Abstract

An apparatus for providing fuel comprises a fuel handling portion and an air handling portion. The fuel handling portion comprises a fuel tank adapted to store fuel as well as a fuel nozzle in fluid communication with the fuel tank and adapted to dispense fuel from the fuel tank. The air handling portion comprises an air tank adapted to be filled with pressurized gas from a pressurized gas source. After the pressurized gas source is removed, the air handling portion is operative to apply the pressurized gas from the air tank to the fuel in the fuel tank so as to provide a motive force for dispensing fuel through the fuel nozzle.

Claims

exact text as granted — not AI-modified
1 . An apparatus for providing fuel, the apparatus comprising:
 a fuel handling portion, the fuel handling portion comprising a fuel tank adapted to store fuel, and a fuel nozzle in fluid communication with the fuel tank and adapted to dispense fuel from the fuel tank; and   an air handling portion, the air handling portion comprising an air tank adapted to be filled with pressurized gas from a pressurized gas source and the air handling portion operative to, after the pressurized gas source is removed, apply the pressurized gas from the air tank to the fuel in the fuel tank so as to provide a motive force for dispensing fuel through the fuel nozzle.   
     
     
         2 . The apparatus of  claim 1 , wherein the fuel handling portion comprises a fuel filter. 
     
     
         3 . The apparatus of  claim 1 , wherein the air handling portion comprises a pressure regulator operative to modify a pressure of the pressurized gas from the air tank before it is applied to the fuel in the fuel tank. 
     
     
         4 . The apparatus of  claim 1 , wherein the air handling portion comprises an air filter operative to filter the pressurized gas from the air tank before it is applied to the fuel in the fuel tank. 
     
     
         5 . The apparatus of  claim 1 , further comprising an electronic controller. 
     
     
         6 . The apparatus of  claim 5 , wherein the electronic controller is in signal communication with a detector that allows the electronic controller to determine a composition of fluid received from the fuel tank. 
     
     
         7 . The apparatus of  claim 6 , wherein the determination is based at least in part on an electrical conductivity of the fluid. 
     
     
         8 . The apparatus of  claim 5 , wherein the electronic controller is operative to control one or more pumps. 
     
     
         9 . The apparatus of  claim 5 , wherein the electronic controller is operative to control one or more motorized selector valves. 
     
     
         10 . The apparatus of  claim 5 , wherein the electronic controller is operative to cause fluids from the fuel tank to be returned back to the fuel tank. 
     
     
         11 . The apparatus of  claim 5 , wherein the electronic controller is operative to cause fluids from the fuel tank to be delivered to a waste container. 
     
     
         12 . The apparatus of  claim 5 , wherein the electronic controller is operative to cause water from a water source to be introduced into the fuel tank. 
     
     
         13 . The apparatus of  claim 1 , wherein the apparatus is at least partially implemented in the form of a rolling cart. 
     
     
         14 . A method of providing fuel, the method comprising the steps of:
 filling a fuel tank with fuel, the fuel tank in fluid communication with a fuel nozzle;   pressurizing an air tank with a gas from a pressurized gas source;   removing the pressurized gas source; and   dispensing the fuel from the fuel tank through the fuel nozzle while allowing pressurized gas from the air tank to provide a motive force for dispensing the fuel.   
     
     
         15 . The method of  claim 14 , further comprising the step of introducing water into the fuel. 
     
     
         16 . The method of  claim 14 , further comprising the steps of introducing water into the fuel tank a plurality of separate times. 
     
     
         17 . The method of  claim 14 , further comprising the step of mixing the contents of the fuel tank. 
     
     
         18 . The method of  claim 14 , further comprising the step of waiting a predetermined time for the contents of the fuel tank to settle without mixing the fluid in the fuel tank. 
     
     
         19 . The method of  claim 14 , further comprising the step of determining a composition of fluid received from the fuel tank. 
     
     
         20 . The method of  claim 14 , further comprising the step of pumping fluid from the bottom of the fuel tank and sending the fluid to a waste container.
