Abstract: A sample probe 18 for a gas sampling system obtains a highly accurate hydrocarbon gas sample from a pipeline, particularly when ambient conditions are below the hydrocarbon dew point. A compartment 20 houses a heater 44 and a pump 30, with the pump being mounted on an upper body 50 of probe 18 by suitable nuts 56, 58. A lower probe section 48 having coarse threads 76 is mounted within pipeline 10 and has a diameter D1 of at least greater than 80% of the diameter D of internally threaded opening 14 of pipeline 10. Probe 18 has large diameter upper body 50 externally threaded for mounting compartment 20 thereon. Probe 18 is preferably formed of an anodized aluminum material having a high thermal conductivity in excess of 80 BTU/Ft Hr/Ft2/° F.

Abstract: A system 10 fluidly connects a bulkhead B to a portable transport using a flexible fill line or liquid hose LH. The system includes a coupling 12 for separating the liquid hose LH from the bulkhead B during an inadvertent pull-away. An arm 24 is pivotally supported by the bulkhead B, and a support plate 36 is supported at the upper end of the arm 24. A release disk 50 is normally supported by the plate 36, and in turn supports a saddle 42 for supporting the liquid hose LH. Three circumferentially spaced pins 38 function as retaining members to support a release disk 50 on the plate 36. The components thus function to prevent the discharge end of the hose from dropping onto the ground. During a pull-away, at least one of the coil springs 64 associated with each release pin is compressed, thereby releasing the disk 50 and allowing both the saddle 42 and the liquid hose LH to become disconnected from the arm 24.
