Abstract: A Dustless Stacker hood for suppressing dust generated during the stockpiling of materials such as coal. The Dustless Stacker hood receives coal from overhead chute; the received coal falls through Dustless Stacker hood to the top of a stockpile, and the Dustless Stacker hood confines dust inside Dustless Stacker hood. The dust-laden air swirls within the Dustless Stacker hood through a recirculation pipe and back to the overhead chute to enhance an agglomeration process which causes the dust particles stick together and fall to the top of stockpile.

Abstract: A pressurized container includes a vessel defining a chamber therein. A housing that is connected to the vessel defines an outlet that is fluidly separated from the chamber by a closure member. A moveable member may be seated within and form a seal with the housing and abut the closure member.

The pressurized container might include an obstruction partially blocking an outlet path and another initiator that breaks the obstruction when activated, thereby further opening the outlet path. The pressurized container might include a main path fluidly connected to the outlet, a first secondary path that connects the main path to the chamber, and a second secondary path that also connects the main path to the chamber.

Abstract: A vent module is adapted to be mounted in a top wall of a fuel tank to vent fuel vapor from the tank to a vapor recovery canister located outside the tank. An outer shell is positioned around the vent module to define a fuel vapor transfer passageway arranged to conduct liquid fuel droplets into a liquid fuel accumulation chamber. A fuel vapor transfer port is formed in the outer shell to admit fuel vapor into the fuel vapor transfer passageway.

Liquid fuel entrained in fuel vapor is shed as fuel vapor flows laterally from the fuel vapor transfer passageway into the vent module through the fuel vapor inlet port so that “demoisturized” fuel vapor flows into the vent module and liquid fuel droplets fall into the liquid fuel accumulation chamber.

Abstract: A vapor system for a fuel dispenser having at least one vapor sensor placed along a vapor recovery line for determining the amount of captured vapor. The vapor amounts are determined by the sensor at a number of times during the fueling process.

Inconsistent results indicate either a leak within the vapor recovery line, or fuel is being drawn into the vapor recovery line. These problems within the vapor recovery system can be diagnosed and the necessary corrective steps may be implemented.
