recovery hose includes a vapor intake connected to the hand-held nozzle for insertion in the opening of the tank without sealing with the tank, and a motor driven vapor pump produces a volumetric flow through the vapor recovery hose corresponding to a signal applied to the motor. A processing means produces the signal applied to the motor in response to the electrical pulses to produce a volumetric flow of vapor slightly greater than the volumetric flow of fuel to the tank.Type: GrantFiled: March 15, 1993Date of Patent: May 31, 2005Assignee: Gilbarco Inc.Inventors: Hal C. Hartsell, Jr., Kenneth L. Pope

Patent number: 6532999Abstract: A pressure sensor includes a pair of inputs for determining the pressure within a vapor recovery path. The inputs are positioned about a flow restrictor within the vapor recovery path. The vapor recovery path may include a mounting platform for attaching the pressure sensor and positioning the inputs relative to the flow restrictor. In one embodiment, a vapor sensor may also be positioned within the vapor recovery path. An inlet port and an outlet port direct vapor from the vapor recovery path to a sensor. The inlet and outlet ports are positioned relative to the flow restrictor for forcing the vapor through the sensor. In this embodiment, a common flow restrictor within the vapor recovery path may accommodate both the vapor sensor and the pressure sensor. If vapor is not being returned in the vapor return path properly, the fuel dispenser may set an alarm condition and/or shut down the fuel dispenser operation.Type: GrantFiled: December 11, 2001Date of Patent: March 18, 2003Assignee: Gilbarco Inc.Inventors: Kenneth L.

Patent number: 6357493Abstract: A system and method for determining whether a vehicle is equipped with an ORVR system. A processor receives a signal from a fuel pump or the like indicating the fuel being dispensed by the fuel dispenser. The processor is programmed to determine a threshold vapor concentration level based on the signal. Processor further receives a signal from at least one environmental sensor indicating at least one environmental condition to which the fueling operation is exposed. The processor is further programmed to adjust the threshold vapor concentration either up or down dependent upon the environmental condition. Finally, processor receives an actual vapor concentration from a vapor sensor. The processor then compares the actual vapor concentration value with the adjusted threshold vapor concentration value to determine whether the vehicle is equipped with an ORVR system.Type: GrantFiled: October 23, 2000Date of Patent: March 19, 2002Assignee: Marconi Commerce Systems Inc.Inventors: William P.

Patent number: 5464466Abstract: An apparatus and method for maintaining a desired pressure within a fuel storage tank or tanks while minimizing or eliminating the amount of pollutants discharged from the fuel storage tank(s). A fuel storage tank is provided with a conduit and a chamber interfaced along the path of the conduit such that all fluid passing through the conduit must pass through the chamber. A fractionating membrane is housed within the chamber for capturing pollutants while allowing air to pass through. As pollutants are collected on the fractionating membrane, they permeate, thereby reducing the pressure in the tank and associated conduit. A vapor pump is provided for drawing vapor through the conduit and the membrane, and for drawing pollutants off of the membrane. A pressure transducer located in the tank or associated piping makes the vapor pump responsive to the pressure therein. A vent is further provided for allowing air into the tank and piping and for depressurizing the tank and piping.Type: GrantFiled: November 16, 1993Date of Patent: November 7, 1995Assignee: Gilbarco, Inc.Inventors: Seifollah S. Nanaji, Kenneth L. Pope, Richard R. Sobota

Patent number: 5417256Abstract: A fuel dispensing system includes a main vapor recovery path and a vapor pump to provide a vacuum along the path. Dispensers for dispensing fuel from a storage tank each have a branch conduit having one end adapted to be coupled to a receiving tank, and another end opening into the main vapor path, to provide a branch vapor recovery path. A sensor provides a first electrical signal indicative of the flow of the fuel being delivered, and a vapor flow sensor in the branch conduit supplies a signal indicative of the actual vapor flow. An adjustable valve in the branch conduit has an opening that is adjustable responsive to the magnitude of a control signal to vary the impedance of the vapor recovery path.Type: GrantFiled: October 4, 1993Date of Patent: May 23, 1995Assignee: Gilbarco, Inc.Inventors: Hal C. Hartsell, Jr., Kenneth L. Pope

Patent number: 5269353Abstract: An apparatus for pumping recovered vapor in a vapor recovery liquid fuel dispenser includes a liquid fuel dispenser apparatus adapted to dispense liquid fuel to a liquid fuel dispenser nozzle proximate a fuel vapor passage. A transducer associated with the dispenser apparatus generates a liquid fuel flow signal indicative of the rate of liquid fuel flow therethrough. A vapor pump driven by an electric motor is arranged to pump vapor from the vapor passage through a vapor pump inlet to a vapor pump outlet and has a characteristic that the flow rate through the vapor pump at a given vapor pump operating speed is inversely proportional to the difference between the vapor pump inlet and outlet pressures. Sensors associated with the inlet and outlet ascertain inlet and outlet pressures and generate signals representative thereof. A controller for the vapor pump includes vapor recovery control electronics and motor drive electronics.Type: GrantFiled: October 29, 1992Date of Patent: December 14, 1993Assignee: Gilbarco, Inc.Inventors: Seifollah S.
