Abstract: A separation and containment system is provided. The separation and containment system can contain natural gasses, e.g., compressed natural gas (CNG) and liquefied natural gas (LNG), within a natural gas vehicle (NGV) service area, and separate the NGV service area from a conventional service area. The separation and containment system utilizes one or more barriers, such as industrial fabric/vinyl materials that meet various regulatory safety standards applicable to NGVs. The separation and containment system is easily constructed, dismantled, and resized/adapted in accordance with desired operating conditions.

Abstract: One aspect of the disclosure relates to a multi-prize mystery box that dynamically changes probabilities to ensure payout value in an online game. The multi-prize mystery box which dynamically changes probabilities may provide the ability to arrange multiple items in a mystery box. The probability of acquiring an instance of the second item through Nth item may be dynamically weighted based on the value of the first item.

Abstract: An improved dual seal pipe coupling is provided of the type having matingly interfitting male and female pipe fittings formed on adjacent ends of a pair of conduit members, wherein at least one of a pair of seal rings is vented at low pressure to prevent pressure build-up and potential seal ring distortion or damage upon initial assembly of the pipe fittings. The seal rings are seated respectively within a pair of axially spaced-apart recessed grooves formed on one of the pipe fittings for slidably and sealingly engaging the other one of the pipe fittings upon assembly therewith. A bypass vent is formed in at least one of the seal ring grooves, to include a shallow recessed channel underlying the associated seal ring and leading axially to a smoothly curved and generally arch-shaped relief port formed in an outboard side wall of the seal ring groove.
