The present invention relates to a coupling for a connecting a LNG nozzles to a LNG vehicle tank receptacle and their connection apparatus to a LNG vehicle tank for fueling.

The invention comprises a double connection system to provides additional safety to a LNG Nozzle Locking Mechanism for being locked into a LNG receptacle on a vehicle tank, by combining two different locking mechanisms: one the so-called “collet type” locking mechanism with the locking handles, and two the valved receptacle and valved nozzle approach with the rotating handle.

A distribution station includes a mobile trailer, a pump on the mobile trailer, a manifold on the mobile trailer and connected with the pump, a plurality of hoses in communication with the manifold, and a plurality of valves on the mobile trailer. Each of the valves is situated between the manifold and a respective different one of the hoses. Each of a plurality of fluid level sensors is associated with a respective different one of the hoses. The fluid level sensors are operable to detect respective different fluid levels. A controller is configured to operate the valves responsive to signals from the fluid level sensors, activate and deactivate the pump, identify whether there is a risk condition based upon at least one variable operating parameter, and deactivate the pump responsive to the risk condition.

Machine (1) for distributing a product stored in a container (30) comprising a storage zone (2) delimiting locations (4) for housing a container (30), a metering station (5) delimiting a chamber (6) housing a support (7) for accepting a collecting vessel (33), this support (7) being positioned vertically in line with an opening (8) providing access to the chamber (6), which opening is arranged in an upper part (61) of the chamber (6), the machine (1) further comprising a system (10) for emptying each location (4) for housing a container (30) through the opening (8) providing access to the chamber (6), and a unit (14) for controlling the machine (1). The metering station (5) comprises a sensor (13) for detecting the presence of a collecting vessel (33) inside said chamber (6). The control unit (14) is configured to operate the machine (1) on the basis of data supplied by said sensor (13), and the metering station (5) is equipped with a circuit (15) for the circulation of gaseous fluid providing communication between the chamber (6) and the outside of said chamber (6) through a forced circulation of air.

Embodiments of the present disclosure provide a method of forming a cover of a fuel intake system of a vehicle. The method may include providing a mold that defines a cover-forming cavity having a main body portion and a grounding strap portion connected to the main body portion, inputting a forming material into the cover-forming cavity to a specified level, allowing the forming material within the cover-forming cavity to cool and harden, separating the mold to expose the cover having an integrally molded and formed grounding strap, and removing the formed cover having the integrally molded and formed grounding strap from the separated mold.

A crossover protection system including a product transport vehicle having a tank compartment for containing a liquid product, a fluid property sensor positioned to contact liquid product stored in the tank compartment, a system controller, and a valve coupled to the tank compartment. The valve regulates a flow of liquid product from the tank compartment and has a normally locked state. The system controller may compare a received transported liquid type signal from the fuel property sensor indicative of the type of liquid product in the tank compartment and compare the type of liquid product to a stored liquid product type. If the two types match, the crossover protection controller transitions the valve to an unlocked state to allow the liquid product to unload from the tank compartment. If the two types do not match, the crossover protection controller will disable the valve from transitioning to the unlocked state.

A manifold structure for a fluid reclamation apparatus incorporated into a hydraulic system having inner and outer fluid lines and with annular containment space between the inner and outer fluid lines for capturing fluid leaking from the inner fluid line, the manifold structure being connected to least one end the inner and outer fluid lines and contains a chamber for receiving leaked fluid from the annular space and including a manifold inner sleeve to which the inner fluid line is coupled, the inner sleeve being retained within a manifold outer sleeve to which the outer fluid line is coupled and having a lateral bore extending from the chamber and through the outer sleeve for delivering leaked fluid into a reclamation line and back into the hydraulic system, the inner sleeve being rotatably mounted within the outer sleeve by at least one O-ring seated in a groove around the inner sleeve and sealingly abutting the inner surface of the outer sleeve.

The present invention relates to a method, system, and apparatus for verifying a groundwire connection prior to transferring a fluid between a tank and a reservoir. The system may comprise a vehicle comprising a tank and a groundwire, the groundwire comprising a first communicating member, a grounding unit configured to electrically ground the vehicle when the groundwire is connected thereto, the grounding unit comprising a second communicating member, and at least one processor in communication with at least one of the first communicating member and the second communicating member. The at least one processor may be configured to determine whether the groundwire is connected to the grounding unit, and facilitate fluid transfer between the tank and the reservoir based at least partially on the determination.

A signal transmitter and method. The signal transmitter includes an input to receive a sensor signal, an analog to digital converter coupled to the input to convert the sensor signal to a digital representation of the sensor signal, a communication adapter, and a processor coupled to the analog to digital converter and the signal processor. The processor contains instructions that, when executed by the processor, cause the processor to manipulate the digital representation to create a replicated digital signal that corresponds to the sensor signal and transmit the replicated digital signal to a second processor-based device through the communication adapter.
