Patent number: 7225664Abstract: A pump housing that contains a pump that draws fuel from an underground storage tank containing fuel to deliver to fuel dispensers in a service station environment. The pump is coupled to a double-walled fuel pipe that carries the fuel from the pump to the fuel dispensers. The double-walled fuel piping contains an inner annular space that carries the fuel and an outer annular space that captures any leaked fuel from the inner annular space. The outer annular space is maintained through the fuel piping from the pump to the fuel dispensers so that the outer annular space can be pressurized by a pump to determine if a leak exists in the outer annular space or so that fuel leaked from the inner annular space can be captured by a leak containment chamber in the pump housing.Type: GrantFiled: July 18, 2005Date of Patent: June 5, 2007Assignee: Gilbarco Inc.Inventors: Ray J. Hutchinson, Donald D. Halla, Richard G. Dolson, Robert P. Hart, Richard K. Lucas, Kent D. Reid

Patent number: 7152004Abstract: A system and method for calculating the flow rate of a dispensing point or flow capacity of a pump and fuel delivery system and determining if the dispensing point or fuel delivery system has a blockage and/or a performance problem if the calculated dispensing point flow rate is other than expected. The calculated dispensing flow rate is calculated by collecting fuel tank level data points for a dispensing point that fall within start and stop events of the dispensing event. The slope of a fitted line to the fuel tank level data points is used as the indication of the flow rate of the dispensing point. Different mathematical techniques may be used to improve the flow rate calculation to compensate for the minimum resolution of collecting fuel tank level data and the dead time included in the data of a dispensing transaction.Type: GrantFiled: October 12, 2004Date of Patent: December 19, 2006Assignee: Veeder-Root CompanyInventors: Donald S. Reichler, Adriano Baglioni, Thomas C. Zalenski, Robert P. Hart, Richard K. Lucas

Patent number: 7076994Abstract: A submersible turbine pump includes a power head enclosed in a casing. A vacuum source associated with the submersible turbine pump draws a vacuum in the interior space of the casing. A pressure sensor may be used to monitor the vacuum in the interior space to detect a leak in the power head or the casing. If a leak is detected, an alarm may be generated and the submersible turbine pump may be deactivated.Type: GrantFiled: October 22, 2005Date of Patent: July 18, 2006Assignee: Gilbarco Inc.Inventors: Ray J.

Patent number: 6997042Abstract: A pump housing contains a pump that draws fuel from an underground storage tank to deliver fuel to fuel dispensers in a service station environment. The pump is coupled to a double-walled riser pipe that carries the fuel from the underground storage tank to the pump. The double-walled fuel piping contains an inner space that carries the fuel and an outer annular space that captures any leaked fuel from the inner space. The outer annular space is coupled to a vacuum created by the pump to determine if a leak exists in the outer annular space. An alternate submersible turbine pump has a double-walled housing with a pressure sensor disposed in the interstitial space of the double-walled housing. A vacuum may be created therein to determine if leaks are present in the housing of the submersible turbine pump.Type: GrantFiled: November 6, 2003Date of Patent: February 14, 2006Assignee: Gilbarco Inc.Inventors: Ray J.

Patent number: 6978661Abstract: A vacuum generator that is coupled to a double-walled fuel supply piping internal to a fuel dispenser that carries the fuel from the underground storage tank to the hose and nozzle of the fuel dispenser. The double-walled fuel supply piping contains an inner piping that carries the fuel. An interstitial space is formed by the space between the inner piping and an outer piping that surrounds the inner piping to capture any leaked fuel from the inner piping. The interstitial space is coupled to a vacuum created by the vacuum generator to determine if a leak exists in the interstitial space. The vacuum generator may be a standalone unit or may be a submersible turbine pump that also pumps fuel from the underground storage tank to the fuel dispenser.Type: GrantFiled: February 9, 2004Date of Patent: December 27, 2005Assignee: Gilbarco Inc.Inventors: Ray J.

Patent number: 6975964Abstract: Determining a maximum dispensing efficiency of a dispensing point in a fuel dispenser and determining if a dispensing point has a blockage and/or a performance problem if the maximum dispensing efficiency is less than expected. The maximum dispensing efficiency is calculated by determining the dispensing events exhibiting the lowest time for dispensed volume from a set of volume and time pair measurements for the dispensing point. The dispensing events exhibiting the lowest time for dispensed volume that are used to determine the maximum dispensing efficiency are taken from dispensing events where the amount of dead time, the time between the activation of a fuel dispensing event and the engaging of a nozzle and the time between the disengaging of the nozzle and the deactivation of the dispensing event, and customer or pre-pay transaction controlled reduced flow rates are minimized.Type: GrantFiled: October 11, 2003Date of Patent: December 13, 2005Assignee: Veeder-Root CompanyInventors: Donald S.

Patent number: 6968868Abstract: A method and apparatus for monitoring and determining fuel vapor recovery performance. The dispensing of liquid fuel into a tank by a gas pump nozzle displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow using a vapor flow sensor on a nozzle-by-nozzle basis. The determination of A/L ratios for individual nozzles are calculated using a reduced number of vapor flow sensors.Type: GrantFiled: December 11, 2003Date of Patent: November 29, 2005Assignee: Veeder-Root CompanyInventors: Robert P.
