Natural gas distribution system

A gas cylinder mounting assembly comprising:

• a gas cylinder having a first axial end and a second axial end, an internally threaded bore being disposed in said first axial end;
• a mounting plate having a first surface and an oppositely disposed second surface, an externally threaded hollow stem protruding from said first surface and being threadably connectable to the threaded bore of said gas cylinder, an internally threaded through-bore being disposed in said plate from said second surface, a plurality of internally threaded apertures disposed in said second surface;
• a valve being threadably connected to said through-bore of said plate;
• a plurality of threaded fasteners with threaded shafts and larger diameter heads;
• and
• a first collar ring having a ring plate extending at least in part across the ring and having openings for allowing the shafts of the threaded fasteners to pass through but not the heads, said ring plate being connected to said mounting plate by said plurality of threaded fasteners being received in said plurality of internally threaded bores, said valve being disposed within said first collar ring.

A truck for use in a natural gas distribution system, said truck having a body comprising:

• a plurality of separately accessible storage bays for receiving at least one crate with compartments configured to receive gas cylinders in a substantially horizontal position, each of said plurality of storage bays having a floor which is inclined with respect to a horizontal reference plane;
• a front wall that includes an air inlet vent;
• a rear wall that includes an air outlet vent;
• and
• a space providing air flow between said air inlet vent and said air outlet vent;
• and
• an electric brushless motor driven fan connected to at least one of said air inlet and said air outlet vent for promoting air flow therebetween.

A truck for use in a natural gas distribution system, said truck having a body comprising:

• a plurality of separately accessible storage bays for receiving at least one crate with compartments having an open front and being configured to receive gas cylinders in a substantially horizontal position, each of said plurality of storage bays having a floor which is inclined with respect to a horizontal reference plane;
• a front wall that includes an air inlet vent;
• a rear wall that includes an air outlet vent;
• a space providing air flow between said air inlet vent and said air outlet vent;
• and
• a plurality of gas cylinders received in said at least one crate, whereby each of the plurality of gas cylinders has a valve end facing said open front of said respective compartment.
