Abstract: An automated fueling assembly includes a refueling station that is positioned at a gas station for refueling gas burning vehicles. The refueling station includes a control panel that is movably integrated into the refueling station to facilitate a driver of a vehicle to access the control panel. The refueling station includes a robotic arm that is actuatable to extend into a refueling port in the vehicle for refueling the vehicle without requiring the driver to exit the vehicle. A pair of sensing units is each positioned on a driveway adjacent to the refueling station. Furthermore, the refueling station is turned on when each the sensing units senses the weight of the vehicle.

Abstract: The method for dispensing dosed amounts of a liquid contained in a storage reservoir connected to a dispensing duct provided with a nozzle for delivering the liquid into a receptacle associated with an indicator, delivering in the form of a signal representative of the value of the amount of liquid present in the receptacle and said duct distant from the nozzle, being associated with a closing mechanism which, by command, closes or releases the passage of the liquid through the duct, including the following steps: a) releasing the passage of the liquid between the reservoir and the nozzle by operating the closing mechanism, so that the liquid can fill the portion of the duct between the closing element and the dispensing nozzle; b) closing the passage of the liquid by operating the closing mechanism to interrupt the liquid flow; c) applying on the liquid column between the closing mechanism and the dispensing nozzle, at least a mechanical pulse of calibrated amplitude and/or intensity, for expelling from the

Abstract: A vapor recovery system nozzle capable of responding to the presence of an onboard vapor recovery system (ORVR) in an automobile. The invention includes a vapor recovery nozzle having a vapor passage in its nozzle spout and a vapor inlet in communication with the vapor passage. The spout includes a moveable seal mounted on the spout with the seal having a first position adjacent to the plurality of vapor inlets and a second position covering the vapor inlets so as to substantially block the passage of vapors through the vapor inlets. The seal may be biased in the second position.

Abstract: A safety tank apparatus is provided for installation to receive and store a liquid hydrocarbon or hydrocarbons, or the like, and from which the liquid may be withdrawn. It comprises tank structure including an inner metallic tank; an outer metallic tank protectively receiving the inner tank with accessible interior space laterally of the inner tank; a barrier wall between that interior space and the inner wall; an opening in the outer tank sidewall adjacent that interior space; and a closure closing the opening, the closure movable to expose the interior space to access from the exterior; and tank liquid flow control structure accessible through the side wall opening, for controlling filling of the liquid into the inner tank from the exterior of the safety apparatus, and for controlling liquid removal from the inner tank.

Abstract: The present invention relates to a vapor recovery nozzle with a turbine located in the nozzle. The turbine is driven by the flow of fuel. The turbine rotates an impeller located in the nozzle which draws away the vapor during pumping operations. The nozzle further has a hydraulic system for automatically shutting off the nozzle when fluid is displaced in an accumulator cylinder.

Abstract: A liquid spillage control apparatus is disclosed having a liquid holding chamber divided by a partition into a liquid transfer portion and a liquid retaining portion. A liquid spill transfer pipe connects the fuel holding chamber with a liquid tank. Overflow liquid passe through the liquid spill transfer pipe and the liquid transfer portion, over the partition and into the liquid retaining portion of the liquid holding chamber. An opening in the liquid holding chamber is connected by a line to an opening in a liquid fill nozzle. Liquid in the liquid holding chamber of a predetermined amount passes from the liquid holding chamber, through the line, and into the liquid fill nozzle to actuate the liquid sensor of the automatic liquid shut-off mechanism of the nozzle in order to terminate liquid flow from the nozzle into the liquid tank.

It comprises tank structure including an inner metallic tank; an outer metallic tank protectively receiving the inner tank with accessible interior space laterally of the inner tank; a barrier wall between that interior space and the inner wall: an opening in the outer tank sidewall adjacent that interior space; and a closure closing the opening, the closure movable to expose the interior space to access from the exterior; and tank liquid flow control structure accessible through the side wall opening, for controlling filling of the liquid into the inner tank from the exterior of the safety apparatus, and for controlling liquid removal from the inner tank.

Abstract: A safety apparatus for installation to receive and store a liquid hydrocarbon or hydrocarbons, or the like, and from which the liquid may be withdrawn comprising a structure including first and second inner metallic tanks, and an outer metallic housing protectively receiving the inner tanks, the outer housing having a side wall, there being upper interior space above the inner tanks and within the housing the second inner tank located within the first inner tank; the housing including a cover extending over the inner tanks; an opening in the sidewall, and a closure closing the opening, the closure movable to expose the upper interior space to access from the exterior; and control structure below the cover, and accessible through the opening for controlling flow of the liquid into the second tank from the exterior of the safety apparatus.

Abstract: An adapter for a gasoline pump nozzle which is equipped with a gasoline fume return hose that extends over the rigid tubular portion of the nozzle. The hose has an outer open end which is normally aligned with the other open end of the rigid tube. The hose is resiliently compressible so that the outer end of the hose can be moved relative to the tube beyond a protuberance on the tube which is located between the outer end of the tube and the housing of the nozzle. The housing contains a valve in a trigger mechanism and a control mechanism which prevents the valve from being opened by the trigger mechanism when the hose is in its extended state but is effective to enable the valve to be opened by the trigger mechanism when the hose is compressed. The adapter has a handle in a main body portion which contains a slot in an outer opening to the slot.

Abstract: A flow rate limiting device (40) for a fuel dispensing nozzle (10) having an inlet (12) through which fuel is supplied to said nozzle (10) from a supply hose (14) and an outlet (20) from which fuel is discharged, as into a tank of a vehicle. The device (40) includes a flow restrictor (42) which is mounted in the fuel dispensing nozzle in its internal flow passage (16) the flow restricter (42) is automatically operated to reduce the flow rate, when the flow rate of fuel through said nozzle (10) reaches a preselected threshold rate such as the rate established by governmental regulations. After the flow rate of the fuel in the internal flow passage (16) is reduced below the preselected threshold rate, the flow restriction is attentuated such that the flow in the passage (16) can increase and approach the threshold rate.

Abstract: An automatic shut-off fuel dispensing nozzle (10) with a flow rate limiting mechanism (90). The nozzle (10) includes a valve (24) which controls the flow of fuel through a passage (16) leading from the nozzle inlet (12) to the nozzle outlet (20) which is normally connected to a spout. This valve (24) is responsive to a manually operable lever and to a vacuum operated release mechanism (26) which automatically shuts the flow of fuel through the nozzle off when the level of fuel in a tank reaches a preselected level or when the flow of fuel through the nozzle reaches a preselected threshold rate of flow.
