Abstract: A system for delivering natural gas, from a moveable transport or pipeline, is off-loaded at an automotive re-fueling station, or other end-user facility, into one or more storage vessels equipped with internal flexible bladders. The pressure of the gas, stored inside the bladders, will be increased to levels sufficient for re-filling automotive on-board storage tanks, or other end uses, by pumping a hydraulic fluid in the annulus between the bladder and the walls of the steel storage vessels, thereby collapsing the flexible bladder and squeezing gas out to an on-board storage tank. The use of a hydraulic pump, instead of a more-expensive compressor, to pressurize the gas, results in significant cost savings which reduces the overall cost of CNG at the station, making CNG (the "preferred alternative fuel") less expensive than gasoline and/or diesel, which will enable CNG to replace gasoline and/or diesel as the primary fuel for automobiles, trucks, and busses.

Abstract: A system for delivering natural gas, from a pipeline, is loaded onto a movable transport by flowing the gas into multiple pressure vessels equipped with internal flexible bladders which will contain the gas until the pressure in the vessels equalize with the pressure in the pipeline. At that time, the transport will be moved to a compressed natural gas (CNG) re-fueling station. At the re-fueling station, the multiple pressure vessels will be connected to an un-loading conduit leading to the storage facilities. The natural gas will be un-loaded by pressure differential until pressures equalize, then pressurized hydraulic fluid will be pumped into the annulus between the bladder and the steel walls of the pressure vessel which will deflate the bladder and squeeze the remaining gas out of the bladder to storage. The transport is then disconnected from the un-loading facilities and returned to the pipeline for re-filling with natural gas.

Abstract: A fuel tank switching apparatus provides for the automatic switching of fuel delivery systems from a tank or tanks containing fuel which is taxed, to an auxiliary tank which stores untaxed fuel therein. The apparatus is particularly adapted for use in large, over the road diesel powered semi trucks, but may be adapted to other types of motor vehicles as well. The apparatus automatically transfers fuel delivery and return to the auxiliary fuel tank whenever the parking brake is applied, which action will only occur when the truck or vehicle is parked, or possibly in very rare emergency situations. As both the parking brake annunciator (light or audible device) and the pneumatic pressure system are independent of the primary service brake system in large vehicles, the apparatus receives a signal from the parking brake system to switch tanks automatically with no intervention required or allowed by the driver or operator.
