Abstract: A method and apparatus for the recovery of vapors associated with propane fueling. The fuel vapor recovery system can be implemented with typical retail propane fueling facilities. The recovery method may include capturing vapors vented during the filling of a portable propane tank into a recovery tank, and transferring some of these recovered vapors into a second tank to be filled.

Abstract: Disclosed herein is a fuel injection apparatus for injecting fuel into a fuel cartridge. The fuel injection apparatus may include, for example, a container for fuel storage, a fuel supply pipe in fluid communication with the container, a first valve installed on the fuel supply pipe, a pump installed on the fuel supply pipe, a pressure gauge installed on the fuel supply pipe, and a bypass pipe fluidly connecting the container with the fuel supply pipe. A second valve may be installed on the bypass pipe. Methods for injecting fuel into a fuel cartridge are also disclosed herein.

Abstract: Freeze protection of an on-board emissions treatment substance storage and distribution system in a vehicle includes moving the emissions treatment substance away from a primary fuel/vapor area after filling of the emissions treatment system. In one embodiment an on-board emissions treatment system has a fill tube with a portion extending into a primary fuel fill tube to facilitate co-fueling of the primary fuel and emissions treatment substance. A pressure differential or vacuum is created in the emissions treatment fill tube after filling to move the emissions treatment substance away from a check valve disposed at the terminal end of the fill tube to prevent freezing of the check valve after filling. The emissions treatment substance may be moved out of the co-located portion of the fill tube to an area where passive or active heating of the fill tube may be applied to further reduce susceptibility to freezing.

Abstract: An apparatus and method for the recovery of propane vapors during propane cylinder refueling. The apparatus includes a separate recovery cylinder adapted to receive vapors that may be created during the refilling of propane cylinders. The recovered vapors may be used in the refilling of other cylinders during a subsequent refilling operation.

Abstract: A fitting is provided for attachment to an outlet of a fluid storage tank. The fitting divides the opening into two fluid pathways for independent use in filling and venting of the tank. The fitting prevents spillage and improves site safety at the tank location. The fitting comprises a manifold for attachment to the tank opening, and the manifold is divided into two internal pathways from the tank opening to the exterior environment. A stinger tube is attachable to one of the pathways and extends into the tank to deliver fluid. The stinger includes a siphon break for use in standardizing tank fill levels and in emptying fluid from the manifold to avoid site spillage of tank contents.

Abstract: Fluid flow valve assembly comprising a valve body having an external port and an inlet end having at least a first port, a second port, and a third port; a first valve disposed within the valve body and adapted to control fluid flow between the first and second ports; and a second valve disposed within the valve body and adapted to control fluid flow between the third port and the external port.

Abstract: A fuel storage and dispensing system reduces the emission of harmful volatile organic compounds. The system includes at least one storage tank, an air exhaust port, at least one fuel dispenser, a fuel dispensing nozzle, a rigid, fuel dispensing spout, a boot, a pressure relief chamber, a filter system, and at least one pump. The rigid, fuel dispensing spout further defines a non-coaxial fuel tube. The boot is configured to maintain a sufficient level of vacuum within the fuel storage and dispensing system. The boot is further configured to prevent fresh air from entering the fuel dispensing nozzle. The system may further include a pressure relief chamber that is effective in compensating for high temperature pressure build up in a vapor assist hose, a fuel dispensing nozzle and spout assembly, a vapor recovery boot assembly, and a Venturi shut-off assembly for a fuel dispensing nozzle and spout.

Abstract: A cylindrical housing 6 is secured to the bottom surface of an elevatable filling liquid tank 2, and a liquid injection pipe 16 is mounted on the bottom of the housing 6. An exhaust pipe 18 axially passes through the housing 6 and the liquid injection pipe 16, and is disposed for elevating movement. The exhaust pipe 18 is driven by an elevating mechanism 21. A holder 54 carrying a bottle mouth stuffing 52 is fitted in the housing 6, and is urged down by a spring 61. The bottle mouth stuffing 52 tightly engages the mouth of a vessel which is being raised as carried on a vessel receptacle, and accordingly its position is determined by the height of the vessel. The position of the liquid injection pipe 16 and the exhaust pipe 18 is modified in accordance with the elevation of the tank 2, independently from the bottle mouth stuffing 52. Accordingly, a void which remains in the top of the vessel after the vessel is filled with the liquid is adjusted only in accordance with the elevation of the tank 2.

Abstract: Metal particles are introduced to reactor beds in a hydrogen generator without introducing contaminating oxygen or nitrogen to the generator. The particles are protected against oxidation under an inert gas atmosphere, are flooded with water prior to injection into the generator, and are further flooded with hydrogen gas drawn from the generator to replace the water prior to injection. The generator includes a receiving hopper for the metal particles and an injector connected to the hopper. Particles introduced to the receiver are flooded with the inert gas and are transferred to the injector (which is flooded with water) by gravity. The water is displaced with gas from the generator prior to injecting the particles into the generator with a reciprocating piston associated with the injector.

Abstract: A filling element for counterpressure container-filling machines. The filling element includes: a filling tube, open at the bottom, for the liquid to be bottled; a liquid valve, arranged ahead of the inlet into the filling tube, which includes an axially displaceable valve body and a filling valve outlet chamber which leads to an inlet in a filling tube; a connecting passage extending from the front surface of the body of the filling element closing the opening of a container pressed on for filling, to the interior of the filling tube, especially the inlet region thereof; and a control valve for opening and closing the connecting passage. The control valve is capable of being actuated in common with the liquid valve in such a manner that, with the liquid valve open, it is closed in the connecting passage, and is open when the liquid valve is closed.

Abstract: A machine for filling beer kegs via a movable head which carries a change-over valve in series with a beer inlet valve, the change-over valve being arranged so that during the beer save operation at the end of each filling cycle the beer between the inlet valve and the change-over valve is isolated so that it remains sterile and can be used in the next filling cycle.
