A non-contacting gas compressor seal assembly is disclosed with an intermediate buffer chamber. The process gas is corrosive or otherwise hazardous and is contained from entering the atmosphere by pumping the barrier gas toward the process fluid. The inboard seal of the assembly is designed to maintain a sealing relationship in the event of loss of buffer gas pressure by operating as a non-contacting seal on the process fluid.

The apparatus of claim 1, wherein the second card moving component comprises a pair of speed up rollers, each speed up roller mounted for rotation on a rotational shaft. 18. The apparatus of claim 17, wherein at least one rotational shaft is driven by a motor. 19. The apparatus of claim 17, wherein at least one roller is an idler roller. 20. A method for delivering hands of randomly mixed cards from an apparatus comprising: providing at least one deck of playing cards; forming at least one set of cards within the apparatus from the at least one deck of playing cards; delivering to a delivery tray from the at least one set of cards within the apparatus a first individual set of randomly mixed playing cards for a game; delivering the first individual set of randomly mixed playing cards from the delivery tray of the apparatus, with all cards in the first individual set delivered at the same time, and then providing a second individual set of randomly mixed playing cards into the delivery tray. 21. The method of claim 20 wherein individual sets of randomly mixed playing cards are delivered to the delivery tray and there is a single delivery tray in the apparatus. 22. The method of claim 21 wherein after at least one individual set of randomly mixed playing cards is manually removed from the delivery tray, another individual set of randomly mixed playing cards is delivered fro m the apparatus to the delivery tray. 23. The method of claim 21 wherein the total number of cards in sets of randomly mixed playing cards are hands delivered from the apparatus, and the hands comprise a total number of cards that are less than the total of the at least one deck of cards. 24. The method of claim 21 wherein at least one, but less than all individual sets of randomly mixed playing cards are a subset of cards that is delivered to a dealer as a hand. 25. The method of claim 21 wherein each set of randomly mixed playing cards delivered from the apparatus to the tray is then delivered to a position on a gaming table that is distinct from a position where another set of randomly mixed playing cards is delivered. 26. The method of claim 20 wherein all sets of randomly mixed playing cards are delivered to a storage area within the apparatus without removal of previous sets of randomly mixed playing cards from the storage area. 27. A mechanism for feeding cards individually into a card shuffling or hand forming apparatus, comprising: a surface for supporting a stack of cards; a feed roller with a frictional outer surface, mounted to a rotational shaft and positioned to feed cards individually from the stack into a pair of speed up rollers; a drive mechanism that rotates the feed roller; a clutch mounted to the shaft for disengaging the feed roller from the drive mechanism as an individual card contacts a pair of speed up rollers; and a pair of speed up rollers for advancing cards into the card shuffling or hand arranging apparatus as the cards are fed, wherein the feed roller is disengageable from the drive mechanism. 28. The mechanism of claim 27, wherein the stack of cards are supported on a first declining surface, the mechanism further comprising a slideable wedge member for sliding engagement with the declining surface and for retaining the stack against the feed roller. 29.
