  • Apparatus and method for controlling and prevention of venting of gaseous fuel to atmosphere from a vehicle tank at completion of a fuelling process
    Patent number: 6152191
    Abstract: In a gaseous fuelling system for motor vehicles, the residual gas in the fill lines is depressurized in a controlled manner to prevent gas "blow back" from the vehicle tank. Methods for blow back detection and prevention in direct and indirect fill procedures are provided.

  • Gas desiccation and contaminant disposal method and apparatus
    Patent number: 6117211
    Abstract: Water containing contaminants is removed from a gas or liquid stream and then treated to separate the water from the contaminants. The water is separated using a condenser and a semi-permeable membrane so that it is pure enough to be disposed-of in the local environment by evaporation. The accumulated contaminants may be removed separately for controlled disposal, or reintroduced into the original stream as an alternate method of disposal.

  • Split-ring breakaway connector
    Patent number: 5445419
    Abstract: A tension-activated disconnecting coupling operates by having a plug portion penetrate and pick-up an expandable locking ring. On partial with withdrawal of the plug, the locking ring is carried into a confining region where expansion of the ring is constrained and the plug is effectively locked within the coupling. Applied tension thereafter overcomes an internal spring resistance and allows the locking ring to move out further, into a space where it may expand and release the plug.
